AnjumAnwarShaik | Shamanth.T, Syed Mohsin, Zamran Lateef Baig

Abstract

The study is intended to investigate mechanical properties of LM6 based metal matrix composite, where Albite particulates are character enhancing reinforcement. Composites were fabricated by chill casting process utilizing copper as a chill. Specimens were prepared as per ASTM standards at different weight percentages of Albite varied from 0 to 12 with an increment of 3. The microstructure study clearly indicates the uniform distribution of Albite particulate in matrix alloy. These results revealed that increase in weight percentage of Albite as reinforcement in LM6 matrix alloy increases the tensile strength, compressive strength and hardness giving rise to the improved microstructure of composite.

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 Mathematical Model of Fluid Flows in Open Rectangular and Triangular Channels

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

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

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

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

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

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. India is moving toward a trend of generating electricity from renewable resources such as Solar, Wind, Biomass, etc. The total installed capacity for electricity generation in India is 310 GW as on 31st December 2016 in that Renewable power plant contributes 88.96 GW (28.69%) in particular biomass contributes 4.99 GW (1.61%). In view of this, present study has made an attempt to have a brief review on various categories of biomass and its resources available in the Indian context and its wide range of applications based on the process of conversion methods or technologies used. Study also brings various possibilities of using different biomasses and their suitability in the context of energy resource.

Kunal Arora | Harsh Kansal, Krishna Murari , Hitesh Mittal, Sumit Kumar

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.

A study on the pH Value of Fly Ash Concretes

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

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..

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.

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.

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.

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.

Somaling Koti | Dr. S S Desai, Dr. V Ramesh

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

T.S. Lakshmi | K. Gunasekaran,K.S. Satyanarayanan

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.

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.

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 of Flow Structure by Varying Divergence Angle and Contour of Supersonic C-D Nozzles

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

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.

Analysis of Surface Roughness and Delamination of Sheet Moulding Composite (SMC) During End Milling Using Taguchi Method

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.

Application of Polypropylene Fibre as a Reinforced Concrete

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

Saurav Jyoti Parasor | 

Abstract

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

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

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 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

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.

SanthoshGaidhankar | SanjayCK, Vishwas SK, Subhashith KV, Mr.Shashank KS

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.

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.

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

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.

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

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

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.

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.

Design and Numerical simulation of Partial Flow Isokinetic Dilution Tunnel for Diesel Particulate Measurement

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

Jitendra N. Gangwar | Samir Saraswati

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.

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

Rashin Nath.KK | Jayee K Varghese

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

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

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. The input pressure, output pressure, input velocity, exit velocity, torque, actual work, isentropic work, experimental efficiency and power were calculated from the model and the designed turbine, when running on compressed air. The equations used for these calculations are the Navier-Stokes equation in cylindrical co-ordinate system, continuity equation, momentum equation. These were the theoretical calculations done on the model and the designed turbine. The Bernoulli’s equation, continuity equation, torque equation in relation with fluid flow, angular acceleration are calculated manually for the values of torque, isentropic work, actual work and experimental efficiency.

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

Jennifer Jacob | Robins Mathew, Somashekhar S Hiremath*, Chandrashekhar Bhat

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.

Abstract

This paper emphasis on the precipitation initiated flooding which is produced by excessive depth rainfall within the city area that is overwhelmed due to improper management of drainage system. Globally water logging is a concern in all developed countries and is playing a vital role in the infrastructure management. It has become part and parcel of mostly all around the world and the good team of researchers and engineers are working to solve this issue but the recurrence of this issue is increasing. This paper speaks about the blue roof network system which has the potential to reduce the peak runoff of storm water and this study examines its potential for controlling drainage overflows through a GIS analysis in H-East ward of Mumbai, India which has been encountering water logging problem from last few decades. The Mumbai's drainage system works on the gravity based system and the end outfall is placed below as well as above the mean sea level based on various criteria such as tidal levels etc. During heavy rains, the high tides create a problem in the drainage system in such a way that the rainwater remains in the sewer and can't be drained out in the streams and this create water logging issues in the nearby vicinity. Flood management measures and study is needed at this point of time and because always space is a constraint in a city like Mumbai, the proposed measures have to be progressive to obtain the desired protection degree with minimal disturbance to the existing conditions. This study finds a solution to this problem by capturing of as much precipitation as possible every time it rains. Through a comprehensive design of control flow device over the conventional drain on the roof terrace of buildings also the study demonstrate herein with a concept of blue roofs network system on every building in the study area would decrease the number of sewer overflow events.

Abstract

Algae’s are the ancient ancestors of all aquatic plants. These algae’s are mainly classified into micro and macro algae groups and these groups combiningly have more than 2,00,000 species. 60-70% of the present day fossil fuel i.e., petroleum is contributed by algae’s. Today’s Fossil fuel energy resources are depleting rapidly and most importantly the liquid fossil fuel will be diminished by the middle of this century. In addition, the fossil fuel is directly related to air pollution, land and water degradation. In these circumstances, biofuels from renewable sources can be an alternative to reduce our dependency on fossil fuel and assist to maintain the healthy global environment and economic sustainability. Production of biofuels from food stock generally consumed by humans or animals can be problematic and the root cause of worldwide dissatisfaction. Biofuels production from microalgae can provide some distinctive advantages such as their rapid growth rate, greenhouse gas fixation ability and high production capacity of lipids. In this regard in the present work we developed a micro algae photo-bioreactor which suits for the operating conditions and cultivation conditions of micro algae to get maximum yields of biofuels in less cost and it can be utilized for both domestic and commercial purposes.

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

Demands for improved productivity, efficiency, and quality pose challenges to the welding industry. As materials become ever more sophisticated in their chemical composition to provide ever-better functionally specific properties, a more complete and precise understanding of how such materials can be joined for optimal effectiveness and efficiency will become essential. Traditional options for welding will surely evolve, sometimes to provide unimagined capabilities. In addition, totally new methods will almost certainly emerge as evolution of materials gives way to revolution to meet unimagined new designs and design demands. The paper considers process systematization and corresponding advances of constituent technologies, discusses some of the role and future direction of welding technology, welding materials, productivity and efficiency, education and safety having an impact on future growth in welding technology. Analysis of drivers and the key needs of some manufacturing industries have been researched, giving general trends and strong indications as to expected trends in technology that will be seen in the future. It also provides a good foundation for future research and creates awareness of the developmental direction of welding processes and materials in manufacturing industries.

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 29th June 2017

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

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

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

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.

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.

Effect of Intermediate Web Stiffener on Buckling Behavior of Axially Loaded C-Lipped Cold-Formed Sections

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.

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 Particle Packing of Aggregates on properties on High Performance Concrete (HPC)

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

Shinde Rohit Vijay | Prof. Ashita J. Sheth

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.

Bhiksha Gugulothu | A. Raveendra, M.Uma mahesh

Abstract

Good surface quality and better material removal rate are desired for the proper functioning of the produced parts. It was seen that the desired surface roughness and material removal rate were not obtained consistently in turning of EN 8 steel applications (Camshaft). These higher values of surface roughness results in rework and increases cost hence the main objective is optimization of surface roughness and material removal rate a general optimization of surface roughness and material removal rate are deemed to be necessary for the most of manufacturing industry The surface quality and material removal rate are influenced by cutting speed, feed rate and depth of cut and many other parameters. In this study the effect of the machining parameters like spindle speed, feed and depth of cut on material removal rate and surface roughness are investigated, also optimum process parameters are studied. An L9 orthogonal array (mixed level design), analysis of variance (ANOVA) and the signal to noise (S/N) ratio are used in this study. Mixed levels of machining parameters are used and experiments are done on conventional lathe machine. EN8 or 080M40 is unalloyed medium carbon steel material is used it is suitable for manufacture of shafts, studs, keys, general purpose axles etc. The most significant parameters for material removal rate are depth of cut, speed and least significant factor for MRR is Feed, For surface roughness speed, depth of cut the most significant parameters and least significant factor for surface roughness is feed

Abstract

There are various technical challenges to be solved in today’s casting technology. For achieving various challenges that to overcome the difficulties faced throughout, for proper mixing or uniform distribution of reinforcements, with base metal/metal matrix is biggest challenge. This affects directly on various factors such as properties and quality of metal matrix composites developed, etc. In the present work a modest/realistic attempt would be made to develop Aluminium based Silicon Carbide composite (AlSiC) with an aim to develop a composites with the conventional low cost, stir casting method/technique has been used and equivalent/subsequent property analysis has been made to develop the composites . Aluminium (a357) having 7%silicon and SiC (100-grit) have been chosen as metal matrix and reinforcement material respectively. Experiments are planned for conducting varying weight fraction of SiC (from 0%-12% in the steps of 3%) while keeping all other parameters like furnace temperatures & total mass of material mixture constant. In this mechanical string is used for proper mixing of silicon carbide in aluminium hot molten metal. The results were evaluated by Tensile test and Brinell Hardness Test (including micro-structure). The trend of Tensile and hardness with increase in weight percentage of SiC were observed and recommendation made for the potential applications accordingly. By this experimental analysis, it is observed that 12% SiC with Aluminium will give the maximum value among the matrix mixture composites prepared.

Abstract

In this study effect of alpha prime (α’) precipitate on the mechanical properties of thermally embrittled DSS has been investigated. Initially as received material was solutionized at 1070 ºC followed by water quenching in order to dissolve if any harmful precipitates were present. Then the samples were thermally embrittled by heating the samples at 475 ºC and water quenched for varying periods from 25 to 750 hours. Tensile and impact toughness tests were performed in order to evaluate the mechanical properties. Microstructure and fractured samples were examined by scanning electron microscope. Results showed that mechanical properties were significantly degraded when subjected to thermal ageing at 475 ºC which is one of the key limiting factor for the usage of Duplex stainless steels in power plants for long term applications. Mechanism behind475 embrittlement was also investigated in this study.

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.

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.

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

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 29th June 2017

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 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.

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

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.

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

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

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.

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

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

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.

Fabrication of Pulverized Pesticide Multiple Sprayers

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

Sachin Anant | Manjunatha k, Mahesh Powar, Nishay K R,Mahesh Kulgeri

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

Laboratory low cycle fatigue tests were conducted on permanent moulded austempered ductile iron alloyed with 1.0% and 2.0% nickel content. Samples were austenitized at 9000C for 60 minutes and austempered at 300 and 3500C for 60 to 150 minutes in steps of 30 minutes. The results indicated that PMADI samples austempered at 3000C for 60 minutes showed superior fatigue strength than other test samples. 2% Nickel PMADI samples showed better fatigue strength than 1% Nickel PMADI samples. The results were analyzed based on structure property correlation and microstructure

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.

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

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.

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.

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

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. Both these laminates are made by hand layup technique and then compressed in a compression moulding machine.

Impact of Regenerative Braking System Using Flywheel

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.

This paper assesses the trans-esterification process for the production of Biodiesel (fatty acid monoalkayl ester) from waste mustard and jatropha oil mixed with methanol (CH3OH) using potassium hydroxide (KOH) as a catalyst at a temperature of 60˚C.As it is a sustainable alternative not only economically, but also environmentally and ecologically to replace petroleum diesel fuel. The most promising alternative fuel will be the fuel that has the greatest impact on society. The major impact areas include wellto- wheel greenhouse gas emissions; non-petroleum feed stocks, well-to-wheel efficiencies, fuel versatility, infrastructure, availability, economics, and safety. Compared to some of the other leading alternative fuel candidates biodiesel appears to have the largest potential impact on society, and should be considered as the fuel of choice for eliminating the dependency on petroleum. With increase in the demand of petroleum products the prices of petrol & diesel are increasing worldwide. Hence biodiesel is alternative sources of energy for running our generators; automobiles etc. are being considered worldwide. In this study, the properties of the waste mustard and jatropha biodiesel produced were compared with ASTM standard and found to be within the limits. Primarily, the utilization of these waste mustard and jatropha oil for biodiesel production will reduce dependency on foreign oil and secondly, this will remove disposal problem of waste sand make environment safe from pollution. The process involves heating of oil followed by titration, then setting and seperation and finally washing.base catalyzed transesterification process is applied

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

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.

S.P.Atpadkar | A.R.Vasatkar

Abstract

In the present days with globalization of Indian economy & introduction of multinationals in India for construction activities, it has become foremost to have speedy construction using new technologies & trends in construction equipments. Construction equipments play a vital role in making the project successful with respect to cost & duration required to complete it. Conventional methods viz. adopting manual handling of materials, excavation, hauling, loading & unloading cannot cope up with demand of infrastructural facilities with high degree of quality control & assurance thus extending the duration of project. Though conventional method proves to be economical but fails in providing required number of dwellings in time. Thus latest construction equipments with new technologies have eliminated these drawbacks thereby permitting speedy excavation, loading, unloading & hauling with reduction in time & labor cost. Thus it has become an important task to develop the automated services in this sector too whereby it will be covered by studying, classifying & detailing the construction equipments.

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.

Abstract

In the modern techniques of the concrete formation there is a lot of interest in increasing amount of microfine particles (<75μm) in aggregates and it is important to understand their effect, including clay and nonclay mineralogy. The present study concentrates on extenuating the influence of fines and microfines on properties of concrete. Generally the sand used in construction industry in major metro cities is of manufactured type, which is obtained by mechanically crushing aggregates in washed or unwashed condition. After washing too some silt impurities remain in the sand and this study is carried out to understand their influence in high performance concrete (HPC). The study is carried out by preparing trial mixes, by adding 1% to 10% silt in washed manufactured sand by weight of sand for M-60 grade of concrete mix. For each trial mix workability, compressive strength, water permeability, rapid chloride penetration test, modulus of Elasticity tests are carried out as per given IS specifications to understand optimum percentage of silt should be present in the concrete, and its effect as the impurities are increased. The study confirmed that the extent of silt content decreases the workability and compressive strength of concrete

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

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

Introduction to Gemba Kaizen in Construction Industry

Aditya Kumar Singh | 

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.

Dr.Manohar H S | Lakshmikanth C, Puneeth Kumar M V

Abstract

Nano-metal-matrix composites (NMCs) are novel composite materials in which nano-phase such as nanoparticles, nano-rods, nano-structured materials are reinforced with metals or alloys to improve the physical, mechanical, wear and other properties.In the present study, Al6061 alloy has been chosen and used as the matrix material and nanoclay as the reinforcement. Composites were prepared by using liquid metallurgical rout (stir casting method) nanoclay particle content was increased from 0 to 20 % in steps of 5% by weight Corrosive erosive wear test was conducted on Al-Nanoclay metal matrix by corrosive-erosive wear tester. 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

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

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.

Sharad N. Koyale | Ruturaj N. Londhe,Vaibhav G. Talandage

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.

Investigation of In-Plane and Out-of-Plane Buckling of Tied Arch

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

Investigation on Age Hardening of Aluminium Alloy using Biological Quench ants

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 3rd October 2017

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.

Investigation on Machining of Silica Wafer Using Developed Micro-Electrical Discharge Machining (μ-EDM)

International Journal of Engineering Research in Mechanical and Civil Engineering, Available online 1st November 2017

K. Aruna | Somashekhar S. Hiremath

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.

Investigation on the Benefits of Cryogenic Treatment on Tungsten Carbide Tool Inserts in Machining C-45 Steel

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

R.G.Deshpande | K.A.Venugopal, H.V Panchakshari

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.

Abstract

Keeloq code hopping technology incorporates high security, a small package outline and low cost. This technology is incorporated in keeloq encoders such as HCS300 family and keeloq decoders such as HCS500 family which makes these devices a perfect solution for unidirectional remote keyless entry systems and access controls systems. Keeloq encryption and decryption algorithms in encoders and decoders respectively generate a unique code for every new transmission, i.e. when the user presses a button. Thus rendering code capture and resend schemes useless Keeloq is used in majority of remote keyless entry systems by companies as Daewoo, fiat, Honda, GM, Toyota, Volvo etc. The light-weight architecture of the KeeLoq cipher allows for an extremely low-cost and efficient hardware implementation. This contributed to the popularity of the KeeLoq cipher among designers of remote keyless entry systems, automotive and burglar alarm systems, automotive immobilizers, gate and garage door openers, identity tokens, component identification systems. For instance, the KeeLoq block cipher is used in the HomeLink wireless control systems to secure communication with some garage door openers. The KeeLoq technology supplied by Microchip Technology Inc. includes the KeeLoq cipher and a number of authentication protocols.

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

Measuring Shear wave velocity using MASW method and determining its use in Construction Engineering field

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

Mechanical Properties of Concrete Mixed and Cured with Treated Domestic Waste Water

Sourab M | B B Das , Arun Kumar Thalla

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

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

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. Both these laminates are made by hand layup technique and then compressed in a compression moulding machine.

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

Abstract

In and around the offshore industry, there are drastic developments in the construction of structures as well as in the analysis. In the design and analysis of most of the offshore structures, effect of other obstructions in the field is considered as a minor factor. But there is some influence on the force acting on the structures due to the presence of other neibouring structures. The concept of bluff bodies which is characterized by large amount of flow separation in the field of offshore structures. This work mainly focuses on the flow past bluff bodies. A 2-Dimensional steady state is considered for the simulation in the computational fluid dynamics. The flow domain considered is rectangular with appropriate boundary conditions.

Abstract

Concrete composite slabs with precast concrete deck and cast-in-place topping is used extensively in construction industry now a day as it reduces the construction time, eliminates the formwork usage and ensures good quality of construction. The composite action between the segments depends on interfacial shear resistance between the segments which in turn depends on the interface parameters such as cohesion, friction and area of shear connectors. Push-off test is used to evaluate the interfacial shear resistance of concrete composite members. In the present study, L shaped push-off test specimen details reported in the literature is taken up for numerical investigation. A 3D solid modelling of L-shaped push-off specimen is carried out. The concrete part of the specimen is modelled using solid finite element. The material model for concrete could simulate concrete cracking, crushing, and crack closure. The fracture characteristics of concrete are modelled by an orthotropic smeared crack model based on the Rankine’s theory. The reinforcement bar is modelled using line element. The material model for reinforcement steel uses a bilinear elasto-plastic model with hardening. The interface is modelled using a zero length gap element. The interface material model is based on Mohr-coulomb criteria with tension cut off. The nonlinear finite element analysis of the push-off specimen is carried out and validated with the reported results. It is found that the finite element results corroborate with the reported experimental results

Abstract

Bird strike, being a catastrophic problem, has led to many horrendous accidents throughout the world in aviation industry. To get over this problem, a lot of research has been done in the past and still new materials and their combinations are being explored for minimal damage under such accidents. In the present work, an attempt has been made to numerically simulate the bird strike on curved plate where bird is simulated using a projectile and curved plate acts as a part of nose of an airplane. In the present investigation, plate is made of aluminum alloy (7075-T6). This alloy is most commonly used in aviation industry due to its high strength to weight ratio, machinability and relatively low cost. Numerical simulation is carried out using commercially available Finite Element (FE) package ABAQUS®. Herein, three birds namely, herring gull, golden eagle, and Canadian geese are studied for considering the effect of mass and size of the bird. In this numerical simulation, sizes and mass of these three birds are chosen due to their frequent strike in many parts of the world. Each bird is given three different velocities and their impact on curved plate are studied considering the effect of variation of mass, plate thickness and velocity. A simpler approach is applied to numerically simulate the complicated phenomenon of bird strike. The results show that with increase in mass and velocity, damage on the curved plate increases whereas, increase in thickness of plate resulteds in reduced damage.

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

Dony Dominic | G. Venugopal

Abstract

Metal hydrides have been prompted as one of the most promising materials for hydrogen storage applications. The key challenges confronted with hydrogen storage using metal hydrides are to minimize the time of absorption and maximize the amount of hydrogen storage. The objectives of the present study are (i) to develop relationship between operating and design variables and (ii) predict, numerically, the performance of metal hydride system. The governing transport equations are solved with a fully implicit finite volume numerical scheme with the commercial software FLUENT. The heat transfer analysis of the metal hydride bed underlines that thermal conductivity of the bed material plays a significant role in the hydrogen absorption characteristics of the bed. Further, the study has lead to propose a new design of hydride bed with the inclusion of aluminium layers inside the LaNi5 hydride bed. The numerical analysis was further extended to study effect of wall thermal boundary conditions on absorption characteristics the of metal hydride bed. The results show that better heat transmission and reduction in time for charging is possible with the proposed new design of metal hydride bed.

Abstract

Sustainability is one of the key issues these days almost all around the world and has drawn attention in any major construction projects. In recent past years, there is significant gap between demand and supply of construction materials. In one hand, natural resources are being depleted rapidly to meet this demand leading to environmental imbalance. On the other hand, huge amount of construction and demolition (C&D) waste is being generated every year and disposed into open land leading to useful space reduction thereby enhancing level of environmental hazards. That’s why C & D waste has drawn attention of the investigators. Studies have been performed considering C&D waste as the potential coarse aggregate replacing natural resources for the purpose of producing concrete. Various initiatives e.g. Smart Cities Projects, Swachh Bharat Mission etc. proposed /taken up by Government of India have made Indian construction industries to go for sustainable construction techniques in order to achieve the sustainable growth in construction sector. This paper has reviewed different aspects of C&D waste generated in India and brings out effective utilization of the same towards possible future sustainable growth in the construction industry.

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

Koci DORACI | Alfred HASANAJ

Abstract

this paper objective is to contribute in the optimization of the problem of guiding forces during the movement of the railway vehicle. The work proposes an innovative solution as compared to classical author suggestions which are limited to a small number of alternatives. Methodology follows an experimental approach. An experiment with two stages takes place where experimental conditions are modeled after profiles designed following a curved path with 500 m radius (classified as tight curve by definition). In the first experimental stage standard profiles were used, while for the second experimental stage curvilinear profiles were exploited. After experiment conduction data concerning (1) displacement (2) moments of force and (3) guiding forces of wheel-rail contact were analyzed and compared for both stages: standard profiles and curvilinear profiles After experimental results, major conclusions of the paper are: (1) in the case of curvilinear profiles profile, small movements of vehicle, lead to a change in the size of the wheel displacement smaller than the corresponding change in standard profiles; (2) moments of force are greater in the case of standard profiles compared to curvilinear ones; and (3) curvilinear profiles enable a movement without many contact point with the wheel, friction forces exert their action in longitudinal direction, thus by causing a smaller value of guiding forces.

Abstract

From past few years as the construction activity is increased by and large, production of cement to fulfill the constructional need has resulted in depletion of natural resources causing environmental problems. The use of supplementary cement materials and fillers become imperative due to the increase in cost of cement and its limitations in terms of high energy requirement for production, high carbon dioxide emission and large consumption of natural resources. Many alternative materials such as fly ash, GGBS, silica fume, lime powder ect. There is a scarcity of fine aggregate (river sand) in the developing countries like India. The present study shows the incorporation of fly ash and slag aggregate as partial replacement for cement and fine aggregate in the proportion of 10%, 20%, 30%, 40% and 20%, 30%, 40%, 50% respectively. The factors selected were water cement ratio, fly ash to cement ratio, slag sand to fine aggregate ratio and 4 levels for each was considered, the w/c levels are 0.30,0.33,0.36 and 0.39 and the levels of other factors are as specified above. By using the Taguchi method of optimization the experimental combinations were reduced to 16 by selecting a L16 orthogonal array. The freshened and hardened properties of concrete were examined at 7 days, 28 days. The test results indicates that the highest strength of concrete is obtained by replacing 10% of cement by fly ash, 20% of fine aggregate by slag sand with a water cement ratio of 0.3. The regression analysis was done for the obtained results.

Vaikunth B | Kaarthik E, Varadharaj Rathinam A

Abstract

The thermal efficiency of heat engines can be improved using Rapid Pressure Swing adsorption technique (RPSA). This technique employs insertion of pure Oxygen into the combustion chamber of IC engines. This air-fuel mixture is similar to stoichiometric mixture. Atmospheric air is removed of its Nitrogen before sending it into the intake manifold using adsorbing materials such as Zeolite, Carbon etc. This technique decreases the amount of fuel supplied for each stroke and hence aiding in fuel consumption. This method also reduces the emission of Carbon Monoxide and Nitrogen Oxides (NOX) thus contributing to a greener environment. This process also ensures complete combustion of fuel.

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.

Abstract

All industries mainly concentrate on increasing the quality of its products and increasing its profit. The profit can be increased by using various strategies; one of such strategies is increasing the productivity of the plant. The industry where the project work has been carried out is one of the leading steel producing industries in India. In steel making industries, increasing the productivity can be done by various means; one of such is reducing the steel tap to tap time (cycle time) at basic oxygen furnace shops. Cycle time is the total time from the beginning to the end of any process which includes process time, during which a unit is acted upon to bring it closer to an output, delay time, during which a unit of work is spent waiting to take the next action and sometimes maintenance operations. The main goal of the project is to minimise the Cycle time which in turn increases the productivity. The project has been carried out in three steps. First step is to understand the actual processes and delays present in a cycle and the time taken by these processes. The next step is to collect the data regarding the time taken by the actual processes, maintenance operations and the delays in between the actual processes. In this step data were taken for about 100 heats. In the final step the data taken are analyzed and where the maximum delays occurring are identified. The special attention is given to maintenance operation timings that to carry out some of them simultaneously which will reduce average cycle time.

Vasagade Vijay Ganapati | Udgave Ashish S,Zalake Anjali, Patil Sachin R., Nejkar Harshal

Abstract

One of important part in coupling is trunion which is a part of rotating joint where shaft is inserted into. This allows precise tolerances to be maintained along with large surface in contact, so that power is transferred efficiently. Hence there is a vital role of trunion in transmission which outlines the efficiency of transmission system and power transfer is also affected by it.Hence it is necessary to do detail study and analysis of transmission coupling withtrunion. To overcome the certainlimitations like excess strain on joint, wearing of joint, Thompson type constant velocity joint (CV) or Thompson coupling with trunion joint is considered under the optimization study ,which may offer features like minimizing side loads, higher misalignment capabilities, more operating speeds, improved efficiency of transmission and many more. This work presents comparative study for optimization of Thompson type coupling for angular transmission with Phosphor Bronze and Brass material for trunion joint over conventional Alloy steel. 2015 The Authors.

Abstract

Generally a bituminous mixture is a mixture of coarse aggregate, fine aggregate, filler and Binder. Hot Mix Asphalt is a bituminous mixture where all constituents are mixed, placed and compacted at high temperature. HMA can be Dense Graded mixes (DGM) known as Bituminous Concrete (BC). In the present study, an attempt has been made to study the effects of use of Synthetic fiber called Polypropylene fiber as an additive in BC. For preparation of the mixes aggregate gradation has been taken as per MORTH specification, binder content has been varied regularly from 5% to 7% and fiber content Varied from 1% to maximum 9% of total mix. Using Marshall Procedure Optimum Fiber Content (OFC) and Optimum bitumen Content (OBC) are arrived at for BC mixes. The BC prepared at OBC and OFC are subjected to different performance tests like Marshall Stability, Marshall Flow, unit weight, Air Void, Void in Mineral Aggregate (VMA) and Void Filled with Bitumen (VFB). The results indicated that adding (5%) of the Synthetic fiber by the total weight of Bitumen with (12mm) length increases Marshall stability value as compared with the conventional mix.

Parametric Study and Optimization Along With Selection of Optimal Solution in Die Sinking Electrical Discharge Machining of Tungsten Carbide with Taguchi Hybrid Approach: A Review

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

Parametric Study and Optimization Along With Selection of Optimal Solution in Die Sinking Electrical Discharge Machining of Tungsten Carbide with Taguchi Hybrid Approach: A Review

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

Aman Deep | Mr. Raj Kumar

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

The RC frame with bracings is an efficient and economical method to resist the lateral forces acting on the structure. Under the seismic loading, the conventional steel bracings buckle due to compression. Buckling restrained braces are the innovative bracing systems which show same load deformation behaviour under both compression and tension. Aim of this study is to compare the conventional steel braces and buckling restrained braces considering a 10 storey RC frame for different configuration of braces. The analysis is performed using commercially available software ETABSv2016. For different configuration of braces the response spectrum analysis is performed and the parameters such as storey drifts and base shear are evaluated for all type of bracing configuration. From the study it is concluded that BRB with the X bracings arranged in central bay perform better during earthquake event

Partial Replacement of Cement By Bone Ash

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

Dr.A.S.Kanagalakshmi | J.Vindhya

Abstract

Bone mineral is a complex chemical made up of calcium which can be used as a partial replacement for cement in concrete structures. Since the amount of carbon di oxide released during the manufacturing of cement. In order to reduce the carbon di oxide, bone ash can be used as an effective replacement of cement. This study investigated replacement of bone ash varying from 5%-20% in a mix of 1:1.5:3. The compressive strength of the cubes casted was tested and the results show that ,when the replacement is 10% then the strength of concrete is more than the actual strength. Whereas the specific gravity of bone ash in only 1.59 and hence the mixing should be done in volume basis. The results suggests that workability was within the safe permissible limit but the compressive strength of concrete dropped but it was also within the safe permissible limits for light weight concrete. The replacement of bone ash should not be more than 10%.

Rahul Patil | RajatBhujade ,RohitRaut ,RoshanDhok

Abstract

In the present era energy saving and sustainable development, several researches and projects have been conducted on how to create low cost and eco-friendly constructional materials. One such natural material is coconut. The selection of coconut is done due to its several important properties. These properties includes water resistance, durability against acids, alkalines and salts. It contains low cellulose conte0nt which helps to absorb less water which reduces its weight. The coconut shells are also non-bio degradable. It does not require pre-treatment. In the coming future the demand of crushed coarse aggregate may increase and it’s a urgent need to find an alternative to it. The use of crushed coconut as coarse aggregate will create a light weight concrete reducing the self weight of the concrete. The coconut shell may present itself as a economical and potential material for creating a proper mix design. The test for partial replacement of coarse aggregate are obtained by using split tensile strength and compressive strength test. For these test cubes of dimensions 0.15m x 0.15mx 0.15mand cylinder of dimension0.15m x 0.3m. The test results obtained are compared with nominal mix cube and cylinder. Hence our aim is to empower the issues related to the reduction of conventional material and proper usage of increasing waste material and its disposal by making the coconut shell concrete as light weight, durable CIVIL ENGINEERING MATERIAL.

Particle Swarm Based Crack detection in Structure using One Dimensional PZT Patch Model

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

N. Jinesh | K.Shankar

Abstract

The concept of damage identification scheme for single/multiple crack in beam is presented, based on one dimensional Piezo Electric ZirconiumTtitanium (PZT) patch with beam model. Hybrid element constituted of one dimensional beam element and a PZT sensor is used with reduced material properties. The Finite Element Model (FEM) model of hybrid element constituted of beam and a PZT sensor is formulated based on One Dimensional approach. The reduced piezoelectric stiffness, coupling and dielectric properties are used for the PZT patch sensor. The Crack Identification is posed as an inverse problem whereby unknown crack parameters(depth and location) are identified by minimizing Objective function of the mean square of the deviation between predicted and measured voltage response obtained from the PZT patches. A non-classical heuristic Particle Swarm Optimization (PSO) is used to minimize this objective function. Using fracture mechanics concept, crack is modeled as a hinge which provides an additional flexibility to the element and cracked stiffness matrices are formulated based on FEM procedure. In the proposed method, PZT patches are attached to either end of the concerned beam. This model is convenient and simple for identification of beams. The signals are polluted with 5% Gaussian noise to simulate experimental data. The feasibility of the proposed approach is proved by numerical studies on a beam with single and double crack per element.

Abstract

A Water system includes a reciprocating pump operated by pedaling power. The pump set and includes a housing in which a foot pedal and drive shaft rotate an eccentric pin rotating with the drive shaft moves a connecting rod which in turn causes push rod to move linearly. The pushrod extends into a pressure tight chamber formed above the rising main. A pump rod connected to the push-rod extends to the conventional plunger through verified motion. Here we use the foot pedal pump, powered by our legs instead of arms to lift the water from a depth range of seven meters. Throughout history human, energy has generally been applied through the use of the arms, hands, and back. With minor exceptions, it was only with the invention of the sliding-seat rowing shell, and particularly of the bicycle, that legs also began to be considered as a normal means of developing power from human muscles A person can generate four times more (1/4 horse power (hp)) by pedaling than by hand cranking. At the rate of 1/4hp, continuous pedaling can be done for only short periods, about 10 minutes. However, pedaling at half this power (1/8 hp) can be sustained for around 60 minutes. The main use of pedal power today is still for bicycling at least in the high- power range (75 watts and above of mechanical power). In the lower-power range there are a number of use of pedal power for agriculture, construction, water pumping, and electrical generation that seem to be potentially advantages, at least when electrical or internalcombustion engine power is unavailable or very expensive.

The aim of the seismic design is to protect the important building such as museums, hospitals, official buildings etc.., and reduce the damages after a seismic event. Many researchers have done a lot of research to get the best solutions to resist earthquakes and protect survival. One of those solutions is base isolation, the main goal of seismic isolation is to shift the fundamental frequency of a structure away from the dominant frequencies of earthquake ground motion and the fundamental frequency of the fixed base-superstructure, the other purpose of an isolation system is to provide an additional means of energy dissipation, thereby reducing the transmitted acceleration into the superstructure. In the present study, a five-story RCC building has been designed and analyzed according to IS Code for seismic analysis by (ETABS-2015) software using time history analysis, the study considered two models one of the models represents conventional building and the second model represents base isolation (BI) building. Results show that the model of base isolation reduces meaningfully the moment and shear produced for the same mode and hence reinforcement required is lesser compared with the fixed-base model, the results also show that the modal period increases in BI model subsequently, displacement is higher in this model than fixed base model because of flexibility of base isolation building.

Abstract

Homogeneous Charge Compression Ignition is the mode of engine which will provide the advantages of both the SI and CI engine and consider as an alternative to the gasoline and diesel engine due to its capability of very low NOX emissions and operating with higher efficiency. The HCCI concept involves pre-mixing of charge prior to its induction as in present Spark Ignition (SI) engine, then ignite the air fuel mixture through the compression as in Compression Ignition (CI) engine and has no throt tle loss, which leads to high efficiency. HCCI engine can operate on gasoline, diesel and most of the alternatives fuels. In HCCI, the combustion occurs simultaneously throughout the cylinder volume, as opposed to the turbulent flame propagation or mixing controlled combustion used in conventional engines. Instead of having advantages there are some challenges to the operation of the HCCI Engine. The main limitation of HCCI is the narrow operating window which results from the lack of direct ignition timing control. This paper reviews the technology involved in HCCI engine development, its advantages and disadvantages. The challenges involved in HCCI and the future developments in the same are also discussed in the paper.

Abstract

In today’s world one of the major concerns is the limited amount of fuels available with mankind. The decreasing amount of fuels has resulted in a major increase in price also they give higher air pollution. Diesel is one of the most used fuels across the world due to its higher efficiency. This report presents an attempt of using the blends of Bio Diesel to reduce a cost and emissions of a diesel engine without compromising on higher efficiency as diesel fuel. The source of the fuel generated is Mahua Oil which is non-edible oil. We have used double trans esterification process to produce biodiesel. Steps used in the production of Biodiesel were concentrated on optimizing the amount of biodiesel produced. The biodiesel blends with different quantity were tested on an experimental diesel engine setup. The major concern here was to run a production engine without any modification safely. The type of emissions produced in the blended sample and diesel sample are compared and performance also compared. Emissions were measured with gas analyser as well as smoke meter. From this it has been found that HC, NOx and CO emissions are reduced in B5 and B10 fuel compared with pure diesel without much compromising on performance.

Abstract

Magnetic field generated by a permanent neodymium magnet of 4,000 gauss intensity was used for this research and was applied on the fuel line of a 3 cylinder,4-stroke SI engine to reduce the fuel consumption and even the pollutants of the exhaust gas. This research comprises of various trials conducted on the engine at 3,000 rpm and different loads (100%, 80%, 60%, 40%, 20% and no load). Firstly, the engine was run without the installation of the magnetizer and all the performance parameters and the exhaust gas readings were noted down, and then the same procedure was adopted after installing the magnetizer just before the carburetor. The trials had positive results with maximum of 7.5% decrease in specific fuel consumption and about 4% increase in both mechanical efficiency and brake thermal efficiency. It was also found that there was a significant decrease in exhaust gas emissions with maximum amount of decrease in Carbon monoxide and Hydrocarbons was about 3% and 6% respectively, while there was an increase in Carbon dioxide by about 2%. The results above states that this technique helps in improving the performance and thereby saving the fuel and enhancing the green technology.

Abstract

The increased attention on alternative fuels in the recent years was mainly driven by increasing oil prices, strong emission norms and the concern on clean environment. The biodiesel has emerged as a potential substitute for diesel fuel on the amount of its renewable source and lesser emissions. In order to increase the swirl in the combustion chamber, we are redesigning the piston crown with elliptical shaped grooves over it. The present research is aimed to investigate experimentally the performance and exhaust emission characteristics of a direct injection compression ignition engine equipped with a redesigned piston crown fuelled with conventional diesel fuel, blend of diesel and rice bran oil biodiesel, and blends of diesel and rice bran oil biodiesel with varying proportions of zinc oxide nano materials as additives over the entire range of load on the engine. The piston in the diesel engine is replaced and then fuelled with the above said fuels. The performance parameters such as brake power, specific fuel consumption, thermal efficiencies are calculated based on the experimental analysis and engine emissions such as CO, HC, CO2 , and NOx emissions are measured. The data has been analyzed and the results are presented and discussed in this project.

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

Sreekanth Palla | M. D. Goel

Abstract

Structural engineering strategies can improve the blast resisting capacity of the elements. Blast resistance performance of elements can also be improved by varying geometry of the elements. In the present investigation, dynamic analysis of steel sacrificial blast wall is carried out with varying angle of curvature and thickness of wall. Three-dimensional nonlinear dynamic analysis of steel wall under blast loading has been carried out using ABAQUS® finite element package. Trapezoidal impulse with uniform pressure has been considered for defining blast loading. Performance of wall is compared with equivalent triangular loading to understand the effect on peak deflection. Three-dimensional deformable shell element (S4R i.e. 4-noded doubly curved thin or thick shell, reduced integration, hourglass control and finite membrane strains) has been used for FE analysis of wall. Analysis has been carried out with varying angle of curvature along top one-fourth length of wall. Performance of curved walls is compared with that of straight vertical wall in terms of peak deflection. Further, effect of thickness of wall, on the blast resistance, has been investigated. Deflection at various points along the height of wall and strain energy curves of wall are also computed and analyzed. From the present analysis, it is observed that variation in angle of curvature of wall results in considerable improvement in performance of wall against blast loading. Models with trapezoidal blast loading and equivalent triangular loading shows almost similar results. Increase in thickness of wall results in reduced deflection against blast loading.

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

Bhargav K | Ajith Kumar S, Arunan Balajee K A

Abstract

Reduction of energy consumption is a major concern in vapour compression cooling systems, especially in areas with very hot weather conditions. In the hot weather conditions performance of these systems decrease sharply and electrical power consumption increases considerably. Evaporative condensers enhance the heat rejection process by using the cooling effect of evaporation and therefore improve energy usage efficiency. Increasing the co-efficient of performance (COP) of the residential air conditioner with air-cooled condenser is a challenging problem especially in areas with very hot conditions. Applications of solar energy assisted evaporatively cooled air condenser instead of air cooled condenser is proposed in this project work as an efficient way to solve the problem. Experimental results show that the inlet air temperature for evaporatively cooled condenser has been reduced by 3.02% compared to air cooled condenser. Also the time taken for the compressor to cut off has been reduced for evaporatively cooled condenser by 69.5 % (flow rate 8.5L/min; temperature range=22-20 °C) compared to conventional air conditioner

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

Rajendra Patil | Rupesh Gawande

Abstract

A forced convection Hohenheim type of solar tunnel dryer incorporated with sensible heat storage material has been developed to test its performance for drying of tomatoes under the environmental conditions of Wardha, Nagpur India. The purpose of present work is to study a forced convection (PV powered) Hohenheim STD with and without the integration of heat storage material. Thermal bricks (Cp =840J/Kg) were used as a heat storage media. Both tests have been carried out for the same mass of commodity and almost for same environmental conditions. Hourly values of global solar insolation and some meteorological data (temperature, relative humidity, wind speed etc.) have been recorded. Experiments were performed at varying mass flow rates ; varying from 0.023 to 0.038 kg/s and 0.025 to 0.036 kg/s with and without HSM. A uniform air temperature in the collector was observed with integration of heat storage material thus provides continuous drying. The Hohenheim STD with heat storage material is capable of producing an average temperature of 62.5 0C, which is suitable for dehydrating most of agro products; while an average temperature of 54.4 0C was recorded in dryer without use of heat storage media. The equilibrium moisture content for tomatoes was reached after 330 and 370 minutes when the system was used with and without heat storage material respectively. Therefore, the heat storage material reduced the drying time by 40 minutes and also increases thermal efficiency of dryer by 2.8 %. The quality of dried tomatoes in term of color, flavor, texture and time required for drying was favorable as compared to open sun drying and forced convection drying without heat storage material. However the performance of dryer can be increased by increasing loading rate and minimizing heat loss to surrounding

P. Jaya Prakash | Dr. S. Sunil Kumar Reddy

Abstract

The depleting of fossil fuels has simulated the worldwide search for the alternate fuels. AS our country is an agricultural based one and large amount of land is available, production of Jatropha biodiesel will be more advantageous for our farmers. The Jatropha biodiesel is a perfect replacement to diesel because this is derived from indigenous sources and is renewable. But due to its high viscosity and lower calorific value it cannot be directly used in the diesel engine without major modifications to the engine. Hence in the present work it is planned accordingly to use the combination of diesel and biodiesel in the ratio of 80% diesel and 20% Jatropha (B20). The combustion of the engine depends on the flow capability of the fuel. With the higher viscosity, Jatropha oil fluidity will be less and this can be improved with the addition of nano additives. Further the investigation is planned to study the effect of Aluminum Oxide Nano particles as additive on the performance and emission characteristics of Jatropha biodiesel blend(B20). It is blended with Aluminum Oxide Nano particle in mass fraction of 50 PPM,100 PPM and 150PPM.The whole investigation is carried out in a constant speed vertical cylinder water cooled DI Diesel Engine. The performance parameters are analyzed and the results are presented. Aluminum oxide nano particles act as an oxygen buffer which improves the combustion results in increase the Brake thermal efficiency and reduction in the Exhaust emissions

Abstract

The aim of project is making concrete on the cost of making ecofriendly relation and also reducing overall cost of the project and improve the workability and strength. Construction is a major economic activity. In India, it accounts for over 6% of Gross Domestic Product (GDP). A construction project has to deal with environmental aspects. The threat of global warming is real. According to a report by Environmental Protection Agency (EPA) of the U.S.A. Greenhouse gases are accumulating in the earth’s atmosphere as a result of human activities, causing global mean surface temperatures and sub-surface ocean temperatures to rise. With the cost of construction increasing rapidly, today the industry demands that the concrete used for building structures should not only have high strength but also have high durability. Traditionally, construction activities have relied on using normal Portland cement. Production of one tone of normal Portland cement releases approximately one tone of CO2 into the atmosphere it decreases amount of natural resources. There are many supplementary cementitious materials (SCM) used in producing concrete, like, Fly Ash, Ground Granulated Blast Furnace Slag it would help conserve natural resources. It would also save energy required for producing normal Portland cement, help the cause of environment, provide superior concrete structures and benefit the clients. We will make different combination of cement by adding different proportion of GGBS and Fly Ash. we have to calculate optimum dry density of these different proportion for this, each proportion of cement is physical hand mix in dry start and put in Dry Loose Bulk Density Flask (DLBT). These are different combination of DLBT flask available such as 3, 15,30lit after we have to calculation the optimum dry density for each proportion. And the strength is calculated for each of the mix. Curing is done by placing specimens at room temperature. The specimen are then tested at the interval of 7, 14 and 28 days, it includes compressive strength, Water permeability test, Modulus of elasticity and Rapid chloride penetration test.

Abstract

The novel design and experimentation on solar collector system which could utilize the direct solar radiations with two different specific heat capacity heat transfer fluids. This economical point focusing reflector and receiver model of dryer and steam generator may be implemented in industries when scaled up. The parabolic reflector with aperture area of 12m2 and multi cavity receiver filled with SiC ceramic beads are fabricated to concentrate and absorb the heat flux from the Direct Normal Irradiation (DNI).Water is circulated by a pump through copper coil around the receive as high specific heat capacity HTF, Whereas Air is the another working fluid of low specific heat capacity, which is sucked from the atmosphere through the drilled holes of the receiver by a induced draft fan. The heat transfer parameters of both working fluids were experimented for five days, while both fluids are flowing in same time and also while flowing separately with same period of time and almost for the same concentrated solar power. The experimental results on the efficiency of the receiver have no major variations, which reveal the possibilities of applications of air drier and steam generator with the same reflector and receiver areas by two different HTFs of varying specific heat capacities. The receiver thermal efficiencies are maintained in between 72.76% to 74.56% for both the heat transfer fluids with uniform heat flux distribution and heat transfer.

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

Yadhu Krishnan K S | Dr. A Ramesh, Tennison K Jose

Abstract

Only one third of the total fuel energy supplied to the conventional IC engine is converted to useful work, whereas a major part of the energy input is rejected to the exhaust gas and the cooling system. The idea of a low heat rejection (LHR) engine also called ‘‘adiabatic engine” was introduced in its potential for improving engine thermal efficiency by reducing the heat losses. In this study, the LHR operating condition is implemented by increasing the engine coolant temperature (ECT). Experimentally, the engine is operated at varying ECTs of 25°C, 50° C, 70° C and 90ᴼ C in an effort to get trend-wise behavior without exceeding safe ECTs. And performance, emission and exergy analysis were conducted on the engine. The study uses a single cylinder Mitsubishi Kubota diesel engine operating at 1500 rpm to examine the cases having different ECTs. The study revealed that increasing ECT yields improvements in performance and emission characteristics of the engine while an increase in NOx emission was observed.

AnanduMadhavan | prof. Manoj PJ

Abstract

Friction Stir welding (FSW) is a solid state joining process widely accepted to weld difficult to weld materials such as Aluminium. Although the technique is indented to weld Aluminium alloys the process is extended to achieve better joint properties in Steel, Copper, Magnesium and other materials. Friction between the tool surface and work piece surface generate the heat necessary to bring the material to plastic state and then material is stirred to make the joint. The heat generation and material flow in the weld zone depends mainly on the tool Rotation speed, Welding/Traverse speed and Tool Geometry. In this work the fundamental understanding of the FSW process and the effects of these parameters in the joint strength of Aluminium 6061alloy plates is presented. The process parameters are selected according to Taguchi Method, which is an effective and efficient method to optimize the response variable. According to Taguchi orthogonal array the parameters and their levels are selected and the experiments are conducted. The joint is tested for its Ultimate Tensile Strength in UTM. The Rockwell Hardness at various positions in the weld is checked. Microstructure Analysis of the weld zone justify the variations in strength for different welds. Finally the process parameters for Friction Stir welding of Aluminium Alloy 6061 are optimized for maximum strength

Abstract

Sangli city bus stand is a public transport facility intended to commence or terminate local and long journey through Maharashtra State Transport Corporation. It is one of the most crowded bus stands to meet public transportation facilities. Also it is a micro region where number of buses commences, terminate, park, idle as well as accelerate and decelerate. To meet running population demand and to achieve smooth public transport facility it is required to increase number and frequency of transit buses. It results in increase in concentration of pollutants, as most of the buses are propelled by heavy-duty diesel engines which are the major contributors to vehicular pollution. The bus stand is located in heart of city and mostly bounded from all sides except entry and exit way of buses. This causes accumulation of heavy concentration of pollutants emitted by heavy duty-diesel buses and is a major site for common people to suffer from polluted air related health hazards similar to other urban cities. As such automobile induced air pollution at city bus stands is a crucial issue and needs to be attended at earliest. The purpose of this study was to attempt for suitable methodology for quantification of bus emissions generated at Sangli bus stand. This paper reviews number of studies based on transit bus emissions generated at bus stand and also discusses the method adopted for quantification of air pollutants at Sangli city bus stand. The studies conducted at abroad have demonstrated pollution potential of buses. Various researches have suggested change in design layouts and use of alternative fuels to establish the control.

Abstract

This study was aimed to use Gigantia Leaves (GL), Curcuma Longa Leaves (CLL), Morienga Oleifera (MO) and Citrus Sinensis (CS) as a potential adsorbents to remove C.I. Reactive Blue 82 dye from aqueous solution. The adsorption of Reactive Blue 82 on adsorbents was studied as a functions of dose (50-300 g/L), pH solution (2-12), contact time (30 min). The influence of these parameters on the adsorption capacity was studied using the batch process. The corresponding results showed that excellent colour removal of Reactive Blue 82 can be achieved with adsorbents at optimum pH of 2. The maximum colour of Gigantia Leaves, Curcuma Longa Leaves, Morienga Oleifera and Citrus Sinensis was 90.36%, 80%, 75.81% and 70.90% respectively.The experimental data were analyzed by the Langmuir, Freundlich isotherms, Kinetic studies, and Interruption studies. Results show that the data fitted well with the Freundlich isotherm. The kinetics of Reactive Blue 82 adsorption onto adsorbents was examined using the pseudo-first and pseudo-second order.The adsorption kinetics followed the pseudo-second order kinetic modelwhich implies that chemisorption is the rate limiting step. Pore diffusion seems to be the rate controlling in the sorption process as indicated by interruption studies.

Amer Hassan | Shilpa Pal

Abstract

The aim of the seismic design is to protect the important building such as museums, hospitals, official buildings etc.., and reduce the damages after a seismic event. Many researchers have done a lot of research to get the best solutions to resist earthquakes and protect survival. One of those solutions is base isolation, the main goal of seismic isolation is to shift the fundamental frequency of a structure away from the dominant frequencies of earthquake ground motion and the fundamental frequency of the fixed base-superstructure, the other purpose of an isolation system is to provide an additional means of energy dissipation, thereby reducing the transmitted acceleration into the superstructure. In the present study, a five-story RCC building has been designed and analyzed according to IS Code for seismic analysis by (ETABS-2015) software using time history analysis, the study considered two models one of the models represents conventional building and the second model represents base isolation (BI) building. Results show that the model of base isolation reduces meaningfully the moment and shear produced for the same mode and hence reinforcement required is lesser compared with the fixed-base model, the results also show that the modal period increases in BI model subsequently, displacement is higher in this model than fixed base model because of flexibility of base isolation building.

Research and Development of Homogeneous Charge Compression Ignition (HCCI) Engine

Kirtan Aryal | 

Abstract

Homogeneous Charge Compression Ignition is the mode of engine which will provide the advantages of both the SI and CI engine and consider as an alternative to the gasoline and diesel engine due to its capability of very low NOX emissions and operating with higher efficiency. The HCCI concept involves pre-mixing of charge prior to its induction as in present Spark Ignition (SI) engine, then ignite the air fuel mixture through the compression as in Compression Ignition (CI) engine and has no throt tle loss, which leads to high efficiency. HCCI engine can operate on gasoline, diesel and most of the alternatives fuels. In HCCI, the combustion occurs simultaneously throughout the cylinder volume, as opposed to the turbulent flame propagation or mixing controlled combustion used in conventional engines. Instead of having advantages there are some challenges to the operation of the HCCI Engine. The main limitation of HCCI is the narrow operating window which results from the lack of direct ignition timing control. This paper reviews the technology involved in HCCI engine development, its advantages and disadvantages. The challenges involved in HCCI and the future developments in the same are also discussed in the paper.

Abstract

India is the agricultural dominated country. Food problem arises in most developing countries mainly due to the inability to preserve food surpluses rather than due to low production. Hence preservation of agricultural food/crop is very essential to avoid the wastage. Solar energy is abundantly available with us but because of frequently cloud, drying of agricultural product is not effective for special crop like grapes, fig, turmeric, etc. In order to preserve and protect food crop from bacterial growth solar dryer is to be designed. Drying is the process in which moisture of the product can be removed without hampering the nutrients. Mostly direct and indirect mode solar dryer is used to drying the agricultural product. Natural and forced convection solar dryers are used for so many agricultural products. There is tremendous research is going on in solar drying technology to improve the performance of solar dryer. Experimentally it is proved that solar drying technology is economical viable and possible. Thermal energy can be store in solar drying system to improve the performance of solar dryer using different phase change material. In this review paper, we revived direct mode, indirect mode and mixed mode solar dryer for various agricultural crop.

Review on Parametric Study of High Rise Structure with respect to Positioning of Shear Walls

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

Mohammad Sadique Ameen | Prachi P. Bagmare , Dr. N R Dhamge

Abstract

High rise buildings are becoming need of today‘s situation with the population increasing day by day. A trend to high rise building is being seen in the developing cities of India to tackle the housing demand. The buildings become more and more susceptible to the lateral loads because of the wind and earthquake with increased height. Lateral loads can develop high stresses, produce sway movement or even may cause vibration in the structure. Therefore, it is very important for the structure to have sufficient strength against vertical loads together with adequate stiffness to resist lateral loads. Shear walls are among the most common lateral load resisting systems. The usefulness of the shear walls in the structural planning of the multistory buildings has long been recognized. But there are many factors such as placement of shear walls, its thickness, aspect ratio, plan of the building which affects the response of the building towards lateral loads. In the present study an attempt is made to study the effect of the position of shear walls on bending moment, shear force, axial force and torsional force. The detailed investigations are carried out for zone V of Seismic zones of India as per IS 1893 (part 1):2002, considering primary loads (dead, live and seismic loads) and their combinations with appropriate load factor using Staad-Pro.

Review on Steel Beams with Web Openings

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

Rujuta Bhat | L.M.Gupt

Abstract

Modern multi-storey buildings have limitations in floor height because of economic concerns and architectural considerations. Utilities like air ducts, water pipes, etc. require a large space thus compromising the headroom. Steel beams having openings in web are found to be very effective in providing for the loss of this headroom. Lately, the structural designers have been providing such beams to accommodate building services within the construction height as it reduces material volume without affecting strength of the structure or serviceability requirements. According to research, there is a tendency to use building services which require the openings to be upto almost 75% of depth of beams. Rigorous research is carried out on the load carrying capacity of structures having beams with web openings. Experiments have been performed and numerical analyses have been carried out to determine the effectiveness of such beams. This review endeavours to present the research in a collective manner with particular emphasis on behaviour of steel I beams with openings of various shapes under shear and flexure.

Abstract

Self-compacting Concrete (SCC) is special type of concrete that rapidly spread into congested place such as congested reinforcement. Huge sections of concrete can be easily placed using SCC. Problems such as noise pollution on the worksite that is induced by vibration of concrete is drastically reduced by SCC and the number of workers required at the construction site are reduced. In recent years the usage of SCC raised swiftly. The objective of this paper is to develop SCC mixes with different filling material (calcite) and mineral admixture (fly ash).Slump flow, V-funnel time and L-box blocking ratio are the self compacting properties to be included. Also the mechanical properties such as compressive strength, splitting tensile strength is included.

Miss Mulay Susmita Sunil | Mr.Dr.Gupta Anilkumar

Abstract

Human activities on earth produce considerable quantities of waste, which increases due to rise in population. That is more than 2700 million tons per year, including industrial and agricultural waste from rural and urban societies. Now a day, Brick is one of the most important masonry unit as a building material due to its properties. Many attempts have been made to incorporate wastes into the production of bricks. In this paper we experimentally describe the recycling of the waste products like STP Sludge by incorporating it into bricks. It is a practical solution for problems like cost expenditure on waste management and its effect on environment. The STP sludge and Fly ash is extremely close to brick clay in chemical com-position The sewage treatment process generates a sludge that must be dis-posed-off in an environmentally sound manner. The sludge generated in most of the treatment systems around the world is dis-charged into the nearest watercourse. Among all disposal options, the use of sludge in producing constructional elements is considered to be the most economic and environmentally sound option. This paper reviews the recycle of sewage treatment plant sludge and Fly ash against fired clay bricks. Bricks so formed have adequate crushing strength, hardness and water absorption. So, it could be a potential substitute for clay bricks.

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.

Abstract

6-Sigma is a quality tool that measures how far a given process deviates from the perfection. It is considered as the one of the most efficient quality tool so far on the globe, which produces the product with approximately zero defects. Sigma level determines the quality performance of a product, service delivery or a process and provides an overall framework for continuous improvement in the process of an organization. The sigma level can be calculated using the DPMO (Defects Per Million Opportunities) which is a measure of the number of defects occurring in a process. This paper deals with the application of the 6-Sigma methodology in determining the performance level of various failures that occurred in the Load Hauling Dumpers used in open cast mines. DPMO, RPN can fairly determine the machine behaviour. This paper throws some light on establishing the relation between the 6-sigma quality and risk priority number so as to estimate the behaviour of the equipment.

Abstract

Rapid growth of population, consumption of natural resources are making this planet a hot mass. If the same rate of industrial growth is continued, then within few years, all the natural resources will be exhausted. The greed of human kind, converting natural resources into artificial products without considering the effects on the human life has changed the eco-system balance. The wealth is increasing but health is getting worse just because of unplanned natural resources exploitation. The industrial wastes were also causing damage to local eco-systems and resulting into global warming. The rise of sea water levels, melting polar ice caps, reduction of rainfalls, increase in number of cyclones, exhaustion of wildlife is all due to rapid industrialization and unplanned waste management. Efforts are taken to present the safe and sustainable industrialization methods, policies for benefitting industries and environment. Adoption of sustainable industrialization will help to attain global sustainable development objectives..

Abstract

The structure in high seismic areas may be susceptible to the severe damage. Along with gravity load structure has to withstand to lateral load which can develop high stresses. Now a day, shear wall (SW) and infill wall (IW) in R.C.(Reinforce concrete) structure are most popular system to resist lateral load due to earthquake, wind, blast etc. Shear wall are used for lateral load resisting in high rise building Shear wall has high in plane stiffness and strength which can be used to simultaneously resist large horizontal loads and support gravity loads. Masonry infill wall are normally considered as non-structural element and there stiffness contribution are generally ignored in practice, such approach can lead to an unsafe design. Infill behaves like compression strut between column and beam and compression force are transferred from one node to another. In this study, G+7 storey RC structure is modelled as bare frame, shear wall and infilled frame with their different arrangements. Response spectrum and time history method are used for analysis in SAP2000 software and structure was assumed to be situated in zone II. The infill walls were modelled as equivalent diagonal strut. Following parameter are determining like base shear and storey drift.

Seismic Behavior of Horizontally Irregular RC Buildings

Kartik Suresh Mahajan | Dr. K. Gopi Krishna

Abstract

Seismic events viz., Earthquakes are one of the most devastative events faced by mankind which has a potential to cripple even the economy of a nation. Reinforced concrete multi-storied high rise structures have become a common sight in urban habitat. These structures are made irregular in order to provide certain functionalities viz., parking spaces, lighting, ventilation and other architectural considerations in geometry of the structure etc. These irregularities are broadly classified as vertical and horizontal. They cause sudden change in stiffness, strength, mass characteristics of structures, resulting in drastic change in its behavior during earthquakes [10]. It has been established during earlier events at Latur (Maharashtra), Indonesia, Nepal etc., that these types of irregular structures are vulnerable during earthquakes. Hence lot of research is focused in this direction to mitigate the casualties arising due to irregular RC structures. The present paper focuses to study the seismic behavior of RC buildings which have horizontal irregularity (L-, T-, plus- and I-shaped plan configuration) with/without infill walls in comparison to a regular building for various seismic zones in INDIA having soil types I & III. Dynamic analysis using response spectrum from IS 1893 (Part 1):2002 has been performed for regular and irregular buildings using SAP2000. Further, the influence of infill wall, known for its pronounced vulnerability during past earthquakes on the seismic behavior of RC structures is also presented.

N.W.Mankar | Prof. Dr.A.M.Pande

Abstract

In the event of an earthquake, people can be evacuated safely before the building collapses. Major causalities in the earthquakes around the world are due to the structural collapses, majorly structural collapse are due to irregularities in the buildings and due to the architectural complexities, In the present work, it is focused to study the seismic behavior of reinforced concrete structures with plan irregularities, as re-entrant corners for G+5, G+10 & G+15 storied buildings by considering T Shape buildings as a complete building. This study summarizes the effect of Seismic forces on column at re-entrant corners of the building. The building is analyzed as a complete building and separated in it three parts. There is a need to design such a column around 200% to 400% increase in torsion as per case.

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

Dilshad Akthar | Sanjay B Borghate,R.K. Ingle

Abstract

hear wall systems are commonly used lateralload resisting systems in buildings. Implementing Shear walls to resist the lateral forces produced during earthquake requires knowledge of its behaviour and its effect on the total building response. Shear walls can be constructed either using reinforced concrete (RC), steel plates or combination of concrete and steel plates called as composite material. Behaviour of these types of shear walls are different and hence the overall behaviour of the same building with different shear walls will be different. This paper presents a comparative study on building responses of a six storey RC bare frame building with RC shear wall, with steel plate shear wall(SPSW) and with composite steel plate shear wal(CSPW) for gravity and seismic forces. A better understanding on the influence of shear wall material on the building behaviour can be helpful in new constructions and retrofitting of existing buildings.

Abstract

Analysis of reinforced concrete structure is very essential in civil engineering structures. As the advancement in various fields, various software and advance technique are used in analysis and design of RCC buildings. The aim of structural design is to design a structure so that it suffices its intended purpose during its intended lifetime with adequate safety (in terms of strength, stability and structural integrity) and economy. For the analysis of structure various load cases are considered. Such as dead load, live load, earthquake load, wind load. The analysis results depend on the load combinations. In olden age, most of the structure are analysed for gravity loads such as dead load and live load and designed based on the results obtained. Since last decades India is subjected to many earthquake shocks varies for small to moderates. To check the effect of change in soil type and the zone, the seismic analysis is carried out. Analysis results are presented in this paper which shows the variation in lateral forces on structure is depending on the zone & soil type

Seismic Performance Assessment of Fire Affected Reinforced Concrete Building Using Non-Linear Static Procedure

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

Chiranjivee Hadole | Ratnesh Kumar, Onkar G. Kumbhar

Abstract

The occurrence of fire inside a building is an unexpected phenomenon and can break out at any time due to various reasons. Conflagrations following the 1906 San Francisco and 1923 Tokyo earthquakes lead to serious discussions among engineers about simultaneous safety of buildings against earthquake and fire. The correlative study of fire and earthquake can be done in two ways viz. structure subjected to fire following earthquake (post-earthquake fire) and fire affected structure subjected to an earthquake (Pre-earthquake fire). The present study focuses on seismic behaviour of building subjected to pre-earthquake fire. Often, buildings which are subjected to fire are made usable by performing non-structural and cosmetic repairs without proper seismic evaluation and retrofitting. In reality, the fire leads to material strength deterioration; however, the extent of reduction in strength depends on exposure time and temperature. Moreover, the reduction in overall strength of building is uncertain and therefore, the assessment of seismic performance of such fire affected structure becomes important. In this paper results of an analytical study on a five storey RC public building subjected to one hour standard fire is presented. The propagation of fire is considered in vertical direction (i.e. upward as well as downward direction) inside building. Seismic performance assessment of the fire affected models is performed by using non-linear static pushover (NSP) analysis. The lumped plasticity models of fire affected cross-sections are developed for various exposure durations for the standard fire as per Euro code (EC-2). Capacity curve results obtained from NSP shows that fire in bottom storey is more critical and capacity of structure reduces drastically with increase in exposure time. If building does not collapse during fire event, its post fire seismic performance assessment shall be made mandatory.

Seismic Performance Assessment of Pre-Stressed Precast RC Structure Using Non-Linear Static Procedure

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

Vishal Deoda | Ratnesh Kumar, Onkar Kumbhar

Abstract

The prefabricated pre-stressed reinforced concrete structures are becoming popular in various parts of the globe due to its good quality control and less erection time as compared to cast in-situ RC structure. However, in Indian construction industry use of such building systems is not gaining impetus due to hesitation of structural designers concerning its seismic safety. Although, some past analytical and experimental study conducted elsewhere indicates that the pre-stressed precast reinforced concrete (PPRC) structures can perform well under seismic loading. The improvement in seismic performance was observed due to the use of pre-stress post tensioned tendons connecting beam-column interface. In case of PPRC structure, the joints are not monolithic and hence the overall force distribution in the beam-column framing system will be different than that of monolithic reinforced concrete (MRC) frame structure. Therefore, the present work proposes a new iterative process of linear analysis to determine the internal elemental forces viz. bending moment, shear force and axial load for PPRC structure. Pre-stressed precast beams and non-pre-stressed cast-in-situ columns have been considered for 3D modelling of the building. The nonlinear moment-rotation properties for beam-column interface are obtained from monolithic beam analogy. The comparative study of linear analysis results and non-linear seismic performance of MRC structure as well as PPRC structure has been performed

Seismic Performance of Asymmetrical Building with TMD

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

T. Naga Sai | P. Kamatchi, A.S.Santhi

Abstract

The Eccentricity in center of mass and the center of rigidity under the application of lateral loads causes different behaviour in flexible edge and stiff edge of an asymmetrical building when compared to the behaviour in edges of a symmetrical building. In this study, a typical ten storey RCC building with rectangular plan is considered with eccentricities introduced along the X-direction. Four different earthquakes are considered for linear time history analysis in Y-direction of the building. A tuned mass damper (TMD) with optimum tuning frequency and optimum damping ratio has been chosen with mass ratio 0.05 to control the edge displacements and base shear due to the application of earthquake time histories. The flexible and stiff edge response ratios in terms of peak displacements and normalized base shear with and without TMD are studied with respect to eccentricity ratio and frequency ratio of the building. The response ratios of flexible edge is higher than the response ratio of stiff edge with respect to both eccentricity ratio and frequency ratio for all four earthquakes considered. This study brings out the importance of including the effect of asymmetry in the design of TMD.

Rohit Ravva | Suhasini Madhekar

Abstract

Pounding refers to collision of structures which occurs during earthquake when structures have different dynamic characteristics. In dense urban areas, the potential for closely spaced buildings to pound against each other exists. Pounding has also been observed between bridge components. The present work is focused on building pounding. Pounding has caused severe damage and even instant collapses in past earthquakes. Pounding forces are not accounted for in conventional design process and these can be several times greater than the seismic action effects anticipated by building codes. In the present work, the pounding phenomenon has been thoroughly studied. The factors affecting pounding such as separation distance, characteristics of earthquake ground motion, type of pounding namely, slab to slab pounding and mid column pounding have been investigated. The 12 storey and 8 storey buildings having symmetrical plan dimensions have been considered for pounding study. For analysis, the finite element software SAP2000 has been used and for impact force simulation the linear spring gap element is used. It was observed that, the member forces increased due to pounding. The axial force and bending moment were marginally on higher side in case of mid column pounding. However, the shear force was tremendously increased due to mid column pounding effect. The pounding forces in case of mid column pounding were observed to be less than the slab to slab pounding forces.

Abstract

Earthquakes are one amongst natures greatest hazards; throughout historic time they have caused significant loss of life and severe damage to property, especially to man-made structures. A large proportion of worlds population lives in regions of seismic hazards. The application of the base isolation techniques to protect structures against damage from earthquake attacks has been considered as one of the most effective approaches and has gained increasing acceptance during the last two decades. Seismic isolation system consists of the installation mechanisms which isolates the structure from the base by providing seismic isolators. The seismic isolation system is mounted beneath the superstructure and is referred as Base Isolation. The main purpose of the base isolation device is to minimize the horizontal acceleration transmitted to the superstructure. Base isolation is very promising technology to protect different structures like building, bridges, airport terminals and nuclear power plants etc. from seismic excitation. This work pertains to the study of a G+8 storeyed hospital building. To compare the seismic effects of fixed base structure with respect to isolated structure, the building was analysed using response spectrum and Time history(El-Centro, having magnitude 6.9)methods. When the fixed frame structure was analyzed, the top storey displacement, base shear, inter storey drifts and end moments were found to be beyond the limits of IS1983-2002. Inorder to reduce them, LRB(Lead Rubber Bearing) base isolators were installed at the base of the building. The report also includes the comparative study of the building with and without isolators.

L.N. Pattanaik  | Abinash Jena

Abstract

In present time, the market fluctuates in terms of demand and variety of the products produced from a manufacturing industry and that have been increased a lot due to the emerging competition in the global market. Therefore, the prime need for the manufacturing industry is developing the capability of producing a large variety of products along with maintaining the fluctuating demand as per the requirement of customers. Hence, a new paradigm of assembling system should be implemented in the existing systems of industries to withstand the issues related to varieties and demands. This paradigm is Reconfigurable Assembly Systems (RAS), which can reconfigure assembling systems quickly to change the quantities of products to be assembled along with the variety of products that are to be assembled within a product family. This paper is based on a case study on an industrial assembling system, where a complex multicriteria decision-making problem was structured in order to find an ideal alternative solution based on RAS strategy. Several criteria and feasible alternatives related to RAS strategies were selected with the help of the decision makers from various departments of that Industry. The linguistic ratings of each criterion for the alternatives were collected from the decision makers based on a long-term planning horizon of the industry in the case study. This conflicting multi-criteria decision making (MCDM) problem was solved using TOPSIS method in a fuzzy environment to select the best alternative for the existing assembling system.

Shear Bond Strength of Composite Slab: Comparison of Different Codes and Experimental Data

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

Parshva Shah | A Y Vyavahare

Abstract

In modern construction industry fast and economical construction is an essential requirement. Composite slab, in which profile deck acts as a permanent formwork during construction and as a tensile reinforcement after setting of concrete, satisfies both of these requirements. Still due to lack of particular standard for designing of composite slab, its usage is limited in India. Behavior of composite slab mainly depends on shear bond between profile deck and concrete, but from past research it was found that shear bond is the most critical type of failure in composite slab. So to understand it, various provisions for calculating shear bond strength from the different codes (ANSI/SDI C-2011, EN 1994-1-1 (2004), Hongkong(2011)) have been studied and their results are compared with experimental data taken from the past literature.

Syed Tabin Rushad | Shashikant Duggal

Abstract

U-wrapped externally bonded Glass Fiber Reinforced Polymer (GFRP) provides a valuable alternative for strengthening of shear deficient beams. The effect of GFRP laminates up to three laminas for strengthening the beams in shear has been studied. The GFRP laminate (00/450/450/00) was wrapped in U-fashion on the beams, to ascertain its suitability for strengthening the beams. Beams, U-wrapped with GFRP all along the span, were tested by four-point loading. The results of the experimental program were validated using the software ANSYS. It has been found that considerable enhancement of shear strength can be achieved for shear deficient beams wrapped with GFRP laminates.

Kanak N. Parate | Dr. Ratnesh Kumar

Abstract

Poor performance RC beam-column joints have been recognized as the main cause of failure of many RC framed buildings in the past earthquakes. The techniques to determine the strength of joints have been proposed by many researchers; however, the significant difference observed between the results of experimental and analytical models. The experimental database consisting of 100 exterior joints from the literature have been considered for the parametric analysis. In present study the influence of various significant parameters such as concrete compressive strength, beam longitudinal reinforcement, column axial load, dimensions of interconnecting beam and column, and joint shear reinforcement have been evaluated and an empirical joint shear strength model has been proposed. The model considers the appropriate contribution of various aforementioned parameters. The predictions of proposed joint shear strength model along with the earlier proposed six empirical models have been compared with the experimental database. It has been observed that the prediction of the proposed model is more precise than other previously proposed models. Moreover, the proposed model is comprehensive and simplified, and can be readily used in design offices.

Single- And Multi Level Inverter-Based Renewable Energy Sources For Mitigation of Grid Faults

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

K. Suresh | A. Kishore Kumar,M .Gopi Siva Prasad

Abstract

Grid-connected distributed generation sources interfaced with voltage source inverters (VSIs) need to be disconnected from the grid under: 1) excessive dc-link voltage; 2) excessive ac currents; and 3) loss of grid-voltage synchronization. In this paper, the control of single- and two-stage grid-connected VSIs in photovoltaic (PV) power plants is developed to address the issue of inverter disconnecting under various grid faults. Inverter control incorporates reactive power support in the case of voltage sags based on the grid codes (GCs) requirements to ride-through the faults and support the grid voltages. A case study of a 1-MW system simulated in MATLAB/Simulink software is used to illustrate the proposed control. Problems that may occur during grid faults along with associated remedies are discussed. The results presented illustrate the capability of the system to ride-through different types of grid faults.

Solar Powered Automatic Railway Gate

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

Rajesh Kumar | Santoshkumara, Sharan annangi.,Vinod kumar M, Sridhar chilukuru

Abstract

The present work attempts to automate the opening and closing of gates at a railway level crossing. In general, level crossing gates are operated manually by a gate keeper. The gate keeper receives the information about the train arrival from a near station. When the train starts to leave the station, the station in-charge delivers this information to the closest gatekeeper to get ready. This human intervention can be avoided by automating the process. In situations where the train is late due to some reason, the gates remain closed for long durations causing dense traffic jam near the gates. This too can be prevented by automation. The proposed system uses infrared sensors to detect the arrival and departure of trains at the railway level crossing and Arduino to control the opening/closing of gates. The system uses two IR sensors to detect the arrival of the train and a third IR sensor to detect the departure of the train. When the arrival of the train is sensed, signals are provided to the traffic indicating the arrival of the train on the track. When the second sensor detects the train then the signal turns red and the motor operates to close the gate. The gate remains closed until the train completely moves away from the level cross. When the departure of the train is detected by the third sensor, the traffic signal turns green and the motor operates to open the gate. Thus automation of the gate operations at the railway level cross is achieved using sensor.

Solid waste management has been one of the neglected areas of urban management activities in India, in cities and towns hardly 50 per cent of the solid wastes generated are collected, transported and disposed off, giving rise to insanitary conditions and diseases. Efficient garbage collection, transportation and disposal are among the vital functions of Urban Local Bodies. Despite the fact that a large number of staff is employed by them to discharge this function and a substantial portion of their annual budget is spent only on garbage collection, transportation and disposal, the situation in towns and cities remains far from satisfactory, the issue of recycling of solid waste has not received due attention. With the solid waste generation with time, the importance of recycling needs to be recognized and given due importance. Waste landfills can cause both immediate environmental impacts through geotechnical-related failures as well as long term damage from leakage of unacceptable levels of contamination. Landfill design and operational practices can be used, sometimes in combination with Municipal Solid Waste(MSW) pre-treatment techniques, to control effectively landfill behaviour.

Abstract

For sustainable water management, the role of water pricing is widely recognized in many areas of the world because of the increasing scarcity of water resources and high competition between water users and environmental degradation. The situational analysis of existing water infrastructure in Mandalay was conducted and, major aspects for challenges to industrial water pricing are found out. The questionnaire survey was also performed based on “Statistics Canada, Industrial Water Survey: Manufacturing Industries, 2011” to determine the industrial water demand and cost of water. In this study, industries surveyed for industrial water use in Mandalay industrial zone are six large size factories and three SMEs. Totally nine numbers of factories are surveyed in Mandalay industrial zones. Other four numbers of surveyed factories in this study are under Kyaukse government industrial zone. These four factories are large size industries. Industries are categorized according to standard industrial classification (SIC) code. From the demand side management, price elasticity of water demand for selected industries is evaluated using mid-point formula. The secondary academic sources such as papers, journals and books were studied and adopted to search the possible solutions to challenges of industrial water pricing and they are proposed. As a conclusion, eleven numbers of solutions to challenges of industrial water pricing are proposed from this research.

Abstract

GMAW (Gas Metal Arc Welding) is an arc welding process which is widely used in industry to join the metals. In this present work we have investigated the effect of varying welding parameters on the weld bead quality of Mild Steel flat having 12mm thickness. The chosen input parameters for the study are Welding Voltage, Welding Current and the travel speed of welding torch. The output parameters chosen are Weld Bead Width, Weld Bead Height, Depth of Penetration and Depth of Heat Affected Zone (HAZ). The four levels of experimental set-ups for each of the input parameters are considered and other process parameters are kept constant for the study. Hence the total numbers of experimental set-ups are 64 and the corresponding values of output parameters are found. As this is a Multi-Response Problem, it is being optimized to Single-Response Problem using Weighted Principal Components (WPC) Method. Artificial Neural Networks (sANN), Error Back Propagation Procedure is being used for the prediction of optimal process parameters for GMAW process in this present work. The finite element analysis of residual stresses in butt welding of two similar plates is performed with the ANSYS software

Dattijo, F. M | 

Abstract

Strawbale is generated from dried stalk of wheat, rice, rye or oats straw put together in bales and used for construction or gardening. The construction method is referred to as Strawbale construction or Brown construction. Strawbale can be used as a material for building insulation, structural building element or both. It is a sustainable material as it is being sourced for from agricultural grain waste. This research is aimed at exploring the thermal characteristics, cost efficiency, weight and growth rate of strawbale as a sustainable building construction material. The research was based on literature review and observation of existing buildings made from strawbale as both structural material and building insulation. It was found that strawbale construction can be one of the best alternative building construction technique because it is a renewable resource having high thermal performance, lightweight, cost effectiveness, health value and fire retarding ability. The research found out that strawbale construction can be applied to all kinds of construction if care is taken during placement of the bales. It requires relatively less technical know-how and funding. It also provides a sustainable alternative for which to put grain stalk waste to as against burning which introduces carbon dioxide into the atmosphere. It was found that the cost efficiency of strawbale falls at 48% and its lightweight properties falls at 68% compared to adobe block. The research concludes that strawbale is indeed among the best alternative sustainable building construction material and its construction can be explored and applied in Nigeria as we have the available natural resource in abundance.

Abstract

Civil structures made of steel reinforced concrete normally suffer from corrosion of the steel by the salt, which results in the failure of those structures. Constant repairing and maintenance is needed to enhance the life cycle of those civil structures. There are many ways to minimize the failure of the concrete structures made of steel reinforce concrete. The custom approach is to adhesively bond fiber polymer composites onto the structure. This also helps to increase the toughness and tensile strength and improve the cracking and deformation characteristics of the resultant composite. The main aim of this experiment is to study the strength properties of polypropylene fiber concrete for M20 grade with 0%, 1.5%, 5%, 7.5% and 10% by weight of concrete. Experimental program consisted of compressive strength test, split tensile strength test and flexural strength tests on conventional concrete and polypropylene fiber concrete. Polypropylene Fiber Concrete is an embryonic construction material which can be described as a concrete having high mechanical strength, Stiffness and durability. By utilization of Polypropylene fibers in concrete not only optimum utilization of materials is achieved but also the cost reduction is achieved. The samples with added Polypropylene fibers of 1.5 % showed better results in comparison with the others. The influence of polypropylene fibers has been studied in different proportioning and fiber length to improve the performance characteristics of the lightweight cement composites. Fibers used in length of 12mm by cement weight in the mixture design. Hardened concrete properties such as: 7days, 21 days and 28 days compressive strength, splitting tensile strength, flexural strength, water absorption, and shrinkage were evaluated. Fiber addition was seen to enhance the physical and mechanical properties of lightweight concrete. Hence this hybrid fiber reinforced concrete with industrial waste fibers is doubly advantageous as it provides a superior performance without increasing the cost of the concrete

Studies on Behavior of Bolted Beam-Column Joints

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

Dr. Aravindkumar. B. Harwalkar | Sunil Police Patil

Abstract

The behaviour of joints or connections is very complex due to the various factors which influence them, such as geometric imperfection, lack of fit, residual stresses, connection flexibility, geometric complexity, slipping, and non-linear load deformation characteristics. In bolted joints, a variety of components such as angles cleats, end plates, stiffeners, and bolts are used to transfer and disperse loads from one member to the other. Due to use of bolts continuous load paths are employed to transfer the loads. Connections are often the critical component in a structure, and if they fail, progressive collapse is imminent. Therefore, a test program was aimed at investigating the behavior of a bolted beam-column connection such as unstiffened seated connection, stiffened seated connection, and moment resisting. Non-linear analysis was also performed using ANSYS software to compare the results. The study revealed that stiffened seated connection has got higher load carrying capacity and resilience. The analytical approach by ANSYS method can be adopted using modification factors.

Abstract

Welding is the process of joining two pieces of metal by creating a strong metallurgical bond between them by heating or pressure or both. Welding offers many advantages over bolting and riveting. A test program was carried out to investigate the behavior of welded beam-column joints such as unstiffened seated connection, stiffened seated connection and moment resisting connection under static loading condition. Finite element analysis was performed on beam column joint using ANSYS software and the analyzed results are validated with experimental results. It was observed that load carrying capacity and resilience of seated connection was more than that of other two types of connection. Modified ANSYS results for deflection were in close agreement with experimental results.

Abstract

The heat pipe is a device of very high thermal conductance. The idea of the heat pipe was first suggested by gaugler in 1942 until its independent invention by groover (1960s). The heat pipe is similar in some respects to the thermosyphon. Most commonly used heat pipes for Spacecraft applications use Ammonia as the working fluid and are made up of an Aluminum extrusion with axillary grooved that works as the wick. This study attempts to understand the operation of Ammonia heat pipes with multiple heat sources.

Studies on Pile Subjected To Axial and Lateral Loading

Abstract

Offshore structures, namely, oil drilling platforms, jetties, tension leg platforms etc. are mostly supported on pile foundation. Apart from the usual super structure load (dead load, live load, etc.), these piles are subjected to continuous lateral loading resulting from ocean waves. The combined type of loading induces progressive degradation of the foundation capacity associated with increased pile head displacement. In connection with the above, a total of 18 model pile load tests have been conducted in a model tank filled by sand and clay to examine the behavior of single pile under vertical and lateral loading. Pile is subjected to axial compressive loads and lateral load, for varying type of soil, combinations of loading and L/D ratio. Result indicate that the vertical load capacity of pile increases with L/D ratio and for sand bed compared to clay bed. The effect of L/D ratio and type of soil is less felt on the lateral load capacity of pile unlike vertical load capacity. In the case of vertical and lateral loading combination, at constant vertical load the lateral load carrying capacity of pile is lesser than that of the lateral load carrying capacity of pile without vertical load.

Studies on Raw Material Optimization in Cold Forging By Reverse Extrusion Technique

Abstract

Process improvement is the proactive task of identifying, analysing and improving upon an existing process within an organization for optimization and to meet new quotas of standards and efficiency. The part field housing cup that houses starter solenoid in tractors goes through several processes related to machining and plating. The focus is on bringing down the waste in the cold extrusion process that the part undergoes by restricting free flow of material onto unwanted runoff which is later cut off in CNC machining. Cold extrusion is a push through compressive forming process with the starting material at room temperature. In forward extrusion, the material flows in the same direction as the punch displacement and the material movement cannot be restricted in this process easily, hence a considerable amount of material is wasted as free flow in unwanted areas. The aim is to bring down this waste material by restricting unwanted material flow in cold forging process. In the forging process the material movement was initially in the direction of die and caused runoff of extra material in the direction of punch, which had to be machined out later. Restricting the material movement by minor design changes resulted in bucking of the slug and increases pressure on die and die sleeve. The extra material movement was thus restricted by redesigning the process to reverse forging where the part design was incorporated in the punch thus reducing the need to restrict material movement and also eliminating unwanted runoff. A considerable reduction in cost and reduction in material wastage was brought about in the extrusion process. There has been a 19.35% reduction in the weight of raw material from 465 grams to 375 grams and the production cost of the part was reduced by 16.15% from initial cost of Rs. 29.89 to Rs. 25.02. Several constraints and gaps in the process were addressed such as buckling of the slug, sticking of part to the punch, material waste due to extra stock material and breaking of the sleeve due to pressure of reverse extrusion. Further reforming the designs for reverse extrusion process, the stresses on the tools were also reduced (counter punch and die) which upon failure would bear very high costs. Thus a methodology was devised to restrict material run off into unwanted areas without increasing the stress on die and punch.

Study and Comparison Of AL-SIC Composite With Pure As Cast Aluminium For Wear Behavior

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

Harinderjit Singh | Niraj Bala,Vickramjeet Singh

Abstract

Silicon carbide exists in about 250 crystalline forms [3]. Alpha silicon carbide (?-SiC) is the most commonly encountered polymorph; it is formed at temperatures greater than 1700 C and has a hexagonal crystal structure. The high sublimation temperature of SiC (approximately 2700 C) makes it useful for bearings and furnace parts. Silicon carbide does not melt at any known pressure. Aluminium (Al) alloys are gaining more recognition as a lighter structural material for light weight applications, due to their low density and high stiffness-to-weight ratio. As summarized from the literature Metallic Carbides or Oxides are most commonly used reinforcements in aluminium matrix. Silicon Carbide was used in the current research work as reinforcement for Aluminium matrix, mainly because of its high wear resistance and high hardness applications. Al-SiC Composite was fabricated using cost effective stir casting technique and dry sliding wear testing was performed on a pin on disk type wear testing machine. Optical macrographs and SEM images were taken to study the wear pattern and particle distribution in the cast composite. Results shown that Al-SiC composite material was found to be more wear resistant than pure as cast aluminium with uniform particle distribution. So it can be recommended for wear resistance applications and more experiments can be planned to find out the optimum configuration to be used for fabricating Al-SiC composite materials.

Study of Base Isolation Technique for Design of Earthquake Resistant Structures

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

Prachi Mishra | Priti Shridhar Tagde, Yamini Narendra Deshmukh

Abstract

Conventional seismic design attempts to make buildings that do not collapse under strong earthquake shaking, but may sustain damage to non-structural elements and to some structural members in the building. Non-structural components may consist of furniture, equipment, partitions, curtain wall systems, piping, electrical equipment and many other items. There are mainly three main categories: architectural components, mechanical and electrical equipments, and building contents. This may render the building non-functional after the earthquake, which may be problematic in some structures, like hospitals, which need to remain functional during the earthquake. Non-structural components are sensitive to large floor accelerations, velocities, and displacements. When a building is subjected to an earthquake ground motion, the building induces motion, resulting in floor accelerations higher than the ground acceleration. Hence, it is present need and also a duty of civil engineers to innovate earthquake resisting design approach to reduce such type of structural damages. Special techniques are required to design buildings such that they remain practically undamaged even in a severe earthquake. The idea behind base isolation is to detach (isolate) the building from the ground in such a way that earthquake motions are not transmitted up through the building, or at least greatly reduced.

Abstract

Indias long-standing problems in delay in highway project included lack of funding, weak capability to implement projects, poor policy coordination, and delays in decision making. The government took actions to fill up the financing gap, such as increasing the funds for highway development and facilitating private sector participation. Despite these efforts, fundamental issues still remained including introducing more sophisticated financial instruments, diversifying methods to involve the private sector, and enhancing the financial and managerial autonomy of the National Highways Authority of India (NHAI) for eventual corporatization. During last financial year about 40% of projects totaling 14,000 km and costing around Rs 94,000 crores got delayed, and 70% of these are managed by NHAI and the total cost of these works is close to Rs 80,500 crores. NHAI was implementing 185 projects during 2014-15 costing Rs 1.36 lakh crores. Out of the 185 projects, 120 were delayed. This covered 9,376 km and their total cost was around Rs 80,500 crore. The major role in the delay of project is due to Land Acquisition, which is a major part of concern in our research work. The paper deals with analysis of Western Transport Corridor which was funded by ADB. The Western Transport Corridor, comprising NH-8 and NH-4, connecting Delhi, Mumbai, Bangalore, and Chennai (Golden Quadrilateral) is one of the busiest corridors in India. The section between Bangalore and Mumbai falling within NH-4 also has high traffic volume. At appraisal, the project was envisaged to be implemented over 48 months, inclusive of procurement and pre-construction activities, and was expected to be completed by 30 June 2005 but it was completed on 7 August 2012.

Abstract

Wood is an important natural material and being used for various applications since ages. The larger percentage of the timber wood is used for furniture making as well as a construction material in addition to being used as an engineering material. The wood as an engineering material possess anisotropic properties and some time has random defects. During manual wood machining operations one can take care of anisotropic nature of wood properties as well as the random defects but it is obtained at the cost of a lot of time. The CNC machining of wood can help us save a lot of machining time while simultaneously offer better machining accuracy, but it is desired that the relationship of machining parameters to be selected and the desired machined properties of the wood samples be studied to explore the full potential of using CNC wood machining systems. The wood as an engineering material has several mechanical properties but those mechanical properties which directly influence the machinability of wood are required to be studied. In this present work the previously published literature has been studied in detail to identify the mechanical properties of wood which affect the machinability of wood. Further a systematic approach has been used to determine the values of these mechanical properties as per standard procedure available from the Bureau of Indian Standards as well as standard published standard procedures. The six Indian wood species are used in the present study and an effort is made to establish a correlation between the mechanical properties of these wood species with the cutting forces observed in slot milling and the surface finish obtained in the bottom of the slotted cut. It has been observed that the wood grain orientation is a key factor for machinability of wood because different slot milling orientation gives different measurable output of surface finish and cutting forces. Procedures to find out different mechanical properties are discussed and their averaged values are considered for analysis. A high rpm 3-axis vertical CNC router is used in the present study for slot and plunge milling while a force dynamometer is used for recording the magnitude of cutting forces thus produced. A stylus type surface roughness tester was then used to measure surface roughness of various machined samples. The results of different mechanical properties, various cutting forces and surface finish are thus analysed to identify the relationship among them.

Abstract

Analysis of structural performance of a building plays a vital role in its efficient design and resistance to withstand earthquakes. Weight of a building is a major factor in its performance against seismic loading. The seismic load assessment is a very important factor in the performance of the building under the action of earthquakes of different magnitudes and according to these loads; the buildings are designed [4]. One of the main criteria of a structurally sound building is that, it should meet all the functional requirement of the user, for all given parameters, in other words it should be efficient in all respect. The objective of this study is to compare the lateral (seismic) loads subjected to each floors of four G+5 RC framed buildings of storey heights 3.5m, 4.0m, 4.5m and 5m keeping the plan dimension of the buildings same. The buildings are considered to be located in zone V region. The lateral loads are calculated by vertically distributing the design base shear acting on the buildings using equivalent static load method conforming IS 1893(part 1): 2002. The study results revealed the fact that the lateral load values acting on a particular floor level does not necessarily increase with the increase in height of the buildings especially when the difference in heights are not significant.

Abstract

Cellular Light weight Concrete (CLWC) is not a new invention in concrete world. It has been known since ancient times. It was made using natural aggregates of volcanic origin such as pumice, scoria, etc. The Greeks and the Romans used pumice in building construction.Lightweight concrete can be defined as a type of concrete which includes an expanding agent in that it increases the volume of the mixture while giving additional qualities such as availability and lessened the dead weight. Lightweight concrete maintains its large voids and not forming laitance layers or cement films when placed on the wall. However, sufficient water cement ratio is vital to produce adequate cohesion between cement and water. Insufficient water can cause lack of cohesion between particles, thus loss in strength of concrete. Likewise too much water can cause cement to run off aggregate to form laitance layers, subsequently weakens in strength.This mini project is prepared to show the activities and progress of the lightweight concrete. The performance of lightweight concrete such as compressive strength tests, water absorption and density and supplementary tests and comparisons made with other types of lightweight concrete were carried out.

Study on Dynamic P Delta Effects of a Building with Soft Storey

Abstract

: In modern multi-storey buildings stiffness irregularities are usually found within the building which may be due to the occupancy and architectural appearance. Such irregularities in elevation can lead to buildings with soft stories. Soft story refers to the existence of a building floor that presents a significantly lower stiffness than the others. As per IS1893 (part 1) – 2002, in a soft storey lateral stiffness of the storey is less than 70% of the above storey or less than 80% of the average lateral stiffness of the above three stories. Usually open soft storey is provided at ground level to accommodate parking, reception lobbies etc. also, the soft storey may be constructed at the intermediate level for the purpose such as offices, function halls, supermarkets etc. Such soft storey configuration may lead to serious earthquake damage. To experience minimum damage and less psychological fear in the minds of people during the earthquake, IS1893 (part1):2002, permits maximum inter-storey drift as 0.004 times the storey height. Inter storey drift always depends upon the stiffness of the respective storey. To understand the behavior of p delta effects different types of 20 storey building is modeled using ETABS software and subjected to earthquake loading. Building parameters are varied by introducing shear wall, exterior walls, bracing system and further parameters such as inter-storey drift, roof displacement and column moments are computed and variations in these parameters are discussed and it is observed that building with open soft storey has the least capacity to resist failure during earthquake.

Abstract

Cracks in concrete are unavoidable and it is one of the inherent weaknesses of concrete. Sometimes water and other salts seep through these cracks because of which corrosion initiates, and thus reduce the life of concrete. So there was a need to develop a self-repairing material which can remediate the cracks and fissures in concrete and bacterial concrete is one of them. In this research, M40 grade of concrete is prepared by adding various amount of bacteria (Bacillus subtilis) to improve strength and durability properties.The bacterial concrete specimens and conventional concrete specimens were immersed in 5% H2So4for 28 days and it was found that bacterial concrete shows better performance comparatively.

Study on the Combined Effect of Corrosive Environment and Impact Loading on the Behaviour of Low Carbon Steel

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

Basukumar H K | Arun K V

Abstract

Investigations were carried out to study the corrosion behaviour, stress corrosion cracking (SCC) and hydrogen embrittlement (HE) of low carbon steels in acidic media by weight loss measurement and Impact test to fracture respectively. The effect on corrosion behavior of metal with different concentration of acidic media was monitored for a specified immersion period. The mechanism of stress-corrosion cracking and hydrogen embrittlement in low carbon steels was investigated using notched specimens, under high velocity loading conditions leading sudden fracture. It was observed that nitric acid environment was most corrosive to steels because of its oxidizing nature on the other hand the ammonium thiocynate environment showed hydrogen embrittlement of the material. From the experimental results, it can be observed that material experiences the ductile-to-brittle transition with increasing in soaking period. On analysis, at room temperature, HNO3 was found to be more aggressive towards mild steel compare to ammonium thiocynate. Few studies have been carried out to determine the influence of hydrogen on structural steel and its mechanical characteristics, in turn mechanism of hydrogen embrittlement. The result of impact test shows a decreasing trend indicating of reduction of material toughness. The material exhibit brittle failure in NH4SCN treated specimen than the HNO3 treated specimen. The surface analysis also carried out with the help of Scanning electron microscope (SEM). Overall the result suggests that corrosion was observed significantly HNO3 medium. These deductions are due to higher carbon content in medium carbon steel coupled with various aggressive corrosion constituents contained in these media. Hydrogen embrittlement, as well as carbon cracking, is responsible for SCC of these materials in the acidic media.

Study on the Progressive Collapse Behaviour of Steel and RCC Moment Resisting Frames

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

Rithika Nanaiya | Imtiyaz A Parvez,Kiran Kamath

Abstract

One of the key requirements for any major construction is the structural safety of the building along with the ability to resist partial or total collapse. One or more structural elements fail due to abnormal loading leading to the collapse of the entire structure progressively. This phenomenon is referred to as Progressive Collapse. Seismic loading may also cause progressive collapse of the structure due to repeated lateral loading on a critical load bearing element in a building in seismically prone regions. The capacity of a building has been analysed to resist collapse of a 15 storey 3D Steel and RCC moment resisting frames. They have been modelled and designed for seismic zone 5 as per Indian Standards using ETABS. Three scenarios of column removal namely middle, corner and interior has been studied by the linear method of analysis to arrive at the most critical location of column loss. The Demand Capacity Ratio (DCR) has been assessed in the critical regions as per the provisions of GSA guidelines. Further, the variation in the maximum vertical displacement values for both the steel and RCC structures has been compared. The study concludes that the loss of column in the corner location proved more susceptible to collapse by comparing the DCR values. It has also been observed that a steel building has the ability to resist collapse following the loss of a column when compared to an RCC building.

Mohammedrafi H. Kerur | T. Nagaraju, M. Ravi Prakash

Abstract

The present theoretical study predicts the static and dynamic performance characteristics of porous journal bearing considering rise in fluid film temperature. The modified Reynolds equation governing the pressure field within fluid-film is derived by simplifying the Navier-Stokes equation. The modified energy equations governing the temperature fields are also derived for both fluid film and porous medium. The modified Reynolds and energy equations are simultaneously solved using finite element method with appropriate iterative schemes. The influence of permeability of porous matrix on static and dynamic performance characteristics of porous journal bearing is computed using thermo-hydrodynamic (THD) analysis and compared with the isothermal performance characteristics of the same bearing. The performance parameters of finite porous journal bearings under THD analysis were found to be significantly influenced by the permeability of porous matrix. The influence of permeability of porous matrix has observed to couple with operating eccentricity, speed of journal and temperature effects.

D Srinivas Rao | A Krishnaiah ,Y Krishna,Syed Adil

Abstract

Ferro-Aluminium Mechanical Alloy (Fe-Al MA) is emerging as a popular choice in material selection for critical applications, owing to its favorable versatile attributes. But the metal in bulk form suffers from poor machinability resulting in expensive machining and lesser productivity. In the current work, this drawback is addressed through a sustainable solution obtained from a series of machining experiments to recognize the best suitable cutting parameters using PCBN tool inserts. It recommends that machining of Fe-Al specimen at optimum cutting parameters enhances tool-life significantly and marginally improves productivity and machining economy. Experimental validation of the process outcomes is further carried out to confirm the genuineness of the approach.

Abstract

This paper emphasis on the precipitation initiated flooding which is produced by excessive depth rainfall within the city area that is overwhelmed due to improper management of drainage system. Globally water logging is a concern in all developed countries and is playing a vital role in the infrastructure management. It has become part and parcel of mostly all around the world and the good team of researchers and engineers are working to solve this issue but the recurrence of this issue is increasing. This paper speaks about the blue roof network system which has the potential to reduce the peak runoff of storm water and this study examines its potential for controlling drainage overflows through a GIS analysis in H-East ward of Mumbai, India which has been encountering water logging problem from last few decades. The Mumbai's drainage system works on the gravity based system and the end outfall is placed below as well as above the mean sea level based on various criteria such as tidal levels etc. During heavy rains, the high tides create a problem in the drainage system in such a way that the rainwater remains in the sewer and can't be drained out in the streams and this create water logging issues in the nearby vicinity. Flood management measures and study is needed at this point of time and because always space is a constraint in a city like Mumbai, the proposed measures have to be progressive to obtain the desired protection degree with minimal disturbance to the existing conditions. This study finds a solution to this problem by capturing of as much precipitation as possible every time it rains. Through a comprehensive design of control flow device over the conventional drain on the roof terrace of buildings also the study demonstrate herein with a concept of blue roofs network system on every building in the study area would decrease the number of sewer overflow events.

Abstract

Algae’s are the ancient ancestors of all aquatic plants. These algae’s are mainly classified into micro and macro algae groups and these groups combiningly have more than 2,00,000 species. 60-70% of the present day fossil fuel i.e., petroleum is contributed by algae’s. Today’s Fossil fuel energy resources are depleting rapidly and most importantly the liquid fossil fuel will be diminished by the middle of this century. In addition, the fossil fuel is directly related to air pollution, land and water degradation. In these circumstances, biofuels from renewable sources can be an alternative to reduce our dependency on fossil fuel and assist to maintain the healthy global environment and economic sustainability. Production of biofuels from food stock generally consumed by humans or animals can be problematic and the root cause of worldwide dissatisfaction. Biofuels production from microalgae can provide some distinctive advantages such as their rapid growth rate, greenhouse gas fixation ability and high production capacity of lipids. In this regard in the present work we developed a micro algae photo-bioreactor which suits for the operating conditions and cultivation conditions of micro algae to get maximum yields of biofuels in less cost and it can be utilized for both domestic and commercial purposes.

Abstract

A structure malleable to the altering environmental conditions can be termed as a Smart Structure. Smart structures sense the changes in the structure when they are subjected to extreme conditions like vibrations. Smart structures sense and inform the user about the damages in the structure. They alter the material characteristics and properties to sustain or to prevent the damaging effects on the structure. They also optimize the performance of the structure under critical conditions. Some of the factors disturbing structural health are Differential Settlement, Earthquakes & Vibrations, Structural Distress and Corrosion of Reinforcement. This paper discusses these factors and smart or intelligent ways to prevent it. The smartness of the structure can be achieved by smart materials resulting from molecular modification to variable energy conditions. Smart materials Shape-Memory Alloys (SMA), Magneto- Rheological Fluids, Non-Corrodible Materials, etc. are used to deal the factors affecting structural health.

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

Abstract

Biodiesel can be produced from vegetable oils and also from waste fats. Biodiesel is a mono-alkyl-ester of long chain fatty acids derived from renewable feedstock such as vegetable oils by transesterification process. The esterified cotton seed oil, pungam oil, rice bran oil, and tamanu oil are chosen as the alternative fuels. Among these oils, tamanu oil is considered for the first time as an alternative fuel. An experiment is conducted to obtain the operating characteristics of the computerized variable compression ratio (VCR) multifuel research engine run by chosen esterified oils, and the results are compared with esterified tamanu oil. From the comparison of results, it is inferred that the engine performance is improved with significant reduction in emissions for the chosen oils without any engine modification. The effective compression ratio can be fixed based on the experimental results obtained in the engine since the findings of the present research work infer that the biodiesel obtained from tamanu oil is a promising alternative fuel for direct-injection four-stroke computerized VCR multifuel research engine.

Dr. H. Raghavendra Rao | Mr. A. Vamsi Krishna, Dr. Y. Hari Prasada Reddy

Abstract

The chemical, impact, tensile properties of Bamboo/Grass/Onion fibres reinforced polyester hybrid composites were studied. The effect of alkali treatment for Bamboo/Grass/Onion fibres on these properties was also studied. It was absorbed that tensile properties of hybrid composites increase with bamboo fibre content. These properties found to be higher when alkaline treated bamboo fibres were used in the hybrid composites. The elimination of amorphous hemi – cellulose with alkali treated leading to higher crystallinity of the bamboo fibres with alkali treatment may be responsible for these observations. The effect of alkali treatment on the bonding between Bamboo/Grass/Onion fibres was also studied. The chemical resistance of Bamboo/Grass/Onion reinforced polyester composites to acetic acid, nitric acid, hydrochloric acid, sodium hydroxide, sodium carbonate, benzene, toluene, carbon tetrachloride and water was studied. The bonding between fibres and matrix was studied by metallographic (Scanning Electron Microscope) analysis

Abstract

This project study discusses the combustor liner metal temperature prediction methodology for aero gas turbine. All modes of heat transfer for thermal analysis is considered. Radiation due to combustion gas, conduction due to presence of low conductivity thermal barrier coating and the liner and convection due to combustion gas and cooling air are estimation. Combustor liner metal temperature is an important input for determining the creep life.The objective of the present study is thermal analysis of combustor liner to estimate the metal temperature distribution for a given cooling configuration. Heat loads coming on the liner is calculated to carry out Finite Element analysis using commercial software ANSYS. The geometrical model is generated and meshing is done with suitable elements for thermal analysis. The analysis is carried out for different design steady state conditions to evaluate the maximum metal temperature. 1D analysis is carried for the convective and radiative fluxes from energy balance and 1D metal temperature is estimated. Parametric analysis is carried out to study the effect liner metal temperature with different aerodynamic and geometric parameters like gas temperature, thermal barrier coating thickness, coating conductivity, and combustion gas pressure. It was observed that with increase of thermal barrier coating thickness the liner metal temperature was decreased as the conductive flux was reduced. Emissivity of gas increased with the increase of gas pressure, gas temperature and increase of air/fuel ratio. Increase of gas emissivity increases the liner metal temperature.

Akash Hiremath | M.Ravitej, DR. H Manjunath

Abstract

To increase thermal efficiency, advanced gas turbine is designed to operate at increasingly higher temperature. Since the gas temperature exceed the allowable material temperature, cooling techniques of turbine components are increasingly important. Film cooling is a standard method applied to turbine blades and vanes, whereby cold air is injected from small holes which forms a thin layer over walls and protects the wall from high temperature gases. This study describes thermal analysis of film cooled High Pressure Turbine (HPT) blade platform for an Aero Gas Turbine engine using FEM analysis; platform is exposed to combustor exit gas temperature of 1700K and the coolant air at 800K temperature. During this work the coefficient of discharge (Cd) and film effectiveness (ɛ) of film cooling holes is estimated from CFD analysis. Film cooling adiabatic effectiveness estimation is done using Fluent commercial code, Version 14.5. For the Flat plate film cooling model three different RANS turbulence models are studied I. Realizable k-ɛ turbulence model with enhanced wall treatment. II. Standard k-ω turbulence model. III. SST K-ω turbulence model. With the cooling hole inclined at Ɵ the study is performed at density ratio 1.6 with the mainstream and coolant temperatures at298k and 188K respectively and for two different blowing ratios 0.5 and 1. Centreline adiabatic effectiveness and spanwise adiabatic effectiveness is extracted from the different models and compared with the experimental results. The predicted effectiveness and experimental data are in good agreement. The CFD prediction over predicts the effectiveness. Good quality hexa-mesh is created using ICEM CFD multi-blocking method.

Abstract

Power amplifier is a device which amplifies the signal of communicating device. Thermal analysis was done on the key Componentsof the power amplifier in orderto dissipate maximum heat from the device. The heat input was given to keyComponents i.e. MR (TRANSISTOR) PA COMPONENT of the amplifier ,located on the PCB with a capacity around 195W .Remaining amount of heat distribution was on other components and analysis was done to measure the maximum temperature ofthe components through SOLID WORKS SOFTWARE ". Three analyses were done in order to achieve optimum operating temperature of maximum heat dissipatingcomponents. First, each part of the power amplifier device was modeled and then assembled. After the assembly, thermal analysis was done on the device with 25 fins. Themaximumtemperature of heat dissipating component was around 225 Degree Celsius much higher than the operating junction temperature of the component which is 150 Degree Celsius;hence this design was not acceptable. During second analysis, in order to minimize the temperature of maximum heat dissipating device less than the operating junction temperature number offins were increased from 25 to 30 .Analysis done with this modification gave the resulting temperatures as165.417Degree Celsius. During third analysis, in which the number of the fins remained samebuta cutout given to the PCB and device mounted on inner surface of the housing. As a result the thermal resistance(K/ L) reduced which allowed more heat dissipation and resulted in minimizing the temperature under the given operating conditions.The temperature measured was around 126.7 Degree Celsius. Hence, design was acceptable. This helps the device to runefficiently for definite time period.

Abstract

Conventional energy sources are exhausted day by day. Hence the time has come to switch over this problem and produce environment friendly renewable energy sources. Sun is abundantly available with us. There are n numbers of application of solar energy like solar water heating, solar drying, solar distillation, solar pond, wind mill etc. But limitation of solar energy is, it is only available in day time. Hence efficiency of solar application is low. In order to improve the efficiency of solar application thermal energy storage is a best method. In solar water heating application thermal energy storage is very effective. In solar water heating thermal energy storage can be done by using PCM like paraffin wax and sodium thiosulphate. Paraffin wax absorbs heat energy from solar water heater during day time in the form of latent heat and dissipates this energy when sun rays are not available. This energy storage fulfills the gap between the energy source, the sun, and the application. So the thermal energy storage is essential in the solar water heating system.

Tribology of aluminium metal matrix composite under lubricated sliding: A Review

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

Harpreet Singh, Hiralal Bhowmick | ParamPreet Singh

Abstract

From the past and till the present scenario, the progress over aluminium metal matrix composites (AMMC) is primarily on the fabrication and mechanical characterization of the composites. The reason for focusing on aluminium composite because of their improved mechanical properties, low density, better corrosion resistance and low production cost are very much suitable for various applications in the field of automotive, aerospace and marine industries. The potential tribological behaviors of these composites are also mainly evaluated through dry sliding friction and wear testing. However, in this paper, in addition to the review of dry sliding applications, an attempt has been made to provide an extensive literature review on the effect of oil and oil additives on the sliding wear and friction behavior of aluminium composite. Due to the ever challenging demand for the minimization of wear and coefficient of friction for the AMMCsteel contact, wet tribology is being used. The authors, along with the sufficient evidences from their own works, show the influence of particle based additives over the conventional wet tribology which implies that the particle additives in oil can significantly enhance the tribological performance if suitably formulated, rather than just going for the base oil and other conventional additives.

Abstract

In this project The condition of a driven shaft spinning faster than its driveshaft exists in most bicycles when the rider holds his or her feet still, no longer pushing the pedals. In a fixed-gear bicycle, without a freewheel, the rear wheel would drive the pedals around. An analogous condition exists in an automobile with a manual transmission going down hill or any situation where the driver takes his or her foot off the gas pedal, closing the throttle; the wheels want to drive the engine, possibly at a higher RPM.

Under Slung Steel Truss Bridge with Composite RCC Deck Bridge

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

A.Sharma | P.K.Singh, K.K.Pathak

Abstract

The most common cause of structural failure in steel bridges is buckling of a compression member. Buckling failure is a sudden failure and offers no warning before collapse. Recently, in the year 2012, a 190m span steel truss bridge over river Alaknanda, in Uttrakhand, India, suddenly collapsed during casting of the deck slab due to buckling of one of its top cord compression members. Its failure during construction stage raised doubts on current design practices where, the factor of safety provided by the codes do not guarantee performance of the bridge in overload conditions. In the case of composite under slung bridges, premature buckling of top cord compression member is prevented by the RCC deck connected with the steel truss with the help of shear studs. Further, this allows the steel truss members to take stress up to their ultimate strength. A 30 m span bridge is analysed with composite action of RCC deck for service and overload conditions. The maximum flexural strain due to live load alone in the RCC deck slab is found to be 0.00026. Shrinkage strain for M30 concrete deck slab is taken as 0.0003. Hence, even during service condition, composite action between the steel girder and RCC deck slab may not take place. For the analysed deck type bridge, total load on the bridge in terms of uniformly distributed load in service conditions for (DL+LL) case is 153.7kN/m, and in overload condition for 1.5x(DL+LL) case it is 230.55kN/m. At plastic stage the bridge can carry an equivalent udl of 635.98kN/m. Thus, for the plastic collapse, apart from warning due to excessive deflection, there is a factor of safety of 4.1 in comparison to service load. For prestressed concrete bridges, load combination at ultimate strength for severe condition, as per Cl. 12 of IRC: 18-2000, is prescribed as 1.5G+2SG+2.5Q. Whereas, in case of steel truss bridges, as per IRC: 24-2010 and IRC: 6-2010, load combinations and permissible stresses are given in Table 1, Cl. 202.3 for service condition only. IRC codes haven’t provided any specific provision for ultimate strength of steel truss bridges. Therefore, a parallel clause for ultimate strength of steel truss bridges also may be added, for which composite under slung bridges may be found to be suitable.

Abstract

India is the second largest country in the world with about 1,336,087,445 population as on today. In present scenario, population density in our country reaches approximately 455 per square kilometers and in a way to grow at higher side. As we all know the basic requirement for an individual is food, shelter and water to survive. A civil engineer plays an important role in providing shelter to each and every citizen of India. Presently population growth is a main hurdle for an engineer to come across and space in big cities is one of the big task for civil engineers. With the lack of space engineers find their way in designing the slender, taller structures. With the increase in height of building, the study of wind induced building motion becomes very important. Wind tunnel experiments are the basic source to study these motions for taller buildings. But use of wind tunnel is not feasible every time and it is must to find alternate solutions. I.S. 875 (Part - 3): 1987 describes along wind response by gust factor method by considering the effects of change in terrain category. A new code reaffirmed in 2013 is also available to calculate along and across response of buildings. This paper discusses the method for calculating along wind response with use of Indian standard codes and Artificial Neural Network to save the time and money required in wind tunnel experiments.

Abstract

During the 20th century there has been an increase in the consumption of mineral admixtures by the cement, sand and concrete industries. This rate is expected to increase and the increasing demand for cement, sand and concrete is met by partial cement replacement. Substantial energy and cost saving can result when industrial by-products are used as a partial replacement for the energy intensive Portland cement and manufactured sand for natural sand. The presence of mineral admixtures in concrete is known to impart significant improvements in workability and durability. The use of by-products is an environmental friendly method of disposal of large quantities of materials that would otherwise pollute land, water and air. This paper presents the experimental study to investigate the influence of partial replacement of cement by Fly Ash (FA) & Rise Husk Ash (RHA) and Natural sand with Quarry Sand (QS) on the concrete compressive strength, split tensile strength and flexural strength by better understanding of chemistry of constituents of the concrete mix. The use of by-products is an environmental friendly method of disposal of large quantities of materials that would otherwise pollute land, water and air. This study focuses on utilization of waste Pozzolona products such as Fly Ash (FA) and Rice Husk Ash (RHA) as partial replacement to OPC and natural sand by Quarry Sand (QS) to produce blended concrete with an objective to increase the optimum percentage of replacement of pozzolona to OPC without affecting the concrete properties.

Vibration control of Benchmark building with stacked TMDs

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

Sanat Marathe | Suhasini Madhekar

Abstract

Tuned mass dampers (TMDs) placed in sky scrapers show huge deflections and accelerations as they absorb a lot of the energy from the main structure. The responses of these TMDs need to be controlled with some additional dampers to keep their motion in check. The current paper deals with the numerical study of a similar system in which a TMD (secondary TMD) is used to control another TMD (primary TMD). Primary TMD is also analogous to an important equipment such as a server placed in a building which needs to be controlled. In the present study, the response of a 76-storey Benchmark building is investigated under across-wind loads. Dynamic Time History Analysis of the building is performed in MATLAB 2010a using the wind time history data by state space method. In addition to deflections, drift and acceleration responses have also been taken into consideration. Results show that for an optimum mass of primary TMD (0.33%), the overall response (i.e. peak, Root Mean Square (RMS) and average displacement, acceleration and drift) of the structure is reduced up to 56%. Moreover when secondary TMD is placed, for an optimum mass ratio (2%), the overall response reduction of the structure remains same (i.e. 56 %); whereas the overall response of the primary TMD reduces by 36%. With further increase in the mass of secondary TMD, a trend is observed where overall response of primary TMD goes on decreasing whereas that of the structure increases. Thus, a secondary TMD can be used effectively only up to a mass ratio of 2% of primary TMD. If mass ratio of secondary TMD is kept equal to or below 0.4%, more response reduction for primary structure can be achieved

Waste Foundry Sand as Fine Aggregate in Concrete for Resistance to Sulfuric Acid Attack

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

Mr. Aasif M. Baig | Dr. Valsson Varghese

Abstract

The degradation of concrete sewer pipes by sulfuric acid attack is a problem of global scope, resulting in substantial economic losses each year. Waste Foundry Sand (WFS), offers a range of potential improvement mechanisms, used at various dosages to enhance the resistance of concrete made with Pozzolana Portland Cement to chemical sulfuric acid attack with variations in Concentration. The aim of this study is to observe the concrete resistance towards acid attack. The resistance to sulfuric acid of concrete specimens incorporating the Waste Foundry Sand was measured and compared to that of control specimen for both M20 and M40 grades. From the experimental results it is inferred that partial replacement of Waste foundry sand with Fine aggregate in concrete enhance the compressive strength of concrete specimen immersed for 7, 14 and 28 days in H2SO4 solution having concentration of 10%, 20% and 30% (by volume) with pH Value 1, compared with conventional Concrete. It has been observed that Waste foundry sand offers good resistance to acid effect with lesser loss in workability, particularly in higher grade of concrete as compared to lower grade. The mix with 15% waste foundry sand offered comparatively better solutions insisting the concrete modified with the same can be recommended for making good and acid resisting concrete. This study is very much beneficial since a sulfuric acid resistant concrete has been developed using Waste foundry sand as a substitute material to fine aggregate.

Abstract

the possibilities of thermoelectric systems’ contribution to “green” technologies, specifically for waste heat recovery from automobile exhaust system and industry exhausting flue gases or smoke passing through chimney. Recent research shows that TEG as a waste heat harvesting method is useful. Due to distinct benefits of thermoelectric generators, they have become a promising alternative green technology. Thermoelectric generator direct converts wasteheat energy into electrical power where it is unnecessary to consider the cost of the thermal energy input. The application of this technology can also improve the overall efficiency the of energy conversion systems and reduce pollution. Thermoelectric revolves around modern day thermocouples and their application in power generation. The phenomenon involving an inter conversion of heat and electrical energy is termed as thermoelectric effect. The concept of thermoelectric effect was brought forward by a German scientist Thomas Joham Seebeck in 1821. According to this, a voltage is produced at the junction of two different materials. If a closed path is provided a current will flow in the circuit. This is the direct conversion of temperature difference to electric voltage and vice-versa. Below figure shows the illustration of seebeck effect.With the increase in population the energy consumption has also increased. Human race is in search of new technology for different energy sources to meet the present demand. Thermoelectric generation is one such emerging technology. This technology uses the waste heat carried away in flue gas or smoke passing through chimney, automobiles, exhaust etc. which is let into the environment to extract electric power. The conversion from heat to electric potential is done with the help of a device called TEG.

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.
