Abstract

India is a country with a rich cultural heritage. The historical heritage dates back to centuries from primitive times. The notion of preservation of cultural heritage has been exercised for several years. With the advancement of digital technology, it has opened a new avenue for preserving the cultural heritage of a nation. Due to natural or man-made disasters, we see a loss of many historic buildings which are to be passed on to future generations. The digitization of these historical objects is very important to store these and prevent them from getting extinct. The digital preservation of various visual arts like paintings, sculptures, and ancient architectural buildings is the key technology till date to preserve the culture of a nation. This paper shows various methods of storing the historic objects by using scanners through the concept of reverse engineering. Using reverse engineering the shortcomings in the documentation can be improved. The work is concerned with preserving the cultural heritage by making the digital copy of the object and to reuse the data, when needed. When there is a need of a particular model of the past they can be revived without any loss in their heritage. The main objective of this paper is to show how to use reverse engineering method to digitalize the characteristics of the old artifacts which are considered national treasure.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd March 2018

R. D. Shambharkar | P. A. Deotale, Vivek Naik, D. K. Parbat

Abstract

The design of an industrial building is governed mainly by functional requirements and the need for economy of construction. The main dimensions will be directed by the particular operational activities involved, but the structural designer’s input on optimum spans and the selection of suitable cross-sections profile can have an important bearing on achieving overall economy. An aspect where the structural designer can make a more direct contribution is in lengthwise dimensions i.e. the bay lengths of the building. Here a balance must be struck between larger bays involving fewer, heavier main components such as columns, trusses, purlins, crane beams, etc. and smaller bays with a large number of these items at lower unit mass. An important consideration in this regard is the cost of foundations since a reduction in the number of columns will always result in lower foundation costs. In this a Case Study of Low Span Pre-Engineered Industrial building located at Vijayawada, used for the Cement Godown having building width of 15m, length of 50m and height of 5m. The minimum total weight of PEIB was found to be 22.51 Tonnes and optimized cost of this building was estimated as 12.54 Lakhs at the spacing of 7.14m as against conventional having a total weight of 34.4 Tonnes and cost of 14.448 Lakhs at the bay spacing of 6.25m.Therefore material saved by using PEIB was 11.73 Tonnes (32.85%) & net money saved by using PEIB was 1.91 Lakhs.

Abstract

The concept of Sustainable Development is an attempt to combine growing concerns about a range of environmental issues with socio-economic values. To aid understanding of these different policies a classification of different trend of thought is necessary. To meet the ever increasing needs of the rapid urbanization one such area that needs to be developed is the airport. Airports are the air transport systems nodes and have major impact on a regions economy, social conditions and environment. An Airport can only be considered to be operating sustainably if all three dimensions are balanced. Airport Sustainability can be evaluated at global, national and regional levels. This paper emphasizes the importance of regional level planning in analyzing airport sustainability. The paper presents a detailed case study of Chhatrapati Shivaji Mumbai International Airport and evaluates its sustainability on regional level under different growth and reduction scenarios. The airport concentrates on the environmental performance, global connectivity, local employment, resource optimization. Moreover, the basic concepts like waste water, air quality and noise management, solid waste management are been stressed. The construction of the airport posed a lot of hindrance for the engineers as they had to tackle the geographical and climatic conditions around the airport. Also to tackle the wildlife incursions and strikes into the airside a close watch is kept on all the birds. The increase of roadways around the airport has elevated the overall transportation capacity. Managing water resources, waste water treatment and using the recycled waste is one of the prominent traits of the airport, the peacock shaped feather skylights for natural lighting and the use of energy efficient materials in construction has led the Mumbai Airport from a worn airport to one of the worlds top airport giving it a gold certification from LEED[4].

Mandakaruhi Rymbai | Peerzada Jaffar Abass, S. Ganesh

Abstract

Antique structures are prone to be afflicted by the fluctuating load or the change in the environment circumstances such as effect due to earthquake load, wind load and other unpredictable factors. Rehabilitation of such structure will cost a lot and the alternate way to reduce that cost is by choosing the structure to be bolster with various type of strengthening technique using distinct material. One of the best technique used is by wrapping different material from the external surface. Retrofitting of material is a widely-used method and has been followed since long time back especially during this time period where natural calamities can happen anytime anywhere, so people are inclined to apprehensive with their structure condition. The retrofitting material being used here are steel jackets, elastic tapes, rubber tubes and glass fiber reinforced polymer(GFRP) with epoxy resin as adhesive. The concrete column used is having the dimension of 80mmX80mmX300mm a type of short column. The wrapping location tested at two specific places- first type wrapping is to be done at the distance 100mm from both edges of the columns and in the second type the wrapping location to be done is 100mm to 200mm distance of the column i.e.at the center of the column. The columns are both end fixed and two grade of concrete used for the tested columns i.e.M20 and M25 for confirmation. The cracking load that can be absorb by the columns were tested by using digital compressive testing machine. Each grade of columns tested on 28days curing into three category- first categories were the standard columns, the second category in which the columns were first subjected to the compressive load then retrofitting done after subjecting to load for the second-time testing and the third category in which the retrofitting of columns was directly followed after its 28days curing then the columns were subjected to the compressive load. The results obtained were being simulated into the ANSYS software and the finite element analysis is done which gives similar result as compared to the experimental values.

A Comprehensive Study of Surface Geometry, Humidity and Dry Patches on Falling Film Heat Transfer

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 5th February 2018

Rajneesh Kaushal | 

Abstract

Heat transfer through falling film evaporation has wide industrial applications like in cooling towers of thermal power plants and refrigeration and air conditioning industries. There are various factors which can improvise the falling film evaporation performance or effectiveness like enhanced tube surface geometry and working conditions. The relative humidity of air has a great influence on falling film evaporation. Also, dry out of the surface of tubes because of excessive thermal loading or less flow rate of cooling water film has a significant role in the effectiveness of falling film evaporation. Thus, a comprehensive review has been conducted to study the effects of surface geometry (horizontal smooth and plain tubes, porous structures, finned and enhances surfaces, liquid feeder configuration etc.), falling film pattern, dry out crisis phenomenon and relative humidity of the air. Finned and enhanced surfaces were supposed to increase the heat transfer rate than the others. Dry out a phenomenon which occurs due to instability problem can be checked by stability factor or minimum wetting rate. The humidity of air leads to increment in mass transfer coefficient and heat flux.

A Detailed Review on Alkali-Activated Slag (AAS) and Fly Ash Based Concrete

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 5th January 2018

Sonal Banchhor | Dr Meena Murmu, Dr Shirish.V.Deo

Abstract

In the present world, the technology is changing at a high pace, concrete is one among them and has turned into a key piece of our lives. With each passing day, the use of cement is expanding at a high rate. One of the core constituents of concrete is Portland cement. With the increase in utilization of concrete, the manufacturing and consumption of cement have increased drastically. Despite the fact that bond has uncommon restricting properties and is extremely apt for use in concrete, the assembling of concrete outcomes in the discharge of a lot of CO2. Due to this, researchers have commenced finding alternatives to cement that are economical as well as environment-friendly. Fly ash and Ground granulated blast furnace slag are industrial by-products which postulate admirable binding properties to concrete and accommodate as a supersession of cement. These alternatives are generally termed as Supplementary cementations materials (SCMs). The utilization of these materials not only avails in reducing the consumption of cement but withal accommodates as an efficient method for their safe disposal. This paper analyses the effect of utilizing these materials that can be utilized in concrete as partial replacement of cement. The literature review of sundry researchers reveals that a single alternative cannot provide all the benefits that cement does. Rather, a suitable combination of these products can be incorporated in concrete to provide properties better than that of Portland cement concrete. And research in the field of AAS and fly ash concrete states that this new material is high potential to replace an alternative to Portland cement. This article presents an in-depth review of alkali-activated slag and flies ash-based concrete. The paper covers composition, mixing and curing process, benefits, limitations, and applications of AAS and fly ash-based concrete.

A Hybrid Book Recommender System Using Feature Combination Technique

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 11th June 2018

Chitresh Kumar Singh | Dr. Manash Pratim Dutta

Abstract

Recommender systems are used to provide personalized recommendations to users in the e-commerce industry. Two main approaches for the recommender systems are collaborative filtering and content based filtering. In collaborative filtering, a user’s preference is calculated by his similarity to the other users. If a user has already rated or bought an item, then the preference for another user is calculated by his similarity to the other user. In content based filtering, the approach is item based, which means that if user has already rated or bought an item, then his preference for another item is based on the similarity of the first item to the second. Both of these filterings are combined in the form of hybrid recommender systems, and when weights are assigned to these recommendations, the system so developed is known as aweighted hybrid recommender system. An often neglected feature in recommender systems is that of ‘Serendipity’. Serendipity means introduction of newer items into the recommender system, which are likely to interest the user. In this paper we have presented a suitable model, based on the feature combination technique, which introduces serendipity feature into the recommender systems.

A Mathematical Model of Fluid Flows in Open Rectangular and Triangular Channels

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 22nd January 2018

Kavyashree B. A | Dr. P. N. Chandramouli

Abstract

Flow in a closed conduit is regarded as open channel flow, if it has a free surface. This study considers the flows of an incompressible Newtonian fluid through open rectangular and triangular channels. The effects of channel slope, energy coefficient, channel top-width and roughness coefficient on velocity distribution in the open rectangular and triangular channels are investigated. The governing equations of the flows are continuity and momentum equations. The finite difference approximation method is used to solve the governing equations because of its accuracy, stability and convergence and the results are represented graphically. It is found out that the velocity of flow increases as depth increases and an increase in the channel slope, energy coefficient and top-width leads to an increase in flow velocity whereas increase in roughness coefficient leads to a decrease in flow velocity for both rectangular and triangular channels. This study goes a long way in controlling floods, construction of channels and in irrigation

A Mechanical Analogy for Heat Transfer in Surface Films with Transformations

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 20th December 2017

Rahul Basu | 

Abstract

A model for describing effects of a variable frequency heat source on the surface of a film is developed. The effect of material parameters is analyzed to describe possible attenuation of the thermal fluctuations and sustaining these through coupling with the surrounding matrix. Application to amorphous alloy formation with phase field concepts is described. An analogy with a damped oscillator driven by surface fluctuations gives the relation of non-dimensional parameters like the Stefan, Fourier and Biot numbers to surface heating with convection. Recent discoveries of high-temperature superconductivity in the femtosecond regimes are included. Impurities and stress fields caused by large oxygen atoms and interaction with the phonon field may be responsible for such effects especially in the "crust" of oxide films. Phonon interactions with driven oscillators in the film may be possible and design of suitable materials to give sustained longer duration high-temperature effects is outlined.

A Novel Technology for Treatment of Oil Field Produced Water of Upper Assam basin

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 16th April 2018

Konwar D | Gogoi SB, Machahary B

Abstract

Produced water (PW) is a complex mixture of organic and inorganic compounds and the largest volume of by-product generated during crude oil recovery operations. It contains substantial quantity of contaminants and other suspended particles and so, it cannot be disposed directly or cannot be injected to the sub-surface for secondary recovery purposes keeping in view of the environmental concerns. Therefore, evaluation of PW characteristics is important and essential for both environment and reservoir management. This study deals with quantification and qualification of physical and chemical parameters of PW collected from different depths and horizons of Upper Assam oil fields and treat it by a self-designed novel technology. The characterization of PW is analyzed and compared with the World Health Organization (WHO) specification to meet the minimum discharge regulations of waste water for a greener ecosystem. The novel technology is the design of the treatment technology by intervention of different membrane technologies. Hollow fibre set-up was used for the treatment of PW by incorporating filter membranes of the order of micro, ultra and nano sizes. The fouling effect of the membranes were found to be minimum. All the membranes showed optimum efficiency with respect to their treatment performances.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd March 2018

Vikas Yachawad | S. V. Bakre

Abstract

From the past some decades we dealt with several earthquakes, which proved that the influence of the effects induced due to the earthquake is severe in the irregular structure. As behavior and instance of these natural hazards are unpredictable, we can just design the structure which can resist the effects induced by them hence several codes have been developed to differentiate these type of vertical and horizontal irregularities. Some critical measure also given in these codes to deal with these type of irregularities. The objective of this study is to carry out the seismic analysis of vertically irregular buildings as per IS1893:2016 and compare the effects of those irregularities with the analysis results of the regular building structure. A regular and three stepped building with a different configuration has been taken for the analysis. Seismic analysis of those buildings has been carried out by using equivalent static analysis (ESA) and response spectrum analysis (RSA). Use of magnification factor has been taken into consideration to scale up the response spectrum analysis results up to the results of an equivalent static analysis. Regularity index for an irregular building has been calculated to compare modification in the time period of same irregular building over code specified time period and thereby modification in spectral acceleration and base shear. First mode participation factor and time period of an irregular building are found to be lesser than the regular building whereas the base shear of an irregular building is higher than the regular building.

Mahendra Umare | V.P. Varghese, A M Badar, D P Singh, N R Dhamge

Abstract

Geographically, India is blessed with great peninsular region well connected by ports. Presently, all the ports in India account for handling almost 90 percent of its export and import trades. However, its contribution is just 1 percent against by railways & roads, which accounts 9 percent and 6 percent of the total goods transportation in India respectively. It is estimated that India has about 42 percent of the proportional share of goods trade in its GDP growth whereas, other developed countries has about 70 to 75 percent. It reflects that India has great potential in ocean economy. Therefore, keeping the focus on blue economy development, India can integrate its ports development and can have more sustainable business solutions for its overall economic, social, and socio-economical growth. This paper elucidates the status of the contribution of blue economy in India’s development and opportunities in various sectors of the blue world in achieving a growth of infrastructure.

A Review of Codes on Building Irregularities for Seismic Analysis

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Meenakshi Landge | Dr. R. K. Ingle

Abstract

Possibility of damage happening during earthquake ground motion is more where there are occurrences of structural weakness and this weakness generally produced because of the irregularity.The presence of structural irregularity changes the seismic response and the change in the seismic response depends upon the type of structural irregularities. In this paper, criteria and limits specified by IS 1893(Part 1) for different types of irregularities are discussed and standards defined by other countries (ASCE-7-10, NBCC2005, TEC2007, NZS1170 and EC8: 2004) have been compared. The code’s main advice for the designers is to avoid irregularities altogether if possible.Alsoto avoid casualties, architects should design appropriately and understand the dynamic behavior. To do that, the basis of seismic codes which are substantial bases should be used in architectural studies

A review on Application of Coconut Shell in Concrete

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 27th February 2018

Snehal I. Randive | Shilpa V. Patil

Abstract

The rising cost of material is a matter of concern in this developing construction environment. The reason for the increase in cost is high demand and less availability of materials. The research on alternative materials which can reduce the cost of construction and on the other hand increases the strength and durability of structures is on demand, with regard to this the research on waste material such as fly ash, rice husk, slag and sludge is going on. Coconut shell is an agricultural waste which is abundant to the environment and also raises the risk to health as well as environment. From the previous research, it has been found that coconut shell ash (CSA) can increase the strength of concrete and coconut shells can be used as a replacement to the aggregate in concrete. Silica is important oxide present in coconut shell ash that can help in increasing strength of the concrete. Therefore the research in the extraction of silica from CSA as well as the use of coconut shell either in the form of reduced size or the burnt ash is going on. The present paper provides a review of the application of coconut shell in the concrete along with details of experimental work done by various researchers for investigation of the use of coconut in the construction industry. The paper describes the use of coconut shell as partial replacement to the coarse aggregate as well as use of CSA for partial replacement of cement and use of silica extracted from CSA as an admixture along with their effects on properties of concrete

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 22nd January 2018

Omkar Ganesh Bhegade | Himkedar Jadhav, Prof.M.Mahajan,Prof.D.Shastri ,Dr.N.Patil

Abstract

This paper looks at the research that is being carried out on use of Graphene as an electrode material for supercapacitors which may be the replacement for the lithium ion batters in future. It also discuss about the scope of graphene based supercapacitors in various fields. Science and technology have been advancing rapidly over the last few decades; storing the energy has always been a problem. The problem faced by conventional energy storage system is that a battery can potentially hold a lot of energy, but it can take a long time to charge and a capacitor, on the other hand, can be charged very quickly, but cant hold that much energy comparatively. The solution emerged was the supercapacitor that is able to provide both of these positive characteristics without compromise. Currently, research is being carried out on enhancing the capabilities supercapacitor and Graphene is proving itself to be the best electrode material for it. Graphene is a nanomaterial of 2D flat monolayer carbon (bonded in hexagonal lattice). Graphene is a parent of all carbon allotropes with versatile properties

A review on the biomass energy resources and conversion technology in India

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 5th July 2017

Amit Kumar | Dr. Rajakumar D.G

Abstract

Sustainable economic development is closely linked with the energy availability. The demand for energy continues to increase steadily from last several decades, due to rapid industrialization and globalization. Most of the world’s commercial energy needs are met by fossil fuels coupled with negative environmental effects. The burning of the fossil fuels is a big contributor for increasing the level of CO2 in the atmosphere. To combat global warming and other environmental problems associated with these fossil fuels many countries, including India, are increasingly adopting renewable energy sources. Such energy sources generally depend on energy flows through the earth’s ecosystem from the insolation of the sun and the geothermal energy of the earth.

A Review Paper on Investigation into the Effect of Pounding on High Rise Structure

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 1st March 2018

Bhagyashri Thele | Dr.Valsson Varghese

Abstract

It has been widely seen that when an earthquake occurs it causes large and intense shaking of the ground. So the building or the structure of any shape, size or of any height will experience the motion at its base. The level of damage caused by an earthquake on a structure depends on the intensity of release of strain energy and the duration of shaking. The amplitudes are largest with respect to the large earthquake and the duration of shaking generally increases with the size of an earthquake. When two adjacent building vibrates out of phase the collision occurs due to the insufficient separation or gap this phenomenon is known as pounding of the building. This paper includes the study of pounding between adjacent buildings with same or different properties. Lump mass system is considered using MDOF system. In this time history analysis is carried out using past earthquake of Imperial Valley

A State-of-the-Art Review on Fatigue Analysis of Steel Bridges

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd March 2018

Sushank Dani | L.M.Gupta

Abstract

Fatigue is a localized and progressive cumulative damage accumulation due to continuous cyclic movement on a structure. The effects due to this can be dangerous as compared to conventional static load. On bridges, fatigue occurs due to the passage of vehicular load. In railway steel bridges, there are structural members with low dead load stresses but high live load stresses due to movement of wagons and locomotives. These high live load stresses cause a decrease in strength well below the design stresses. This, in turn, reflects the reduction in useful life of the bridge. Here, live load stresses are assessed for different members and details of bridges. Various analytical methods suggested such as nominal stress method, Hot spot stress method, Effective notch method, etc. The results of these methods are compared with the field measurement data obtained from strain gauges or structural health monitoring methods. The nominal stress method has been mentioned in various codes like BS 5400: 1980 (Part X), Steel Bridge Code, RDSO, etc. While the hot spot stress method depends on the finite element analysis of bridges. It finally concludes with the calculation of stress concentration factors for a particular detail. The failure due to fatigue does not depend upon the maximum stress, but on the stress range (absolute difference of maximum and minimum stresses) and the number of cycles corresponding to that stress range also called as stress history. Using the S-N curve and Palmgren-Miner’s cumulative damage rule, the damage assessment for each moving load is calculated followed by useful life estimation of a structure. This is a brief methodology for nominal stress method. The revised fatigue Appendix ‘G’ in Steel Bridge Code, RDSO has incorporated this method in addition to geometrical stress method (or hotspot stress). The nominal stress method is widely used for fatigue evaluation and design of steel bridges, but the hot spot stress method is more accurate and effective. Though the field measurement data presents most accurate information for determining the fatigue life of the structure, the above said two methods can be applied successfully to fatigue analysis and design. The main objective of the study is to find the difference in methodologies for assessment of fatigue and its application on railway steel bridges. Recently, a number of studies have been started on the use of probability concept in fatigue life determination of bridges. Though, these require combined basic of reliability and probability so they are more dependent on experimental and statistical data. Based on the above analysis, a predefined maintenance and inspection schedule can also be prepared. This schedule depends upon the service life of each structural member or details

Abstract

manufacturing of bulk nano structured are in high demand in today’s industry because of recent development and application of advanced materials. Many traditional machining processes were used but none of them have been able to produce complex shapes precisely at low cost. In order to overcome this difficulty Large–strain extrusion machining (LSEM) is introduced. It is basically a fabrication process. It is a single step manufacturing process. It is a method of severe plastic deformation (SPD) which is used particularly for machining bulk nano structured materials. It is a low cost manufacturing technique with advantage of machining and controlling dimensions simultaneously. Different shapes such as foils, sheets and bars of controlled dimensi ons are produced with controlled geometric parameters of the deformation using large strain extrusion machining. The paper reviews all the characteristics of large strain extrusion machining, its background, its developments, effect of various parameters ( rake, feed, speed) on mechanical properties of chips, its mechanics, study of chips at microstructure and nano level. Effect of strain, porosity, hardness and other properties on chips have also been studied.

In this stage, planners and contractors using their experience plan the project considering time, cost and quality constraints. In recent time, importance is being placed on using different tools like GIS in the preconstruction planning stage. In planning a water supply distribution scheme, an information system is needed that will help the construction planners to plan the project. Geographic information system is a computer based system that is used for storing, manipulating, and analysing large amount of data. This paper focuses on the water supply distribution scheme of a village Mahuli, in Maharashtra, India. In this paper study of application of GIS on one of the aspects of water supply preconstruction planning, i.e. distribution pipeline network, details and analysis in GRAM++ is done. The purpose of the study is to know the advantages of using GIS and achieving time effectiveness.

A study on the pH Value of Fly Ash Concretes

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 22nd January 2018

Dr.Mudimby Andal | Dr. T.D.Gunneswara Rao

Abstract

Use of fly ash in concrete as replacement to cement is an established practice accepted all over the world. The reason is mainly due to the fact that replacement or addition of fly ash reduces the cement consumption and make the concrete economical. Flyash concretes are more durable than conventional concretes. However, the addition of fly ash in concrete decreases the pH of concrete and reduction in pH value disturbs the passivation layer formed around the rebars. The passivation layer is formed around the rebars in concrete due to the higher alkalinity of concrete. Thus the addition/replacement of cement by fly ash affect the pH and thereby the alkalinity. This article describes the effect of replacement of cement by fly ash on the pH value of the end product i.e., fly ash concrete. Fly ash concrete and mortar specimens are cast and tested for pH. It is found that replacement of cement by fly ash reduces the pH of the matrix. With the increase in the age of fly ash concrete reduction in pH value is found to be more. This indicates that the reaction of fly ash with Calcium Hydroxide present in concrete with time reduces the pH value. It is concluded that the treated flyash would be more effective and beneficial than replacement of cement with untreated fly ash..

A Study on Web Buckling Of Plate Girders

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd March 2018

Neeraj Singh Thakur | D. Datta

Abstract

The plate girder is fabricated from plates and the designer has greater freedom to vary the section to correspond with changes in the applied forces. Thus variable depth plate girders have been increasingly designed in recent years. For a given bending moment the required flange areas can be reduced by increasing the distance between them.Thus for an economical design, it is advantageous to increase the distance between flanges. To keep the self-weight of the girder as the minimum, the web thickness should be reduced as the depth increases, but this leads to web buckling. Web buckling considerations being more significant in plate girders than in rolled beams since Rolled beam section are manufactured by keeping depth to thickness ration such that there will be no local bucking in the web. The web buckling of plate girder can be avoided by using the thicker web or by using stiffeners.In this paper feasibility of using stiffeners to reduce the dead load, material and fabrication cost of plate girders is studied. Use of transverse stiffeners lead to creating tension field in the plate girders prior to buckling and this tension field helps to increases the buckling resistance of web. In this paper as per IS: 800:2007 design of plate girder is done. The optimum section for the given load is found out by varying the thickness of web and number of stiffeners in different trials. Finally, the most suitable section for a given load is proposed in this paper

Accelerating Batched Perfectly Stirred Reactor (PSR) Calculations Using General Purpose Graphics Processing Unit (GPGPU) Computing

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 16th June 2017

Sudip Adhikari | Alan Sayre , Abhilash J. Chandy

Abstract

Detailed analysis of efficiency and pollutant emission characteristics of practical turbulent combus- tion devices using complex combustion kinetics often depend on the interactions between the chemistry of both gaseous species and soot, and turbulent flow char- acteristics. Modeling of such combustion system often requires the use of chemical kinetic mechanisms with hundreds of species and thousands of reactions. Per- fectly stirred reactors (PSR) are idealized reactor en- vironments, where the reacting species have high rate of stirring, and the combustion products are uniformly distributed inside the reactor. The fundamental equa- tions describing a PSR constitute systems of highly nonlinear algebraic equations, due to the complex rela- tionship between the net production rate of the species and the species concentration, which ultimately makes the equations stiff, and the solution of such equations become highly compute-intensive leading to the need for a efficient and robust solution algorithms. Graph- ics processing units (GPUs) have widely been used in the past as an effective alternative to central process- ing units (CPUs), and highly parallel threads of GPUs can be used in a efficient manner to improve the al- gorithm performance for speeding up the calculations. A highly parallelized GPU implementation is presented for a batched calculation of PSR model.

SachinAnant | BiradarVinayak T., Basavaraj N. , Pramath N P , Sharat VD

Abstract

The aim of our project is to take a system wide approach to preventing the machine accident.The system includes not just the machine and the operator; but rather it includes everything from the initial design of the machine to the training of every one that is responsible for any aspect of it, to the documentation of all changes to regular safety audits and finally a corporate culture of safety first. Design is the part of a machine life where the greatest impact can be made in relation to avoiding accidents. The designer should ensure that the machine is safe to set up and operate, safe to install, safe to maintain, safe to repair and safe to decommission. Although safe operation is usually at the forefront of a designer mind safe maintenance and repair should also be a high priority. Around 50% of fatal accidents involving industrial equipment are associated with maintenance activities and design contributory factor in some 32% of these fatalities.

Advance Biogas System for Irrigation - A Typical Application

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 22nd January 2018

Dr. Amol B. Ubale | Priyanka Tupe-Waghmare,Swapnaja A. Ubale

Abstract

Anaerobic reaction of the organic substances like vegetable/food waste, animal/human waste and agricultural waste produces gas called as Biogas. This gas chemically consist of CH4, CO2 as major content( 50-75% & 30-40%) and other constituents such as N, H2S, H , O2 and H2O vapour in small amount (about 10% all). It is well known fact that CH4 is a good IC engine fuel. As the gas mix with air easily it can be used as fuel in compression ignition (CI) engines. CO2 content from it can be either reduced or completely removed by simple water scrubbing process. The burning of this gas gives clean energy with low emission. If it is used in compressed form in cylinders, it can be a supplement to compressed natural gas (CNG) and liquefied petroleum gas (LPG) and. Present study has demonstrated a small capacity biogas plant which is constructed using kitchen waste as feed stock. The gas produced from it is supplied to computerized CI engine test rig of 3.5 KW. Various tests were carried out at different speeds and load conditions. Typical running conditions are demonstrated with 2300 rpm and 20 N-m. The system works fairly well at low load conditions.

Advance Cooling Of Radiators by Using Nanofluids

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 11th June 2018

Roheshkumar S. Lavate | Rameshwari V. Lalge

Abstract

After combustion of fuel the large heat is liberated inside the combustion chamber. The internal combustion engines are cooled by using either a liquid coolant or air. In air cooling system the air is flow over and around the cylinder, cylinder head and cylinder fins and carry away the heat. In water cooling system the coolant is circulate through a water jacket of cylinder head and cylinder wall. This coolant has absorb heat from the engine and dissipated to atmosphere by the device known as radiator. The Radiator contains number of horizontal tubes surrounded with fins. The heat is carry away by three modes of heat transfer namely Radiation, conduction and convection. Most of the convection takes place because of air flowing around the radiator fin and tube assembly and Conduction takes places between radiator tubes and fins. These coolant offer low thermal conductivity and poor heat transfer characteristics. There is large scope to design a high energy efficient, compact and light in weight automobile radiator by development of advanced nanofluids, which have better conduction and convection thermal properties and better heat transfer characteristics. This paper will introduce new concept of radiators that can adopt the high performance nanofluids. This advance cooling system also raises the total mechanical efficiency of the engine

Advancement in an Engineered Cementious Concrete

Abstract

A review of representative research on the behavior of PVA-ECC concrete under flexure and shear action. Concrete is most widely used material but its brittle behavior is one of the most serious problem. This problem can be overcome by using ECC concrete which contains PVA fibers in place of course aggregates and fly ash replacing cement partially. The various materials which are to be used are ordinary Portland cement, fly ash, PVA fiber, Sand, Superplasticizer and water. Superplasticizer is to be used to control rheological properties of fresh concrete. PVA fiber are selected because they have strong bond with the concrete matrix, strain hardening property and provide pseudo-ductility to the concrete thereby increasing flexural and shear strength. The seismic disturbance to a structure can be partially stabilized with the help of ECC concrete

Advances in Aircraft Mechanical Systems and Components

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 5th July 2017

G. BhavaniSankar | H. N. Bhaskar

Abstract

Aircraft is a complex system of systems. Structural elements are complemented by the Avionics and Mechanical Systems. Avionics would provide the communications, navigation, other control functions and commands. The Mechanical Systems would execute these and provide the power to realize a safe flight starting from takeoff to landing. Each system has its role to play in the successful mission of the aircraft’s each flight. Each system will have sub-systems and components to achieve their functional requirements and meeting the reliability, maintainability and safety (RMS) requirements. It is a known fact that many technological advances originate from the Aerospace industry and trickle down to other walks of life. In recent years, the aviation business has entered a major growth period with increased air transportation demand projected for the future. On the other hand, the rising awareness of environmental issues on a global scale necessitates a reduction in substances of concern i.e. decreased greenhouse gas emissions. Furthermore, as the international demand for fuel increases, fuel prices are rising, and the aviation business is urgently requesting better fuel efficiency for economic reasons as well. There is also serious research happening in the area of alternate fuel, fuel cell and all electric aircraft. These needs, currently drive the requirement for newer technology and changes in how aircrafts are made and flown. Thus energy consumption of each system is one area that is scrutinized closely. Going one step ahead the exergy analysis to minimize the entropy generation by these systems and to curtail the endogenous avoidable and exogenous avoidable parts of the exergy destruction occurring in each component are extensively used in Propulsion System and ECS development. Weight reduction is another important aspect in all these systems. Landing Gear System (LGS) weight is generally about 4.0% of the aircraft take-off weight. Developments like equipping composite braces on the main landing gear, electrically actuated Landing Gear are some examples of weight reduction in LGS. Advances in these systems not only aim at improving inflight performance but also look into the energy and fuel saving during ground handling, maintenance and thus reducing life cycle cost. This paper details the technology and the innovations that have gone in to evolving these systems over the years both at system level and component level. The paper also looks into the emerging trends in the design and development of these systems. The trends in developing new configurations, evolving the new systems’ architecture, meeting the demanding new requirements at component and system level, using latest software resources for mathematical modeling and simulation, conducting rigorous tests at component and system level at ground and flight test phases and finally meeting the certification requirements are touched upon.

Abstract

The work reported here to show the effect of biplane configuration on aerodynamic performance of the NACA 0012 symmetric airfoil. The computational analysis was performed with the help of CFD program which were GAMBIT and FLUENT. The flow around the airfoils was incompressible, steady state, two dimensional Nevier-Stokes equations with different turbulence models were used to simulate the flow nature of aerofoils. This analysis have been carried out by varying the gap between the aerofoils such as 25%C, 50%C, 75%C and 100%C at various angle of attack and operating at Reynolds number 3×106. An interference effect occurs in gap between biplane configurations which can be varied with differ in angle of attack and chord length. The 50%C gap between the aerofoils shows the maximum increase in lift co-efficient. It is observed that biplane configuration provides greater maneuverability performance such as loops and rolls. The computational solutions gives information that increase in lift co- efficient at low speed conditions with little penalty in drag co-efficient. Computed results have been validated with existing experimental data.

Abstract

Drought is one of the short-term extreme events. There is no operational practice to forecast the drought. Drought indices play a significant role in drought mitigation. In the present study, Pallar basin which is present in Chittoor District of Andhra Pradesh, which are seriously prone to drought, has been established using meteorological and remote sensing based agricultural droughts indices. The meteorological droughts indices was Standard Precipitation index (SPI)and the satellite data based agricultural drought indices was Normalized Difference Vegetation Index (NDVI), Normalized Difference water Index (NDWI). The meteorological and remote sensing based agriculture drought indices has been determined and compared for the period of 2000, 2005 and 2010. The result shows from SPI Index the year 2005 is wet year and the year 2000 and 2010 are dry year. From NDVI index the year 2005 is having more vegetation area and the year 2010 is having less vegetation area. Hence, agricultural drought risk mapping can be used to guide decision making processes in drought monitoring, and to reduce the risk of drought on agricultural productivity.

An Experiental Investigation on Fresh And Durability Properties of Self Compacting Concrete using Various Blended Cements

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

P.Manjula | Prof C. Sashidhar

Abstract

Self compacting concrete is a concrete that can flow through congested reinforcing bars with elimination of compaction, and without undergoing any significant segregation and bleeding. SCC requires high volume of cement and sand. Use of high volume of cement increases CO2 emissions and leads to the green house effect, and continuous digging of sand from rivers causes depletion of rivers and creates lot of environmental problems. Use of supplementary materials may reduce the above problems with-out altering the SCC performance. This paper presents the fresh and durability properties of SCC using supplementary Cementatious materials like fly ash (25%), silica fume (10%) or Metakaolin (10%) robo sand in place of natural sand; coarse aggregate of size 12mm; GLINIUM 8630 as super plasticizer. The mix proportions were calculated by following European Federation of National Associations for Representing Concrete (EFNARC) guidelines. Mixes were prepared and tested for results. Slump flow, V-funnel and L-box tests are conducted to examine the fresh properties, acid (HCl&H2SO4) resistant and dry shrinkage are for the durability studies. This study shows that quaternary blended cement gives fresh properties and durability properties better than the ternary blended SCC

Abstract

The demand to make this material lighter has challenged scientists and engineers alike. The challenge in making a lightweight concrete is decreasing the density while maintaining strength and without adversely effecting cost. One such alternative is coconut shell (cs), as coarse aggregate in the production of concrete. Even though coconut shell possesses several desirable properties, its relative low tensile strength and deformation properties prompted many researches to work on to improve these properties. One such development of improving or modifying the properties of concrete is by supplementing the mineral admixtures with coconut shell concrete. Experimental investigations and analysis of results were conducted to study the compressive and flexural strength behavior of concrete with varying percentage of mineral admixtures. The concrete mix adopted were m25 with varying percentage of mineral admixtures ranging from 2%, 4%, 6%, 8%, 10%, 12%, 14%, 16%, 18%, 20%, 22%, 24%, and 26%. On the analysis of result the concrete with mineral admixtures in coconut shell had improved performance as compared to the ordinary concrete.

Abstract

Among the group of super hard alloys, titanium is one of the fastest growing materials used in aerospace applications. The prime rationale for designers to choose titanium in their designs is its relative low mass for a given strength level and its relative resistance to high temperature. One drawback of these titanium material is their poor machinability. Many researches are going on to develop a machining technique that improves the machinability of hard materials. One such method that is under research for is cryogenic machining. In this type of machining the traditional coolant is replaced by the Liquid Nitrogen. Only the Liquid nitrogen is more preferable in machining because it is cost effective, safe, nonflammable and environmental friendly gas, in addition to that it cannot contaminate work piece, no separate mechanism for disposal .In this paper a machining test is conducted on the titanium Grade -2 material and the machining parameters temperature at the cutting area, cutting forces , power consumption , surface roughness are found by varying the speed, feed , depth of cut for the both normal machining and cryogenic machining.

Abstract

Machinability is a property or quality of any material that can be clearly defined and quantified, to indicate how easy (or difficult) it is, to perform machining operations on it. In fact, the term is ambiguous, but the machinability of any material can be assessed using parameters like (i) tool life (ii) cutting forces (iii) power consumption (iv) surface finish and (v) chip morphology. In the current paper machinability of the materials like Mild steel, Stainless Steel and Titanium are studied; however special emphasis is given to Titanium as it difficult to machine due to high cutting forces, temperatures, chemical reactions with tools, and a relatively low modulus of elasticity. Titanium does not form a built-up edge on tools which is a common problem while machining steels and this result in good surface finishes even at low cutting speeds. The lack of a built-up edge, however, increases the alloying and abrading action of the thin chip which races over a small tool-chip contact area under high pressures. The combination of above characteristics and relatively poor thermal conductivity of titanium results in abnormally high tool-tip temperatures. To overcome this, one of the best techniques available is Cryogenic Machining. Cryogenic machining is a process in which the traditional lubrocooling is replaced by liquid nitrogen (LN2). Liquid nitrogen is more preferable in machining to dissipate heat generated because it is cost effective, safe, non-flammable and environment friendly gas. In addition, it does not contaminate work piece and no separate mechanism for disposal is required. In the current paper, the overall machining is done on turning machine and the parameters like Cutting forces, Surface finish, Temperature at cutting area and power consumption are obtained for the three materials. The overall results are tabulated and the conclusions are drawn accordingly. The main objective of the research is to improve the machinability of materials by using Cryogenic Machining techniques.

Sandeep Gowda M | Ashwin K N,J K Dattatreya

Abstract

The objective of this study is to analyze the effects of steel fibre reinforcement in concrete for different dosages. Concrete mixes were prepared using M30 grade concrete with hooked end steel fibres of aspect ratio 80 (L/D where L=60mm and D=0.75mm) were added at a dosage of 0.25%, 0.5%, 0.75%, and 1.0% to volume fraction of concrete. The flexural strength was determined using a two point loading system. Load v/s deflections graphs were plotted for various percentages of fibre concrete specimens. Test results were compared with plain concrete specimen. From the experimental work it is found that with the increase in the steel fibre content in concrete there is an increase in flexural strength. The flexural strength at 1% steel fibre content is 9.1N/mm2 and the 0% fibre content is 5.78N/mm2 hence increase of 57.43% flexural strength is obtained.

S.D. Mankar | S.S.Jamkar

Abstract

The present investigation is to use the waste product from steel industry which is helpful in cement production if it is ground at a fineness of cement which also helps to reduce the carbon emission. Ground Granulated Blast Furnace Slag (GGBFS) is used as a mineral additive for concrete production and substitutes for cement, it behaves as a binder material along with cement.The optimum dosage of GGBFS as cementitious material is characterized by high compressive strength, low heat of hydration, resistance to chemical attack, better workability, good durability and cost-effective.This paper presents a laboratory investigation on optimum level of ground granulated blast-furnace slag on compressive strength of concrete.18 concrete mix sample were cast with water to cementitious material (w/cm) ratio 0.32 and 0.30 each; using GGBFS as partial replacement of cement from 0% to 50% at an interval of 10%. The specimens were cured for 28 days in potable water. The compressive strength of concrete is examined.The test results revealed that the compressive strength of concrete mixtures containing GGBFS increases as the amount of GGBFSincrease, upto certain limit. The optimum dosage of GGBFS is found at. This can be explained by the presence of unreacted GGBFS, behaves as a filler material in the paste and not as a binder

An Experimental Study on Suppression of Vortex Shedding with Different Structural Configurations

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 22nd August 2017

Sanal M V | Prof. Sunil A S

Abstract

The flow phenomena around bluff bodies or non-streamlined bodies in fluids are always of some engineering importance. Most of the engineering structures like buildings, bridges etc. can be considered as bluff bodies as far as the air or water flow in which the structure is being situated, is considered. This paper aims at the study of vortex induced vibration and suppression of the VIV on some common models of structures which can be considered, of having some engineering importance. The main parameter associated with the VIV formation is the Strouhal number (St.) which is the non-dimensional frequency of vortex shedding. The VIV was captured by using Fieldpaq Dynamic Signal Analyzer which has frequency ranges from 0 Hz to 40 kHz. The cylinders with varying number of fins and splitter plate length are tested. The methods to control VIV can be classified into three as active, passive or compound method. The passive method, would give some structural modifications on the model and considered to reduce the VIV formation. On the other hand,. Among these, the active and compound methods are costlier compared to the passive method. Therefore on an economic point of view the engineers are keen to develop more and more methods to suppress the VIV effectively with a lesser cost i.e., by employing the passive method. My study is on employing the model with straight fins.

Analysis and Design of R.C.C. T-girder Bridge under IRC Class AA and Class A Loading

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Sudarshan Prabhakar Patil | Kameshwar Rao Tallapragada

Abstract

Reinforced concrete bridges with different types of deck slab have been widely used for both road and railway bridges. The most common type is the slab deck used for short span bridges. For medium span in the ranges of 12 to 25 m T- Girder and slab deck is widely used. In the case of T Girder and deck slab type, the slab span in two directions since it is cast integrally with main girder and cross girder. The deck slab is generally designed for either by 70 R loading or class AA Tracked wheel loading. IRC recommends bridge designed for class AA loading should also be checked for IRC class A loading. However in conventional analysis many of the important considerations are ignored by the various designers, which proved out to be somewhat unrealistic during the pragmatic conditions. For an assessment of the load carrying capacity of a bridge, one needs to know the maximum bending moment and the shear force included in the beams or girders of the bridge by vehicular loads. These maximum design load effect can be calculated by the conventional method such as Courbon’s method. The main objective of study is to analyse super structure for IRC Class AA loading (Tracked vehicle) and IRC Class A loading to compute the values of bending moment, shear force and deflection for span range from 16 to 24 m. The analysis of super structure of different sections and spans is carried out by Courbon’s method using MS Excel and by using STAAD.pro software. The bending moment and shear force results obtained by STAAD.pro were less up to 18 m span when compared to results obtained by MS Excel and vice-versa as the span increased. The safe design section is obtained by deflection criteria.

Analysis and Design of Suspension Cable Bridge: A Review

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 1st March 2018

Nakul S. Nagose | RVRK Prasad

Abstract

A suspension bridge is a type of bridge where the deck is hung below the suspension cable in vertical suspenders. The main forces are tension in cable and compression in the towers. The cable is anchored at each end of the bridge to maintain tension in this cable. Single steel wires have a 2.54 mm thick can support over half a ton without breaking. The central sag of the cable is varies from 1/10 to 1/15 of the span. The main disadvantage of aerodynamic profile may be required to prevent the bridge deck vibrating under high wind. The suspension bridge is generally not used for heavy rail traffic where high concentrated live load occurs, which adds dangerous stress to the structure. In suspension cable bridge the types of load such as dead load, live load, wind load and design parameter are determined and analyzed by using software sap2000 for different condition. In the following paper same important papers are discussed below.

Analysis and Treatment of Oil Field Produced Waters of Upper Assam Basin

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 16th April 2018

Gogoi Tapan Jyoti | Gogoi Subrata Borgohain

Abstract

The largest volume in oil industries comprise of Produced Water (PW) from oil fields. The water besides containing hydrocarbons in soluble, emulsified and free form, also is high in suspended and dissolved solids. Hydrocarbons are considered among the most harmful pollutants as they are lethal to human, animal and plant on direct consumption. Therefore the PW samples have to be treated before discharging it into the environment as it contains harmful constituents. Results showed that the PW samples had water content above 80% along with Oil and Grease (O&G), salinity, turbidity, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Ca, Fe, Na, K, Li, Mg, Mn, Pb and Zn. However the presence of Cr, Cu, Mo, and Ni have not been observed in the samples. These samples were treated with microfiltration and ultrafiltration in the continuous cross-flow cell. Most of the results after the treatment processes were found to be within range as per Central Pollution Control Board (CPCB) of India. However, the result of dissolved oxygen while treating with microfiltration was not found to be within range. Also, the treatment of oil and grease by both the treatment processes did not meet the specified range set by the pollution control board of India. Therefore further filtration has to be done to bring all the parameters within range.

Analysis of Additive Manufactured Tibial Spacer Used In Total Knee Replacement Implant

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 7th February 2018

Devadath V R | Swathi Harish, Brijesh Kidiyoor

Abstract

There is a huge demand for biomedical implants in recent years, especially for Total Knee Replacement (TKR) implants. The complex geometries of patient-specific biomedical implants are tedious and time-consuming to fabricate using conventional manufacturing methods. Emerging technology like Additive Manufacturing (AM) has a wide scope by allowing complexity in geometry and a huge reduction in manufacturing times of these implants. In a total knee replacement of posterior cruciate-retaining type, the tibial spacer is one of the important components of the implant. In this research tibial spacer was fabricated by Fused Deposition Modeling (FDM) process using bio-compatible material Poly Carbonate-ISO (PC-ISO). The fabricated component tibial spacer made of PC-ISO was analysed for wear and strength, it was found that production time by AM technology is less when compared with the conventional processes, it also exhibited higher hardness and higher resistance than the most widely used material Ultra High Molecular Weight Poly Ethylene (UHMWPE). The experimental test results were within the limits as per medical journals. The surface roughness was also tested and found to be within the satisfactory range required for the knee mechanics.

Analysis of bubble deck slab using different materials

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 10th May 2018

Shreya Singh | Dr.(Prof.) Kailash Narayan

Abstract

Reinforced concrete slab is an essential component of the structure. Various parameters such as span, depth and reinforcement are designed as per standard codes. Due to large amount of concrete used to cast these slabs, dead weight also increases. Heavier structures are less desirable as compared to lighter structures as it involves larger costs, time and labour. An alternative to this type of conventional slab is a bubble deck slab which introduces bubbles made up of various materials which reduce the overall weight of the slab.

Abstract

Reinforced concrete slab is an essential component of the structure. Various parameters such as span, depth and reinforcement are designed as per standard codes. Due to large amount of concrete used to cast these slabs, dead weight also increases. Heavier structures are less desirable as compared to lighter structures as it involves larger costs, time and labour. An alternative to this type of conventional slab is a bubble deck slab which introduces bubbles made up of various materials which reduce the overall weight of the slab. Various studies have shown that the weight of the bubble deck slab reduces by approximately 35% as compared to the self weight of the conventional reinforced concrete slab. In this study conventional slab was compared with bubble deck slab made up of various materials using finite element analysis on ANSYS Workbench 14.0. Total deformation for conventional reinforced concrete slab and bubble slabs made up of glass reinforced polymer fibres, carbon reinforced polymer fibres and epoxy were analysed and compared. This study showed that different values of total deformation was obtained for bubble deck made up of materials like carbon reinforced polymer fibres, glass reinforced polymer fibres, epoxy and conventional reinforced concrete slab.

Abstract

Regions prone to seismic disturbances are designed in such a way that its stiffness should be maintained during moderate earthquakes and it should absorb and it should dissipate a large amount of the energy during severe earthquakes. The conventional framing system required heavy sections to fulfilthe stiffness criteria and ductile capacity. the concentrically braced frames show good results in stiffness but poor results in ductility hence resulting in bad energy dissipation. The current study deals with the eccentrically Braced Steel Frames (EBF). EBF configuration is similar to conventional braced frames with the exception that one of the ends must be connected eccentrically to the frame. The energy dissipation is achieved through the yielding of a beam segment known as the link. EBF is economical and satisfies both the stiffness as well as the ductility requirement. In the present study eccentrically, braced steel frames are used with increasing link of 0 mm, 500 mm, 1000 mm and 2000 mm. The building is a 21-story building with bracings provided at the corners. Various parameters such as Maximum story drift, Stiffness, Torsion, Natural time period are calculated for each floor using ETABS.

Abstract

Aqueduct is a watercourse constructed to convey water over an obstacle, such as natural streams, valley etc. In modern days, the aqueduct is also used for any system of pipe, ditches, canal, tunnels, and bridges which is used as an artificial watercourse. If the structure is constructed in the earthquake-prone area dynamic analysis of structure is necessary. The structure is analyzed by considering pressure effects of fluid, but for special structure simple and yet accurate model for dynamic analysis is needed. To find out fairly accurate results, numerical modeling of water and dynamic analysis is necessary to perform. In this paper, seismic response analysis of a proposed aqueduct in the Pune seismic zone will be performed. Particular effort is devoted to finding a suitable numerical model that can accurately represent the proposed aqueduct design, water-structure interaction, and the effects of bearing properties of the aqueduct on its responses to seismic ground excitation. The result shows that using rigid bearing in the analysis can significantly reduce the aqueduct responses as compared to the bearing pads simulated by elastic link supported aqueduct.

Vishnu | Mubarak A. K.

Abstract

The shock formation in rocket engine nozzles have been a significant area of study for researchers. The oblique shock formation has an adverse effect on the efficiency of nozzles. Here a CFD analysis of three contour nozzles with change in divergence angle was conducted using ANSYS Fluent. Supersonic jets emanating from a chocked, axisymmetric nozzle at different pressure ratios are analyzed here. The variation of shock structure with change in divergence angle is studied. While varying the geometry the length and area ratio of nozzles was kept constant. Care was taken to keep the nozzle exit angle zero degree. No shock free condition was observed even at design Mach number of M=1.5. Simulation has been done on a clear conical nozzle of divergence angle of 2.950, contour nozzles of divergence angles 40 and 50 respectively. The increase in divergence has shown considerable effect in flow properties. The pressure variation along center line was low for high divergence angle. The better design among the three was analyzed by comparing the static pressure, Mach number and density variation along the center line. These flow parameters were compared for two different pressure ratios. The contour nozzle with divergence angle 50 was found to be the best among the three in design. The axial velocity at the exit was compared among them the nozzle with highest divergence angle had higher axial velocity at exit, so it was inferred that the thrust exerted on the walls was higher. By analyzing the flow characteristics the nozzle with high divergence angle showed improved results.

Abstract

Recent Studies suggest that 40 percent of the energy is consumed by buildings during their operational phase alone and one of its major consumer is the HVAC system. This energy can either be traced back to a conventional source or a nonconventional source, but because HVAC system is a specific energy consumer in a building, powering it with a renewable source may be a tight call, thus resorting us to use only conventional source of energy; because pollution too is the problem that we have to consider the optimization of energy usage is of prime importance and that is where the building envelope comes into play. The main objective of this paper is to analyze the effect on cooling and heating system in a building by considering various glazing technology in windows which form a major part of building envelope. For this analysis, Casanova 3.3 software has been used and the building has been assumed to be situated in New Delhi, India.

Analysis of High Rise Buildings with Viscoelastic Dampers

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd March 2018

Saurabh V. Tadas | S. V. Bakre

Abstract

Structures constructed now days are high rise R/C structures, which have very less lateral load carrying capacity due to earthquake and wind loads. The reason behind this is structure cannot dissipate earthquake energy by its inherent damping alone, therefore various seismic response control system for structures are developed. In such control systems, the supplementary damping device is incorporated within the structure, these damping devices are active, passive, semi-active or hybrid types. In this paper feasibility of using viscoelastic dampers to reduce the effect of the earthquake on high rise buildings is studied. Viscoelastic dampers dissipate buildings mechanical energy by converting it into heat. Analytical study of 12 storey R/C office building for finding out response reduction due to viscoelastic dampers is carried out. A non-linear time history analysis is carried out for building with viscoelastic dampers and without dampers and responses are compared. Top story displacements, velocity, acceleration and base shear is studied for building with damper and without a damper.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 23rd August 2017

M.P. Jenarthanan | KalyanKiranChippada, Nikhil Raghavan Guduri

Abstract

This study aims to develop a mathematical model for analyzing the surface roughness and delamination factor and to infer the influence of the individual input machining parameters (cutting speed, depth of cut and feed rate) on the responses in milling of Sheet Metal Composite (SMC) with solid carbide end mill cutter coated with PCD using Taguchi methodology. In Taguchi methodology, three factors and two responses were employed to carry out the experimental investigation. Multiple Regression Analysis from “Minitab” software was used for regression and graphical analysis of the data were collected. The optimum values of the selected variables were obtained by solving the regression equation. Analysis of variance (ANOVA) was applied to check the validity of the model and for finding the significant parameters. It is seen that Feed rate is the most influencing factor in affecting the surface roughness and delamination. In SMC composite as the speed and feed increases the surface roughness value decreases. Moderate feed and speed gives ideal finish. But the parameter depth of cut shows a wavy nature. Only for a very high depth, the roughness increases. The optimized values of the machining parameters were used to calculate the surface roughness and delamination factor of the machined surfaces, with the chosen range resulting with 93 per cent.

Abstract

Aluminum 7075 alloys have been proposed for extensive use in automotive engine applications and there have been discrete cases of experimental implementation. In order to enhance the usability of this material, it has been investigated in composite forms with various ceramic reinforcements. Viability of the different constituents depends on the compatibility of their physical and chemical properties. The service conditions are characterized by extreme stress and temperature conditions very close to failure. Hence thermal stresses play an important role in success of these materials. In this present investigation efforts are made to study the mechanical properties of as cast and heat treatment aluminium nitride particulates reinforced Al7075 composites, containing aluminium nitride particulate of 2-3 microns in different compositions. The vortex method of stir casting was employed, in which the reinforcements were introduced into the vortex created by the molten metal by means of mechanical stirrer. Castings were machined to the ASTM standards on a highly sophisticated lathe. The degree of improvement of mechanical properties of MMCs is strongly depending on percentage composition of aluminium nitride particulate reinforcements. An improved mechanical properties are occurs on reinforced compared to unreinforced MMCs

Application of AE Based Mathematical Procedure for Identification of Corrosion in Reinforced Concrete Element

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 28th February 2018

Nayantara Prakash Ghodake | 

Abstract

Corrosion is a major cause of degradation of reinforced concrete (RC) structures. Corrosion of steel rebar in concrete is an electrochemical process and it has been widely studied using various non-destructive techniques such as Half-cell potential, linear polarization resistance, electrochemical impedance spectroscopy etc. All these techniques cannot be called truly non-destructive technique as the instruments require physical and electrical contact with steel embedded in concrete. To overcome this difficulty, the research for finding the applicability of other non-destructive techniques such as ultrasonic pulse velocity, acoustic emission (AE) technique etc. for quantification of corrosion is going on. From the literature, it is found that AE technique is a powerful technique for identification as well as quantification of corrosion without having any physical or electrical contact with the reinforced steel. For corrosion quantification AE based mathematical model has been developed which can quantify the corrosion in small-scale cylindrical RC specimens. Thus for commercial use of the developed mathematical model, it is necessary to check its applicability for the changed geometry of specimens. The present paper focuses on checking the applicability of developed mathematical model for a rectangular geometry of specimens. For the experimental work, RC slabs of dimensions 500 mm x 300 mm x 60 mm with single reinforcing steel bar were cast and subjected to accelerated corrosion. From the experimental results, it was found that the predicted mass loss values of corroded rebar using developed mathematical model are in agreement with that of the actual mass loss which indicated that AE based mathematical model can be successfully used for rectangular specimens

Abstract

Road Transport is a critical infrastructure for economic development of a country. It influences the pace, structure and pattern of development. The capacity of National Highways in term of handling traffic (passenger and goods) needs to be in keeping pace with the industrial growth. India is having one of the largest road networks of over 46.99 lakh km. It comprises National Highways, Expressways, State Highways, Major District Roads, Other District Roads and Village Roads. A growing demand for passenger and public transport have led to a significant increase in air pollution and greenhouse gas (GHG) emissions. A study conducted by the Central Pollution Control Board (New Delhi, India) in six cities – Delhi, Kanpur, Bangalore, Pune, Chennai, and Mumbai, concluded that the transport sector contributes to more than 30 percent of the ambient air quality in these cities – either directly from the vehicle exhaust or indirectly via the re-suspension of dust on roads due to vehicular movement. The health impacts of air pollution from the transportation sector are significant – and the nature of the issue is that those areas with the most population density are most affected. The government has taken many initiatives for green highways. By using a live case study project we have implemented a credit system for Green Highway system.

The Polypropylene fibre reinforced concrete (PPFRC) contains very short discrete Polypropylene fibres which act as an internal reinforcement so as to enhance the properties of the concrete. Addition of discrete fibres into a cement mix reduces the cracking in elastic range, increases tensile strength, deformation capacity and toughness of the composite. These properties of PPFRC primarily depend upon length and volume of propylene fibres (PPF) used in the concrete mixture. In India the polypropylene fibre reinforced concrete has limited applications in several structures. The applications are mainly to inhibit the cracking. However due to the lack of awareness, proper design guidelines specifications, its uses are very limited. Therefore there is a need to upgrade information on the properties of Polypropylene Fibre Reinforced Concrete (PPFRC). For the study, polypropylene fibres of lengths 6 mm with 0.1 %, 0.2%, 0.5 %, 1%, 1.25%, 1.5% and 2% volume fractions are used. The result reported includes an experimental investigation for measurement of workability of PPFRC using standard test method and a selected mechanical property of PPFRC to study the effect of volume fraction of (PPF) for predicting PPFRC in compression

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd March 2018

Surbhi Ambarkhane | Dr. Nina Dhamge

Abstract

For the seismic design of building structure, the traditional method, i.e., strengthening the stiffness, strength, and ductility of the structure has been in common use for a long time. Therefore, the dimensions of structural members and the consumption of material are expected to be increased, which leads to higher cost of the buildings as well as larger seismic responses due to the larger stiffness of the structures Thus, the efficiency of the traditional method is constrained. To overcome these disadvantages associated with the traditional method, many vibration-control measures, called structural control, have been studied and remarkable advances in this respect have been made over recent years. Structural Control is a diverse field of study. Controlling the response of the structure is one important aim of researcher these days. Dampers are one of the popular vibration control devices of structures, because of their safe, effective and economical design. This paper presents an overview of literature related to the behavior of different dampers in the seismic event. The review includes different types of dampers like the metallic damper, viscous damper visco-elastic damper, and friction damper.

Apply of Hydro Forming For Futuristic Manufacturing

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 19th March 2018

Seshabattar Phaneendra | Vuppala Balu

Abstract

A hydrofoil is a foil which operates in water. As a hydrofoil-equipped watercraft increases in speed, the hydrofoil elements below the hull(s) develop enough lift to raise the hull up and out of the water. This results in a great reduction in hull drag, and a further corresponding increase in speed and efficiency in operation in terms of fuel consumption. The foil is shaped to move smoothly through the water causing the flow to be deflected downward which according to Newton's Third Law of Motion exerts an upward force on the foil. This turning of the water causes higher pressure on the bottom and reduced pressure on the top of the foil. This pressure difference is accompanied by a velocity difference, via Bernoulli's principle, so the resulting flow field about the foil has a higher average velocity on one side than the other.

Abstract

In present years, water pollution has become one of the most critical environmental challenges. The Artificial Floating Islands (AFIs) are an innovative variant of wetlands with substrates-rooted plants and free-floating aquatic plant systems, which consist of aquatic or terrestrial plants growing in a hydroponic manner with buoyant frames floating on the surface of water bodies. Eco engineered remedy such as floating wetland is commonly presented as an important strategy for maintaining and improving water quality and aesthetic appearance of water bodies. Literature review indicates that previous works are carried out at different scales using different design parameters. Artificial Floating Islands (AFIs) are vegetated floating platforms applied in lakes, ponds and reservoirs to improve the aquatic environment. AFIs have four functions: water purification, habitat enhancement shoreline erosion protection, and improved landscape features. This paper reviews the studies carried out by earlier researchers on AFI. The primary advantages of AFIs are that they float and adjust to water level variations in reservoirs and reduce predation risks by providing safe protections for nesting birds. The paper presents the type, structure, function, and developing history of AFIs. By analyzing the social-economic benefits, advices are given for applying AFIs technology to improve the water environment and to improve crops thereby creating a win-win model for both environmental protection and agricultural development in rural places. Based on the review it can be concluded that AFI technology is promising and acceptable even indigenously

Abstract

Artificial intelligence is a theory. The base object is the agent who is the "actor". It is realized in software. Robots are manufactured as hardware. The connection between those two is that the control of the robot is a software agent that reads data from the sensors decides what to do next and then directs the effectors to act in the physical world. The aim of this paper is to provide basic, information of global scope on two emerging technologies: artificial intelligence (AI) and robotics. According to the Department of Trade and Industry (DTI), it is important to consider these emerging technologies now because their emergence on the market is anticipated to ‘affect almost every aspect of our lives’ during the coming decades(DTI,2002).Thus, a first major feature of these two disciplines is product diversity. In addition, it is possible to characterize them as disruptive, enabling and interdisciplinary.

Leena Prasad Aphale | Swapna Ashok Dhavale, Prasad Arun Aphale

Abstract

Structural health monitoring is a technical process which has been activated or treated at post-construction level by the expertise and structural auditor. A lot of emphases has been given for the post-construction structural health monitoring techniques, but ‘Pre-construction’ and ‘During construction’ stage of a structure are also equally important so that minimum requirement of the process and best quality assurance will be achieved to make the project economically sustainable over a long period. While thinking for the above mentioned new aspect of health improvement, majorly three early stages are to be taken into consideration as- Architectural design and planning, structural and RCC design, and construction stage which make a ‘golden triangle’ where the major role of Architect, Structural engineer and the contractor is defined. This paper is a sincere effort to discuss and application of health improvement and monitoring aspects during pre-construction stage and ongoing construction process with the examples and remedial solutions.

Assessment of Recycled Concrete Aggregate Usage in Concrete

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 10th January 2018

Tresor Ntaryamiraa | Anthony Quansaha, Yunlian Zhanga

Abstract

Recycling concrete is a significant step towards eco-friendly construction practices. The use of recycled concrete aggregates in new structures provides a sustainable development. Initially, recycling of demolition waste was first carried out after the Second World War in Germany and henceforth, there has been a reduction in the quantity of construction and demolition waste; and at the same time, it lessened the depletion of natural resources by providing an alternative. There have been recorded cases of application of recycled aggregate(RA) in a large number of construction projects of many European, American, Russian and Asian countries. The test results of ductility and the stiffness of beams with RA are equal or higher than those with natural aggregate. However, concrete made with recycled concrete aggregates exhibits different engineering properties. This difference is mainly due to the attached mortar paste on recycled concrete particles. Recycled aggregates have been found to have high water absorption capacity, which affects various properties mainly mechanical performance of the resulting concrete mix. Based on previous research, this paper presents a comprehensive overview of the recycled concrete material characteristics and the effect of using the recycled concrete material on the mechanical properties, the durability properties and structural performance of concrete so as to help relevant units and staffs in the practical work.

Vikas V.Mehetre | V.T.More

Abstract

Today many high rise building adopted floating column for parking, assembly hall purposes. The load of floating column is a point load which is taken by transfer girder. These type of structure are danger in highly earthquake prone area because storey shear from all higher floor are not transfer to ground due to this discontinuity. This type of structure also called as stiffness irregularity. Shear wall is use in high rise structure to resist earthquake load and other lateral loads such as wind load. In particular structure floating column & shear wall used combine. For this type of structure we don’t know best position of shear wall to reduce structural response of transfer girder. To find out best position of shear wall we analyze several model such as 10,15,20,25,30 storey with different shear wall locations and compare structural responses of transfer girder by conventional, construction stage analysis with EQ zone-IV and wind analysis with wind speed 47m/s in the form of bending moments, shear force and displacement with the help of ETABS V 2015

Abstract

Biofuel – An alternative source of energy for present and future.In the present scenario, there is a huge demand for various oils and their high prices is an apprehension for the mankind. Since there is an increased awareness of the eco-friendly issue, there is an urgent need to explore the alternative energy sources. Various alternative energy sources like nuclear power, solar, wind, biofuels are well known, where biofuel sounds like one of them in terms of usage and the production process.Biofuel is the process where the energy of organic materials (Renewable biomass) is replaced with a function of fossil fuels. Processes like trans-esterification which converts animal and vegetable oils into usable fuel forms. From different sources, algae produce a large amount of energy. Algae represent the significant group of biological systems, where few of them are known to produce vast quantities of lipids relative to their total biomass. However, it is important to note that the technology has so far not been sufficiently developed to allow these biofuels to be produced commercially. Economics is playing a crucial role in ensuring a smooth transition to a Biofuel future.

Bladeless Turbines

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 17th August 2017

Yashwant Hardikar | Durga P. Ghatge, Gaurav N. Devdikar

Abstract

Turbine that would provide a quite safe, simple andefficient alternative to our supposedly Bladed Turbine engine is the need of the hour. Bladeless WindPower Generation uses a radically new approach to capturing wind energy. The device captures theenergy of vorticity, an aerodynamic effect that has plagued structural engineers and architects for ages (vortex shedding effect). As the wind bypasses a fixed structure, its flow changes and generates a cyclical pattern of vortices. Once these forces are strong enough, the fixed structure starts oscillating. Instead of avoiding these aerodynamic instabilities the design maximizes the resulting oscillation and captures that energy. Naturally, the design of such device is completely different from a traditional turbine. This technology of the Bladeless Turbines puts it at a very low range of capital intensity. It also makes it highly competitive not only against generations of alternative or renewable energy, but even compared to conventional technologies. Bladeless turbines are also thereenest turbines with almost nil harmful effects on the environment. The bladeless turbine has a promisingfuture as a new power generation system.

Blast Load Resistance of Cold-Formed Steel Hollow and Infilled Column

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 21st April 2018

Pooja Gadekar | Divya Joshy, M.Helen Santhi

Abstract

Cold Formed Steel Tube (CFST) members are commonly used as columns in the construction of low to medium height industrial and domestic buildings. Their structural behaviour is enhanced by filling the tubes with concrete and other materials. The infilled members are superior to the hollow members in resisting axial and lateral loads due to the composite action. An attempt has been made in this paper to analyse the cold formed steel short hollow and infilled column of dimension 150mm x150mm x 5mm with column height 1.5m subjected to blast loading at the standoff distances of 0.5m,1m,1.5m respectively using the software LSDYNA. The grade of concrete used as infill is M30 grade. The intensity of blast remains constant and the blast load is applied at ground and mid-height of columns. Strain and stress levels are higher in hollow column than that of infilled column. The deflection is found to be less in infilled column

Blast Resistance Analysis of Door Panel

Thimmesh. T | M. D. Goel

Abstract

During earlier days, not much importance was given to the blast resistance design of doors in blast resistant design of structures. Later on, due to large numbers of deaths because of failure of doors, high priority was given to the blast resistant design of doors. In earlier cases, doors were traditionally designed using huge solid materials to resist the blast load. The use of traditional design results in increased material quantity and cost of construction. Recent technological advancement lead to use of engineered materials wherein use of reserved material strength was made to resist blast loading. The blast load is the load with high energy and higher frequency, thus need special attention for analysis and design of structural components. The present study deals with the different doors configurations wherein effect of stiffness, natural frequency and mass of the door is investigated. Finite Element (FE) analysis is carried out to study the dynamic response of door under a given blast loading using ABAQUS®. In the present investigation, tempered AISI 1045 steel is used as door material. Modal analysis is carried out to obtain modal frequency of different door configurations considered in the present investigation wherein mass of all the doors are kept almost constant. Herein, blast loading from 5 kg TNT at a standoff distance of 1 m is applied to the door to understand their dynamic response. The peak displacement of door at different locations has been computed to understand their failure pattern. From the results, it is observed that displacement is significantly reduced just by changing the geometry of door with other parameters being same

Buckling Analysis of Non-Prismatic Column

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 26th February 2018

Adesh Singh | M. D. Goel

Abstract

The constraints on the construction of various irregular shape are reduced remarkably with the advancement in manufacturing processes. The precise variation in the shape of the structure, in the form of any mathematical function, along the length is possible and can be achieved with help of three-dimensional printing technique. If 3-D printing technique is implemented to produce structural member, higher specific strength and stiffness can be achieved, with the same volume of material, by varying material distribution along the length of the member. In view of this, an attempt is made herein to investigate the critical load of a solid column due to the variation of shape in terms of a mathematical function. The present investigation is limited to the computation and comparison of critical buckling load of the solid clamped-pinned column with a linear, trigonometric and exponential variation of shape along the length by employing commercially available FE package ABAQUS®. Detailed FE analysis is carried out and results are compared and discussed for assumed variation

Punitha.M | Rajendran.R

Abstract

Bypass flow is rapid downward movement of water and solutes beyond the root zone of the crop along with air-filled of the cracked soils. Paddy field is generally subjected to many cycles of alternative flooding and drying condition (AFD) during rice growing period. This alternate condition cycles can create a large variation in soil structure that subsequently affects soil water and nutrient retention and migration. Bypass flow processes were studied in a cracked, previously puddle rice soil. Vertical continuity of soil cracks 12 mm in width was determined in the field using a morphological staining technique. An infiltration experiment showed that water was mainly absorbed in the subsoil between 0.3 and 0.6 m depth. This study aimed to investigate the soil shrinkage behavior, cracked surface area and its consequences on water percolation in paddy fields under AFD.

Abstract

Blood flow is the topic of interest for mankind from the ancient time because of its usefulness. Blood is a very complex fluid which is nonhomogeneous and non-Newtonian in nature. Blood flows in the body with pulsating nature. Study of blood flow can be very helpful to improve the understanding of human body. Due to such complex nature, it is very hard to study the blood flow in by experimental analysis, but with the help of CFD, it is possible.

Akash Chavda | Atal Harichandan

Abstract

Three reactor chemical looping reforming system is used for hydrogen production by capturing the harmful gases like CO2, NOx and SOx using a metal oxide as an oxygen carrier and steam. We investigate the bubble hydrodynamics and flow physics by the use of Ansys FLUENT which is based on finite volume approach. The numerical model of the steam reactor is also developed to understand chemical kinetics between gas-solid phases based on kinetic theory of granular flow. A Eulerian multiphase model has been used to describe the continuum principle of two-fluid models for both gas and solid phase. In the present work, steam and iron oxide is used as fuel and oxygen carrier respectively. The numerical results are validated with the experimental and numerical results available in open literature. The simulation is found to capture the bubble hydrodynamics in terms of bubble generation, rise, growth and rapture in the unsteady and steady-states in a better manner. Numerical simulations are carried out to capture the bubble hydrodynamics and the relationship between the molar fraction of products and gas phase and bubble formation. Solid volume fraction contour is used to understand the better flow physics and chemical kinetics.

Umesh Kulkarni | A. K. Gangrade, Ravindra Shende

Abstract

This paper explains the amount of thrust vectoring obtained using jet type of Thrust Vectoring Control (TVC) system. A new thrust vectoring component is suggested and validated with available experimental data. The methodology entails the design of three dimensional nozzle using two input design parameters followed by descretisation of control volume and simulation through ZNPL PUNS solver. Grid independence test was carried out for basic nozzle case (nozzle with no TVC component). Taguchi design technique for design optimization was adopted. Nine cases were simulated for varying position of TVC component in a direction normal to nozzle axis i.e. nozzle exit blockage along with clearance between TVC component and nozzle exit plane along the axis downstream. The optimised cases were selected through post processing and analysing the solution in perspective of nozzle wall pressure forces and TVC efficiency parameters.

CFD Analysis of the Effect of Material Properties of Nose Cone on the Heat Flux and Thermal Field during Re-entry of Space Vehicle

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 23rd November 2017

K.V.Sreenivas Rao | Sujan.P, Sachin H.S

Abstract

Safe re-entry of the spacecraft is one of the biggest challenges for the space engineers. Overheating of the surface of spacecraft is a major concern. A space vehicle re-entering the atmosphere must pass through Earth’s dense fluid medium at extremely high speeds. It results in the generation of a shock wave in front of the re-entering space vehicle. As the shock waves slam into the air molecules in front of the re-entering space vehicle, they go from cool, dormant state to an excited state, acquiring heat energy, which transfers to the metal object in contact. This results in the generation of very high temperatures i.e. up to 30000C. Surviving this temperature is impossible for conventional metals. So, composite materials are used in most parts of thermal protection system of a space vehicle. In this present work, CFD analysis using SolidWorks Flow Simulation software is made on the surface contour of the nose cone for three different materials. Heat flux and temperature generated on the surface of nose cone is compared to the three materials. Heat flux obtained from the CFD analysis is used to calculate the temperature that is transferred inside the crew cabin. From the analysis, we can conclude that Reinforced Carbon-Carbon is best suitable for nose cone of the space vehicle.

Abstract

There has been a serious demand for intermittent movement of packages in the industries right from the start. Though the continuous movement is more or less important in the same field the sporadic motion has become essential .The objective of our project is to produce a mechanism that delivers this stop and move motion using simple four-bar mechanism. The advantage of our system over the conveyor system is that the system has a time delay between moving packages and this delay can be used to introduce any alterations in the package or move the package for any other purpose and likewise. While in conveyor system such actions cannot be performed unless programmed module is used to produce intermittent stopping of the belt which basically is costly. The prototype design requires electric motor, shafts and the frame of which the frame and platform on which the packages are moved is fabricated. All the links are being made of Aluminum which reduces the weight of the whole system including the head which has a direct contact with the boxes being moved. The system is expected to move as heavy packages as 2 ------3kgs approximately

H P Raju | Shreeraj B N, Murali Krishna N L

Abstract

Extrusion honing (EH) process is employed to deburr, polish or radius surfaces and edges by flowing a silicone abrasive medium over the surface to be finished. Such finishing operations play a vital role in producing method of machine components. EH could be a time consuming process, even though EH is employed within the industries particularly in the case of finishing complicated internal and external shapes. In EH process, medium is the key elements that control the finishing process. Though, commercially available abrasive medium are very expensive and its affordability is an issue, especially for price sensitive industries. Inconel (718) material is widely used in aerospace industries, hence it has been chosen for the characteristics study through EH process. In the present study silicone and silicon carbide abrasive is chosen as the medium. Surface roughness parameters are used as a means of determining the performance of the EH process. The main experimental parameters are the abrasive concentration, number of passes and keeping constant hydraulic pressure. It is observed that the roughness parameters Ra, Rz, Rt and Rpk decreases after 15 passes and 25% of volume fraction of abrasive concentrations were used for the experimentation.

Abstract

In the present work Neem oil is used as a hotspot for biodiesel generation by means of base catalyzed transesterification and biodiesel created all the while is joined with an added substance (Dimethyl Carbonate) in shifting volume extents to make a bit of test energizes for engine application. Analyses were run out on a diesel motor under differing loading condition to examine around the performance and emission qualities of the motor fuelled with the present test fuels. The aftereffects of examination show an increment in brake power and brake warm effectiveness with burden for all test powers. It is likewise noted that the brake warm effectiveness picks up with the rate of added substances in the test bombs. The brake particular fuel utilization diminishes with increment in added substance rate in the test bombs. The exhaust gas temperature increments practically directly with burden for all test powers and abatements with an increment in added substance rate in the fuel. Results demonstrate that the CO and HC outflows have a tendency to decrease with the increment in the added substance rate in biodiesel. The smoke and NOx outflows additionally diminish with increment in added substance rate in the biodiesel fuel.

Characterization of Cryogenic Globe valve for advanced launch Vehicles

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 4th January 2018

N Sreekanth | R.Anand

Abstract

Liquid Propellant servicing of any propulsion systems is very critical due to hazardous nature of fluids and safety involved in handling. For any successful launch mission, fluid servicing, especially with respect to cryogenic servicing is very critical due to complex preparation, chilling, filling, and pre-launch operations involved. During fluid servicing of launch vehicles, critical process parameters such as pressure, temperature and flow rate are required to be attained within the specified tolerance limits to meet launch lift-off requirements. Cryogenic propellants have a very low boiling point and low latent heat of evaporation due to which pressure and flow control is very challenging. Hence, it is very important to predict the actual performance characteristics of the flow control valve for different stroke lengths and for different plug profiles and select the optimum plug to suit to process conditions. Flow coefficient Cv is of primary interest in predicting the valve performance during its operation. This paper attempts to predict performance characteristics of a cryogenic globe valve used for flow control of Liquid Oxygen flow using computational fluid dynamics (CFD). Valves having different valve capacity factors were considered for evaluation of performance characteristics and derived the pressure and velocity contours inside the valve. The performance of this control valve installed in the Cryogenic fluid circuits have been independently evaluated for various process flow conditions and suitability of the valve has been verified for optimum flow conditions. The results of the computational analysis are found to be in close agreement with experimental tests.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Sanjay B Borghate | Dr R. K. Ingle

Abstract

In construction of a multi-storey building while assessing the structural cost, it is evident that the bulk of the expenses is utilised for the floor slab construction. Hence the overall budget of a structure depends on the efficiency and expenditure of the floor slab system. Efficacy of the design and structural layout depends upon the quality of the material used, where as the actual cost of the structure may depends on factors such as speed of construction, availability of labour, competitive tendering, local market conditions, and equipment and cost of construction finance. Choice of the floor is very important for a building to meet the needs of major financial occupiers in today’s market. In this paper, the different types of RC slab floor systems and their advantages and disadvantages are discussed.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Dr.K.Thirupathi Reddy | Dr.M.L.S Deva Kumar,Mr.Ch.Ravi Kiran

Abstract

Using renewable oxygenated fuels such as ethanol is a proposed method to reduce diesel engine emission. Ethanol has lower density, viscosity, cetane number and calorific value than petroleum diesel (PD). Microalgae oil is renewable, environmentally friendly and has the potential to replace petroleum diesel. In this paper, microalgae oil (10%) and ethanol (10%) have been mixed and added to (80%) diesel fuel as a renewable source of oxygenated fuel. The mixture of microalgae oil, ethanol and petroleum diesel (MOE20%) has been found to be homogenous and stable without using surfactant. The presence of microalgae oil improved the ethanol fuel demerits such as low density and viscosity. The transesterification process was not required for oil viscosity reduction due to the presence of ethanol. The MOE20% fuel has been tested in a Variable Compression Ratio Research Engine at different speed. The engine test results with MOE20% showed a very comparable engine performance of in-cylinder pressure, brake power, torque and brake specific fuel consumption (BSFC) to that of petroleum diesel. The NOx emission and HC have been improved while CO and CO2 were found to be lower than those from petroleum diesel at low engine speed.

Abstract

In recent times, understanding the vibration patterns of structures has become very crucial :courtesy the various types of forces, both static and dynamic coming into play. Modal analysis helps to determine the vibrational characteristics of a structure explicitly during its design process. Behavioral tendencies of structures under time dependant loads can at times be tricky as the exact nature of dynamic loadings is difficult to comprehend. Modal analysis has proven to be helpful in our understanding towards many vibrational phenomena that were encountered in practice. In this work, focus has been laid on one structural entity- the beam. Finite elemental analysis was carried out for the beams using ANSYS WORKBENCH as a platform for the same. Simply supported beams made up of structural steel, Carbon Fiber Reinforced Polymer(CFRP) and Glass Fiber Reinforced Polymer(GFRP) with both fibers aligned at zero degree inclinations were fabricated under ANSYS Workbench platform simulated under modal analysis. Results were duly compared with respect to the natural frequencies and deflections produced in the three types of beams.

Abstract

Steel-concrete composite construction has gained large acceptance all over the world as a substitute for pure steel and pure concrete construction. However, this approach is a new concept in the construction industry. In this work we are creating the steel-concrete composite (G+10) frame using ETABS as an EIS-RC (encase I section column with RC beam), EIS-SB (encased I section with steel beam), CFT-RC (concrete filled square tube with RC beam), CFT-SB (concrete filled square tube with steel beam), CIS-SB (confined I section with steel beam), CIS-SB (confined I section with steel beam) and RCC frame. Static nonlinear pushover analysis is used for comparison of structures with the help of ETABS 2015 software. The majority of building frames are designed and constructed in reinforced concrete structures, depending upon the availability of constituent materials and the workmanship required in construction industry along with practicality of the existing design codes. Now a day to fulfill the demand of increasing population there is need of high rise building construction and today in India RC construction is popular to fulfill the demand of the construction industry

Abstract

The effects of Benzofuran-2-carboxylic acid (BF) & Amla (Emblica officinal is) leaves aqueous extract as a corrosion inhibitor, behaviour of mild steel has been investigated in hydrochloric acid solutions containing Experiments were performed by weight loss method for different time intervals and at room temperature. The inhibition efficiency of Benzofuran-2-carboxylic acid was found to increase with inhibitor concentration and also in the presence of sodium bromide and sodium iodide. Inhibition efficiency was found to increase with increasing concentration of inhibitor (0.2 g /l to 10 g/l) for 6 hours at room temperature. The maximum inhibition efficiency of Emblica officinal is leaving 87 % in 1 N Hydrochloric acid. From the comparative studies, it was investigated that the corrosion inhibition efficiency of Emblica officinal is leaves aqueous extract is approximately equal to that of Benzofuran-2-carboxylic acid in hydrochloric acid. This may be due to the presence of wide variety of compounds like tannins, alkaloids and phenols in Emblica officinal is a plant. The adsorption process was found to obey the Langmuir adsorption isotherm.

Comparative Study of Bubble Deck Slab Using Different Materials

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 11th June 2018

Shreya Singh | Dr. Kailash Narayan

Abstract

Slab is one of the largest structural members which consume structural concrete. The slab of greater thickness should be provided in the building if span of the slab is more or it is subjected to larger loads. Due to greater thickness of the slab, more amount of concrete and steel are being used and this leads to the increase in its self weight. To overcome this problem several researches are being conducted which results into the construction of slab of less weight that is elimination of excess concrete from the slab which is of no use. Therefore this leads to the construction of bubble deck slab. This paper deals with the analysis of bubble deck slab in which bubbles are made up of different materials which are high density poly ethylene and high density polypropylene and then comparing them with the reinforced concrete conventional slab using finite element analysis on ANSYS Workbench 14.0. Total deformation was calculated for the bubble slab made of high density poly ethylene, high density poly propylene and epoxy and for the conventional slab. Also the percentage reduction is calculated for the slabs and then these data were compared. The primary objective of this work is to compare the structural performance of the bubble deck slab with the reinforced concrete slab.

Comparative Study of Codal Provisions for Dynamic Wind Response of Tall Buildings

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd March 2018

T.J.Nikose | Dr. R. S. Sonparote

Abstract

Wind engineering is an up growing field in structural engineering. It is necessary for us to study it especially for Tall buildings that are prone to wind-induced oscillations. In the recent times, there have been so many catastrophic damages caused by high wind speeds especially in the United States and in the coastal regions of India. This proves that many buildings that are currently in use may not fully wind resistant. The Indian code of practice for wind load on buildings and structures (IS-875 Part-3 1987) included a procedure to determine along wind response of tall structures, while the across wind response and interference effect is not included in the same code. The present Indian specification ie IS 875 (Part -3):2015 included the specification for determining the along as well as across wind response. IS 875 (Part -3): 2015 included a mathematical expression for different parameters such as terrain factor, background factor, upwind velocity fluctuation etc. This paper includes a comparison of IS 875 (Part-3):1987, IS 875 (Part-3):2015 and AS/NZS:1170 (Part 2):2011 for dynamic wind response of tall buildings/structures. The comparison is validated by analyzing tall building for all-terrain categories as per earlier & previous version of Indian specification and with Australian codal provision for wind loading.

E. Sivakumari | S. Nishanthi

Abstract

Nickel base super alloy has the combined property of “high mechanical strength” and “High heat and corrosion resistance” at elevated temperature. This is the reason for which Nickel based super alloy are extremely used in Aircraft, Aerospace, Submarine and chemical industries. Machining of Nimonic C-263 has always been a challenging task owing to its hot strength, low thermal conductivity, tendency to work harden and affinity towards tool materials. Although coated tools have been used to overcome some of these challenges, selection of coated tool with appropriate deposition technique is of immense significance. The current study attempts to comparatively evaluate various performance parameters in machining of Nimonic C- 263 such as surface roughness, cutting force, tool temperature and tool wear. The tool materials used for this study are cubic boron nitride(CBN), ceramic and PVD coated TiAlN. To determine the effects of parameters selection on machining using Design of Experiments (DOE), Taguchi. L9 / L27 orthogonal array design of experiments was adopted to optimize the parameters. By using Taguchi and Grey Relational Analysis / Analysis of Variance (ANOVA) etc., an optimum value or the best value of surface roughness, cutting force, tool temperature and tool wear is obtained.

Comparative Study on Effect of Basalt and Glass Fiber on Workability and Compressive Strength of Microbial Concrete

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 28th December 2017

Kunamineni Vijay | Meena Murmu

Abstract

Basalt fibre (BF) is a novel sort of inorganic fibre which is produced from the expulsion of liquefied basalt shake and is industrially accessible. This investigation relatively examines the use of basalt and glass strands as fibre support in concrete. This paper also gives a concise portrayal of impact basalt and glass fibre on workability and compressive strength of microbial concrete. The fibres were added in concrete randomly by (0.25%, 0.5%, and 0.75%) of the weight of cement. For every percentage of fibre, a total of three cubes were cast to obtain average results. Addition of fibres into concrete greatly improves the engineering properties of concrete. Be that as it may, the compressive strength of concrete is still under level-headed discussion by the addition of fibres in concrete. There is no considerable improvement in compressive strength of concrete by the addition fibres. To improve the compressive strength of concrete there is a novel technique by the addition of Bacillus bacteria and its nutrients to concrete may in improves the mechanical properties of concrete. The bacteria used in this study are Bacillus Subtilis spore powder of 2 million CFU/gm with 0.5% of cement was mixed to concrete. And calcium lactate was added to concrete as a nutrient source for bacteria in concrete. Findings of this investigation indicated the influence of added bacteria in fibre concrete which is quite impressive for improving the compressive strength and workability of concrete.

Comparative Study on Modelling Techniques of Cable-Stayed Bridges

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 28th February 2018

Prafulla M. Hiremath | R. S. Sonparote

Abstract

The analysis of cable-stayed bridges is much more complex than that of conventional bridges (such as truss and girder bridges) due to their huge size and complicated nonlinear structural behaviour. Over the years, researchers have proposed different methods and software to model and analyse cable-stayed bridges but each has their own drawbacks. This paper concerns with the comparison of modelling techniques of the cable-stayed bridge in MIDAS Civil and Staad Pro software. The cable-stayed bridge chosen was symmetrical with cables having a semi-fan configuration. The bridge had H-shaped pylon and the span cantilevered 50 metres on both sides. The bridge was analysed for gravity loads and the results obtained from both the software were presented. It was inferred that all analysis cases need to be considered to arrive at most desirable solution and MIDAS civil might be the preferable tool

Prateek Bhatia | U.K. Dewangan

Abstract

This paper compares the variation in design capacity of flexural and axially loaded elements due to the difference in the design curves in the IS: 456-2000 and IRC: 112-2011. A bridge deck slab section is selected as a flexural element and a bridge pier column section is selected as an axially loaded element with the uniaxial bending moment. Their design capacities are calculated on the basis of the design curves as per the above codes. An interaction curve for axial compression with uniaxial bending is also plotted in MATLAB for given column section with respect to the design curves of both the code. It concludes that new design curves for concrete and steel increases the flexural design capacity of the section significantly but variation in P-M interaction curve is not significant.

Comparison of Different Roof trusses Under Wind Load

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Prince Yadav | Debarati Datta

Abstract

Trusses are triangular frame works, consisting of essentially axially loaded member which are more efficient in resisting external loads since the cross section is nearly uniformly stressed.Trusses are used in roofs of single storey industrial buildings and multi storey industrial buildings. The loads on the roof truss are dead load, live load, wind load and earthquake load. Trusses are also used to support long span floors of multi storey building to resist gravity load. The axial forces in members are calculated by taking these loadings and their critical combinations.For design of trusses, effect of wind force is predominant to calculate the member forces. SP 38(S&T):1987-provides designing for structures with steel roof trusses and their weight comparison. It gives details of specific roof truss configuration. This Paper represents analysis and design of roof trusses whose configuration are other than that specified in SP 38(S&T):1987. However their span to depth ratio is same as the truss configuration given in SP 38(S&T):1987. The trusses which has been analyzed having span 12m, 18m and 24 m and angle section has been used for design purpose. The analysis has been done for three basic wind pressure 100 kg/m2, 150 kg/m2 and 200 kg/m2, So that we can compare the weight of these trusses with A-type roof truss of having same span which is specified in SP 38(S&T):1987.The purpose of this study is to suggest the most feasible truss section, when longer span roof sheets are used. Now a days roof sheets of longer span are available in market. So we can use the configuration which have less number of purlins or wider panel. The truss configurations are distinguished between three categories namely Pitched roof trusses, Parallel chord trusses and Trapezoidal trusses. The advantages and disadvantages of different truss configuration are discussed in detail

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

S. Rajasekhar | R. Bhaskar reddy,Dr. B.Jayachandraiah,Dr. S. Sunilkumar Reddy

Abstract

Diesel engines are being used extensively for fuel economy but due to gradual depletion of Petroleum resources and increase in exhaust emissions, there is an urgent need for suitable alternative fuels for the diesel engines. As our country is an agricultural country, if the alternate fuels are produced by our farmers it will be beneficial for the country and the farmers also. In recent studies, researchers studied various vegetable oils like canola oil, aloveera oil, soya been oil, flaxseed oil and hone oil etc. Out of all flaxseed oil and hone oil play an important role as an alternative fuel. But the properties of flaxseed oil and hone oil are not suitable for the usage in the existing diesel engines without blending with diesel fuel. The performance of the engine depends on the combustion phenomenon and it further depends on the amount of heat retained in the combustion chamber. Hence the present work is planned accordingly to develop an insulated engine by coating the piston with TIO2 material. So that more amount of heat will be retained in the combustion chamber which aids the combustion. Further the performance of flaxseed and hone oil blends by equal proportions with diesel namely B10(5%of flaxseed oil+5%of hone oil), B20(10%of flaxseed oil+10%of hone oil), B30(15%of flaxseed oil+15%of hone oil) and B40(20%of flaxseed oil+20%of hone oil) are tested and the results are mentioned accordingly.

Comparison of Various Direct Displacement Based Approaches for Seismic Design

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Sourabh Kriplani | Onkar G. Kumbhar,Ratnesh Kumar

Abstract

Contemporary seismic design procedure proposed in various national codes follow the force-based design approach. Force based method holds good for building behavior in elastic domain, whereas the precise inelastic behavior of same building during severe seismic event is unpredictable. Some performance assessment guidelines like FEMA 445 provide cumbersome iterative procedure to ascertain the seismic performance of buildings. The iterative procedure of FEMA 445 is difficult to be performed in design offices for regular buildings. Therefore, a design methodology based on anticipated nonlinear performance is desired. Moreover, the design method should be robust and shall involve few or no design revisions. Relative displacement or drift of different levels of building under seismic event is one of the primary reasons of structural damage. Structural damage can be evaluated on the basis of cracking or deformations or in terms of dimensional changes i.e. strains. Indirectly by controlling displacement/drift of structure, damage can be controlled. Therefore, a relatively new technique of performance based seismic design i.e. Direct Displacement Based Design (DDBD) has evolved in last two decades. The approach of Direct Displacement Based Design method (DDBD) proposed by many researchers differ from each other in terms of effective viscous damping equation, displacement profiles and consideration of mode shapes. The study presents the variation in magnitude of seismic base shear and storey shear amongst various DDBD approaches and compares with the currently prescribed force based approach in Indian seismic code. The study also evaluates the advantages as well as disadvantages of these methods.

Abstract

The environmental change and ecological preservation are the principle issues of this century. India ranks as the second biggest in the populace, the fourth biggest in energy utilization and third biggest greenhouse maker and blazes ten folds fuel wood when contrasted with the United States. With a specific end goal to control the greenhouse outflows and for empowering countries for taking applicable measures the UN has concocted the matter of carbon exchanging on the premise of discharge moderation accomplished by the government and corporate firms by employing environmentally friendly technology for their production activity. The coal fired power generation in India is the greatest polluter and in the meantime gives the greatest chance to outflow lessening and procuring of carbon credits. In no time, India is creating the second most astounding number of carbon credits on the planet and is next just to China. In contrast with the developed countries the carbon emission level in India is substantially less. This gives enough opportunities to its industry to convey carbon units and seat points of interest out of its exchanging. With this vast potential to acquire carbon credits, India has a enormous degree for carbon consultancy organizations to flourish and is going to add another extent to the environmental and wealth related organizations zone. This paper presents an estimation of emission mitigation and carbon credit for a biogas electricity plant located in Maharashtra

Correlation between Half-Cell Potential and Corrosion Current Density for Corrosion Assessment of Rebar in RC Structures

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 26th February 2018

Anjali K. Dudhyal | 

Abstract

Corrosion of steel embedded in reinforced concrete (RC) structures is a major problem resulting in reducing the service life and durability of RC structures and causing early failure of the structure. Corrosion also costs significantly for inspection and maintenance of deteriorating RC structures. Hence, for preventing premature failure of RC structures, assessment of reinforcement corrosion is of significant importance. Practically, based on visual observation or using qualitative electrochemical techniques like half-cell potential measurement, the level of corrosion can be evaluated. Since for existing structures, it difficult to calculate the rate of corrosion using quantitative electrochemical techniques like Tafel extrapolation technique, linear polarization technique etc. as the instruments require direct contact with corroding steel rebar. Such measurements require damaging the small area of the structure and besides this, the potential/current scans applied to reinforcing steel during measurements may accelerate the corrosion process. Hence it is essential to corroborate relation between qualitative and quantitative techniques used for measurement of corrosion. The present paper aims to establish the relation between two electrochemical techniques namely, half-cell potential and Tafel extrapolation technique. For experimental work, RC slabs reinforced with four steel bars were cast and subjected to accelerated corrosion. The electrochemical measurements were recorded every day till the completion of tests to establish the relation between Half-cell potential and corrosion current density values obtained from Tafel plots.

Correlations between Microstructure, Nitrogen Concentration and Micro Hardness of Nitrided Ferritic Stainless Steel

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 16th May 2018

Patthi Hussain | Muhammad Azwam Ibrahim

Abstract

Gas Nitriding on Ferritic Stainless steels AISI 430 carried was out at 600 , for various period of nitriding process which were for 2 h, 8 h and 24 h. The effect of nitriding process period in term of microstructure, overall micro hardness, cross section hardness and nitrogen diffusion rate were investigated. The microstructures of the samples were carried out using Optical Microscope (OM) and Scanning Electron Microscope (SEM). The phase changes and Nitride precipitation formation were observed with respect to holding time of nitriding. Micro-analyses were also conducted on all samples using Energy Dispersive Spectroscope to investigate the effect of phase changes and it correlation toward the hardness of the materials. Unnitrided ferritic stainess steel was found having bigger grain size boundaries compare to nitride ferritic stainless steels. This is due to heat treatment during manufacturing process and concentration of nitrogen inside the steel. The size of grain boundaries reduces with nitriding time due to concertation of nitrogen inside the steels. The hardness value and concentration of nitrogen inside the steel reduce with the depth under the surface. The concentration of nitrogen in the steels increases with time of nitriding. Increasing in nitriding time increases the nitrogen composition inside the steel, thus reduce the grain size of the microstructure significantly and thus increase the hardness properties of the materials.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 19th March 2018

K.Sravanmathur | R.Murugan, V.S.Hariharan

Abstract

An axial flow compressor is a pressure developing machine. It is a rotating, airfoil-based compressor in which the working fluid principally flows parallel to the axis of rotation. This is in contrast with other rotating compressors such as centrifugal compressors, axial flow centrifugal compressors and mixed-flow compressors where the air may enter axially but will have a significant radial component on exit. The energy level of air or gas flowing through it is increased by the action of the rotor blades which exert a torque on the fluid which is supplied by an electric motor or a steam or a gas turbine. In this work, an axial flow compressor is designed by varying aspect ratios (ratio of blade height to axial chord length) where blade height is kept constant and 3D models are modelled using Pro/E. The present material used is Chromium Steel it is replaced with Titanium alloy and Nickel alloy. CFD analysis is done to verify the flow characteristics of fluid under turbulent conditions by applying the mass flow rate and inlet pressure, outlet pressure, velocity and mass flow rates. Structural analysis is done on the compressor models to verify the strength of the compressor for all the materials chromium steel, titanium alloy and nickel alloy by applying pressure which is output from CFD analysis. The analysis is done in Ansys.

Abstract

Piston is made of aluminium alloys is a crucial part in internal combustion engine. When the combustion of fuel take place insides the engine cylinder, high pressure and high temperature will be developed as the engine will operate at high load and at high speed. As a result of this high thermal and high structural stresses in the piston is produced inside the engine cylinder and if these stresses exceeds the designed values, the failure of piston take place. To avoid the failure of the piston thermal and structural intensity should be reduced to safe allowable limits. In this work an attempt is made to reduce the thermal and structural stress intensity by coated the piston with ceramic material. Thezirconium-based ceramic coatings are used as thermal barrier coatings owing their low conductivity and their relatively high coefficient of thermal expansion. The main objective is to investigate and analyze the structural and thermal stress distribution of the piston at the real engine condition during combustion process. The analysis is carried out to reduce the stress concentration on the upper end of the piston .i.e. piston head/crown and piston skirt and sleeve using ANSYS software. The result obtained is compared to select the better material for piston manufacturing.

Abstract

The project aims to define foam quality of different surfactant solutions on the basis of its visual and tactile attributes. A consumer is inclined to choose a detergent which forms lather instantly and the one which produces a feeling of slipperiness (so as to reduce the effort). These tactile attributes may rather be correlated with detergent properties such as the one which helps it to produce more amount of foam and the one which produces softer and creamier foam. Properties such as amount of lather, bubble size distribution and its density can be easily measured through standard instruments but the tactile attributes like slipperiness, softness and stickiness cannot be quantified as such. Such properties need to be correlated with quantifiable properties like viscosity, pH and friction between fingers. These correlations will facilitate the quantification of tactile attributes which would further help in laboratory scale classification of different foams of detergent solutions. One of the critical parameter that is important with respect to the tactile feel of materials is friction. This work describes the design, construction and use of a friction measurement system that can be used to evaluate coefficient of friction for different surfaces under varied lubrication conditions. The system has been designed so that it is very cost effective to manufacture, and provides all the necessary information about contact forces. Experiments are normally conducted by stroking the stationary surface using finger; provision has also been made for carrying out experiments with an artificial finger. Capacity and accuracy of load cell are less than 4N and 0.1%. In-vivo friction coefficients of skin of arm is varied from 0.3 to 1.42 dependent on condition under which experiment is carried out i.e with addition of surfactants or oil or water or under dry condition, normal load, counter surface materials and its textures.

Abstract

Automobile bumper is structural component of an automotive vehicle which is designed to prevent or reduce physical damage to the front or rear ends of passenger motor vehicles by absorbing the impact energy and distributing the stress perpendicular to the direction of impact. Beside the role of safety, fuel efficiency and emission gas regulations are being more important in recent years that encourage the manufacturer to reduce the weight of passenger cars. A well-designed car bumper must provide safety for occupant and essential elements of the vehicle and should have a low weight. The aim of this research is to enhance the performance of frontal impact beam (FIB) by optimizing the structural parameter using crash and modal analysis. It is proposed to manufacture FIB using Glass Fiber Epoxy (GFE) Hybrid composite material. New composite is developed to fit the design parameter. The mechanical properties like Young's Modulus, tensile strength and density are obtained by lab testing. Finally, obtained properties of (GFE) Hybrid composite material are used for simulation and modal analysis and results have been verified with existing FIB material. The careful design and analysis of FIB parameters are carried out in order to optimize the strength and reduce the weight. The results shows that material can minimise the bumper beam deflection, impact force and stress distribution and also maximize the elastic strain energy. The analysis was done according to the conditions stated in Indian regulation Ministry of Shipping, Road Transport and Highways (Department of Road Transport and Highways), Government of India, and complies with the test condition given by Automotive Research Association of India (ARAI) norms. In this paper, modeling, meshing and crash analysis are carried out using software CREO, HyperMesh and LS_DYNA Respectively.

Abstract

In the constantly changing manufacturing world, passion for metal cutting is crucial to stay ahead. Cutting tools are often designed with inserts or replaceable tips (tipped tools). In these, the cutting edge consists of a separate piece o f material, brazed, welded or clamped on to the tool body. They are usually indexable and low cost. This saves time in manufacturing by allowing fresh cutting edges to be presented periodically without the need for tool grinding, setup changes and without changing the programs. Different tool inserts are used for various applications and could be of various shapes like diamond, square, hexagon, triangle, round, octagon, etc. The incoming tool inserts could be sorted based on various shapes, dimensional accuracy, orientation and that if they are used or unused tool inserts. The sorting process consists of use of Image processing to grab the image of the inserts and then processing it through MATLAB software. The software will process the image for above said parameters and results would be generated on screen. A complete database for a given tool insert will also be generated and be available to the user whenever required and then the inserts would be placed in the respective bins. This paper presents a review on need of sorting tool inserts, various methods used for the same and methodology used for the automated sorting of tool inserts

Abstract

Now a daysRollover accidents are among the most dangerous type of vehicular crashes. They account for the highest fatality rate with more than 10,000 people killed every year in a rollover accident. Sport Utility Vehicles and light weight trucksare more susceptible to rolling over, because they have a higher center of gravity. In this paper the mechanism reports into the enhancements in vehicle dynamics by changing the height of centre of gravity by suitable methods. The main objective of the mechanism is to lower the height of centre of gravity during turning and thus enhancing the vehicle dynamics. Present day cars run at fast speeds and are getting faster day by day. As speed increases the threat to the lives of driver and passengers and other road pedestrian also increases. The major threats to human life are skidding and toppling. In this mechanism hybridizing of both the concepts i.e. turning and tilting at the same time has achieved. By altering the orientation of the front assembly,new mechanism designed which imparts entirely different orientation to the wheels while turning. Hence by changing the orientation it is able to tilt as well as turn the wheels extracting maximum benefits from this system which are being discussed in this paper. System modifies the steering mechanism of the vehicles. It has the unique ability to turn as well as tilt the front wheels simultaneously while synchronizing it with the tilting of the front wheels.

Abstract

Mixing is one of the most primary operations in industries like chemical, Biochemical, paper, food, cosmetic, and pharmaceutical applications. Though the customer have standard sized agitator with standard parameters but this method is time consuming as well as it consumes the more power for a batch type process. So the customer needs to design optimum agitator which runs with optimum power and time to perform its function. Further he requires small sized agitator which runs continuously without interruption the process flow. In this work the power requirement for small size agitator to mix two fluids are analyzed with optimum time. This paper describes the mechanical design of agitator to mixing polyectrolyte having viscosity 1.5cp considering the fluid forces that are imposed on the impeller by the fluid. The analysis shows that the forces are a result of turbulent flow of fluid and static fluid forces. The loads are dynamic and are transmitted from the impeller blades to the agitator shaft and then to the gear box. Agitator design is often though as the application of two engineering disciplines. The first step is process design from a chemical viewpoint and involves the specification of the impeller pattern, speed, temperature and blade angle etc. The next step in the design sequence is the mechanical design of the agitator component. The approach is straight forward design for the power (torque & speed) then shaft loads. The experiment is carried out for agitator 500 liter of capacity. Drawback of the old agitator is removed. The old agitator does not gives homogeneous mixing

Abstract

The project aims at designing a wheelchair capable of climbing staircases for physically handicapped people. The main conceptual elements that have been proposed to improve this idea are mainly to simplify the mechanism and make it work using minimum effort of human.In the field of providing mobility for the elderly or disabled the aspect of dealing with stairs continues largely unresolved. This project focuses on fabrication of the stair climber, a duel section tracked wheelchair capable of negotiating the large number of twisting and irregular stairs typically encountered by the residents living on the slopes. This wheelchair extends the capabilities of traditional powered devices by introducing control and navigational intelligence. These devices can ease the lives of many disabled people, particularly those with severe impairments, by increasing their range of mobility. A standardized autonomy management system that can be installed on readily available power chairs which have been well-engineered over the years has been developed and tested. A behaviour-based approach was used to establish sufficient on-board autonomy at minimal cost and material usage, while achieving high efficiency, sufficient safety, transparency in appearance, and extendibility. So far, the add-on system has been installed and tried on two common power wheelchair models. Initial results are highly encouraging

Abstract

A wind turbine is a device that converts kinetic energy from the wind to mechanical energy. Wind energy is one the most widely used renewable energy resources. Micro wind turbines need to be affordable, reliable and almost maintenance free for the average person to consider installing one. Micro - scale wind turbines produce more costly electricity than large and medium - scale wind turbines, especially in poor wind sites and in autonomous applications that require a high level of reliability. However, when designed properly with proper materials, micro - scale wind turbines could be a reliable energy source and produce valuable energy not only in developing countries but also in remote areas that are far away from the grid power in developed countries. Micro - scale wind turbines are in fact becoming an increasingly promising way to supply electricity in developing countries. The micro - scale wind turbines have quite different aerodynamic behavior than their large - scale counterparts. In this work the blades of the wind turbines are designed for low wind speeds of 3 m/s using NACA 2412 aerofoil. This paper elaborates the design of wind turbine blade using Q-Blade and 123D- Make software and fabrication using advanced light weight materials like Carbon fiber and PU foam.

Design and Fabrication of Precession Square Hole Drilling

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 13th July 2017

Abijeth kc | Avinash s,Avinash mp , Balu n , [6]Dr C Anilkumar

Abstract

Hole serves various purposes in all machine elements. These holes may be round, square, rectangular or any other shape depending on the requirement or design. This paper discusses the mechanical design and simulation of a square hole producing tool based on Reuleaux Triangle. The main aim of this paper is to investigate how a circular motion can be converted into a square motion by purely a mechanical linkage; an application of which is to construct a special tool that drills exact square holes. A geometrical construction that fulfils the laid objective is Reuleaux Triangle. Additionally, for this geometry to work from a rotating drive (such as a drill press) one must force the Reuleaux triangle to rotate inside a square, and that requires a square template to constrain the Reuleaux triangle as well as a special coupling to address the fact that the centre of rotation also moves. The practical importance of this enhancement is that the driving end can be placed in a standard drill press; the other end is restricted to stay inside the fixed square, will yield a perfectly square locus and this can be turned into a working square-to drill hole.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 10th April 2018

Pranav Mehata | Ramdevsinh Jhala, Atal Harichandan

Abstract

The new mixed mode solar dryer was designed and developed. As the open sun drying technique was time-consuming as well as less efficient, the natural convection solar dryer of mixed mode was designed and developed. The design and mathematical modelling of the two-parameter absorber plate outlet temperature and the relative humidity was carried out. The dryer was operated without any load inside it and operated for the two months. The average wind speed was measured to be 0.50m/s whereas the average solar insolation was 1200W/m2 received over the inclined plate. The designed value of the absorber plate was 2.0 m2.The drying chamber was made of plastic sheet in which spectrum of solar insolation which tends to discolouration of the food products or agricultural is prevented.

Abstract

Diesel engines are advantageous in terms of lower fuel consumption, lower unburned HC* and better fuel efficiency. Counter side they are disadvantageous in terms of high particulate emissions that results from fuel pyrolysis at high temperatures. These particulate emissions have antagonistic effect on both environment and human health. To regulate these diesel particulates, government is imposing stringent emissions norms on diesel engine exhaust. Therefore, it is important for all engine manufacturers to design and develop a system that is capable of measuring these particulate emissions. Further, diesel particulate matter is very complex structure, primarily composed of solid carbon with several absorbed species like ash, metallic abrasion particles, sulfates and silicates, which cannot be measured directly by analytical instruments based on direct detection method. The best approach to measure diesel particulate matter is based on the gravimetric method by using the device known as dilution tunnel. The present work focuses on design and numerical analysis of partial flow isokinetic dilution tunnel in order to determine the optimum mixing length to achieve complete mixing between the dilution air and exhaust sample. A commercial ANSYS FLUENT software has been used to perform the numerical simulations. To find optimum mixing length, various simulation test were conducted which can be categorized in three broad divisions. The first test consists of 9 different conditions based on variation in duct diameter and dilution ratio (DR) for constant duct length of 2500 mm. Results from first test shows that the shortest mixing length of 1250 mm was obtained for duct diameter of 150 mm when dilution ratio of 20:1 is maintained. Further, in order to reduce the mixing length, test 2 and 3 were conducted by introducing number of perforated plates and grid of cylinders only to best design of test 1. Results from test 2 and 3 shows that mixture gets uniform within 1000 mm of duct length when perforated orifice plate was used. The introduction of a grid of cylinder does not influence quick mixing of exhaust sample with diluted air.

Abstract

Solar energy is the most available, environmental friendly energy source and also renewable to sustain the growing energy demand. There are particular challenges in the effective collection and storage of solar energy though it is free for capturing. Solar energy is captured by solar collectors and an evacuated solar collector is the most efficient and convenient collector among various kinds of solar collectors. In the present study, the heat transfer characteristics of MWCNT – Demineralized water nanofluid as Heat transfer Fluid (HTF) is used in concentric type heat exchanger tank are presented. The heat exchanger is fabricated from copper concentric inner tank with a length of 1100 mm and Dia of 230 mm and with outer SS tank of length 1150 mm and dia 252 mm. The weight fraction of nanoparticles was 0.1% with the nanoparticles dimension ranging 20nm- 40 nm. Sodium Dodecyl Sulphate (SDS) as surfactant and Chitosan as dispersant was used in this experimental study. The performance of the concentric heat exchanger tank with Evacuated tube solar collector (ETSC) using MWCNT nanofluid as heat transfer fluid was compared with conventional solar water heater tank. The present study revealed that the maximum efficiency was found to be in between the range of 10% - 20% more than the conventional water heater in a day. The results of this study have technological importance for the efficient design of concentric heat exchanger tank to enhance heating performance of water even at low incident radiations. The collector efficiency shows greater enhancement with the use of MWCNT nanoparticles at a 0.1% weight fraction. In conclusions, results suggest that MWCNT Nanofluid can be used as the working fluid in an ETSC to absorb heat from solar radiation and to convert solar energy into thermal energy efficiently

Abstract

Automotive chassis frame is most crucial element that gives strength, stability and is the structural backbone of any vehicle whose role to provide skeletal frame to which the body of an engine, axle assemblies are affixed. The chassis frame must be rigid enough to withstand the stresses, shocks and deformation occurring and its main function is to carry the maximum load for all designed operating conditions with safety in mind. Considering the fact that in India commercial vehicles carry non-uniform loads, that leads to the failure possibilities in the chassis frame. An important consideration in chassis design is to have adequate bending stiffness along with strength for better handling characteristics. Therefore, maximum shear stress, stiffness and deflection are important criteria for the chassis design. After a careful analysis of various research studies conducted so for it has been found that sufficient studies have not been conducted on variable section chassis concept. This paper emphasises on design modification in the Section of a frame and comparison of structural analysis of those sections and conventional type frame for higher strength. In this research work, we authors have adopted the dimensions of an existing heavy vehicle frame for conceptual structural changes through modelling and analysis with the help of ANSYS software.

Abstract

In the recent years, the construction industry is slowly shifting its focus from conventional method of construction to prefabricated construction. Faster rate of construction, affordability, eco-friendly nature, joint flexibility are some of the qualities due to which prefabrication is obtaining rapid recognition in this industry. People prefer the faster rate of construction which is provided by the prefabricated construction compared to the long and tedious work of the masonry construction. Large-scale projects now undertaken have a need to be completed in the shortest span of time, hence the concept of prefabrication will be a huge hit in the coming years. In this paper, an attempt has been made to analyze the load carrying capacity of the prefabricated structure against the seismic forces. This paper shows the time history analysis results of a single degree freedom system and the multi-degree freedom system. A framed structure is designed using the codal provisions of IS456:2000. A comparative study has been made for a rigid building and precast building where the joint stiffness is reduced due to the introduction of precast joints. It has been observed that the precast joints are more flexible than the rigid joints; provided the precast joints are designed properly otherwise these joints will become vulnerable to seismic loads.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 11th June 2018

Chetan S. Gaikwad | Shrikant B. Jadhav, Deepak A. More

Abstract

The availability and wide range of applications of low cost sensors have encouraged a demand for improved sensor performance. Smart sensors are becoming integral parts of system and are performing the functions that previously could not be performed. Displacement can be measured by using precise measuring instruments such as LVDT, laser instruments which offers high speed, high resolution and highly accurate laser sensors (non-contact linear position sensor) for measuring displacement and position. But all these instruments are very costly and require high maintenance and they are very complex in design. So there is need to develop a system which gives high accuracy as that of existing measuring instruments and should also have low manufacturing and running cost. Proposed system consists of unique design of flexural bearing which is highly sensitive to axial movement. Deflection of bearing is recorded by the strain gauges in the form of resistance. This resistance is converted into the voltage form using strain gauge module. This voltage is given to ARDUINO microcontroller and using MATLAB program the results are generated

Abstract

Today our world runs in this condition only because of invention of internal combustion engine. In internal combustion engine chemical energy of fuel is converted to thermal energy to give a mechanical work output. There is large amount of heat liberated during the combustion of fuel, In which only few amount of energy is converted in to useful work (60 to 80%) and the remaining heat energy is wasted. This heat is first conducted to engine cylinder and convected to air through surface called fins. In an air cooled engine low rate of heat transfer is the main problem. Excess temperature developed in the engine causes thermal stresses on the engine parts and piston sizing. In order to avoid this effect, the heat should be sufficiently removed, for this issue in this paper we discussing the heat transfer of different fin geometry under different forced convection conditions. The efficiency of heat transfer can increase by increasing the heat transfer coefficient. Motorcycle engine releases heat to the atmosphere through the mode of force convection. To solve this, fins are provided on the outer of the cylinder. The heat transfer rate is defined depending on the velocity of vehicle, fin geometry and the ambient temperature. Many experimental methods are available in literature to analyse the effect of these factors on the heat transfer rate. However, different fin geometries are modelled in CATIA V5 software and CFD analysis will be used to simulate the heat transfer of the engine block. The result from the software is compared with the existing geometries. The material used for the manufacturing of fin is aluminium alloy

Ashish Mor | C.M.Krishna

Abstract

The machine tool industry has gone through tremendous changes since its inception. CNC machine with proper fixtures has the capacity to fill this gap. This has excited this research work on design and development of fixture for CNC. Manufacturing processes are commonly affected by the low stiffness of the components limiting the quality and precision of the final product. Precision is one of the most important issues in the machining process, and the main cause for rejection of the part is due to static deformation and the dynamic vibrations. The static deformation is mainly affected by two factors: deformation due to clamping force, and geometrical distortions due to material removal. This paper presents an analysis to manufacture fixture, using reverse engineering, for sheet metal operation. These fixtures are made by incorporating additional features in the existing fixture to suit for sheet metal machining operation. For design of fixture, computer aided design by Fusion 360 and manufacturing by CNC milling machine is used

Abstract

The paper is mainly concentrations on design and fabrication of the ―APMM which is a replacement of conventional motors in many applications of it. This APMM can run on its own without any traditional input for fuelling it except for the initiation where permanent magnets has to be installed at first. It is a perpetual motion system that can energize itself by taking up the free energy present in the nature itself. This project enables to motorize systems with very minimal expenditure of energy. This works on gravitational force. The weight being hinged on the links which is held on the gears on the offset center being rolling around the center gear and axle. The center axle holding one ring, and the mass are held on the circumference on this ring, and during rotation, being powered by DC motor intermittently rolling and stopping, and the rotations continuation will continuously be generating electricity to charge the battery. Here the input energy is multiplied by 2 times for the output so can be termed as free energy. Gain energy, input versus output is more. The rotations provided intermittently by the motor propels the assembly to rotate continuously. Here say motor propels for half a rotation, the assembly rotates to have at least 2 to 3 rotations independently and again by the end of those the motor propels momentarily, by this theory the power gain is affected. In this model, we are using existing available motor and available generator and not the required calculated rating which would have given us the gain through proper tabulations and in terms of wattage or amperes, but here we are showing that the power is generated even during the motor is in idle condition

Abstract

The most promising alternative fuel will have the greatest impact on future society. The rapid growth of environmental pollution, energy security and future fuel supply, the non petroleum based alternative fuels are used to increase the efficiency of the fuel and impact on green house gases. LPG is a mixture of petroleum and natural gases that exist in a liquid state at ambient temperatures under moderate pressure (less than 200 psi). LPG has a high Octane rating, which indicates that the engine operated by LPG would be more efficient than that of equivalent petrol engine. LPG has been used as an alternative fuel in the existing S.I. engine with slight modification in the fuel supply system. The vaporizer is required to convert the liquid fuel into vapour supplied to the carburettor. The working of the experimental setup is four cylinders, four stroke petrol engine with the solenoid actuator. The actuator allows LPG to the carburetor through the vaporizer kit. LPG is metered by hanging type weighing scale. Methanol is added with LPG by volume under gravity before vaporizer kit. Engine hot water heats up the vaporizer kit for raise in temperature of LPG and to evaporate the methanol easily. The petrol engine is started with LPG and then it is run by a mixture of LPG and methanol by adjusting the LPG flow. The performance and emission characteristics of engine are investigated by varying the quantity of methanol and LPG. The thermal and mechanical efficiencies are increased with addition of methanol and the specific fuel consumption is decreased. The emission characteristics like CO, CO2, HC and NOx are also reduced

Design of Precast Concrete Panels for Basement of Building

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd March 2018

Deepak Singh | Dr. R.S. Sonparote

Abstract

Basements are generally used as a utility space for a building where mainly parking is located. However, all the works are to be done in the congested underground environment inside the basement pit in confined space. In such places, precast concrete panels can be used. To make the application of precast concrete pavement economical and material effective, an attempt has been made to provide a curved bottom face. Curved panels are easy to place, consume less material, and are cost efficient making them more economical. They provide better consolidation of soil due to the curvature provided at the bottom face as compared to a regular (flat based) concrete panel. In order to optimize the curve, that needs to be provided at the bottom face, finite element analysis has been performed. The curved panels are optimised, based on the maximum shear force and bending moment obtained through analysis. Comparison of the key design parameters is made between the curved and regular panel. It is observed that values of optimised curved panels are less to regular panels.

Kushali Sindhia | Madhumitha Prakash,Dr. S. V. Satish

Abstract

In today's industrial scenario, labor is a major expense in any product that is manufactured even in developing countries. In this regard most of the present day industries are shifting towards automation. In our project, we are designing a smart roller shutter system for low cost operations. Roller shutters have many applications some of which include factories, garages, schools and warehouses. The project prescribed provides excellent security benefits and in regions exposed to inclement weather, it can also be used as a method of insulation. Studies show those automatic roller shutters already in market have been the cause of a large number of accidents over the years. A lot of these incidents take place due to the failure of mechanisms during normal working hours or emergency situations. Introduction of a few smart safety sensors in this mechanism can help reduce the risks and accidents caused by these shutter operations. In conclusion, we wish to develop a system to help minimize the health hazards caused by the failure of automatic roller shutters.

Abstract

layer turbine. It was invented by Nikola Tesla in the year 1908 and patented in the year 1913.It works on Boundary layer theory. The boundary layer is responsible for the rotation of discs with increase in the individual pressure in the cross section. As the world is getting polluted more and more by harmful gases from the burning of fossil fuels example: IC engines, the need for the alternate way of getting the work output has to be the key goal of today’s engineers. As tesla turbine can run on water, compressed air and steam. Hence these are all abundantly available resources which can be utilized to get the max efficiency from the turbine. Tesla turbine gives maximum efficiency when run on steam, as steam generation is difficult and not ideal for small scale projects we decided to go for compressed air. As stated by tesla the efficiency of this turbine is around 95%. Hence this turbine was chosen for the major aim of the project. In total two models where prepared from plastic practically and tested and final model is a computerized model in proportionate to the previous models.

Abstract

A crankshaft can be called as the heart of any I.C. engine since it is the first recipient of the power generated by the engine. Its main function is to convert the oscillating motion of the connecting rod into rotary motion of the flywheel. The main function of a camshaft is to convert the rotary motion of the crankshaft into vertically reciprocating motion of the valves required to open and close the intake and exhaust valves of engine cylinders, with the assistance of cams located on it and an intermediate mechanism. The crankshaft is subjected to bending stress and torsional shear stress, whereas the camshaft is mainly subjected to compressive stress due to contact pressure, galling and wear and tear. This project aims at designing of I.C. engine multi crankshaft and camshaft using standard design procedures. Further, Creo software is used to create 3-D models of crankshaft and camshaft. After creating the models, the static structural analysis is performed for both of these using different materials and boundary conditions using ANSYS software. A static load testing is performed on the crankshaft and camshaft of a TATA Vista Quadrajet car using UTM and experimental stresses are compared with analytical stresses for validation purpose. Finally, the results of total deformation and equivalent (von-Mises) stresses obtained for different crankshaft materials like ASTM 100-70-03, GS-70, AISI 1045 and Inconel X-750, different camshaft materials like ASTM A532 and ASTM A536 are evaluated and compared with each other to select the best suitable material for manufacturing of crankshaft and camshaft

Abstract

Mobile robotics is a fast developing area due to their wide applications in exploration on-ground, under-ground, on-water, under-water and space. Detection and tracking of the paths followed by these robots are required to analyze their motion and to guide them through optimal path. This paper focuses on the application of image-processing for estimating the position and velocity of mobile robot on an indoor workspace. The motion of the robot on the workspace was captured using monocular vision system. In order to detect the path of the mobile robot, the obtained image was processed using a full featured high-level programming language-MATLAB. This work is fully dependent on how well the feature of the robot in the image plane was extracted and tracked from the initial frame to the subsequent frames. Thus, color-based feature extraction and blob analysis are used to serve the purpose of detecting the path of the mobile robot. The resulting data was further used to obtain path coordinates which in turn gives the position and velocity errors of the robot. A calibration phase was carried out to analyze the relationship between the measured coordinates (pixels) with the world coordinates. Some of the challenges faced during implementation of the system are also mentioned in the paper.

A. Selvaperumal | K. Ramasamy,Chinju Saju

Abstract

Agricultural sector is playing vital role in Indian economy, in which irrigation mechanism is of key concern. Our paper aims to find the exact field condition and to control the wastage of water in the field and to provide exact controlling of field by using the drip irrigation. It describes an application of soil moisture detector and gypsum block sensor (developed by AEC&RI) for controlled irrigation and real-time monitoring water content of the soil. Soil moisture detector is made up of two electrode probe to pass current through the soil, so we tend to read that resistance to induce the moisture level. Once the soil is dry condition the soil moisture detector measure the resistance and convert into volts. Soil moisture detector and relay actuates the solenoid valve. If solenoid valve open the pump is ON then the flow can happen by the pressure sensor, whereas the soil is the wet condition, the solenoid valve closes. Gypsum soil moisture sensor is the electrical resistance between electrodes embedded in a porous medium (block) is proportional to its water content, which is related to the soil water matric potential of the surrounding soil. Automation of irrigation systems has the potential to provide maximum water productivity by maintaining soil moisture in the field at optimum levels. This automated irrigation system works without wire and wireless technology. Hence the farmers can use the low-cost automated system in the field with the help of soil moisture detector and gypsum block.

Elif Ulusal | Goktug Hambarci, Gokhan Bayar

Abstract

One of the recognition tools used in the robotic researches is the IR distance sensor. The main reason for choosing this sensor is the availability in the market and affordable price. Besides IR distance sensors, laser scanning rangefinder is the other solution. Laser scanners can also be easily accessible in the market but the price of them may not be reasonable for the engineering students and individual researchers. The important challenge in the use of IR sensor is the calibration. Before adopting it into a real system, a calibration system and procedure should be created. Then, the calibration parameters are to be integrated into the system. To make a contribution in this subject, a calibration tool for IR sensors is developed in this study. The system developed includes an IR sensor, a 4-wheeled mobile robot and a laser scanner range finder. The mobile robot is driven by 2 dc actuators equipped with high-resolution encoders. The control of the robot’s motion is achieved by the use of motor controllers, encoder interface card, microprocessor and a computer. The laser scanner is directly connected to the base computer where the related data decoding processes are performed. The data coming from IR sensor, which provides distance data up to 5m, is processed in the microprocessor. The integration of the subsystems gives the opportunity to calibrate the IR sensor. The steps of the methodology proposed are given in detail in this paper.

Development of Scoring System for Seismic Vulnerability Assessment of Indian Model Building Types

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Shital J. Ingole | Dr. Ratnesh Kumar

Abstract

In order to reduce subjectivity in quick seismic vulnerability assessment a scoring system is used. The general procedure of seismic vulnerability assessment using scoring method requires the building to satisfy a Basic Structural Hazard (BSH) score, below which advanced analysis is required to be performed. A BSH score reflects the estimated likelihood of collapse of the building subjected to the maximum considered earthquake ground motions for the region. Development of scoring system is a complex procedure involving various parameters related to structural vulnerability and anticipated hazards. Different Model Building Types (MBT) possess different structural capabilities for resisting earthquake force, consequently, the BSH score differs for different MBT’s. Therefore, it is essential to identify MBTs based on its seismic resistance and develop scoring system for the same. Well established scoring system for buildings of United States has been developed by FEMA-155 based on detailed structural evaluation. However, for Indian MBTs only a few scoring system have been proposed and are primarily based on expert opinion rather than strong mathematical procedure. In present paper it is endeavored to develop score for Indian model building types. The present paper provides methodology to develop the BSH score for Indian MBTs by considering one model building type i.e. Concrete Moment frame (CM1). Further, the proposed procedure can be used to develop BSH score for other Indian MBTs.

Shubhendra P. Singh | -

Abstract

Gyrostabilizers are anticipated to be as appropriately desired system to provide stability for two wheeled vehicles. This paper focuses on the concept of developing the two wheeled vehicle prototype to exhibit the working of gyrostabilizer (or gyroscope) for providing stability. The stabilization of two wheeled vehicle works as torque applied externally on vehicle is neutralized by torque produced by gyroscope. When torque is applied vertically on the gyroscope normally to its spin axis, this causes to develop precession motion which process the gyroscope along its perpendicular axis. As following, the torque developed by gyroscope will counter the applied torque causes vehicle to be in equilibrium (i.e., gyroscopic effect). This paper exemplifies the latter described system in static condition. But, the paper also introduces further the development of the vehicle in dynamic condition. In this system, sensors with modified gyro wheel are implemented. Sensors actuate the gyro wheel according to the tilt of the vehicle to provide same magnitude of the torque exerted, externally

Abstract

In most developing countries, food preservation is a major problem. Farmers fulfill all food requirements, by giving good quality of products to the end users. But they fail to preserve the food for long time. Preservation is the technique in which food can be saved for a long time. Generally farmers prefer open sun drying for drying the agricultural products. In the rural areas of our country there is a very large amount of production of food, but because of lack of facilities there is no any special provision for drying. So they prefer the conventional open sun drying, but this method is not so effective, because it requires more time for drying. Also quality of the product gets hampered. In order to avoid such difficulties in preservation of food, solar drying is to be introduced. In this paper we made a solar dryer for ginger. Solar dryer have shown a very good result in preservation of the ginger from wastage, poisoning and other contaminants. The solar dryer is solely depending upon the renewable energy of sun. It does not use any fossil fuel for burning

Abstract

At present, energy problems are being encountered all around the world, which is creating several countries to scrutinize new energy sources. Such recent sources are known as alternative energy or renewable energy. Among alternative fuels for dieselengine application, biodiesel is very attractive because it is biodegradable, sustainable source, an environmentally-friendly and reduces green house gas emissions that can meet future energy demands. Researchers have always tried to develop internal combustion engine using biodiesel performing performance as well as characteristics of emission were carried out so far. There are, obviously, few uncertainties concerning its usage. The major significant doubt is use of B100 pure biodiesel fuel whether it is creates diesel engine problems or not. The current paper describes a experimental study of the effects of pure biodiesel(B100) usage on the fuel pump components and three types of fuel injectors by using of energy dispersive X-ray(EDX) and scanning electron microscopy(SEM) investigation of single cylinder diesel engine, which is redesigned into a supercharged diesel engine in this work, a single cylinder, four stroke engine, of Kirloskar make TV1 modified into a supercharged engine. A study of fuel injector fouling and crank case lubricating oil properties are measured. Also performance parameter brake thermal efficiency(BTE) is calculated. The results from performance are compared between diesel and B100 fuel combinations under different operating conditions. The maximum Brake Thermal efficiency is observed for Supercharged gauge pressure 1.5 bar at full load than that of naturally aspirated condition.

Distributed MPPT Connected With Cascade H-Bridge Multilevel PV Inverter for Grid Friendly Applications

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 22nd January 2018

M.Rajasekhar | M. Sai Sandeep,S.S.Deekshit

Abstract

This paper presents a modular cascaded H-bridge multilevel photovoltaic (PV) inverter for single- or three-phase gridconnected applications. The modular cascaded multilevel topology helps to improve the efficiency and flexibility of PV systems. To realize better utilization of PV modules and maximize the solar energy extraction, a distributed maximum power point tracking control scheme is applied to both single- and three-phase multilevel inverters, which allows independent control of each dc-link voltage. For three-phase grid-connected applications, PV mismatches may introduce unbalanced supplied power, leading to unbalanced grid current. To solve this issue, a control scheme with modulation compensation is also proposed. An experimental three-phase seven-level cascaded H-bridge inverter has been built utilizing nine H-bridge modules (three modules per phase). Each H-bridge module is connected to a 185-W solar panel. Simulation and experimental results are presented to verify the feasibility of the proposed approach

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd March 2018

S.Sangita Mishra | Chauhan Shuaib, Ansari Aadil, Jamadar Aatif, Shaikh Shadab

Abstract

Drought is a weather-related natural disaster affecting vast regions and causing significant structural and non-structural damages. Marathwada Region of Maharashtra, which is mainly located in the main drainage of Godavari River is facing severe drought every year. This region is characterized as a ‘frequently drought-prone area’, where drought can be expected every 6 to 10 years. Jalna District in Marathwada has a semi-arid climate with an average annual rainfall of 729.7 mm, and an average monsoon from June to September with rainfall of 606.4 mm. During the years 1875–2004, it has experienced drought 18 times, including the two years of successive drought in 1984 and 1985. Rainfall data for Jalna shows great year-to-year variability culminating in the extreme drought of 2012. In most cases, the drivers of droughts are context-specific, often inter-linked and act over different time scales. Therefore, the occurrence of drought must be understood and appropriate drought indices should be investigated for different goals such as agriculture practices, engineering practices and watershed management. This study aimed to identify the type of drought events, determination of drought severity, duration and spatiotemporal extension of drought for the planning of mitigation measures for farmers. Using the Standardized Precipitation Index (SPI) as an indicator of drought severity for the period from 1901 to 2002, the characteristics of droughts were examined. The multiple-time scaled SPI values were evaluated for June –October months in order to obtain severity of drought events over the years. The overall outcome of this study demonstrates that severe and extreme droughts were experienced from time to time across the study area leading to unfavourable results on agricultural practices and water resources in the area.

Abstract

Increasing demands for speed and efficiency in the face of greater complexity of modern construction projects have given rise to the need for proactive and dynamic management of resources. Safety and environment are added to traditional success criteria such as cost, quality, and time. This requires project managers to make better decision to align materials, labour, and machinery based on the information available. Radio Frequency Identification (RFID) is one such system that is widely used in supply chain management. The RFID technology is a means of gathering data about a certain item without the need of touching or seeing the data carrier, through the use of inductive coupling or electromagnetic waves. RFID is used to automatically identify people, objects, and animals using short range radio technology to communicate digital information between a stationary location (reader) and a movable object (tag). Use of RFID has improved Real-time traceability and visibility capability at the upstream and increased efficiency and quality of supply chain operations, especially towards the downstream (e.g. distribution, wholesale, and retail), in manufacturing business.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 29th June 2017

P. Manoj Reddy | Dr. A. Vimala

Abstract

There are two basic approaches to numerically evaluate the dynamic response of the structures. The first approach is numerical interpolation of the excitation and the second is numerical integration of the equation of motion. In the present study, the second approach (Newmark’s method) is used to find the response of a set of 40 structures idealised as SDOF system. The 40 structures are chosen in such a way that their time period varies from 0.1 to 4 sec. The response of all 40 structures is evaluated for 8 past Indian earthquakes. A program is developed in MATLAB to find the peak response of each structure for each earthquake using Newmark’s method. Average peak response of each structure under eight earthquakes is calculated. A response spectrum is developed as average peak response versus time period of 40 structures. As a second part of the work, the response of 40 structures is evaluated as per response spectra given in IS1893: 2002 based on time period of the structure. A comparative study is made between Newmark’s response and the response as per IS1893 response spectra. The study reveals that the responses calculated using IS1893 response spectra and Newmarks method are not similar for all the earthquakes

Abstract

Electrical discharge machining (EDM) is a process for shaping hard metals and forming deep and complex-shaped holes by arc erosion in all kinds of electro-conductive materials. The objective of this research is to study the influence of operating parameters of EDM of tungsten carbide on the machining characteristics. The effectiveness of the EDM process with tungsten carbide is evaluated in terms of the material removal rate, the relative wear ratio and the surface finish quality of the work piece produced. It is observed that copper tungsten is most suitable for use as the tool electrode in EDM of tungsten carbide. Better machining performance is obtained generally with the electrode as the cathode and the work piece as the anode. Tools with negative polarity give higher material removal rate, lower tool wear and better surface finish. High open-circuit voltage is necessary for tungsten carbide due to its high melting point and high hardness value. Dielectric using pressure is found to be optimal at 50 kPa. High material removal rate, low relative wear ratio and good surface finish are convicting goals, which cannot be achieved simultaneously with a particular combination of control settings. To achieve the best machining results, the goals have to be taken separately in different phases of work with different emphasis. In rough EDM of tungsten carbide, material removal rate is of primary importance. Thus, the higher the discharge current, the faster is the machining time. Material removal rate and the surface rough ness of the work piece are directly proportional to the discharge current intensity. When approaching the finishing stage, an optimum control setting is required for attaining the best surface finish and precision machining. For precision machining of tungsten carbide, the optimum condition of relative wear ratio and surface roughness takes place at a gap voltage of 120 V, discharge current of 24 A, pulse duration of 12.8 ms, pulse interval of 100 ms, dielectric ¯using pressure of 50 kPa and copper tungsten (CuW) as the tool electrode materials with negative polarity. This study confirm that there exists an optimum condition for precision machining of tungsten carbide although the condition may vary with the composition of the material, the accuracy of the machine and other external factors.

Abstract

Floor tile laying process is a finishing job usually done manually. This process is described in detail including the tile laying work flow, thinset thickness, tiles pattern, tools, tiles installation defects, costs and work rate. A cost analysis of tile laying process was made based on data obtained in one of the construction project in Langkawi in 2005. The labor cost was RM 1.50 per feet square of tiles. The material costs however vary with the quality and design of tiles. A field study was carried out to measure the work rate of manual tile installation where the average rate was 19.2seconds per tile of 300mm x 300mm. The existing research and robot technology is discussed in this research including the various configurations considered by the researchers. Based on these, important elements of floor tile laying automation were identified as lacks of data on tile laying work itself, manipulator design and costs effectiveness. We are here with new mechanized unit which can be more suitable for automation.

Abstract

In recent years various software are available for earthquake analysis of buildings like STAAD.Pro, ETabs and many more. There are multiple methods for earthquake analysis of a multi-storey building by this software. The aim of the paper is to compare two such methods by STAAD.Pro software. These two methods are when seismic weight is applied to the nodes and when applied on the beams. From this analysis comparison of storey shear at the different storey is observed. Moreover, storey drift and storey displacements at different floor level are compared.

Earthquake Analysis of Water Tank for Different Staging Height and Sloshing Effect

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd March 2018

Abstract

From the old experiences of few earthquakes, like Bhuj earthquake in India elevated water tanks were heavily harmed or failed. Liquid loads behave very differently to dry loads at the time of the earthquake. When the liquid starts to slosh in the tank, it causes huge weight shifts. Elevated water tank must remain functional after an earthquake as it is useful to provide water and firefighting system, Therefore it is important to study in detail. This paper presents a study of earthquake analysis of elevated water tank for different staging height having the same capacity. It is necessary to have a control system for effectively reducing slosh. The purpose of this study is to know the behavior of liquid under motion or vibration by comparing sloshing frequency numerically, experimentally and by ANSYS. And also to analyze the model of a water tank with different bracing patterns, staging heights to know the minimum deflections.

Earthquake Resistant Low-Rise Open Ground Storey Framed Building By Pushover Analysis

Abstract

Presence of infill walls in the frames alters the behaviour of the building under lateral loads. However, it is common industry practice to ignore the stiffness of infill wall for analysis of the framed building. Engineers believe that analysis without considering infill stiffness leads to a conservative design. But this may not be always true, especially for vertically irregular buildings with discontinuous infill walls. Hence, the modelling of infill walls in the seismic analysis of framed buildings is imperative. Indian Standard IS 1893: 2002 allows analysis of open ground storey buildings without considering infill stiffness but with a multiplication factor 2.5 in compensation for the stiffness discontinuity. As per the code, the columns and beams of the open ground storey are to be designed for 2.5 times the storey shears and moments calculated under seismic loads of bare frames (i.e., without considering the infill stiffness). However, as experienced by the engineers at design offices, the multiplication factor of 2.5 is not realistic for low rise buildings. This calls for an assessment and review of the code recommended multiplication factor for low rise open ground storey buildings.

Abstract

The significance of the transport sector lies not only in the specific services it renders, but even more in unifying and integrating influences it renders on the economy. Railways, an integral part of the transport network, play a crucial role in facilitating trade. In a large developing country like India, railways are a medium of long-distance transportation of passenger and freight. Good physical connectivity in urban and rural areas is essential for economic growth and bridges plays a crucial role in achieving this target. Generally, project planners perform comparative cost analysis up to Composite Cost (material cost & placement of span) without considering lifecycle cost and effect of depth of girder on the cost of approaches. In this present study, analysis of superstructure for 35m span has been performed under IRC loading with STAAD software and design has been carried out as per relevant IRC codes. An attempt has been made to include the factors of lifecycle cost and increase in overall cost of superstructure due to increase in the length of bridge approaches. After designing, estimation and costing of the superstructure have been carried out. Afterwards taking into consideration of all the cost stages like Basic material cost, Composite cost, Lifecycle cost and Combined cost, it is seen that Composite steel girder comes out to be an economical option for the first three stages but the scenario changes in case of Combined cost and Steel Truss comes out to be the best choice.

Abstract

Due to rapidly growing population, it is inevitable to construct multistory buildings and this calls for more and more space for parking. Generally, this requirement is met by introducing parking at ground floor and hence it is not possible to construct the brick walls to enclose ground floor completely. Similar situation is also observed while providing the refuge areas at intermediate floors for fire escape. This feature is called as soft storey and past records demonstrates that building with soft storey performed poorly during earthquake. Main reason behind the failure of building with soft storey, during earthquake is sudden change in stiffness, which causes excessive shear on the columns in soft storey. Hence, it is very much important to study the effects of soft storey on response of building. Further, appropriate care shall be taken during design to eliminate the effects of soft storey. Although, various researchers has studied this phenomenon and recommended the remedial measures, but the modeling techniques adopted for modeling brick infill is always questionable. Hence, it becomes important to study this phenomenon with more detailed considerations to empirical time period formulas proposed in IS1893 Part 1: 2002. Considering above facts, study has been carried out using G+7 building model, to validate the empirical time period formula proposed in IS1893 Part 1: 2002. Further, effect of soft storey on seismic response of building is also evaluated by considering G+7 building with soft storey at GF, 2nd Floor, 4th Floor & 6th Floor respectively.

Abstract

Soil stabilization has become the useful solution to treat the weak soil to achieve the required engineering properties. Soil stabilization by adding materials such as cement, lime, bitumen, etc. is the effective method for improving the geotechnical properties of soil which have been applied for many years now. This research is intended to study the effect of adding nanomaterials (nano-copper and nano-silica) on geotechnical properties of soil especially Atterbergs limit, compaction characteristics, unconfined compressive strength, CBR value and swelling pressure. Nanomaterials were mixed with soil in three different percentages (i.e. 1, 1.5, 2.5 % and 0.3, 0.6, 0.9 % by weight of soil). Based on obtained results, in order to reach the maximum increase in strength parameters, the optimum nano-copper and nano-silica content occur at 1.5 % and 0.6 %.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 28th February 2018

Navdeep Singh | Jagtar Singh

Abstract

Flux cored arc welding and submerged arc welding are widely known as high quality, high deposition rate processes, commonly used to join the plates of higher thickness in pressure vessel components. These processes provide a pure and cleaner, high volume weldment that has a relatively high material deposition than other traditional welding methods. In this research work high carbon steel plate SA 516 Gr. 70 was used to evaluate the best welding process for heavy thickness and good impact & tensile properties of HAZ and weld metal. Two test coupons were welded with FCAW and SAW welding separately. After welding the coupons were subjected to radiography testing and destructive testing such as tensile and impact test. There was significant difference found between the results and it was concluded that SAW welding is the best method which enhance the tensile and impact properties of butt weld joints of high carbon steel

Ashfaque Ansari | Prof. Mukund M. Mahajan

Abstract

Due to rapid urbanization and development of smart cities, paved areas have been increased rapidly. Un-paved pervious areas are converting into impervious paved areas, which affects on many environmental factors, such as ground water table, average atmospheric temperature and green house effect, which are major current issues for environmentalists. Pervious concrete is one of the solutions to defeat this problem and research has been done by many researchers all over the world on the effective utilization of pervious concrete, especially in pavement sector. Due to complex behavior of pervious concrete, it is difficult to maintain proper balance between strength and permeability. In this paper property of hardened concrete with various percentage of fine aggregate has been determined experimentally in addition to various tests have been conducted to observe important properties, like compressive strength, density and permeability. Influence of fine aggregate on these properties is presented in this paper. As there is no approved standard method to determine permeability of pervious concrete, falling head permeability test method has been used by preparing own apparatus. Optimum strength and permeability results have been obtained on percentage of fine aggregate less than 15 percent.

Effect of Geotextile on Unpaved Roads

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 22nd January 2018

S.Theerka Dharshini | M.Lokesh,D.Nanda Kishore,K.Sasidharan,M.Vimalanathan

Abstract

Unpaved roads are usually used for low volume traffic and it serve as access roads for rural areas. The performance of the unpaved roads depends on properties of the sub-grade soil . The geotextiles are used in the sub-base to improve the performance of the soil. However, the use of geotextile is uneconomical but it increases the service life of the unpaved roads and avoids large deformation in the roads. The maintenance cost for this type of roads is somewhat low compared to the roads without geotextile . This study is carried out experimentally, utilising the CBR testing arrangement. The penetration relation of the sub grade-woven geotextile-gravel, sub grade-nonwoven geotextile-gravel and sub grade-gravel is evaluated using CBR test. This test shows that the performance of the unpaved road is improved with the inclusion of the geotextile.

Effect of Groove Area on Angular Distortion in CO2 Arc Welding process

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd August 2017

B.N Sathyanarayana Reddy | H V Panchakshari, Viresh G Patil,K Thirupathi

Abstract

Angular distortion often occurs in butt welded joints when transvers shrinkage is not uniform along the depth of the plates welded due to non-uniform heating and cooling along the thickness of plates. This is the main source of mismatch and dimensional inaccuracy in large welded structures. There is need for procedural development and understanding the mechanism of residual stresses and angular distortion in connection with CO2 arc welding process. In the present investigation it is proposed to study the effect of different electrode diameter and edge preparations such as included angle and root opening on distortion in CO2 arc welding process on mild steel. The distortions considered for different edge preparations are angular distortions for single groove, bevel groove butt joints and analyze distortions in butt joints for 8mm plate thickness of size 250x250 in mm and then measurement of different distortions made by 3-D coordinate measuring machine. Angular distortion in single V-groove butt welded joints and bevel groove butt welded joints decreases with increase in the Groove area.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Sanjay U. Marjive | Dr. Ratnesh Kumar, Dr. L. M. Gupta

Abstract

This paper presents the influence of shapes of intermediate web stiffener for improving critical elastic buckling load of cold-formed steel lipped channels under axial compression. From the literature, it is observed that the influence of variation in shapes of intermediate web stiffener has not been studied in detail. Therefore, in the present study, the effect of variation in S1/b ratio (depth of intermediate web stiffener to the depth of web) for triangular and quadrilateral intermediate web stiffener on lipped channel sections of length varying from 0.5 m to 6.0 m have been considered. The thickness of the steel plate is kept constant as 1.50 mm, whereas, the ratio of the depth of intermediate web stiffener to the depth of web has been varied from 0.03 to 0.36. The members have been analyzed with both ends fixed and allow translation in the lateral direction. The elastic Eigen value buckling analysis has been performed on 300 models by using finite element analysis method. Local and distortional failure modes were observed for critical elastic buckling load. From the study, it has been observed that the effect of intermediate web stiffener decreases for member length larger than 2.5 m due change in mode shape i.e. local to distortional. It has also been observed that with the increase in depth of intermediate web stiffener the buckling load increases. However, as compared to triangular shape the quadrilateral shape intermediate web stiffener imparts larger resistance to buckling.

Abstract

This research paper studies the behaviour of different irregular plan buildings during seismic excitation. The building plans, which have eccentricity between center of mass and center of rigidity are subjected to more severe damages in compare to building plan which have no eccentricity between center of mass and center of rigidity. The buildings which have zero eccentricity perform well during earthquake. Most common shape of building plans as Square shape, ‘L’ shape, ‘C’ shape, and ‘T’ shape, which are repeatedly used in urban areas nowadays, which conforms as per clause 7.1 of IS Code 1893 (part 1)2002, are modelled by using ETABS software. Different parameters as Story drift, Story displacement and Torsion (Ratio of max story drift to average story drift) are studied for four models. After analysis using Linear Time history method, comparison of seismic performance of different models was performed and most vulnerable building shape against earthquake forces was located in this study.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 11th June 2018

Neelesh chaudhary | V.K. Singh

Abstract

Infill walls are considered to non-bearing structural members but affect not only structure masses also lateral rigidities which may cause free vibration behavior of the buildings. Although infill walls are not considered structural members, they are acting together with the frame when subjected to seismic loads. Analyze and calculation models including infill wall contribution are difficult and complex especially on major construction projects. Behavior of masonry infilled R.C. frames under seismic loads should be modeled to consider the effect of the infill walls on the seismic performance of the structure. In this study an overview of the modelling methods of infill walls in reinforced concrete frames is presented. The advantages or disadvantages of the presented methods are discussed and an easy and effective procedure is suggested for using in practice design. Present paper describe the nature of RC frame building with G + 11 storey with masonry infill materials of brick masonry. Completely fill, bare frame, soft storey, multiple opening frame models are studied. Effect on various parameters like base shear, displacement, storey drift etc are taking into account. Infill walls are modelled as pin-jointed single equivalent diagonal strut. All analysis was carried on software Etabs. Result from study conducted have shown that infill walls increases base shear, stiffness while displacement, time period and drift have been reduced.

Effect of Modified Provisions of IS 1893 (Part 2):2014,on Design Base Shear of Elevated Water Tanks

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Suraj O. Lakhade | Dr. Ratnesh Kumar, Dr. O. R. Jaiswal

Abstract

Elevated water tanks are essentially present in public water distribution systems. These tanks are regarded as lifeline structure due to their post-earthquake importance, which necessitates stringent code requirements for their seismic analysis and design. Recently BIS (Bureau of Indian Standards) has revised the provisions for seismic design of water tanks and published IS 1893 (Part 2):2014 which has significant modifications compared to the old code (IS 1893:1984). These revisions are largely based on IITK-GSDMA Guidelines (2007). However, some of the provisions in IS 1893 (Part 2):2014, particularly those related to response reduction factor and usage of 1-DOF and 2-DOF models need critical examination. In this paper, the main provisions of IS 1893 (Part 2):2014 are discussed.

Abstract

Geopolymer concrete is an innovative alternative material for cement concrete thus decreasing greenhouse emissions and leading to better construction practices and is produced by complete replacement of cement and water with fly ash and GGBS & alkaline activators. To examine the use of Geopolymer as replacement to cement, it is essential to study the properties of binders and their combinations in preparing Geopolymer mix. The present research aims at studying the effect of fly ash and GGBS combination on Mechanical properties of Geopolymer mortars and also the effect of Na2SiO3/NaOH ratios on the production of fly ash and GGBS based geopolymer. Sodium silicate and sodium hydroxide (NaOH) solution were used as alkaline activator with a NaOH concentration of 4M. The geopolymer samples were prepared with different fly ash and GGBS contents and Na2SiO3/NaOH ratios (1.5, 2.0, 2.5and 3).The main evaluation technique in this study were compressive strength. The parameters considered in this research work are proportions of fly ash and GGBS (100-0, 75-25, 50-50, 25-75 and 0-100), Ratio of Na2SiO3/NaOH, curing condition is taken as the outdoor curing.

Effect of Nano Filler on Mechanical Properties of Stainless Steel Glass Fibre Reinforced Fibre Metal Laminate

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 3rd February 2018

Satnam Singh | Surjit Angra

Abstract

Recent advancements in the field of fibre-metal laminates (FML’s) proved the superiority of fibre metal laminates over monolithic aluminium alloys in aerospace and aircraft structures. In this research flexural strength and Izod impact, energy absorption of stainless steel based fibre metal laminate (SS FML) with and without nano-clay was compared for the different orientations of glass fibre layers. Three point bend test and Izod impact test were performed on the universal testing machine and pendulum type Izod impact testing machine respectively. SS FML sheets were prepared using hand layup process. Standard size flexural and impact test specimens were cut from the prepared sheets according to ASTM standards. It was found that flexural and impact properties of SS FML were improved drastically after the addition of nano-clay into the composite matrix due to the dispersion of nano-clay particles in the composite matrix. The flexural and impact properties of SS FML were decreased as the angle of orientation of fibres was increased from 0° to 90°.

Abstract

Normally, industries and municipalities discharge the wastewater into open land or in water bodies without ample treatment due to which the ecosystem gets disturbed. For the treatment of wastewater, chemical coagulation is intended primarily to remove color, turbidity and chemical oxygen demand (COD) of the wastewater.

Abstract

In Civil Engineering, it is well known that the packing density of the particles in a concrete mix has great impact on the performance of concrete. High performance concrete (HPC) has become more and more popular in recent years. However, the various required performance attributes of HPC, including strength, workability and durability, often impose paradox requirements on the mix parameters to be adopted, thereby making the concrete mix design a very difficult task. This paper introduces the concept of packing density for increasing the performance of HPC. The concept is based on the belief that the performance of concrete mix can be optimized by maximizing the packing densities of the aggregate particles with manufactured sand (Type VSI) and fine particles. This paper involves the various mix proportions of aggregate particles with manufactured sand and study the behaviour of concrete and other parameters. Mix proportion includes the insertion of manufactured sand from 0% to 50% along with aggregates, thus to get the optimum packing density of the aggregate particles, the optimum packing density was obtained at proportion of 25% coarse aggregates (20mm downsize), 25% coarse aggregates (12.5mm downsize) and 50% manufactured sand. By using the optimum packing density combination in mix design of HPC and study the behaviour of concrete and its performance parameters. Using manufactured sand to fill the voids of coarser aggregates has increased the packing density thus by decreasing void ratio and making the structure dense and stiff. Thus increasing the packing density gives significant results on performance of HPC.

Abstract

Introduction: Margin placement is an essential requirement in any fixed restoration as it limits the boundary of the restoration and seals the implant abutment junction for entry of any debris or saliva, thus failing the restoration.2 The marginal fit of the cast restorations is essential for proper functioning, esthetics and success in the oral cavity. The aim of the study is to compare the effect of pattern materials on the marginal gap of cast copings fabricated on titanium implant abutment. Null hypothesis state no difference in pattern materials when tested for marginal fit over implant abutment. Materials& method: Two pattern materials: Inlay wax and Margin wax were used in the present study. And patterns were prepared on titanium Implant model with implants placed at premolar region and at a molar position. Two grooves one at 900 and other at 1800 were made and 20 samples of inlay wax patterns and 20 samples of margin wax patterns were made which were further divided into two subgroups of 10 each of premolar region and molar region respectively Two stage burnout was carried out and casting was done using nickel-chromium alloy. Two points marked at 900 and 1800 were checked at margin level with the help of stereomicroscope and the vertical marginal gap was evaluated. The marginal gap was calculated at 2 points i.e. 900 and 1800. The distance of the line from groove to the outermost margin was calculated at the master die and on all the samples and their differences were recorded. Results: The data collected from all the samples were analyzed using ANOVA and post hoc tests. In intergroup comparison between both the groups, Group 1 recorded more marginal gap (25.40 ± 0.52 μm) than group 2 (19.99 ± 0.39 μm). In intragroup, comparisons between the subgroups, group B (24.13 ± 0.17 μm) recorded more marginal gaps than group A (21.26 ± 0.41 μm). The f value for all the subgroups was calculated as 87.2899 which was significant at p<0.05. Conclusion: Among the materials tested, patterns made of Margin wax proved to have more marginal fit than Patterns made of inlay wax.

Abstract

Aluminium metal matrix composites (AMMCs) have considerable applications in aerospace, automotive and military industries due to their high strength to wear ratio, stiffness, light weight, good wear resistance and improved thermal and electrical properties. Ceramic particles such as Al2O3, SiC are the most widely used materials for reinforcement of aluminium. Boron carbide (B4C) could be an alternative to SiC and Al2O3 due to its high hardness (the third hardest material after diamond and boron nitride). In the present study, an effort has been made to develop and study the mechanical properties such as Tensile strength, Compression strength, hardness and density measurement of Al7050-B4C metal matrix composites. The composites were prepared by stir casting route (liquid metallurgical technique) in which amount of reinforcement is varied from 2-8 wt% in steps of 2 wt%. In case of each prepared composites of Al7050-B4C, the reinforcement particles were pre-heated to a temperature of 5000Cand mixed with Potassium titanium fluoride before adding into the vortex of the molten metal to improve wettability and distribution of B4C particles. The microstructural studies were carried out using scanning electron microscope which shows the uniform distribution of B4C particulates in the matrix alloy. EDS analysis will be carried out to analyze the microstructure and the dispersion of the reinforced particles in the alloy matrix. The tensile strength and compression strength Al7050 and Al7050-B4C were carried out using UTM and hardness test using Brinell hardness tester, which results in increase in tensile strength, compression strength and hardness of the composites as the increase on wt% of B4C, The obtained results were compared with ascast Aluminium Alloy.

Abstract

Buildings built using cold-formed sections as primary members (frames) and secondary members (purlins) offers a viable alternative solutions for wide range applications of social sectors like housing, education etc. Design of cold formed sections has obvious complexity in view of buckling of sections vis-à-vis stress in the compression element, especially in flexure. In this study, using IS801 equations, effective section properties of C section are calculated for wide range of configurations with different b/t ratios for flange subjected to maximum allowable stress. These section properties are used to evolve optimum frame configurations for various wind zones of the country. Study also presents simple design tools and few standard cold formed sections having similar configuration but for thickness to be used for residential or community shelters for different wind zones. A recourse is made to compare the results with similar studies using AISI code

Abstract

The aspects of availability and price fluctuations of crude oil have made attractive the use of biodiesel as a viable alternate fuel for CI engine. Many researchers and industries have studied the effects of biofuel- diesel blends on the performance parameters of CI engine. However, many studies have been carried out in advance countries having excellent roads and traffic conditions, where the CI engines usually operate at optimum levels. In the Indian context, the CI engines, especially in the transport sector, have to operate at varying load conditions and therefore it is important to study and analyze the effect of engine load on engine performance parameters. The present study is an attempt to determine the effects of loading a Kirloskar make 3.6 kW, single-cylinder, four-stroke, CI engine with diesel & biofuel as fuel. In this study, the effect of intake charge dilution with exhaust gases on the power and emission characteristics were investigated. With increase in dilution of fresh air with exhaust gases, CO, HC and NOX considerably decreases. As the percentage of EGR is increased from 0% to 15%, slight decrease in BP and & major decrease in NOX are observed, but HC and CO increases as the percentage of EGR is increased. It appears that the intake air dilution by EGR will cause the reduction in temperature in combustion chamber results in reduction of NOx.

Effects of Functionally Graded Adhesive on Failures of Double Lap Joint Made of Laminated FRP Composites

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 12th April 2018

Ankit A. Sawant | S.V. Nimje

Abstract

The demand of modern industries to use lightweight assemblies has promoted the use of composite materials. Using traditional joining methods to assemble these materials leads to the introduction of stress concentrations which reduce the strength of the assembly. Adhesive bonding technique is used to overcome this limitation. Stress analysis carried out on double lap joint by previous researchers using mono adhesive layer indicates stress concentrations at the ends of the overlap. The present research is done in the view of reducing the stress concentration at the ends and thus increasing the joint strength. The greater adhesive shear strains at the overlap edges necessitate the use of more ductile adhesive at the edges and less ductile adhesive in the middle. This has been achieved by grading the adhesive layer from stiff in the middle to ductile at the ends using smooth and continuous gradation profiles. Three-dimensional finite element analyses are carried out on the double lap joint and the stresses at the various interfacial surfaces have been determined. The onset of failure has been predicted using Tsai-Wu coupled stress failure criterion. The critical location has been found to be present between the main adherent and adhesive layer. The successive numerical simulations carried out using various modulus ratios indicate a considerable reduction in failure index at the critical locations. The results indicate an increase in joint strength using functionally graded adhesive than using mono adhesive layer.

Abstract

In recent days most probably all industrial processes and parameters are controlled by using PLC & SCADA programming. The industrials like Oil refineries, Steel industries, Chemical plants, Shaving products plants. Nitrogen is a corrosive gas and it is usually used in Heat treatment plants. Also, It is used to dilute reagent gases, to increase the yield of some reactions, to decrease the fire or explosion. We generate nitrogen gas by using Pressure swing adsorption principle. Working on this principle depends upon the sequencing of Adsorbing and Desorbing of Carbon molecular sieves by the sequence of tower valves. These Valves are controlled by numerous cam timers, solenoid valves, Actuators and changeover Adsorbing & Desorbing of carbon molecular strainer is depending upon the Opening and closing of PSA valves. So finally Purity of nitrogen is depending upon the multiple cam timers, solenoid valves, Actuators and changeover valves. This is semi-automated. We are developing the PLC & SCADA Programming for this process. This paper describes by adding a Booster after Nitrogen surge vessel to increase pressure and placing the old electromechanical command with the PLC and SCADA. First, it displays the ladder logic that can be implemented to operate the Nitrogen generator plant. Secondly, it exhibits installation of PLC in the plant and factors to be regarded for its installation and operation.

Abstract

During the everyday usage of an automobile, only 10–16% of the fuel energy is used to drive the car—to overcome the resistance from road friction and air drag. A conventional automotive shock absorber dampens suspension movement to produce a controlled action that keeps the tire firmly on the road. This is done by converting the kinetic energy into heat energy, which is then absorbed by the shock’s oil. This is the important loss is the dissipation of vibration energy by shock absorbers in the vehicle suspension under the excitation of road irregularity and vehicle acceleration or deceleration. In this paper we study the concepts of power generating shock absorber which can efficiently recover the vibration energy in a compact space.

Abstract

Fly ash a fine powder thrown out in large quantities from thermal power plants as a waste material, we have used this material in our project. Since its the cheapest material available at Satpura Thermal Power Station, Sarni. The problems associated with fly ash are the large area of land required for disposal and toxicity. Fly ash, being treated as waste and a source of air and water pollution till recent past, is, in fact, a resource material and also proven its worth over a period of time. Fly ash is having the potential for gainful utilization till is put to right use. It has now emerged not only as a resource material but also as an environment savior. Fly ash is also being used in the cement production and precast products as a fill material etc. Ministry of environment and forest had made compulsory to use fly ash for any construction project within 100 km of the power plant. Slope stability is the potential of soil covered slopes to withstand and undergo movement. We followed the analysis to make embankment stable enough to resist against failures and could resist external forces like the earthquake. The composite of soil and fly ash will exhibit the strength as properties of fly ash have proved favorable in the embankment. Fly ash is used as a borrow material to construct fills and embankments. Fly ash has been used in the construction of structural fills and embankments from small fills for road shoulders to large fills for interstate highway embankments. So we proposed slope stability analysis using the composite of soil and fly ash.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 27th November 2017

Vadlamani Praveen Kumar | Mrityunjay, SiddharthAgarwal, Gitimayakar, Sonit Singh

Abstract

The present paper gives an experimental study of the operation of a dual cylinder diesel engine working in dual fuel mode using jatropha oil biodiesel (JOBD) as the pilot fuel and producer gas as the primary fuel. JOBD is produced by esterification and transesterification process catalysed either by acids or bases followed by water wash and heating. Biodiesel require high temperature for ignition, so that is the only reason they are used in dual fuel mode. Utilization of biodiesel in vehicles reduces the excessive use of petroleum fuels and also reduces the emission of soothe particles. They also show positivity towards maintaining the balanced and sustainable growth of our economy. The experimental study shows the variation of emission characteristics of carbon dioxide (CO2). Carbon monoxide (CO), Hydrocarbon (HC), nitrogen oxides (NOx) and smoke opacity with respect to change in load. Along with the emission characteristics fuel consumption is also observed in order to appeal out the savings of the fuel. It has been found that while operating under different biodiesel blends and with varying load (Brake power) the emission levels of HC, CO,NO and smoke opacity have had a considerable reduction while CO2 emissions has increased

B.Prashanth | Swarup Kumar Nayak. [3]C. Manisha

Abstract

The present paper gives an experimental study of twin cylinder diesel engine operated in dual fuel using jatropha oil methyl ester as the pilot fuel and producer gas as primary fuel. Producer gas is produced by the gasification of Babul wood and the jatropha oil is produced by the transesterification process. Global warming and change in the balance of ecosystem is due to the emission of different harmful gases in to the atmosphere. This has led scientists to find an alternative to the present problem and one among them is alternative fuel (Biodiesel). A remarkable growth is observed in the automobile as well as industry sectors and this resulted in the continuous exploitation of fossil fuels. The utilization of biodiesel in the engine reduces the excessive use of petroleum fuels and also reduces the excessive emission of soot particles. Biodiesel is degradable and the production process is simple which makes it easy for everyone to understand. The experimental study shows the variation of emission characteristics of HC, CO, CO2and pilot fuel savings with respect to varying load when the engine is operated in dual fuel mode.

Therefore global interest is generated to find out a substitute for the current pilot fuel. Biodiesel has attracted interest in recent times due to its oxidation characteristics and environmental benefits. Biodiesel obtained from straight vegetable oil through a process known as base catalyze transesterification process. In this process the reversible reaction between the triglyceride of vegetable oil and methanol in presence of the base catalyst (KOH) to produce glycerol and methyl ester. The methyl ester produced in this process is then blended with biodiesel in various proportions before use in a diesel engine. The experimental investigation on the engine performance shows that the Brake power, Brake thermal efficiency and exhaust gas temperature gradually increases with increase in loads. Similarly, the emission analysis with the above test fuels shows that Carbon monoxide, Carbon dioxide and Hydrocarbons increase with increases in load for all test fuels including the pilot fuel and Oxides of nitrogen emission increases with load and is highest for pure biodiesel. From the above experimental results, we may conclude that waste cooking methyl ester can successfully be used in a diesel engine without much engine modifications and be degrading the engine performance and emissions.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Sachin B. Patil | Dr. Bhimlesh Kumar, Dr. Rahul Lodha

Abstract

Quality has become one of the most important consumer decision factors in the selection among competing products and processes. The quality of conformance is how well the product conforms to the specifications required by the design. The quality can be measured in terms of Process Capability defined as the index of which the process is capable of producing mass products with certain specifications. However, for every product there is certain limits for design, manufacturing and aesthetics. The limit of manufacturing for producing accurate dimensional products may called as specification limits. These limits denote the end criteria for the batch production. The approach presented here is to define the meaning of quality and the influence of process capability on batch production. The literature provided for the quality and process capability are useful to study the behavior of the processes under batch production. Certain charts have discussed here to understand the Boring Process

Abstract

As the human population, industrialization and modernization increases day by day. The condition of consumable water becomes miserable. So it becomes our primary objective to get consumable drinking water, with the lowest possible cost, without suffocating the conventional source of energy (like- coal, electricity). In this way solar distillation system (solar still) seems a very promising method to get consumable drinking water with lowest possible cost and without polluting environment. Although the concept of solar distillation is not new, again lot of research has been performed to get the highest possible distilled water from the solar distillation system. To increase the production rate of solar distillation system, an experiment has been performed regarding this; we use already heated water from evacuated tube solar water heating system to the solar distillation system incorporated with the fan powered by solar panel

Abstract

Presently manufacturing industries are facing challenges from difficult-to-machine materials viz. Superalloys, ceramics and composites which require high precision and surface quality thereby increase machining cost. Electrical Discharge Machining (EDM) is a non-traditional machining process that has become a well-established machining option in manufacturing industries throughout the world. The analysis of surface characteristics like surface roughness, microcracks of workpieces shows excellent improvement in machined surface. Carbon nanotubes are generally of two types, single-walled varieties (SWNTs), which have a single cylindrical wall and multi-walled varieties (MWNTs) which have cylinders within cylinders. Carbon nanotubes are one of the most commonly mentioned building blocks of nanotechnology. With one hundred times the tensile strength of steel, thermal conductivity better than all but the purest diamond, and electrical conductivity similar to copper, but with the ability to carry much higher currents, they seem to be a wonder material.

A.Venkatesan | V.Gopal

Abstract

Materials are precious resources. Different methods are employed to protect the material from degradation. Thermal spraying is one of the most effective methods to protect the material from wear, high temperature corrosion, stresses and erosion, thus increasing the life of material in use. Detonation gun spraying is one of the thermal spraying techniques known for providing hard, wear resistant and dense micro structured coatings. In this paper, to increase the Wear Resistance and the Fatigue Strength of Mild Steel and Aluminium alloys, we are going to use Zirconium and Alumina-Titanium powders for Detonation Spray Coating. They are ceramic materials which can withstand high heat and thermal load. They are easily available ceramics and can be coated by detonation spray coating. The materials chosen for coating are Alloy special Steel EN19 and Al A319. The materials are coated with Zirconium powder and Alumina-Titania by Thermal spray detonation method. After coating, the fatigue strength and wear resistance of the material is tested and compared with the results of the base material. The apparatus for wear testing is Drum type abrasion test. The fatigue test is to be done by high cycle push-pull tensile compression fatigue by Cyclic Deformation and Fatigue Crack Formation. The results are to be evaluated and compared. The percentage increase in wear resistance and fatigue strength is to be calculated.

Environmental Management Planning for a Textile Dyeing Industry: A Case Study

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 14th July 2017

Kashmira B Patil | Dr. V. D. Salkar

Abstract

In many nations, textile industries are major contributors in terms of industrial production, employment and economy. The subsequent pollution resulted is in the form of water, air and noise pollution which is very hazardous for health and environment. Increasing responsibilities of a management to comply with progressing environmental legislations has created a need of appropriate Environmental Management Plan (EMP). EMP is an integrated approach for comprehensive monitoring, reducing losses, waste generation and adverse environmental impacts. As textile industries vary substantially as regards raw materials, processes and products, the industry specific EMP is inevitable to conquer the environmental pollution. Attempts are made in the present study to demonstrate systematic formulation of EMP for a typical textile dyeing industry from Ichalkaranji (Maharashtra). The study involves careful consideration of water usage in textile processes, characteristics of waste and subsequently proposing suitable strategies for environmental protection. The significant observations and recommendations made are put forth in the present paper. The effluent is provided with primary treatment by the industry. The secondary treatment is carried out at common effluent treatment plant (CETP) installed by Ichalkaranji Textile Development cluster (ITDC). Primary treatment provided at industry is found to be rather inadequate to meet the expectations of CETP. So, there is a need to upgrade the primary treatment qualitatively. The stack height is also found inadequate, so needs revision as discussed in the paper. The proposed organizational structure of Environment Management Cell and Disaster Management Plan are also presented as part of the EMP. So, the present endeavor would help the industry for sustainable operation as well as future development

Establishing a Diagnostic Technique for Identification of a Problematic Foundation

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 22nd January 2018

Lokesh N Rai | Awtar Narain Mathur

Abstract

Diagnosis of a vibration problem when the machine has been assembled completely is often tedious. In fact there are several rotating components in a motor assembly which may be responsible for high amplitude of vibrations. In addition, any static component can also generate vibrations. When a rotating machine exhibit large vibrations, often the doubt goes to moving components or the bearings. Efforts are carried out to identify a problem in one of these components, but sometimes it may so happen that no fault is identified in rotating parts or bearings and still the vibrations become uncontrollable. This is exactly what happened in a motor in a Nuclear Power Station having 2 machines each of 236 MW rating. In place dynamic balancing was carried out but it did not help. Frequency analysis revealed some looseness in nuts and bolts but controlling them also could not reduce the vibrations. Ultimately, the recently developed technique of phase measurement and analysis was applied and the problem was diagnosed to be that of faulty foundation system. Appropriate corrections were then made and vibrations were brought down to permissible limits. This paper presents the methodology used in establishing the technique for identification of a problematic foundation, which can be used in case of motors, turbines, generators and alternators et

Abstract

Wire Electrical Discharge Machining (WEDM) is a specialized thermo electrical machining process capable of accurately machining parts with varying hardness or complex shapes. Present study outlines the estimation of machining performances in the wire electric discharge machining of HCHCr material using Multiple Regression Analysis (MRA) and Group Method of Data Handling (GMDH) technique. HCHCr material was machined using different process parameters based on Taguchi’s L27 standard orthogonal array. Parameters such as pulse-on time, pulse-off time, current and bed speed were varied. The response variables measured for the analysis are dimensional error, surface roughness and volumetric material removal rate. Machining performances have been compared using sophisticated mathematical models viz., MRA and GMDH. Different GMDH models can be obtained by varying the percentage of data in the training set and the best model can be selected from these, viz., 50%, 62.5% & 75%. The best model is selected from the said percentages of data. Three different criterion functions, viz., Root Mean Square (Regularity or RMS) criterion, Unbiased criterion and Combined criterion were considered for estimation. Estimation and comparison of machining performances were carried out using MRA and GMDH techniques. Estimates from MRA and GMDH were compared and it was observed that GMDH gives better results than MRA.

Estimation and Comparison of Surface Roughness and AE Parameters of P-20 tool steel Material in Wire Electric Discharge Machining using Multiple Regression Analysis and Group Method Data Handling Technique

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 20th February 2018

Prathik Jain S | H V Ravindra, G V Naveen Prakash, G Ugrasen

Abstract

Wire Electrical Discharge Machining (WEDM) is a specialized thermal machining process capable of accurately machining parts with varying hardness or complex shapes, which have sharp edges that are very difficult to be machined by the main stream machining processes. Selection of process parameters for obtaining higher cutting efficiency or accuracy in WEDM is still not fully solved, even with most up-to-date CNC wire EDM machine. It is widely recognised that Acoustic Emission (AE) is gaining ground as a monitoring method for health diagnosis on rotating machinery. The advantage of AE monitoring over vibration monitoring is that the AE monitoring can detect the growth of subsurface cracks whereas the vibration monitoring can detect defects only when they appear on the surface. This study outlines the machining of P-20 tool steel material using L’16 design of experiment. P-20 tool steel material is used for various large-size plastic mould, precision plastic mould, car accessories, home appliances and electronic equipment plastic molds. Each experiment has been performed varying different process parameters like pulse-on, pulse-off, current and bed speed. Among different process parameters, voltage and flush rate were kept constant. Molybdenum wire having diameter of 0.18 mm was used as an electrode. Simple functional relationships between the parameters were plotted to arrive at possible information on surface roughness and AE signals. But these simpler methods of analysis did not provide any information about the status of the work material. Thus, there is a requirement for more sophisticated methods that are capable of integrating information from the multiple sensors. Hence, methods like Multiple Regression Analysis (MRA) and Group Method of Data Handling (GMDH) have been applied for the estimation of surface roughness, AE signal strength, AE absolute energy and AE RMS. The GMDH algorithm is designed to learn the process by training the algorithm with the experimental data. The experimental observations are divided into two sets: the training set and testing set. The training set is used to make the GMDH learn the process and the testing set will check the performance of GMDH. Different models can be obtained by varying the percentage of data in the training set and the best model can be selected from these, viz., 50%, 62.5%, and 75%. The best model is selected from the said percentages of data. The number of variables selected at each layer is usually taken as a fixed number or a constantly increasing number. It is usually given as fractional increase in the number of independent variables present in the previous level. Three different criterion functions, viz., Root Mean Square (Regularity) criterion, Unbiased criterion, and Combined criterion were considered for the estimation. The choice of criterion for node selection is another important parameter for proper modeling. From the results, it was observed that AE parameters and estimated surface roughness values correlated well with GMDH when compare to MRA.

Estimation of Machine Vision and Acoustic Emission Features in Turning Nimonic75 by ANN

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 5th July 2017

Y D Chethan | H V Ravindra, Y T Krishnegowda

Abstract

Turning is an important and widely used manufacturing process in engineering industries. The study of metal removal focuses on the features of tools, work materials, and machining parameter settings. Nickel-based super alloys are widely used in aircraft industry as they are exceptionally thermal resistant and retaining mechanical properties up to 700°C. By virtue of the above they induce tool wear while machining which seriously affect the life of the component, and it is a serious concern, since it is used in critical applications. In order to monitor the tool status in turning process, tool status dependent machine vision and AE features were extracted during machining and an attempt was made to obtain a clear insight of the parameters involved. But these simpler methods of analysis did not provide sufficient information about tool status and hence there was a requirement for more sophisticated method of signal analysis. This paper is the report of an investigation of an approach for machine vision signals estimation in turning for tool status monitoring. Tool status models were defined utilizing feed forward neural networks based on back propagation algorithm. The cutting test data were provided to the designed neural networks in order to train, validate and test them. Several configurations of networks, characterized by different number of hidden layers and number of neurons in the hidden layers, were trained for carrying out the best arrangement for the status parameters prediction, in terms of resulting errors. The input neurons are the investigated parameters (Machining time, AE RMS, AE count and perimeter), in estimating vision features i.e. wear area: perimeter, machining time, AE RMS, AE count are considered as the independent variables and vice versa in order to have the performance well in multi sensory situations. This ANN model could predict the vision and AE features by knowing the input data at time t. Also, this ANN model and multisensory system were coupled for on-line monitoring of the tool status.

Abstract

This paper identifies the technical feasibility of using Pongamia (Honge) oil and Biogas under Dual-fuel mode. This technology can be applied in rural area for electricity generation in developing countries. The use of Honge oil and Biogas is considered as sustainable energy supply, when both are produced locally. The experiment is carried out to study the performance of diesel engine (CI Engine) under dual-fuel mode, which is carried out on 5KW diesel generator set. The esterified honge oil (EHO) blends with diesel and bottled biogas was used for experimentation, and the gas is directly added to inlet air by modifying the induction manifold. The experiment is carried out for varying lamp loads. The engine shows considerably high thermal efficiency for EHO and biogas combination. The mechanical efficiency was improved than diesel biogas operation. One more point noticed that introduction of biogas drastically reduces EHO blends and diesel consumption. The part of paper also describes application of Artificial Neural Network (ANN) to estimate Thermal efficiency and BSFC of the engine, from comparison and observation it clears that ANN estimates close to experimental value when 90% of data is at training set. Estimated Thermal efficiency and BSFC using Artificial Neural Network correlates well with measured value. The mass flow rate, speed temperature, fuel consumption rate and time are used as a input parameters.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 21st July 2017

Harshith H S | Dr. Joel Hemanth

Abstract

- This paper describes the results obtained from fracture toughness tests performed on chilled LM13-Fused SiO2 composite containing dispersoid (size ) content ranging from 3 to 12 wt % varying in steps of 3%. The resulting composites cast in moulds at ambient temperataure containing metallic (copper, Steel, Cast Iron) and non metallic (Silicon Carbide) chills. The effect of strength and fracture toughness for varying chilling rate and dispersoid content was also examined. The strength and fracture toughness tests were carried out in conformance with AFS (American Foundrymen Society) and ASTM (E 399 1990) standards. Results of the investigation reveal that there is good bonding with consistency in the matrix and as the glass content is increased, the strength and fracture toughness increase remarkably and is highly dependent on the location of the casting from where the test specimens are taken. Large particles and the regions of clusters of particles were found to be the locations prone to damage the composite prior to final fracture.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Ramakrishnaiah | Ramunuja Maikam Verma,Bylappa,Ajeya Kumar

Abstract

The physical (density and water absorption) and mechanical (tensile, flexural, impact and hardness) properties of banana empty fruit bunch fiber -glass fiber- oil palm empty fruit bunch particles- reinforced polyester composite were investigated. The natural fibers were extracted and processed locally. Thereafter, the test specimens were prepared using polyester resin with different compositions and prepared in accordance with ASTM standards. The results showed that as the banana fiber content was increased, there was a corresponding decline in the flexural strength. However, increasing the glass fiber content resulted in a corresponding increase in flexural strength. Composite with palm empty fruit bunch OPEBF 5 wt. % banana fiber 10wt% /glass fiber10 (wt.%) produced high impact strength of 55.556J/m2 representing 1568.67% improvement over that of the virgin unsaturated polyester. It was discovered that banana fiber of 15wt% and glass fiber of 5wt% hybrid composite had the highest hardness (3.55HV) representing 136.67% improvement on the hardness of the polyester (1.5HV). It was observed that the hardness of the samples was influenced by increase in banana fiber content in the composite. Thus, banana fiber composite could be considered for applications in areas where high impact strength is a requirement such as in some parts of automobile vehicle.

Abstract

These days, plastics and synthetic fiber composites are growing remarkably due to their wide range of domestic applications. However, it is more evident that the environment is considerably stressed and damaged due to their non degradable plastic and synthetic essence. In recent years, natural fibre composites have gathered much research attention as reinforcing components owing to their affluent mechanical properties. So far, various natural fibres like sisal, bamboo, banana, flax, kenaf and coir were used as reinforcements and more such natural fibers with outstanding properties can be a considerable breakthrough. One such fibre with proven bio-medical properties is Cordia dichotoma where in this work; its fibers were used as reinforcement to fabricate the composite. Hand-layup technique has been used for preparing the specimens with an increasing fiber weight of 5, 10, 15, and 20 gms respectively. They were cut as per the ASTM standards. Further they were tested for Tensile and flexural strengths using Instran Testing Machine (UTM). They depicted a regular trend of an increase in properties with fiber weight of 20grams.Tensile and flexural tests revealed 23.41MPa and 103.48 Mpa of tensile and flexural strengths respectively. Morphology of tensile and flexural specimens was carried out to observe the interfacial bonding using scanning electron microscope (SEM).

Abstract

Fracture is a failure mode due to unstable propagation of a crack due to applied stress. Fracture mechanics provides a methodology for prediction, prevention, and control of fracture in materials, components and structures subjected to static, dynamic, and sustained loads. Fracture mechanics analysis is the basis of damage tolerance design methodology. The objectives of fracture mechanics analysis are determination of (1) Stress intensity factor (K), (2) Energy release rate (G), (3) Path independent integral (J), (4) Crack tip opening displacement (CTOD), and prediction of (1) Mixed mode fracture, (2) Residual strength and (3) Crack growth life. In this paper, Stress Intensity Factor(K) is analysed for a rectangular block containing a surface crack of elliptical profile and subjected to uniform tensile pressure. The stress intensity factor is evaluated using numerical approaches like Displacement Extrapolation method, Extended Finite Element method and Finite Element method. The results obtained from all the above methods are compared with the experimental method available. Using this an efficient approach is identified and has been used for analysing the stress intensity factor of a cryogenic cylinder which is considered as a case study.

Abstract

Exoskeletons are a feature of some of the worlds strongest creatures. An Exoskeleton is the stiff covering on the outside of some creatures like the arthropods like scorpions and crustaceans. Having a hard covering on the outside in the form of an exoskeleton is a great defence against external threats. Just like the natural exoskeletons protect some of these animals soft, inner organs from injury, artificially powered exoskeletons have also been incorporated into human lives to provide an excellent survival strategy. An exoskeleton is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a Human. In usage, some of the larger kinds of exoskeletons are known as "shells". Examples of exoskeleton animals include insects such as grasshoppers and cockroaches, and crustaceans such as crabs and lobsters, snails, clams, tusk shells, chitons and nautilus, are also exoskeletons.

Experimental Analysis of a Flat Plat Liquid Desiccant Dehumidification System

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 5th February 2018

Rajneesh Kaushal | 

Abstract

The continuously increasing energy demand in building space cooling and depleting conventional energy resources have provoked the need for generating renewable and sustainable energy technologies. Pre-eminent among the air conditioning technologies are absorption cooling that works on the low grade energy which is mostly delivered by solar energy. Liquid desiccant dehumidification technologies are the most optimistic option because of their lower regeneration temperature, higher coefficient of performance and ability to be used during night hours. But problems like desiccant carryover, process air pressure drop and incomplete wetted walls needs to be further investigations. The desiccant system investigated in the present study includes a flat plate energy exchanger for mass and heat transfer between process air and desiccant solution. It imparts high contact surface area and minimises the air pressure drop and carryover of desiccant droplets as there is a film contact between air and desiccant instead of direct intermixing which is associated with spray tower and packed bed dehumidifiers. It also provides a complete film over an entire surface of the flat plate which is the limitation of falling film absorbers. The diluted desiccant is heated into a heater tank consists of a heating coil and reactivated in the regenerator. The system comprises of an absorber, a regenerator, a solution heat exchanger to precool and preheat the solution and a cooling tower and a set of solution pumps. Calcium chloride was used as a desiccant material with 40 % by wt. concentration. Experiments were conducted by varying concentration of the desiccant solution and process air flow rates. Performance of the dehumidification system is represented in terms of dehumidification and regeneration effectiveness and moisture absorption rates.

Abstract

The study presents the evaluation of steel slag in concrete compared to natural aggregate in concrete. Steel slag is obtained glass like product left over after the desired material has been smelted from its raw ore. It is the mixture of metal oxides and silicon di-oxides. Steel slag was selected due its characteristics which are almost similar to conventional aggregates. There are many grades of steel that can be produced, and the properties of the steel slag can change significantly with each grade. Grades of steel can be classified as high, medium, and low, depending on the carbon content of the steel. The compressive strength results obtained for specimen with steel slag was almost same as that of normal concrete specimen. Since the Steel slag is the by-product of steel industries, thus it is easily available and cheap. The main purpose of using steel slag was to save the natural aggregate and hence using the so called waste product and recycling it instead of dumping it in the environment. The study done is on M40 grade concrete with 25%, 50%, 75% and 100% replacement of conventional aggregates with steel slag and the maximum compressive strength is achieved.

Abstract

- Understanding the fluid path lines using carbon black coating method on target plate in Jet impingement process provides information about the interaction between the jets in the array which plays an important role in the cooling performance. Experimental visualization of flow structure on target plate is observed in collision of wall jets after impingement producing complex flow field. The array of jet consists of three impinging jets at equidistant from the central jet. Jet-to-plate spacing (H) to hydraulic diameter of jet (d) ratio varied from 2 to 4 and jets Reynolds number is varied from 1742 to 3649. Computationally obtained flow structure of interacting jets and effects of varying H/d ratio and Reynolds number on fluid flow, heat transfer and pressure distribution are compared with experimental data. Pressure distribution over the target plate depends on Reynolds number and H/d ratio. Convective heat transfer increases with increase in Reynolds number and decreases with increase in jet to plate spacing (H).

Abstract

The rehabilitation of existing Reinforced Concrete (RC) structures becomes necessary due to defects in design/construction, ageing, damage due to earthquake/fire, corrosion of reinforcing steel, demand in the increased service loads and revisions in the design guidelines. Rehabilitation of RC structures can be done in various ways such as repairing, retrofitting & strengthening. Fiber Reinforced Polymers (FRP) has emerged as the promising material for rehabilitation of deficient RC structures and accepted by construction industry due to ease of application. Beams are flexural elements in RC framed structures. From the previous researchers, it is revealed that most of the work is done to study the flexural behavior of RC beam deficient in flexure by applying GFRP laminates for full length on tension face of the beam or U-wrapping. In this way, the GFRP laminates applied on shear zone cannot be efficiently utilized for flexure strengthening. In the present research work, the effect of varying length of GFRP laminate on flexural behavior of deficient RC beams was investigated. The investigation was done on beams with GFRP laminates applied on tension side and subjected to three-point static loading system. Finite Element Analysis (FEA) of the similar specimens were carried out using ANSYS. The results obtained from ANSYS were in good agreement with the experimental investigation. From the test results, it was observed that flexural capacity of RC beams varied with the length of GFRP laminate applied.

Experimental Investigation in Turning Wrought Alloy (VT-20)

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 11th April 2018

Vaibhav Joshi | S.C Borse

Abstract

Turning operation is one of the most basic machining processes. That is, the part is rotated while a single point cutting tool is moved parallel to the axis of rotation. Hard turning is becoming more popular for machining hardened steels as it has several benefits over grinding. The hard Turning process is defined as machining metals with the hardness greater than 45 HRC. CNMG 120408 is the dominant tool material for hard turning applications due to its high hardness, high wear resistance, and high thermal stability. The temperature generated in hard turning is Substantially higher when compared to conventional machining as the cutting speeds employed in hard turning are higher and dry cutting environment is usually employed.[1] Hard turning is a high-speed machining phenomenon with surface speeds going normally as high as 250 m/min, sometimes even more than this. So the machine tool capabilities should include high machine tool rigidity, high surface speed, and constant surface speed for a profile to be finished and high accuracy with a required surface finish.[2].

Abstract

One of the greatest challenges of the 21st century is to solve the problem of depletion of fossil economy. In this era our environment is badly affected by the pollution of fossil fuel which led to introduce an alternative fuel for compression ignition engines. Biodiesel is receiving more attention as an alternate fuel to the diesel engine with no or fewer modification. Previous studies reported that the use of biodiesel in compression ignition engines leads to the reduction in Hydrocarbon (HC), Carbon Monoxide (CO) & PM emissions accompanying with increase in fuel consumption & Nitrogen Oxide (NOX). Exhaust Gas Recirculation (EGR) is one of the methods to reduce the NOX emitted by C.I. engines. NOX is formed in condition of higher flame temperature and high oxygen availability which is greatly reduced by the process of EGR.Experiments were conducted on a single cylinder, four strokes, Variable Compression Ratio (VCR), water cooled diesel engine at full load with provision for EGR. In this paper, the comparison of performance and emission characteristics on the C.I. engine when it is fueled with biodiesel and diesel with 0%, 5% and 10%EGR are shown. Experimentally has been proved that, 10% EGR with biodiesel blend have minimized NOX and improved performance

Shaik Ismail Basha | S Gopi, S. Ramalinga Reddy

Abstract

Metal Matrix Composites (MMCs) have evoked a keen interest in recent times for potential applications in aerospace and automotive industries owing to their superior strength to weight ratio and high temperature resistance. To achieve these objectives two step-mixing method of stir casting technique has been adopted and subsequent property analysis has been made. Aluminum (Al 2024 ) and SiC (150 μm) has been chosen as matrix and reinforcement material respectively. The present study was aimed at evaluating the physical properties of Aluminum in the presence of silicon carbide at varying compositions. Consequen tly aluminum metal matrix composite combines the strength of the reinforcement with the toughness of the matrix to achieve a combination of desirable properties not available in any single conventional material. The compositions were added up to the ultimate level and stir casting method was used for the fabrication of aluminum metal matrix composites. Experiments have been conducted by varying weight fraction of SiC (5%, 10%, 15%, 20%, 25%), while keeping all other parameters constant. The results were evaluated by Tensile Test, Rockwell Hardness Test, Charpy Impact Test (including micro-structure), Compression Test and Heat Treatment In terms of a metal-matrix composite, an Aluminum 2024 alloy as the matrix and silicon carbide as the reinforcement is considered to be an excellent structural material used in both the aeronautic/aerospace industry and also the automotive industry. This is due to its high strength-to-weight ratio and its high thermal conductivity.

Experimental Investigation on Concrete Incorporating Metakaolin and Polyproplyne Fiber

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 16th May 2018

Kajal Bhardwaj | Aanchana sharma

Abstract

Concrete is the most versatile and important building material. The main concern in today’s era is that its manufacturing as well as overuse in the construction sector makes our environment polluted. Since we know that when cement reacts with water it exhibits cement hydration reaction which is generally exothermic in nature and has other repercussions also.. The major drawback of using excess cement is its manufacturing as it is very hazardous and evolves the green house gas carbon dioxide which is very toxic in nature. To overcome these problems, the use of Supplementary Cementing Material like metakaolin, rice husk ash, blast furnance slag, Fly ash and silica fume are some pozzolanic materials which itself doesn’t contribute anything as these are probably the waste product but when get merged with cement shows excellent bond strength and makes concrete less permeable. It also makes the concrete eco friendly and more economical. Experimental investigation has been carried out at M-25 grade. Fibres also enhances the fresh and hardened properties of concrete. It provides protection against micro cracks and makes the overall matrix strong by reducing cracks. This paper deals with the fresh and hardened properties of concrete with partial substitution of binding material known as cement by metakaolin and incorporation of polypropylene fiber at constant 0.3% by mass of cement. The concrete mixes were prepared by replacing Ordinary Portland Cement 43 with 0%, 5%, 10%, 15% and 20% of metakaolin and by adding polypropylene fiber at 0.3% by mass of cement. The test results will taken for Compressive, Split Tensile Strength and Flexural Strength and it would be observe that metakaolin as a binder will react with cement at early stage because of its fine particle size will make the concrete less permeable and addition of polypropylene fiber also fills the micro cracks then the desired results will achieved. Cubes, Cylinders and Beams will be casted for 7, 14 and 28 days .Superplasticizer will also be used as the both metakaolin and polypropylene fiber will make the concrete unworkable. In order to maintain the workability critera the dosage is fixed at 0.2%. The overall results shows this combination will provide us excellent results.

Experimental Investigation on Conventional Concrete by partially replacing e-Waste as A Course Aggregate

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 23rd January 2018

M.Christina Miracle | 

Abstract

The problem of e-waste has become an immediate and long term concern as its unregulated accumulation and recycling can lead to major environmental problems endangering human health. Central Pollution Control Board (CPCB) estimated India’s e-waste at 1.47 lakh tones. Efforts have been made in the concrete industry to use non-biodegradable components of E-waste as a partial replacement of the coarse or fine aggregates. Use of these materials not only helps in getting them utilized in cement, concrete and other construction materials, it helps in reducing the cost of cement and concrete manufacturing, but also has numerous indirect benefits such as reduction in landfill cost, saving in energy, and protecting the environment from possible pollution effects. It could be worth experimenting to use E-plastic in concrete to overcome the dual issue of shortage of raw material and safe disposal of leftover plastic to the environment. An experimental study is made on the utilization of E-waste particles as coarse aggregates in concrete with percentage replacement ranging from 0 % to 20% on the strength criteria of M25 Concrete. Compressive strength, Tensile strength and Flexural strength of Concrete with and without E-waste as aggregates is carried out. The feasibility of utilizing E-plastic particles as partial replacement of coarse aggregate is experimentally investigated.

Abstract

The CI engines fuelled with diesel plays a very vital role in Industrialization and transportation sectors. However, the depletion of petroleum products isincreasing day to day. Due to high emissions from the petroleum products there is a strict regulations lay down by the government to the engine manufactures to save the environment from the pollution.Hence the researchers are in the processes of identifying a suitable alternate fuel i.e.biofuelssuch as Jatropha oil, Pongamia oil, Rice bane oil, Corn oil, Neem oil etc. Among all jatropha is considered to be the best replacement because these plants can grow in any environmental conditions and the properties are also nearer to diesel. With minor changes in the diesel engine, Jatropha biodiesel can be directly replaced with diesel. But one of the major drawbacks of Jatropha biodiesel are its flow characteristics and the viscosity of the fuel. In the present work to overcome this, nano additive (Aluminum oxide) is added to the biodiesel which enhances the properties of the fuel. The performance and emissions of diesel engine is experimentally investigatedwith biodiesel 20% by volume (B20) by using the nano additive 50 ppm, 100 ppm and 150 ppm. The performance of the engine depends on the formation of homogeneous mixture and turbulence inside the combustion chamber. Hence in the current work six number of Rhombus grooves are created on the piston crown to enhance turbulence in the chamber and results in the enhance of performance and reduction of the engine emissions. Among all blends the B20 biodiesel with 100 ppm nano additive showed better performance compare to diesel

Abstract

Concrete is a composite material composed of cement, fine aggregates, coarse aggregates and water. Now a day’s construction cost is very high with conventional material due to unavailability of natural materials. This problem can be solved by total replacement of concrete with the different material which is not convenient in terms of required properties. Due to this limitation of unavailability of material which plays the vital role of concrete we have the only choice of partial replacement of concrete ingredients by waste material. In this project, an attempt is made to find the variation in strength properties of concrete on partial replacement of fine aggregate and coarse aggregate by iron ore tailing (IOT)and rubber chips respectively. Experiments were conducted to determine the suitability of rubber chips and IOT as coarse aggregates and fine aggregates respectively for concrete. Compression, Split tensile and Flexure test were carried out for different percentage of rubber chips and IOT for 3%, 5%, 6%, 9%, 10%, 20% and 5%, 10%, 12%, 20%, 24%, 30%, 36% respectively. The results are convenient up to 50% usage of Rubber Chips and IOT

Abstract

The construction of engineering structures on fine grained soil is a challenging task and therefore considered as one of the biggest concern in geotechnical engineering. As the methods used conventionally were very uneconomical and time consuming, there is an urgent need for development of new techniques to satisfy the performance and economical criteria, which enhances the geotechnical properties of soil. It is necessary to adopt safer, economically feasible, environmentally sound and cost effective materials to improve geotechnical properties of Kuttanad clay, by utilizing stabilizers such as Metakaolin (Traditional stabilizer), Terrazyme (Non-traditional stabilizer) and Crumb Rubber Powder (By-product stabilizer). From the experimental investigation it is found that 6% of Metakaolin, 200ml/2m3 of Terrazyme and 10% of Crumb Rubber Powder are the optimum values for improving the geotechnical properties of Kuttanad clay after 14 days of curing period. In the present study an attempt is made to investigate the combined effect of optimum values of these three stabilizers on plasticity, shear strength and consolidation characteristics of Kuttanad clay by conducting Atterberg Limits test , Triaxial Compression test and One Dimensional Consolidation test respectively. The test results indicated that Kuttanad clay treated with a combination of 6% of Metakaolin, 200ml/2m3 of Terrazyme and 10% of Crumb Rubber Powder showed improvement in shear strength behaviour, reduced plasticity and consolidation characteristics after 14 days of curing period when compared to untreated Kuttanad clay

Rajasekhar Sivapuram | Hariprasada Reddy Yedula

Abstract

The emphasis of recent research works in the area of composite materials has been more on improving mechanical properties like tensile strength, micro hardness and wear resistance, fatigue properties etc. The reason is that the desired mechanical properties were not obtained by the ordinary engineering materials. In the present days, significant demand for materials with good wear resistance has been there in automotive, aerospace and military applications. In the present research work, the wear rate of Al6061/SiC metal matrix composite (MMC) has been enhanced by reinforcing Zirconium (Zr) particles to the molten Al6061/SiC metal matrix composites (MMC) by stir casting technique. The wear rate was tested using pin on disk wear tester. An effort has been made to blend 2% of Zr with Al6061 alloy by varying Sic in 10, 15 and 20%. The wear resistance of Al6061/SiC has been improved significantly due to the uniform distribution of Zr particles in the matrix.

Experimental Study of Biogas and Bio-Manure Using Thermophilic Digestion of Different Substrates

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 3rd February 2018

Rajneesh Kaushal | 

Abstract

Experiments have been conducted to determine the augmentation of nutritional values (organic carbon, nitrogen, potassium and phosphorous) of bio-manure. The main substrates have been taken as wheat husk; paddy straw; dairy waste; poultry waste; municipal solid waste and kitchen waste. The substrates have been digested under thermophilic conditions (55 °C). The results show an enhancement in nutritional values in bio-manure where poultry waste has been found to be the best amongst the mentioned substrates. The increase in temperature results in lower retention time and thus reduces the loss of nutrients. The experimental results also show that the intermixing of crop residues with animal waste reduces the quality of bio-manure.

Abstract

In construction, Industry Rising Cost of Construction Material is the Great factor. The price of building material are rising day by day, therefore, there is the most priority of all human beings encourage or research on the sustainable material will help to use such waste material as a construction material with less cost and safety of the structure. The coarse aggregate is the main constituent of test results. The use of coconut shell can also help the prevention of the environment. The paper aims at analyzing the compressive strength of concrete (M20-1:1.5:3) produced using a coconut shell as a substitute for conventional coarse aggregate with 5%, 10%, 15 %, 20% partial replacement. Three sample cubes are prepared for M20 grade concrete mix for each case another aim of this paper is to spread awareness about use of coconut shell as construction material in civil engineering Concrete is most widely used building material in the world, as well as the largest user of natural resources with annual consumption of 12.6 billion tons. Basically, it consists of aggregates which are bonded together by cement and water. The major part of concrete beside the cement is the aggregate. Aggregate includes sand and crushed stone / Gravel. Use of these conventional materials in concrete is likely to deplete the resources unless there is a suitable substitute. Rubber which is generated in large quantities as waste does not have useful disposal till now. But rubber is found to possess properties that are required for viable replacement of fine aggregate in concrete. Hence we in this project have aimed to study the effectiveness of rubber as a substitute for fine aggregate and utilize the crumb rubber tires in concrete, to minimize global warming.

Revathi.V | Bhuvaneswari.D, Thiyagu.K

Abstract

In the present study, an attempt has been made to investigate the flexural behaviour of chemically activated high volume fly ash concrete (AHVFAC) with crushed sand as the fine aggregate. Three series of mix proportions were made with different cement content. In each series, the optimum percentage of fly ash to replace cement was determined based on the compressive strength of high volume fly ash concrete (HVFAC). NaOH was used as an activator to boost up the strength of HVFAC at an earlier age. Flexural behaviour like load, defection, ductility, stiffness and energy absorption was studied and the results are compared with control beam and HVFAC beam. The test results indicate that the flexural behaviour of AHVFAC has a significant spectacle over HVFAC

Elavarasi. V | Niveditha B R, Shanta S Shastrimath, Ratna R Sunagar

Abstract

Infrastructure is a major sector that propels the overall development of the Indian economy. For good foundation and pavement, soil plays an important role. Expansive soils like black cotton soil always create problems in the foundation. To make the soil to be strong the addition of waste plastic to the soil will be an innovative technique for more stabilization. Soil stabilization is a process which improves the physical properties of the soil, such as increasing shear strength, bearing capacity etc.. which can be done by the use of controlled compaction or addition of suitable admixture like waste plastic. Plastic wastes have become one of the major problems of the world. Due to which we are facing environmental problems. This new technique of soil stabilization can be effectively used to meet the challenges of the society, to reduce the quantity of waste and to produce useful material from the non-useful material. The basic properties of the soil such as liquid limit, plastic limit, shrinkage limit, standard Proctor test, California bearing ratio (CBR), unconfined compressive(UCC) strength were considered. The replacement of the soil by waste plastic was carried out in four stages of 1%, 2%, 3% and 4%. Then with the replacement of plastic tests such as standard Proctor test, California bearing(CBR) test, unconfined compression(UCC) test were studied. A comparison made between the black cotton soil and black cotton soil with the replacement of plastic by various percentages

Experiments on Vortex Rings: Interaction with Circular Surfaces

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 5th July 2017

Ijas Hussain | T J Sarvoththama Jothi

Abstract

Vortex rings can be easily produced in the laboratory by pushing a definite column of fluid into a tank containing stationary fluid at a certain velocity. The velocity of a single vortex ring is reducing up on its propagation and diameter is increasing due to the conservation of momentum. The Reynolds number has no influence in the ring diameter and it is depending on stroke ratio only but Reynolds number effecting inversely to the core diameter of the vortex ring. Interaction of vortex rings with cylinders shows cut and reconnection of vortex rings for small diameter cylinders. The interaction produces a pair of secondary vortices having opposite vorticity and reduces the diameter of the primary ring. The interaction with higher diameter cylinders causes the ring to become turbulent and no such observations as other are visible.

Extraction of Value Added Product From Waste Aluminium Dross

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Meet Rajeshkumar La lakiya | Pranab Das

Abstract

It is reported that the aluminium dross generated in aluminium industry is about 5 million tons in the world, but only half can be processed to recover aluminium from aluminium dross. India is expanding its aluminium scrap recycling industry, whose production capacity is at least 1.2 million tons per year. Aluminium production capacity in India is more than 1 million tons per year. In the next five years, India aluminium scrap recycling capacity and primary aluminium production capacity will be doubled. For primary aluminium industry, the aluminium loss is about 1-2%, which is more than 15,000.00 tons aluminium loss each year in the form of dross. Application of dross in ceramic industry is a novel and useful concept because dross contains more than 50% alumina. In the present work alumina was recovered from dross by both acid leaching (sulphuric acid and hydrochloric acid) and alkali addition (sodium hydroxide). The precursor materials were calcined at temperatures ranging between 900-1000°C resulting in the production of different varieties of alumina. Dependent on different acid addition, the generated alumina showed variable morphology under SEM studies. In a separate study the dross was chemically treated to remove undesirable impurities and its application as refractory lining material in furnaces is being investigated.

Abstract

Agriculture is the backbone of India. In rural areas, spraying pesticides is done by hand spray or fuel (petrol/kerosene) sprayers. Sprayers are mechanical devices that are specifically designed to spray liquids quickly and easily. They come in a number of different varieties. These require manual operation/fossil fuel for its operation. To address these issues, a novel protocol is developed viz. Pulverized Agro Sprayer is an innovative product developed for rural applications. The knapsack sprayers, generally used by farmers for spraying pesticides, involve continuous pumping by one hand while holding the sprayer with the other. The whole process of spraying is very tiresome and also leads to hand, back and neck pains by prolonged use, for any scale of operation, with heavy backload. The knapsack sprayers require a lot of time to cover the bigger spraying operations, which increase the cost of spraying as well as the hazard of pesticide mist getting into the eyes. Manual labour has also become scarce due to the migration of farm laborers towards cities. Other options, like tractor mounted sprayers, are too expensive and not of much use in small holdings. Since the bicycle wheel requires less space to move, it can be used in a more versatile manner as compared to power sprayers that are mounted on tractors. A labour saving device, it can be used to spray one acre of land in 45 minutes, thus covering more area compared to manual spraying. It serves the dual function of a sprayer as well as a bicycle

Abstract

This paper gives us an idea of the parameters affecting the anaerobic digestion of food waste on the environment. This will implant seeds of enhanced perception on how biogas can be generated from an inevitable type of waste produced across all cities. Biomass includes organic as well as inorganic waste which may consist of leftovers, kitchen(cooking) waste, cattle feed, industrial waste, slaughterhouse waste, mediwaste etc. Due to the high organic content of food waste, and animal manure anaerobic digestion plays a key role as the micro-organisms act as a catalyst in breaking down the complex organic molecules into biodegradable components in the absence of oxygen. The gas is further processed to generate electricity and it is also used as transportation fuel. This paper summarizes all the important factors that are to be considered for the efficient digestion of the waste like the optimum PH range catalyst required and temperature. Important points like loading rate, retention time and also a composition of the waste material are also taken into consideration.

Study revealed that customers are quite satisfied with provided service whereas, image criteria has relatively low satisfaction index. Architects are not satisfied with the offered cost. Nevertheless, there are no critical satisfaction dimensions requiring immediate improvement efforts. However, if company wishes to create additional advantages against competition, the criteria with the lowest satisfaction index should be improved.

Failure Analysis of Functionally Graded Adhesively Bonded Tubular Joint under Combination of Axial and Torsional Load

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 12th April 2018

Davinder Kumar | S.V. Nimje

Abstract

This research deals with finite element based simulation of a functionally graded adhesively bonded tubular joint under combined axial and torsional loading. The tubes are made of Gr/E (T300/934) laminated FRP composites. The research carried out in past indicate high-stress concentration at both ends of overlap. By employing a modulus graded adhesive along the bond line the stress concentration at the ends of overlap can be reduced. This will result in significant increase in strength and lifespan of the adhesively bonded joint. The material gradation of the adhesive along the bond line is achieved by suitable smooth and continuous function profiles with varied modulus ratios. The out-of-plane shear stress and peel stress values have been calculated along the interfacial surfaces of the bond line of the tubular joint. Failure indices have been calculated by using Tsai-Wu coupled stress criterion to predict the failures onset location The critical location has been identified to be between the outer tube and adhesive layer near the loaded end. Results show the significant reduction in the value of failure index at the critical location thus increasing the joint strength and delayed failure onset location with functionally graded adhesive.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 22nd January 2018

Puneetha B | Dr. Narasimhe Gowda

Abstract

The crankshaft of the engine is a most critical part in the engine as it is a heavy structure with complicated geometry. During working due to repetitive bending and shear stresses are usual stresses induced in the crankshaft, which are solely responsible for the crankshaft failure by fatigue. Thus, the assessment of the fatigue strength and life evaluation of the crankshaft assumes a vital part in the design and development of the crankshaft, taking into account of its safety and reliability during the operation. The Pulsar 180 DTS-i engine is considered for analysis which is made up of forged alloy steel 41Cr4Mo[1]. However, the analysis is also carried out by changing the material grey cast iron SAE J431 G2500 to compare the results. The static strength and fatigue failure criteria of the crankshaft are predicted analytically using S-N approach and modified Goodman theory. The 3D geometric model of crankshaft is created by reverse engineering. The FE model of the crankshaft is then developed using ANSYS Workbench. The investigation of the static structural strength and fatigue life is done utilizing ANSYS Workbench desktop software code and are validated with analytical solutions. Fatigue lives of the crankshaft for both forged alloy steel and grey cast iron are predicted based Von-Mises theory (Distortion Energy theory) and Maximum Principal Stress theory and are compared. Also the variation of fatigue lives of both forged alloy steel and grey cast iron crankshafts with different values of mean stress are predicted and compared. The evaluated results are graphically presented and discussed. There was a close agreement between the results in the Von-Mises stress obtained by analytical and FEA, which was 258 MPa by the analytical calculations and 248.11 MPa from the FE analysis and maximum stress obtained by both analytical and FE analysis were less than the ultimate tensile strength 1020 MPa of the material AISI 4140 alloy steel. The fatigue life of the forged alloy steel Crankshaft is 66% higher than the grey cast iron Crankshaft. And also the fatigue life increases with increase in the value of mean stress

Abstract

The complex three-dimensional geometry and tooling design of precision propeller components by forging technology is impeded by numerous barriers to date. Cold forging, an incremental metal forming process, has great potential to improve the current situation owing to its flexibility and lower tool load requirement. Manufacture of autonomous under water (AUV) propeller owing to complex hubs and blade design poses challenges to researchers who aim to increase thrust. The proposed work investigates cold forging process adopted to produce propeller hubs that involve flash and under-fill as impending problems that can be efficiently solved by proper design and optimization of pre-form. The 3D rigid-plastic finite element (FE) model of cold forging of AA7075 alloy propeller front and back hub was developed under SOLIDWORKS and AFDEX-3D 2014SP0 platform. Four FE modeling approaches have been proposed and simulated by finite element and have been successful in understanding of metal flow, work optimization and die stress in forming process. The AA7075 pre-form with AISI D2 die material for front and back hub considering four pre-forms of various dimensions were investigated for minimization of flash and under-fill. The reported work exposed that pre-form geometry had an important role to play in deciding the dimensional accuracy of the cold formed hubs. The numerical simulations provided interesting results for the optimization of front and back hub geometry that can provide input for experimentation.

Feasibility studies on Fibrous Self Curing Concrete Using Polypropylene Fibre

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 19th March 2018

Vivek Kumar C | Mitta Rakesh, Dr.M.Palanisamy

Abstract

Today Water is the most required substance in the era. In common, Curing of concrete is maintaining moisture in the concrete during early ages specifically within 28 days of placing concrete, to develop desired properties. Proper curing of concrete is essential to obtain maximum durability, especially if the concrete is exposed to serve conditions where the surface will be subjected to excessive wear, aggressive solutions and severe environmental conditions. Poor curing practices adversely affect the desirable properties of concrete which make a major impact on the permeability of a given concrete. Unexpected shrinkage and temperature cracks can reduce the strength, durability and serviceability of the concrete. The surface zone will be seriously weakened by increased permeability due to poor curing. The development of concrete shrinkage is proportional to the rate of moisture loss in concrete. When concrete is properly cured, water retained in concrete would help continuous hydration and development of enough tensile strength to resist contraction stresses. The continuous development of strength reduces shrinkage and initial cracks or micro-cracks. As a part of this investigation of Fibrous Self Curing Concrete, proportion and addition of Polypropylene Fibre resulted in the formation of microcracks in order to reduce the autogenous shrinkage and improvement of durability.

Abstract

Earthquake vibrations can be controlled by using various types of energy dissipating devices such as Dampers, Bracings, Base isolation etc. Dampers are the energy dissipating devices used in the structure, so as to control vibrations in structure resulting into reduction of the violent earthquake motions transmission into the structure. A magnetic levitation type seismic isolation device composed of permanent magnets can theoretically remove horizontal vibration completely. Bracings are provided so that no twisting is induced in the building owing to unsymmetrical stiffness in plan of the structure. At preliminary stage, the bracing system analysis using competent software to have the idea about the behaviour of structure over seismic forces under earthquake condition. Various important parameters are to be considered while having the analysis of the structure with provision of bracings. The same analysis is to be done using hybrid dampers along with levitation force. Various energy dissipating devices are used to reduce the effect of earthquake on structure but it can only reduce effect up to some extent .This facilitates the need for implementation of additional techniques for a better behaviour and stiffness of the structure. This paper enlightensthe technique to reduce the effect of earthquake using various energy dissipating devices along with repulsive force by using a pair of magnet to levitate the structural joints such as column-beam and study the improvement in performance of structure.

Field Investigation on Wall Facing Deformation of Mechanically Stabilized Earth (MSE) Walls Constructed using Cement Modified Marginal Soil with Built-In Facing

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 21st September 2017

S. Goverdhan Reddy | G. V. Praveen

Abstract

It appears that the reasonable way of providing a realistic approach for Mechanically Stabilized Earth (MSE) walls is to construct model walls in the field and study their performance at failure. Hence, it was decided to study the behaviour of model MSE walls constructed using conventional (standard) backfill and marginal soils. This study was undertaken to investigate the mechanism, qualitative behaviour and potential benefits of using cement modified marginal backfill soils under cyclic loading. A field study was undertaken to evaluate the performance of model non–woven geotextile reinforced MSE walls constructed using locally available marginal backfill soils without and with cement modification. In the present study, an attempt was made to make a built–in soil cement facing out of same backfill soil with extended reinforcement into it, which is folded back within the lift thickness. As this type of built–in facing that does not involve the connection problems and tried as an alternative to conventional facing panels. The facing deformations were measured using dial gauges during load testing. The load testing was continued until failure of the respective walls was reached.

Finite Element Analysis and Cost Effective Design for Roll Over Protection Structure (ROPS) of Soil Compactor

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 27th October 2017

Vishnu P | Manjunath A R, H S Kumaraswamy

Abstract

Roll over protection structures (ROPS) are intended to protect operators of heavy equipment and are important elements found on different types of machines used in OEMs. Their use is intended to reduce the possibility of operators (who are wearing seat belt) from being crushed if the machine they are operating rolls over. Design of ROPS should cater to force and energy absorption under lateral, longitudinal and vertical loading conditions. The lateral force requirements and the limitations on deflection are intended to assure that ROPS will penetrate the soil and provide a braking action to the roll. Loading requirement of ROPS is also intended to assure that the deflection encountered by the cabin does not enter the deflection limiting volume (DLV) which is defined as orthogonal approximation of a large operator in a normal seated position. The forces applied in the analysis were calculated as per ISO 3471-2008 ROPS and deflection limiting volume was defined as per SAE J397. The new cost effective design calls for repetition of this process again. This paper presents optimization of ROPS using Finite element analysis by considering energy and load conditions of existing structure and to compare the test results with ISO 3471:2008 ROPS.

Abstract

Floods are plausibly the most revenant, far-flung, disastrous, and frequent natural hazards of the world. India is one of the worst flood-affected countries. The problem of flood in the Indian state called Odisha is well known and every year it becomes a recurring problem to the entire region. This paper is centred towards the Subarnarekha River which is an inter-state river and at the South of Dantan it enters the Balasore district and finally falls into the Bay of Bengal near Kirtania, Odisha. However, it is also among the most susceptible areas in India which are prone to flooding. Flood forecasting & flood warning, flood hazard mapping and flood risk zoning are quite effective non-structural procedures in managing floods that decreases the risks and disasters floods may cause. This study introduces the parameterization of hydrologic modelling for simulation of runoff and Arc GIS software for mapping. Various analysis of hydrological data has been done to look for the rainfall and runoff behaviour in Subarnarekha Basin and their cross-correlation. With the help of GIS, various maps like digital elevation map, flow accumulation map and land use/land cover map have been generated for further modelling.

Flow Dynamics around Tandem Cylinders with Different Longitudinal Gaps

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 10th April 2018

Deep Pandya | Atal Harichandan

Abstract

Dynamics of flow around three circular cylinders in the tandem arrangement has been investigated. Finite volume method has been employed to perform the simulations with high accuracy at Reynolds numbers Re = 100 and Re = 200. A consistent flux reconstruction scheme is considered for the explicit calculation of the primitive variables in flow domain. Due to the complexity of flow geometry, unstructured grids with triangular cells are employed for numerical simulations. The influence of longitudinal gaps (L = 2D and L = 3D) between cylinders upon flow characteristics are estimated. Streamlines and vorticity contours along with a periodic variation of lift and drag coefficients are discussed for each cylinder in the tandem configuration. The downstream cylinder in the configuration experiences very large unsteady forces that can give rise to wake-induced flutter. Also, with an increase in the longitudinal gap, flow separation or reattachment of the shear layer from the upstream cylinder to the immediate downstream cylinder are not observed. In the tandem arrangement of cylinders, the flow field behind the downstream cylinder develops from the steady state into an unsteady state as Reynolds number increases.

Generation of Electricity by OSMOSIS

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 21st December 2017

Aruna Shanbhog | Anusha.R, Akash.V.R, Harshitha.S, Madhuri.S

Abstract

We can't continue using several of our energy sources from where we gain energy today. For example, fossil fuels contaminate our environment and we are also running out of them. It is, therefore, necessary to find other ways of producing energy. This paper focuses on one of those alternatives; osmotic energy. Osmosis means passage of water from a region of high water concentration (often freshwater) through a semipermeable membrane to a region of low water concentration (often NaCl). Osmotic powers excellent environmental performance and CO2-free power production will qualify for green certificates and other supportive policy measures for renewable energy. The estimated energy cost is comparable and competitive with the other renewable energy sources. For both the commercial power companies and technology suppliers Osmotic Power represents an attractive new business potential.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Mahesh R. Nalamwa | Dr. Dhananjay K.Parbat, Dr.D.P.Singh

Abstract

With advance research in material technology, construction sector is using advance material at different stage of construction. AAC was used as construction material, which reduce the self weight of structure. AAC block are light weight and have less thermal conductivity as compared to traditional bricks. Due to use of advance energy efficient material for walls, energy consumption of building throughout the life span can be reduced. Paper deals with use of alternative material for construction of walls in building. Case study of flat scheme in seismic zone III, was presented to compare the base shear due to earthquake load, RCC estimate and reduction of carbon emission in atmosphere. Comparative was made between building constructed with tradition red brick wall and AAC brick wall. With use of advance building material saving in concrete quantity was observed. Carbon emission in atmosphere is reduced, hence structural designer can use the advance techniques to reduce the consumption of concrete and steel.

Grey Cast Iron Turning Process Modeling and Simulation using AdvantEdge 2D Edge rounding comparison for uncoated carbide inserts

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 29th July 2017

Dinesha Kumar U | Ramesh S Rao

Abstract

In the last decades, the modeling and simulation of machining processes became very important for researchers. AdvantEdge FEM is an explicit commercial code for designing, improving and optimizing machining processes. The solver is optimized for metal cutting processes. For grey cast iron turning coated carbide inserts without chip-breaker (like CNMA geometry) is being used. Insert micro-geometries like edge rounding radius r and edge symmetry S plays an important role in deciding insert wear criteria and tool life. An optimum edge rounding radius should be provided for the insert during edge honing process to obtain maximum insert tool life. The stresses acting on the tool and the temperature distributions inside the tool tip are crucial. The strength of the cemented carbide depends strongly on temperature, a dependency that increases with increasing temperature. In this paper finite element simulations of orthogonal turning of GG25 Cast Iron with uncoated cemented carbide inserts are performed. Cutting forces, stress and edge temperature distributions are compared in 2D orthogonal turning for different edge rounding radius (r = 10μm, 30μm, 50μm and 70μm) and using the actual testing parameters. The modeling and simulation of the turning process can be used to get more inputs the turning process and process parameters

Ground Effect on Aerofoil Performance

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 29th July 2017

M Sohan | Omkaresh B.R, Dr V. Ramesh

Abstract

The CFD simulation over a NACA 0012 aerofoil was carried out at subsonic speed of M=0.3 and Re=3×106 by varying AOA from 0⁰ to 16⁰ with a ground clearance of 2c under normal atmospheric conditions. Fine structured grid was created using GAMBIT and the analysis was carried out in ANSYS 16.0. Standard K-epsilon model was used to determine the flow characteristics. Lift and Drag forces were measured, pressure distribution on aerofoil was obtained and velocity survey over the surface was carried out. These values of lift coefficient was compared with the standard values ( i.e. when aerofoil is away from ground ). It was observed that lift coefficient was high when aerofoil is closer to ground. A strong suction effect was observed on lower surface of an aerofoil for lower values of AoA. It was found that higher values of pressure coefficient are obtained on lower surface when aerofoil is closer to ground. This region of high pressure almost extends over the entire lower surface for higher AoA. the drag was higher close to the ground mainly due to the modification of the lower surface pressure distribution. It was also observed that reverse flow was started to occur at higher AoA.

Groundwater Flow Modelling Using Visual MODFLOW - A Case Study of Lower Ponnaiyar Sub-Watershed, Tamilnadu, India

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 24th March 2018

Dr.N.Sridhar | Dr. K. Ezhisaivallabi, Dr.S.Poongothai, Dr. M. Palanisamy

Abstract

The groundwater model is used to predict the effects of hydrological changes like groundwater extraction or irrigation developments on the behaviour of the aquifer and is often named as groundwater simulation model. Visual MODFLOW is the U.S. Geological Survey modular finite-difference flow model, which is a computer code that solves the groundwater flow equation. In this study, the Visual MODFLOW is used to simulate the flow of groundwater through aquifers in Lower Ponnaiyar watershed, Tamilnadu, India. The three-layer model is run with four phases that are model design, calibration, validation and prediction. The model is calibrated in two stages, which is involved a steady state calibration and transient state calibration using observed groundwater levels from 2005 - 2014. The validation is done by using observed groundwater levels from 2014 - 2016. The spatial distribution of hydraulic conductivity and storage properties are optimized using a combination of trial and error method. The simulation results showed that the fluctuations of hydraulic heads are dependent on seasonal variation in recharge from natural infiltration of precipitation and irrigation. The different scenarios are developed to predict aquifer system response under different conditions of the study area. The calibrated parameters are very useful to identify the aquifer properties and to analyze the groundwater flow dynamics and the changes of groundwater levels in the study area. The study suggests that from the prediction the recharge rate must be improved in the villages like Tiruppanambakkam, Karaimedu, Agaram, Kavanippakam, Anangur, Pillur, Tiruppachanur, Pedagam and Perangiyur which are located nearer to the river course. Also, this study concluded that the water level is high in central western part and declining towards the south Ponnaiyar River.

Guidance Control and Tracking of a Missile

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd August 2017

Karthik Sivaram | Mr. Shashikanth Patil, Dr. T.C.Manjunath,Mrs. Pavithra G

Abstract

The scope of Guidance and Tracking and Classification encompasses many disciplines, including infrared, far infrared, millimeter wave, microwave, radar, and synthetic aperture radar sensors as well as the very dynamic topics of signal processing, computer vision, and pattern recognition. It is a fertile area for growth in both analysis and experimentation in military applications. The availability of ever improving computer resources and continuing improvement in sensor performance has given great impetus to this field of research. This technology "push" has been balanced by a technology "pull" resulting from increasing demand from potential users of this technology including both military and civilian entities as well as needs arising from the growing field of Homeland Security. The original tentative of guidance control has been focused mostly on the development of target detection, tracking, and classification associated with visible range sensors in day and in other hostile environments. In the last decade, infrared, thermal and other non-visible imaging sensors were used in special areas like military. That lower interest level in heat sensors was due in part to the high cost of non-visible range sensors, low image resolution, high image noise, lack of widely available data sets, and lack of consideration of the potential advantages of non-visible lights. These historical objections are becoming less relevant as infrared imaging technology advances and their cost is dropping dramatically. Image sensing devices with high dynamic range and high IR sensitivity have started to appear in a growing number of applications ranging from military and automotive domains to home and office security applications. In order to develop robust guidance and tracking system and accurate systems that operate in and beyond the radar frequency range, not only existing methods and algorithms originally developed for the existing range should be improved and adapted, but also entirely new systems that consider the potential advantages of frequency ranges are certainly required. The fusion of visible and non-visible ranges, like radar and IR images, or thermal and visible spectrum images, is another dimension to explore for a higher performance of vision-and-signal based systems. The tracking system is widely employed in visionbased systems, and many detection and recognition systems available today are relying on physiological phenomena produced by IR and thermal wavelengths.. It has to be noted that this paper is the result of the seminar report of the UG BE curriculum of the 8th semester that was undertaken by Mr. Naveen under the guidance of the faculty & the HOD.

Gurney Flap Studies on Lift and Drag of an Aero foil Naca0012

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 4th September 2017

Manjunatha Patil | Mr.Jatadhara, Dr,V.Ramesh

Abstract

In this performance we have executed the computational analysis on aerofoil to determine the effect of gurney flap on lift and drag performance of naca0012. A Gurney flap is a flat plate of order from 1 to 2% of the aerofoil chord length, aligned vertically to the chord length and positioned on the aerofoil pressure side at the rear end. This work involves a steady state, in-compressible Navier-Stokes equation solver and two dimensional CFD calculations for subsonic flow over a naca0012 aerofoil at different angle of attack and maintained at high Reynolds number at 3x are conferred using the unique equation spallart-allamaras turbulence model. Adopting a 3.0% chord length Gurney flap enhances the coefficient of lift gurney flap height preferred. The computed solutions display the detail picture of the flow system at trailing edge and give a feasible evidence for the enhanced aerodynamic function. The computational results describe the details of the flow nature at the trailing edge and provide feasible information for the increased aerodynamic performanc

Heat Death of the Universe

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 21st December 2017

Vinod Kumar Biradar | Sudarshan.D, Sanjay.M.K, SaiBaba, SandeepInamati

Abstract

Heat Death is a state of a Thermodynamic system having reached maximum entropy; Temperature is uniform throughout, and no energy is available to do work. So this theory is applied for the Universe where the Second Law of Thermodynamics states that Entropy that increases in an isolated system (in our case it’s the Universe) Entropy, which is the number of ways in which a system can be arranged should never decrease, evolving to a state of maximum disorder (or thermodynamic equilibrium). When this happens, all energy will be evenly distributed throughout the cosmos, leaving no room for any reusable energy or heat to burst into existence. Processes that consume energy, which includes our very living on Earth, would cease or End.

High-Performance Concrete: Need of Hour

S. K. Verma | R.Lal, C.S.Singla

Abstract

This paper highlights various factors responsible for the deterioration of conventional concrete, resulting in its malfunctioning during its service life. In order overcome these issues the development of High-Performance Concrete (HPC) has taken place. The primary cause for deterioration of concrete structures is found to be permeation. HPC development is aimed at minimizing this aspect with proper proportioning of available materials, apart from increasing its resistance towards sulphate attack, corrosion of embedded steel, abrasion, erosion and cavitation etc. The Desirable properties of ingredients like cement, aggregate, admixtures, water, etc. used for developing HPC1 have also been discussed. Approaches for reduction of capillary pore size and role of chemically active binding agents to improve the resistance to permeation have also been presented. Besides these, the role of quality control in placing, compaction and curing of concrete for its improved performance is also discussed.

Abstract

Biocomposites (natural fiber composites) from local and renewable resources offer significant sustainability; industrial ecology, eco-efficiency, and green chemistry are guiding the development of the next generation of materials, products, and processes. Considerable growth has been seen in the use of biocomposites in the domestic sector, building materials, aerospace industry, circuit boards, and automotive applications over the past decade, but application in other sectors until now has been limited. Nevertheless, with suitable development, the potential exists for biocomposites to enter new markets and thus stimulate an increase in demand even in the field of Fiber Metal Laminates . Many types of natural fibers have been investigated with polymer matrices to produce composite materials that are competitive with synthetic fiber composites which require special attention. Fibre Metal Laminate (FML) is largely used in the manufacture of aircrafts. The commercially available FMLs, GLARE, CARALL (CArbon Reinforced ALuminium Laminate) and ARALL make use of Aluminium metal. Other FMLs that are under study by researchers make use of metals such as Titanium and Magnesium based alloys. Owing to the high cost of carbon Fibre and the necessity for environment friendly alternatives, in the present work, a portion of carbon is replaced by natural fibre materials in CARALL and CARMAL (CArbon Reinforced MAgnesium Laminate). To the knowledge an attempt has not been made before in the field of FMLs the use of Natural fiber in place of Glass fiber and Carbon fiber In recent an attempt has been made by using a natural fibers as a laminating material by which a number of Natural materials like Fiber or flakes can be used. An attempt is also reported with jute as CArbon- Jute Reinforced ALuminium Laminate and CArbon-Jute Reinforced MAgnesium Laminate are named as CAJRALL and CAJRMAL.

Abstract

In today’s world energy crisis and depletion of resources has become major concern. So, there is need for a technology that recovers energy which usually gets wasted. In the case of automobiles one of these useful technologies is the regenerative braking system. Generally in automobiles whenever the brakes are applied the vehicle comes to a halt and the kinetic energy gets wasted due to friction in the form of heat energy. Using regenerative braking system in automobiles enables us to recover kinetic energy of the vehicle to some extent that is lost during braking process. The present work utilizes flywheel to store the energy which was actually being wasted during braking process. The kinetic energy of a vehicle which is lost during deceleration is used to accelerate a flywheel, this flywheel is subsequently coupled to transmission to assist in starting the vehicle from rest thus conserving the energy. The shape of the flywheel is important and must be designed such that stress in the material is the same throughout. Since regenerative braking results in an increase in energy output for a given energy input to a vehicle thus efficiency is improved. Therefore amount of work done by the person in pedalling the bicycle is reduced

Impact of shot peening process on the Fatigue life of a Dissimilar Metal Welded Joint

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 11th November 2017

Harish.A | 

Abstract

A dissimilar welded joint finds its prominence in high temperature applications and has better corrosion resistance. Whereas the welding process induces residual tensile stresses that are detrimental to fatigue life. Tensile stresses act to stretch or pull apart the surface of the material. With enough load cycles at a high enough tensile stress, a crack is initiated. Significant improvement in fatigue life can be obtained by modifying the residual stress level in the material. The intent of this project is to measure fatigue life and surface hardness of butt welded joint with dissimilar materials. The surface modification method employed is shot peening method which is simple, yet effective to improve the fatigue life of the joint. In this study an investigation is carried out into the effect of shot peening upon improvement in the fatigue strength and hardness of the welded joint.

Abstract

The development of electrical direct drives has reduced the need for mechanical drive components for several machines. A Direct Drive Technology is one that takes the power coming from a motor without any reduction, i.e. no transmission components are used. In our case study, we have approached a theory on removing the transmission parts of automobiles such as shafts, chains, belts. And to use the direct drive motor to the wheel. A design is in progress to fit the field coils into chassis and the permanent magnets are placed on the wheels rim. The field coil is connected to a battery and becomes temporarily magnetized once the circuit is closed. The motion is achieved due to the attraction between the field coil and the magnetic strip. A magnetic flux shield is being put to use to avoid unnecessary attraction of ferrous materials presents on the road. This new technology significantly improves the overall efficiency of Automobiles.

Abstract

As construction projects get bigger and more complex, clients are increasingly demanding higher levels of quality, efficiency, and delivery. Total Quality Management (TQM) has long been recognized as a successful management philosophy in the manufacturing and service industries. TQM can also be embraced in the construction industry to induce quality and productivity. This paper attempts to introduce the basic elements of ISO 9001:2015 and describes how each can be implemented in a wide array of construction-related companies, in order to achieve their goal of total quality. Numerous case studies were found which demonstrate the ability of ISO 9001:2015 to improve a company's quality performance, avoid costly errors, and produce satisfied customers. The benefits experienced include reduction in costs, better employee job satisfaction because they do not need to attend to defects and client complaints, recognition by clients, work carried out correctly right from the start, subcontractors with proper quality management systems, and closer relationships with subcontractors and suppliers. TQM performance measures were also reflected through top management commitment, customer involvement and satisfaction, employee involvement and empowerment, customer supplier relationships, and process improvement and management

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 2nd March 2018

Akash W. Firke | Swapnil R. Satone, Rishikesh Khope, Valsson Varghese

Abstract

Road pavements are relentlessly exposed to high traffic loads and high temperatures which imparts negative effects on the durability of the concrete. To restore the weakened concrete properties and further to enhance the performance of the pavement an effective multifunctional material is obligatory. Admixtures are widely used for this purpose. Using fly ash in concrete may both provide economic advantages and better properties in the production of concrete. Use of polypropylene fiber in concrete has been researched in recent days. Besides in addition of fiber provide better performance for the concrete while fly ash in the mixture may adjust the workability and strength losses caused by fibers and improve strength gain, durability, density, corrosion resistance, etc. Combination of fly ash and fibers has given better performance when tested. Fly ash increases 50– 60% of compressive strength and 80 – 90% of tensile strength and fiber decreases shrinkage up to 30-40%.

Abstract

As the luxury factor in transportation increases day by day, the number of vehicles on road increases and so is their emission. Ever depleting petroleum resources push researchers towards the search of new fuels and improved methods of combustion. Biodiesel obtained from vegetable oils and animal fats has comparatively low profile pollutant emissions and can be easily substituted for mineral diesel. Viscosity and density of fuel greatly influences the atomization and vaporization patterns of fuel sprays. At higher temperatures, the viscosity of fuel decreases which enhances the atomization. Better atomization improves the combustion quality of the fuel and hence reduces the HC and CO emission. In this work three blends of pungamia oil with diesel is heated to 60, 70 and 80o C. The preheated fuel is used in direct injection C I engine and the performance curves were obtained. Emission analysis was also done and the emission curves were also presented. The results show that B 20 blend gives good combustion and emission characteristics when heated to 70o C before inlet. The analysis of graph shows that B20 gives better thermal efficiency and low emission characteristics compared to diesel. The NOx emissions were drastically reduced.

Abhijeet A. Galatage | Sastish B. Patil

Abstract

Due to improper knowledge of seismic hazards buildings designed using modern principles observe earlier failure. This leads to loss of property as well as lives. Structures subjected to the earthquake are supposed to be analysed by possible practical methods for forecasting seismic demands. Hence such methods which are based on the behaviour of structures need to be developed prior to design. The exact analysis can be obtained by imparting site-specific data to predict the performance of the structure along with nonlinear analysis. Ground motions are scaled to get SSD using SEISMOMATCH 2016 to perform incremental dynamic analysis of structures using SAP 2000 subjected to several ground motions. Pushover curves are plotted for each structural model. The study is carried out considering the earthquake-prone region of north India on 5, 12 and 18-storey moment resisting RC frames. The structures analysed for selected ground motion found to be more efficient for absorbing like actual vibrations and also make the analysis procedure more effective

Abstract

Corrosion of reinforcement is one of the leading causes of the deterioration in reinforced concrete structures. Reinforced concrete is recognized to be durable and capable of withstanding a variety of environment conditions. Nevertheless, premature failures of structures still do occur as a result of steel reinforcement corrosion. RC structures damaged by reinforcement corrosion can exhibit not only reduction of the bearing capacity but also an alteration of the collapse mechanism with a reduction in the structural ductility. All of these actions contribute to the loss of stiffness and ductility of the RC Structure and thus, reduce the ultimate strength of the structure. This review paper focuses on the various studies of effect of accelerated corrosion on steel bar and its influence on strength and durability of RC structure. Thereby a comprehensive review of studies on strength of corroded RC columns & beams, concrete cover depth effect on crack width and its effect on corrosion, is presented.

Akash Dahalkar | M. D. Goel

Abstract

Earthquake is a natural and unpredictable calamity. It leads to loss of precious human life and property and at the same time pushes the national economy in the backward direction. As we know occurrence and magnitude of an earthquake are unpredictable. So, codes need regular updating to provide safety to the structures and human lives as well. These codal provisions are based on the return period of the earthquake and its magnitude. By employing these magnitudes into considerations, codal provisions have been revised regularly and has a different significance based on the earthquake zones. The prime objective of this investigation is to study the influence of seismic parameters if a building existing in zones with less seismic probability, experienced severe earthquake shakings and what should be the safety measures we need to provide for the safety of the structure and human life as well in such cases? To understand this, a G+6 storied reinforced concrete building is modelled using commercially available 3-Dimensional Structural Analysis and Design Software (STAAD.Pro) and then analysed for the different zones against earthquake forces. Seismic analysis has been done with dynamic linear analysis by using response spectrum analysis method by taking the significance of all the zones in India. Use of master-slave has shown the reduction in nodal displacements. Based on this study, it is concluded that analysis with master-slave results in economical design in comparison with design without considering master-slave.

Mohammed Idrees | Mohammad Irshad Ali, Lokhesh Kumar Nagisetty

Abstract

Aluminium and Aluminium alloys are rapidly growing materials and has found many new applications in engineering materials. Applications of Aluminium and Aluminium alloys are increasing because of light weight, high strength to weight ratio, high corrosion resistance, low cost etc. Joining is a key technology in all the major applications of Aluminium which can be usually achieved by various welding techniques. GTAW( Gas Tungsten Arc Welding ) is one of the most promising methods for welding of Aluminum. However Aluminium suffers changes in hardness and tensile strength, when different welding parameters are varied. For instance if one parameter is kept constant and the remaining varied then a drastic change in hardness, tensile strength and microstructure may be seen. This study basically deals with influence of two basic parameters ( welding current and shielding gas flow rate ) on GTAW welded butt joints of AA6351.After welding was performed Vickers hardness test and Tensile test was conducted to know the influence of process parameters on hardness and ultimate tensile strength respectively. and later Microstructure test was also conducted to know the microstructural changes in the base metal after welding has been performed. Each of the test result was then analyzed to come to a conclusion

Abstract

Infrared thermography is a modern non-destructive measuring method for the examination of redeveloped and non-renovated buildings. Infrared cameras provide a means for temperature measurement in building constructions from inside and outside as well. It has been shown that infrared thermography is applicable for insulation inspection, identifying air leakage and heat losses sources, finding the exact position of heating tubes or for discovering the reasons why mould, moisture is growing in an area and it is also used in conservation field to detect hidden characteristics or degradations of building structures. Infrared thermography is equipment or method, which detects infrared energy emitted from an object, converts it to temperature, and displays image of temperature distribution. In Construction Industries, the application of infrared thermography is not limited to passive investigations but active investigation too. Some defects like voids in concrete or masonry, delaminations at interfaces of an object which have a different density or heat conductivity can also be detected and characterized. Infrared thermography, due to its non-contact character that allows for quick 2D surface mapping, represents a powerful tool for non-destructive testing (NDT) of materials and structures. As Infrared thermography is still not completely exploited and traditional methods are still employed. Due to the ambiguity in the analysis by using traditional methods of non-destructive testing this method emerge as an easy and quick method. So, in this paper, different areas are taken for inspection on the campus of Veermata Jijabai Technological Institute, Matunga, Mumbai, and at the same location traditional methods of NDT are also performed and the results are compared. Thus, temperature measurement must be completed during a short-elapsed time after the pulse heating. The infrared thermography is useful in detecting invisible defects non-destructively, extensively and safely.

Intelligent Control of Sensor Based Robotic System

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Rajesh Babu | 

Abstract

With the advent of computers in the field of programmable automation, control of production process has assumed new dimensions. As a matter of fact, robot is indispensible in such production systems. Effective control of such systems requires special sensory devices to interact with the environment in a more meaningful and flexible manner. To achieve this objective, factory of future should imbibe human intelligence at all levels of manufacturing, particularly robot motion/force control. This will result in improved product quality and hence customer satisfaction. Online feedback of sensory information is the basis for the development of more intelligent robot that comes closer to the performance of human arms. This information when coupled with new control strategies will definitely guide the robot to perform its intended function with highest accuracy and precision. But in such complex systems as in robotic system, it is often difficult to coordinate sensory information with the control task. This is due to the undesirable feedback delays or fundamental sensor limitations. Against this backdrop, the present work focuses on toying with the idea of exploring new control strategies namely “Intelligent Control Approaches” that refer both to the control design approach or philosophy and to implementation techniques that emulate certain characteristics of intelligent biological systems

Abstract

Today, organizations worldwide from manufacturers, to hospitals, to banks, to software developers, to governments are making a difference by adopting kaizen philosophies, mind-sets, and methodologies. Even though the names of these strategies may change over the decades from continuous quality improvement and total quality management, to just-in-time and operational excellence, to six sigma and lean manufacturing, the most successful of these strategies are customer-focused, gemba-oriented, and kaizen-driven. Kaizen is one of the principles that support the Toyota Production System (TPS) as a philosophy. Thus, it is tried to use it in the field of Construction Industry (CI) because of its inherent characteristics of production. And hence a model was developed to aid the professional of the CI to systematically advance a kaizen project with the use of diagnostic tools and analysis of the production system. The research method is defined by three sequential steps governed by two research strategies: theoretical-conceptual - for the literature review and development of the model, and action-research - aiming the implementation of the model in a building site for housing production. As a result of the action-research strategy, using the model, nine problems as well as their roots and kaizen opportunities were identified and classified in the productive system. The systematization of the generation of kaizen opportunities for the CI contributes directly to the quality of the final products and to the reduction of costs of building sites, because it allows for continuous improvements of processes based on higher levels of value added with the reduction of the use of resources in the production system.

Three specimens are tested at a time for constant conditions as per ASTM standards, the matrix material without the reinforcements was also subjected to the wear tests to achieve a comparing with the composite material with different percentages of nanoclay. From the results it is observed that, Corrosive erosive wear rate varies marginally at lower speeds but increase sharply at higher speed. The corrosive wear rate logarithmically increased with the increasing concentration of the corrosive medium. The composites attained better corrosive-erosive (Vce) wear resistance than the matrix alloy irrespective of the test condition The erosive-corrosive wear rate of the specimen have an exponential relation with the HCL concentration and erosion speed of the slurry, Corrosive wear was the predominant mechanism of material removal in the corrosion and abrasion modes of wear. The effect of abrasive particles and corrosion medium on the wear behaviour of the composite is explained experimentally and compared with ascast aluminium alloy

Abstract

This research work deals with the experimental investigation of the composite material of aluminium with fly ash. Aluminium material grade 6063 is chosen for this investigation of metal matrix composites. There has been an increasing interest in composites containing low density and low-cost reinforcements. Fly ash is low-cost material available in large quantities which are obtained from the combustion of coal in power plants. Hence, composites with fly ash as reinforcement are likely to overcome the cost barrier for widespread applications in automotive and small engine applications. By using stir casting method, the composite can be obtained with aluminium. We used the composite material to make a much effective prototype or mechanical structure having very good mechanical properties. Properties of composite materials completely depend on the method used to produce it. Aluminium with Fly ash materials were fabricated using Stir casting method. After composite matrix, the materials are observed and investigated. Dry sliding wear behaviour of the composites in the cast conditions is studied at different loads with the help of Pin-On-Disc wear test machine. Finally, mechanical properties such as hardness and tensile strength have been investigated.

Pavankumar | R Sonawane, Dr. M. Chandrasekaran

Abstract

Drag force had significant contribution in the fuel consumption. The main objective of this paper is to determine the aerodynamic drag force for Car body by using computational fluid dynamics simulation software. In this paper the model of Car is created with the help of Computer Aided Design software. The magnitude of drag forces are determined by simulation run for rear slant angle of Car body. Afterward rear slant angle is varied by the span of 10 degrees. This time simulation run is carried out on these CAD car models to predict the drag forces for different velocities like 11.11 m/s, 16.66 m/s and 22.22 m/s. Wind tunnel experimentation is cost associated and time consuming work. This analysis shows that change in rear slant angle of the Car body from 55 to 45 degrees corresponds to reduction in drag force up to 16 %. The reduction in drag will lead to saving in fuel consumption.

Abstract

Pin-fin heat sinks show their great merits of thermal management in high heat flux devices in micro-electronics, energy and aerospace and in heat exchange equipment. Compact heat transfer mechanism is needed to remove the heat flux and increasing heat transfer rate. In this study, three cylindrical pin-fins with different materials i.e. mild steel, brass and aluminium are of same sizes studied experimentally with forced heat transfer technique. How the efficiency and heat transfer rate are affected by the changing in Reynolds number. Heat transfer coefficient changes by changing the material and flow properties, result in an increasing heat transfer rate over the plane channel. This study is to experimentally examine the effect of cylindrical pin-fins of brass, aluminium and mild steel on the heat transfer rate at various Reynolds number with considerable practical importance.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Prakhar Negi | R.K. Ingle

Abstract

This paper conducts the study to investigate the in-plane and out-of-plane buckling of tied-arch bridge. Several analytical models of tied arch with varying span to height ratio and hanger numbers are studied. It has been shown from results that the recommended values of European standards (Eurocode 3: 1993-2) for predicting the in-plane and out-of-plane buckling length factor of tied arch bridges is not rational and often leads to unsafe design. The in-plane buckling length factor not only depends on the stiffness of main arch girders but also depends on the stiffness of deck and vertical ties. Furthermore, it is difficult to predict the first mode of buckling, It largely depends on the effectiveness of a bracing system. To predict the actual critical buckling force it is of paramount importance to know the first buckling mode. In last it is concluded that tied arches are complex structures owing to its various parameters which are difficult to formulate in terms of codal procedures, Therefore more emphasis should be given in actual modeling

Abstract

Additive Manufacturing is a professional production technique which builds up complex shaped parts layer by layer, as opposed to subtractive manufacturing methodologies by using the .stl file as input. The mechanical strength of polymer-based additive manufacturing components is not sufficient to meet the demands of functional end tooling operations. Surface roughness also should be improved for its effective implementation in various applications. Many research methodologies were proposed to improve the mechanical strength and surface properties of additive manufacturing components but post-processing characterization is a kind of method which is highly concentrated in recent years by various organizations. A pilot study was conducted among the available techniques like D.C sputtering, electroforming and electroplating by using specimens which were fabricated in different orientations and it was found that the electroplating process provided good adherence of coating material over substrate when comparing to other two processes. In this study fused deposition modelling technique was used to fabricate acrylonitrile butadiene styrene parts in 0,30,45,60 and 90-degree orientations and these parts were electroplated with copper by using sulphuric acid as electrolyte. The tensile and flexural tests were carried out over electroplated and non-electroplated specimens to analyze the effect of different orientations on the anisotropic behaviour of parts. Surface roughness test was also carried out over electroplated and non-electroplated specimens by using portable surface roughness tester to analyze the effect of different orientation over surface roughness properties. The results indicated that there is a significant amount of improvement in surface roughness properties and mechanical properties of electroplated specimens when comparing to non-electroplated specimens that show a possibility for utilizing this methodology in end tooling applications.

M. Maruthi Rao | Dr. N.V.V.S. Sudheer

Abstract

In this work the suitability of biological quenching medium for age hardening of aluminum alloy has been investigated. An attempt was made to add different percentages of cow and sheep urine in base quenching media(water) separately to study its effect on the micro structural and mechanical properties of cast aluminum alloy. Cow and sheep urine are supposed to contain rich quantities of sodium, nitrogen, sulphur, manganese, silicon etc., homogeneously present. Test samples of aluminum alloy were age hardened at 450 C, 400 C, 350 C by soaking for one hour and then investigated for different strength parameters. The results showed significant increase in ultimate tensile strength, yield strength and hardness possibly due to above elements present in the cow and sheep urine. Sodium present in the cow and sheep urine could be the reason for grain refinement and silicon along other elements could have helped in interlocking of grain boundaries. The values are in coincidence with recommended values of age hardening of aluminum alloy in base quenching media.

Abstract

A remarkable growth is observed in the automobile as well as industrial sectors and accordingly the requirement for the fossil fuels is also increasing. As a result, the amount of fossil fuels available is decreasing drastically. It is well know that modern world depends mostly on energy produced from different energy sources, because of their various uses. Most of the energy sources are fossil fuels which are getting exhausted. Therefore, many scientists from different parts of the globe are carrying out research to find an alternative source in order to replace the existing one. Biodiesel can replace the present energy crisis and further help in reducing global warming. It is mainly produced from edible and non-edible oils. Non-edible oils when blended with diesel give rise to biofuels which have exhibited a remarkable growth in the automobile industries because of their environment friendly and lubricating nature. The present paper elaborates about the emission characteristics of an agricultural diesel engine utilizing jatropha oil methyl ester with diesel blends (B10, B20 and B30). All the emission values were noted and plotted in the graph against loads varying at 0%, 20%, 40%, 60%, 80%, 100%. The results depict that BD20 is the blend which shows the less tendency towards emissions like CO, CO2, HC, while there is a slight increment in both NOx and smoke emission in comparison to other test fuel blends which gives a conclusion that B20 is a best alternative fuel capable of replacing current petroleum diesel fuels to reduce the engine emissions..

Abstract

Miniaturization of the products/processes is no more a fashion rather it is the need of the time because one can drive multifarious benefits from such products/processes, namely they are very simple, occupy less space, low power consumption, more flexible, saving in material and many more. Hence fabrication of these miniaturized products presents challenges in many areas of engineering. Micromachining is the foundation of the technology to realize such miniaturized products. Micro-Electro Discharge Machining (μ-EDM) is one such high precision non-conventional machining process in which electrical discharges are produced between the tool electrode and the work piece electrode immersed in dielectric fluid. The electrical discharges thus produced remove the work piece material through melting and evaporation process and results in the creation of micro features on any conducting and semiconducting engineering materials irrespective of their size, shape and mechanical properties like strength, hardness, refractoriness etc. Some of the engineering materials machined using EDM are tungsten, tungsten carbide, copper, copper tungsten alloy, silver, brass, graphite, beryllium copper alloy, hardenable steels etc. Now the process is extends to machine semiconducting material like silicon wafer. In this paper, some of the results obtained while performing the investigation on machining of blind holes on silica wafer using developed μ-EDM process. Blind holes are produced on silicon wafer of 100 μm thicknesses with copper wire of 610 μm diameter as a tool electrode and stainless steel of 710 μm diameter as a tool electrode using Kerosene and Deionized water as dielectric fluids. The repeatability of the depth and surface finish of the blind holes are verified with constant time period by varying frequencies.

Abstract

Productivity of cutting tool inserts in machining high strength and high temperature resistance alloys is an issue of concern. This drawback persists in case of Sintered carbides also, that have machining capabilities comparable with HSS and Cast Steel alloys. Many innovative methods have been implemented in this regard, out of which cryogenic treatment appears to be a promising technique. In this technique tool inserts are soaked in a controlled atmosphere at beyond -150 0C for predetermined time and brought back to room temperature. This treatment normally leads to contraction of metal structure increasing hardness and related properties. In the present work untreated Tungsten carbide tool inserts have been subjected to Cryogenic treatment at -193 0C followed by tempering cycle to relieve stresses formed during cooling. The treated samples showed improved hardness and tool life when subjected to machining tests at different cutting velocities. The microstructure study showed the formation of complex carbide phases and further studies revealed the increased population of carbides and cobalt binder which have contributed towards improvement in properties.

Abstract

Energy is the main input in the technological, socio-economical, and industrial development of any country. Petroleum-derived Fuels are the major source of energy throughout the world. However, these fuels are not only limited but also pollute the environment. In India, the diesel fuel is extensively used in transportation, agriculture, and industrial sector and the consumption of diesel is four to five times that of gasoline. However, diesel engines are the main contributor to environmental degradation. Due to growing awareness about climate change and depletion of fossil origin fuels, exhaustive research is carried all around the globe to evaluate the suitability of the variety of alternative fuels. Biodiesel, which is carried all around the globe to evaluate the suitability of the variety of alternative fuels. Biodiesel, which is produced from the variety of vegetable oils and animal fat through transesterification, has a lot of technical advantages over fossil fuels such as lower overall exhaust emission and toxicity, biodegradability, derivation from the renewable and domestic feedstock, negligible sulfur content. Biodiesel has a comparable energy density, cetane number, heat of vaporization and stoichiometric air-fuel ratio with that of the diesel fuel. Non-edible oil derived from Kusum (Schleichera Oleosa), an oil-bearing plant, is a potential feedstock for biodiesel production. In the present study, various physio-chemical parameters of the Kusum oil have been studied to evaluate its suitability as a potential feedstock for biodiesel production. The fatty acids are 40% whereas saturated fatty acids are around 53%. In the light of the exhaustive study, it can be that Kusum oil is a promising feedstock for biodiesel production for use as a fuel to improve its commercial viability.

Joel Mascarenhas | V.A. Girish L.J.Kirthan,B. R. Rao

Abstract

Thermal fatigue stress cracking is one of the major modes of failure in high pressure die casting dies. The aim of this work was to predict the life of the die using fracture mechanics concept and optimize the design to improve its life. In this work, first the crack length was measured at the critical location. Then a transient thermal analysis and thermo- mechanical coupled analysis was performed in ANSYS Workbench on the actual die to obtain maximum stress occurring in the die. The stress value and the crack length measured were substituted in Paris law to obtain theoretical life. The theoretical life was compared with the actual life and an error of less than 5% was obtained. With the successful life estimation, two new designs using an optimized cooling circuit was proposed and same was analyzed using ANSYS. The die providing less thermal stress was chosen as an optimized design.

Abstract

The paper finds that tilting trikes inherit leaning and dynamic stability characteristics from bicycles and the potential for static stability from trikes. Tilting removes the need for a trike to be wide and low to stay stable during cornering. This can make the trikes more visible and acceptable from a car driver’s perspective compared to a standard, low recumbent trike. High-end tilting trikes can have hybrid (human / electric) drives and meet the need for comfortable, sheltered vehicles capable of taking luggage on long commutes. These expensive high end tilters are not widely available in Australia. Less complex tilters can be better-than

Literature Review – Behaviour of Cold Formed Z Purlins with Sag Rods in PEBs

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 26th February 2018

Kanchan S Takale | Dr. Ramesh V Meghrajani

Abstract

Cold formed steel is widely used in Pre-engineered buildings. It has gained popularity for its unique features of lightweight, better and standard connections, faster execution, etc. However, larger variations in the moment of inertias with respect to X and Y axis have led to distortional buckling in the members. Cold formed purlins have depths 100 times to that of its thicknesses. This has promoted lateral torsional buckling in the member for the unbraced length of the purlins. Use of sag rods is a widely adopted technique to curb the lateral torsional buckling in the member. This paper discusses a detailed review of the literature on deformations in cold formed Zed profiles, their comparisons and conclusions. The data generated through the literature survey will help to generate better and well-defined configurations of Z purlins and stable models for analysis.

Literature Review on Steel Fibre Reinforced GEOPOLYMER Concrete

Abstract

The Geo-polymer concrete (GPC) is representing the most promising green and eco-friendly substitute to Ordinary Portland cement (OPC). One of the most important ingredients in the conventional concrete is the Portland cement. The production of cement in the factory emits the enormous amount of carbon- dioxide which pollutes the environment. Therefore, low calcium fly ash based geopolymer concrete is provided because this concrete uses no Portland cement. The geo-polymer cement (which is obtained from the reaction of low calcium fly ash with the alkaline solution (i.e.) sodium hydroxide and sodium silicate) does not pollute the environment and so it is eco-friendly. SFRMGPC consisting of fly ash, GGBS, Alkali-activated solution, fine aggregate, coarse aggregate and steel fiber. GGBS is obtained as a by-product i.e. waste from iron and steel industry from the blast furnace to produce a glassy, granular product which is then dried and crushed into a fine powder. It Increases the long-term strength, durability, and resistance to attack in peaty/acidic environments. To enhance the curing ground granulated blast furnace slag is added. Steel fibers increase the durability of geo-polymer concrete and it is proposed to determine and compare the differences in properties of geo-polymer concrete with GGBS and steel fiber. The investigation will consist 0f several tests which include workability test, compression test, split tensile strength and flexural strength. The fiber content varied from 0 to 1 % by weight of geo-polymer binder (Fly ash + GGBFS), also try to use of best molarity alkali solution. Concrete cube of 150mm x 150mm x 150mm will be considered for compression strength. Concrete cylindrical cube of internal diameter 15omm and height of 300mm will be considered for split tensile strength. Beams of 150mm x 150mm x 700 mm will be considered for the flexural strength. In this paper, an attempt is made to study steel fiber reinforced geo-polymer concrete by various aspects.

Rahul Kishore | Sounak K Choudhury,Kashfull Orra

Abstract

Work in this paper is primarily focused on monitoring and controlling the tool vibration using magneto-rheological damper. Magneto–rheological damper consists of MR fluid whose viscosity and shearing stress can be controlled by changing the magnetic field around it with the help of current passing through the coils wrapped around the fluid container. The study involves the characterization of MR fluid as well as vibration characterization of MR damper. Thus MR damper provides variable stiffness and better damping ability and hence better control over the process. The experimental results show that dynamic response and machining parameters (tool wear, surface roughness and cutting force) of the cutting tool system is improved to a great extent when MR damper was employed. In this paper, transmissibility approach and half-power bandwidth method were incorporated to analyse the signal amplitude ratio, the damping ratio and settling time of MR damper. In addition to this dynamic stability of the cutting tool holder was obtained with the second mode of vibration using ANSYS. With the help of MR damper, the tool vibration was reduced to a great extent which ensures the reduction in tool wear, less fluctuation in cutting force, less power consumption and hence better tool life and improved productivity.

Abstract

All the Buildings and structures constructed over a period of time have a certain lifespan, depending on the materials and technology adopted therein. There are large numbers of buildings which are to be cherished as important structures in various aspects which have stood well over a period of time. The aspects may vary from being heritage, civic or simply being a distinct masterpiece of a particular era. Many of these buildings in course of time exhibit a sign of distress. The reason for this distress may vary. It may be due to its age, exposure to the hostile natural environment, pollution or sheer negligence in its maintenance or misuse and overloading of the structure etc. Repair and Rehabilitation is defined as the process of achieving the original state of structure when it undergoes any sort of defects or deterioration or destruction. Repair and Rehabilitation is an Artwork, which not only extends the life of a structure but also ensures that the structure stays intact exhibiting the character of the construction and architecture of a particular era. Restoration of structure is an ultimate aim of Repair and Rehabilitation, Restoring the structural as well as design character of the building. Architectural identity of any structure is governed by the choice of materials and techniques adopted, which have been unique to that period. Hence it becomes obvious that due consideration shall be given in selecting not only suitable but relevant materials for Repair and Restoration works of such structures. However in due course of time, in the process of this restoration the focus remains on the strength of the material unconsciously neglecting the architectural character governed by that material. This paper throws light on the facts that due consideration to be given on this aspect of material selection, in the Repairs and Rehabilitation process. It put forth an urge that selection of Materials for Repairs and Rehabilitation of Structure plays an important role in reshaping the Architectural Character of a particular era.

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 13th July 2017

Nitesh Sambhaji Pawar | Dr. Sumedh Mhaske

Abstract

Surface wave method was introduced as a tool to the geotechnical and infrastructure engineering fields in the early 1980’s. The non-invasive seismic method of multi-channel analysis of surface waves (MASW) is often used to map shear wave velocity variation of soil with depth. In an attempt to increase confidence in the interpreted shear wave velocity (Vs) profile as a result of the ambiguity in the analyzed dispersion characteristics, multichannel method is used in this research to characterize a test site on the ground of Veermata Jijabai Technological Institute (VJTI), Matunga, Mumbai. The multichannel analysis of surface waves (MASW) method originated from the traditional seismic exploration approach that employs multiple (twelve or more) receivers placed along a linear survey line. The present paper indicates results from MASW survey at a site along the VJTI college ground, for which the MASW data acquisition involved the use of a 12- channel PASI seismograph and a 12 nos. of 4.5-Hz Vertical geophones spaced at 5 m each and source offset 7m. The seismic source was a Sledge hammer (10 lbs). WinMasw 6.0 standard version software package was used to process and invert the Surface-wave seismic data in addition to generating the one-dimensional depth versus Shear Wave Velocity (Vs) profiles. The average shear wave velocity of the current study area is 228 m/s. The average shear wave velocity for Mumbai city is ranging from 110 to 350 m/s. The results determine, benefits of using non-invasive MASW method to construction engineering field in a cost effective and time effective manner as compared to conventional standard penetration test, drilling method.

Abstract

Now-a-days, the natural fibres from renewable natural resources offer the potential to act as a reinforcing material for polymer composites alternative to the use of glass, carbon and other man-made fibres. Among various fibres, jute is most widely used natural fibre due to its advantages like easy availability, low density, low production cost and satisfactory mechanical properties. For a composite material, its mechanical behaviour depends on many factors such as fibre content, orientation, types, length etc. Attempts have been made in this research work to study the effect of fibre loading and orientation on the physical and mechanical behaviour of jute/glass fibre reinforced epoxy based hybrid composites. A hybrid composite is a combination of two or more different types of fibre in which one type of fibre balance the deficiency of another fibre. Composites of various compositions with three different fibre orientation (0°, 30° and 40°) are fabricated using simple hand lay-up technique. It has been observed that there is a significant effect of fibre loading and orientation on the performance of sisal and bamboo reinforced epoxy based composites. The developed composites undergo different kinds of tests. The result shows hybrid composites having good strength and stiffness compared to natural hybrid composites

Abstract

A developed -Ti-xNb-3.5%Sn (wt%) alloy was synthesized by mechanical alloying of high energy ball milled powders and powder consolidation with cold isostatic pressure (CIP). The starting powder materials were as mixed powders and powders were produced by high energy ball milling (HEBM) for 1 hr, 2 hr, and 4 hr respectively. The bulk solid samples were fabricated by the (CIP at the temperature of 900-1050 oC for 2 hrs. It was found that the Ti was completely transformed from   phase after milling for 4 hr in the powder state, and almost transformed to -Ti phase with the sintered specimen at 1000 oC. The homogeneity of the sintered specimen increases as the milling time, Nb contents, and sintering temperature increase. Also, the hardness of the sintered alloys increases as the increase of sintering temperature, Nb contents and milling time, reached to a value of 400 HV with 4 hr milling time. The Young's modulus is almost constant for all sintered Ti-x%Nb-3.5%Sn specimens at different milling time. Young's modulus is law (62.-66Gpa) compared to the standard alloy of Ti-6Al-4V about (110 Gpa).

Abstract

The concrete industry is consuming approximately one billion tonnes of mixing water annually. In addition, large quantities of fresh water are also used for washing the aggregates and curing of concrete which is unaccounted for. The current trend all over the world is to utilize the treated and untreated industrial by-products as a raw material in concrete. This practice not only helps in reuse of the waste material but also creates a cleaner and greener environment. It is very much understandable at this point of time that a variety of supplementary materials and industrial by-products have been successfully incorporated as raw material substitutes, additives, and admixtures in cement and concrete.However, a limited research is being reported for the replacement of water used for mixing and curing.It is reported that approximately, 150 litres of water is required per cubic metre of concrete mixture, without considering other applications of water at the concrete industry. It is to be noted that water is a critical environmental issue and fresh water supplies are becoming limited worldwide. Similar to natural materials like limestone and aggregates, even potable water is becoming scarce.India is facing serious water crisis even for drinking water. The reason are increased population, urbanisation, industrialisation or be it inadequate amount of rain. Considering this above scenario into consideration, authors have presented an idea about possible utilization of treated domestic waste water in the concrete and the detail of the investigation will be presented in this paper. The effect of compressive strength of the concrete when treated domestic waste water is used as both mixing and curing waterwill be reported. Concrete cubes will be cast with both treated waste water and laboratory water and later cured with both treated domestic waste water and laboratory water. Compressive strength test would be carried out on the cubes for 3, 7, 28 and 90days and the findings are reported.

Abstract

In Electroless nickel phosphorus coatings, the corrosion and wear resistance is determined by the percentage weight of phosphorus in the coating. In order to improve the sustainability of Nickel- Phosphorus coating on a substrate subjected to wear and corrosion during use, by using varying temperature and pH levels, bilayer and duplex coating are coated on the sample and a comparative study was conducted along with the conventional mono-layer coating and the results were analyzed. Bilayer and duplex coatings constituted of two layers of 10 micrometers, each was prepared according to three distinct configurations (medium Phosphorous, High Phosphorous, and a Duplex layer). The hardness characteristics of duplex coatings are influenced by the hardness of Ni3P phase in the coatings which are found to be more stable and is obtained by heat treatment after the coating process is completed. The duplex coated sample is heat-treated to check whether there is any change in the corrosion properties while increasing the surface hardness. The wear test was conducted on a pin on disc apparatus, corrosion testing method used was salt spray corrosion testing, surface hardness / micro hardness was calculated using a micro Vicker’s hardness tester.

Abstract

The growth rate of vehicles is the backbone of economic development of any country. India is the second fast growing automobile industry in the world. In todays era, solid waste management is the thrust area. On the other side, the traffic intensity is also increasing. As a result amount of waste tyres is also increasing. Today these are generally disposed by burning and landfilling. The main objective of this study is to determine the effects of crumb rubber on bituminous mix. An attempt has been made to use Crumb Rubber; blended using wet process .Marshall method of bituminous mix design was carried out for varying percentages of Crumb Rubber to determine the different mix design characteristics. Marshalls was carried out by changing the crumb rubber content at constant optimum binder content and subsequent tests have been performed to determine the different mix design characteristics. This has resulted in much improved characteristics when compared with straight run bitumen. Crumb rubber modification has shown the ability to improve the rutting resistance, resilience modulus, and fatigue cracking resistance of asphaltic mixes. This is due to the alteration to the property of the bituminous binder in terms of the viscosity, softening point, loss modulus, and storage modulus. Use of crumb rubber also leads to excellent pavement life, driving comfort and low maintenance.

Modeling and Experimental Investigation on Micro Abrasive Jet Machining

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 31st May 2017

Anu Tomy | Kumar Abhishek, Somashekhar S Hiremath

Abstract

Abrasive Jet Machining (AJM) is one of the high precision nonconventional mechanical machining processes in which material is removed by the impingement of high velocity stream of air and abrasives on to the work surface. The mechanics of material removal is mechanical erosion. The fractures of workpiece material in the form of small debris get carried away by the air from the cutting zone. This machining is well suited for brittle and ductile materials, where in brittle materials brittle fracture and for ductile materials shear fracture takes place. Most of the researchers are focused on machining of both the materials using developed/commercial setups. Less number of literatures concentrates on modeling concepts. An attempt has been carried out to develop a semi empirical model for material removal rate (MRR) on brittle material with AJM using dimensional technique. This is carried out by incorporating the various process parameters –pressure (P), stand of distance –SOD (S) and size of the particles (rp). The developed model was then validated with the experimental results.

Abstract

Power plants are the significant wellsprings of air contamination. Coal is the essential fuel utilized for era of power as a part of India and its use is consistently expanding to meet the developing vitality requests of the nation. Emissions of greenhouse gases and other pollutants such as Suspended Particulate Matter (SPM), Sulfur Dioxide (SO2), and Nitrogen Oxides (NOx) are increasing parallel to the growing demands of electricity. This paper presents the contextual investigation for Kakathiya Thermal Power Project (KTPP) for the expectation of the SPM, NOx, and SO2, contamination brought about by warm exercises near the villages of Bhoopalaallimandal of Warangal District, Telanagana State. An atmospheric dispersion model AERMOD-9.1(American Meteorological Environmental Protection Agency Regulatory Model) was used. Meteorological data for one year was processed using AERMET processor. The model was run for modeling of dispersion of pollutants SPM, SO2 and NOxfor all the months of the study period from January 2014 to December 2014 over study area. Model also runs for yearly averaged emission scenarios. The output files for the parameters Suspended particulate matter (SPM), Sulfur dioxide (SO2), and Nitrogen oxides (NOx) were evolved. The isopleths were plotted for the same and these concentration contours are very important in determining the spatial distribution of criteria pollutants over the modeled area. For the Ambient Air Quality Monitoring Stations, the predicted concentrations were found to be in good agreement with the measured concentrations. For AERMOD model, values of coefficient of determination R2 are in the range 0.73 to 0.85. The predictions are of reasonable accuracy and may be used for any other industry in its vicinity up to 50 km Diameter.

Abstract

The machining of aluminum silicon oxide produced using rice husk is used in high speed conditions in CNC in light of the fact that such composites have extensive applications in the aeronautics industry. The motivation behind this examination is to research the impacts of cutting parameters on surface finish in high precision CNC processing machine because industry requires top-notch results, the forecast of surface roughness, which relies upon process parameters like speed, feed, and depth of cut, and step over ratio. An observational relationship is set up amongst dependent and independent factors from nine trials directed by Taguchi L9 orthogonal exhibit as linear regression conditions in MINITAB 18 software. The machining of AlSiO2 is done on rapid CNC processing machine utilizing face mill of diameter 50 mm and the outcomes are investigated

Abstract

A composite is a structural material that consists of two or more constituents combined at a macroscopic level and not soluble in each other. The advantages of composites over conventional materials are its Lightweight, High Strength, Design flexibility, Dimensional Stability etc. Although composite materials are advantageous than conventional materials, there are some defects in composite materials too, which are Fibre-matrix debonding, fiber misalignment, Delamination, Matrix cracking, Impact damage etc. Among these defects, Delamination is one of the major modes of failure for composite materials wherein separation of two adjacent plies in a composite laminate takes place. Delamination can be studied using two approaches, viz., Virtual Crack Closure Technique (VCCT), Cohesive Zone Modelling (CZM). VCCT is the study of damage based on the Energy Release rate of the material undergoing Delamination. In the present study, Finite Element Modelling and Engineering analysis of DCB and ENF standard specimens have been carried out by using the VCCT approach. Various parametric studies on the behavior of delamination with different material properties, ply orientations and a case study on different crack lengths are also studied and their effect on Delamination is presented

Abstract

composite laminates are most widely applied in the field of engineering where weight ratio and delamination are the most influencing key factors. A Finite Element (FE) based simulation technique is carried in studying the delamination of single lap joint. FE based software ANSYS (ACP) has been used for this simulation. The pre-post ANSYS ACP model was developed to check the effect of delamination region with different number of plies and to check the resistance to delamination. Three-dimensional non-linear FE analysis have been carried out to study the effect on surface interlaminar stress in the bonded lap joint. In the further study, frictional forces and pressure distribution on the laminated are analyzed using the penalty formulation. Contact FE analysis is performed in order to prevent interpretation of the laminated structures.

Abstract

Today most organizations prefer to outsource their data to the cloud. The outsourced documents and files should be encrypted because of the protection and secrecy worries of their proprietor. As a large amount of data from various clients is getting accumulated on the cloud, this raises the issue of security and privacy to its proprietors. Data being large, quick efficient and authorized search is a challenge. An efficient multi-keyword ranked search scheme is proposed in this paper that is able to address the aforementioned problems. Bloom filters are used to enhance search duration. Relevance scoring technique is used to generate ranking results in view of the top-k precision. Inside of this framework, we implemented the blind storage technique to cover access pattern of the search user. Till now the search authorization problem was not considered, that is the cloud server only has to return the search results to authorized users. In this paper, we propose an authorized and ranked multi-keyword search scheme over encrypted cloud data. Identity Based-authentication is used for authentication with AES for encryption. As a result, information leakage can be eliminated and data security is ensured. Security and performance analysis show that the proposed scheme can achieve much improved efficiency in terms of accuracy, search time and security compared with the search algorithm used in EMRS i.e Efficient Multi-keyword Rank Search scheme.
