3D printing is also known as Additive manufacturing (AM) process, where 3D objects are created by laying down into successive layer of material. In 1984, Charles Hull developed the technology of 3D printing from digital data and named the technique as Stereo lithography (STL) in 1986. In this project, create the prototype of Limited Lean Suspension System by using Fused Deposition Modeling (FDM) process in which the CAD model is designed in Catia v5 software and converted to STL format. The STL format is uploaded to FDM printer and works according to the G-code generated. This prototype is to study the kinematic parameters, working principle and in future research. By using Leaning application it will improves the vehicle stability, smooth cornering and fuel efficiency

and Srinivaas A., “Astray State-Laminar Forced Convective Heat Transfer of Al2O3 – H2O Nanofluid through 3D-Rectangular Cross- Sectional Duct”, International Journal of Recent Technology and Engineering, vol. 8, no. 2s3, pp. 899-907, 2019.[Abstract]


A Steady state-laminar forced convective heat transfer has been simulated by Computational Fluid Dynamics (CFD) with a Single Phase Model (SPM), Multi Phase model & Diameter effects and also determined the effects of nanoparticles concentration and nanofluid flow rate through 3D rectangular duct under certain boundary condition (constant heat flux). The nanofluid contains Alumina nanoparticles of size 60nm diameter used for MPM which is mixed with base fluid (water) with volume fraction of 0% ≤ ȼ ≤ 5% and Reynolds number (Re) ranges from 250 ≤ Re ≤ 1000. ANSYS 18.0 has been used for simulation. Three cases of analysis have been carried out in which the thermal conductivity (k) and dynamic viscosity (µ) of nanofluids are determined using two sets of theoretical models and one set of experimental k & µ data from literature respectively. The nanoparticles which stay more dispersed in the base fluid due to increase in Reynolds number which improves HTC and also decreases the friction factor accordingly. Particular attention has been paid to the variation of heat transfer characteristics when the modeling approach is switched from SPM to MPM. It is revealed that higher heat transfer rates are observed in MPM. The results shows that the friction factor decreases and Nusselt number (Nu) increases when there is an increase in the flow rate and also increase in the volume concentration of the nanofluid, while the pressure drop increases only slightly. The increase in HTC is one of the most important aims for industry and researchers.

Srinivaas A. and M, S., “Modelling and Simulation of Skid Prediction in a Passenger Car”, International Journal of Recent Technology and Engineering (IJRTE) , vol. 8, no. 2s3, 2019.[Abstract]


The vehicle handling is defined as the responsiveness of a vehicle to the driver input. The driver and vehicle is a closed loop system where the driver observes the direction or position of the vehicle in order to correct his input to achieve the desired motion. It is required for the driver to safely ride the vehicle particularly during cornering, acceleration and braking in order to avoid skidding. The skid occurring in a vehicle is a condition in automobile handling where one or more tyres slip relative to the road and the overall vehicle handling gets affected. Tire slip and related slip angle describe the performance of an individual tire. The cornering behaviour of a vehicle is one of the important modes in handling. In this project, a mathematical model is build using MATLAB-SIMULINK for a passenger car undergoing cornering. The steer angles for various speeds and radius of turns are determined and the results are displayed in the form of graphs. An app is designed using the MATLAB app designer which predicts the type of skid- under steer, over steer or neutral steer while the vehicle is undergoing cornering. This system is then simulated in the real time environment with the help of IPG Carmaker and driving scenario designer app in MATLAB and the corresponding results are noted.

S. Gopalakrishnan and Srinivaas A., “Experimental Investigation of Emission Characteristics of Diesel Gasoline Mixture Containing N-butanol”, International Journal of Engineering and Technology(UAE), vol. 7, no. 1, pp. 137-140, 2018.[Abstract]


Emissions have become an important parameter, playing an extensive role in the selection of engines. To find out the alternatives for petroleum based fuels owing to their continuous depletion and the increase in emission rates, research works are being carried out con-tinuously. The prime objective of this work is to study the effects butanol additive to the diesel-gasoline mixture fuelled to a CI engine. The operation is carried out by mixing butanol with diesel-4% gasoline mixture at different proportions and the mixtures are used to run a single cylinder APEX 240PE kirloskar make engine at constant speed under a series of load conditions. The performance characteris-tics of the fuel mixture used is obtained and the concentration of emissions present in the exhaust has been determined using an Emission Analyzer. The mixture can be used as an alternative fuel in diesel engines, thereby producing reduced emission rates. © 2018 Gopalakrishnan. S, Srinivaas. A.

Srinivaas A. and Vishnu, R., “Performance Analysis and Testing of Aftermarket Filters”, International Journal of Engineering and Technology(UAE), vol. 7, pp. 42-47, 2018.[Abstract]


Aftermarket segment is one of the promising and growing section in automobile industry. The popularity of this section is due to the low cost and high replacement rate. Best filters among many will survive in the market. Different Filter manufacturers develop filters for same purpose but varies in their construction. There are a wide variety of aftermarket performance filters for the same type of OEMs. They vary in their brand name, filter area, filter medium, price, service life and method of install. The presence of increased number of aftermarket performance filters has prompted automotive enthusiasts to replace the OEM filter for the same purpose available in lower cost. The paper discusses about the testing procedures to be done to compare the performances both the brands (OEM and Aftermarket filters). All the experiments were conducted at PSG institute of science & Technology Coimbatore. This study shows how much an aftermarket filter varies from that of OEM. The performance of both OEMs (BOSCH and FLEETGUARD) and Aftermarket filter(UCAP) are evaluated by pressure drop, filter efficiency, media strength, porosity tests.

The performance characteristics of different variants of Anti-Lock Braking System (ABS) in a normal passenger car is investigated. ABS prevent lock-up of wheels and maintains steer ability of the vehicle during braking. Vehicle stopping distance, brake pressure, wheel slip and slide-slip are made using Simulink software and system study was conducted an investigation is done. The variants of ABS taken for the study are 2-channel ABS (front wheels), Cross-ABS (alternate wheels: front left and rear right) and full (four channel) ABS. The Simulink model was interfaced with IPG Carmaker and simulation was performed to include the aerodynamics, tire friction and road friction. The results of the simulation were validated to obtain conclusions on the braking performance for different variants of ABS. © 2018 Authors.

The principle of an indaustrially used emission reduction technique is employed in automotive diesel exhaust to reduce the diesel particulate emission. As the Emission regulation are becoming more stringent legislations have been formulated, due to the hazardous increase in the air quality index in major cities. Initially electrostatic precipitation principle and working was investigated. The High voltage requirement in an Electrostatic precipitator is obtained by designing an appropriate circuit in MATLAB -SIMULINK. Mechanical structural design of the new model after treatment device for the specific diesel exhaust was done. Fluid flow analysis of the ESP model was carried out using ANSYS CFX for optimized fluid with a reduced back pressure. Design reconsideration was done in accordance with fluid flow analysis. Accordingly, a new design is developed by considering diesel particulate filter and catalytic converter design to ESP model.
