Abstract

Increasing the rate of heat dissipation in automotive radiators is in great demand due to the use of more powerful engines in relatively small space. Insufficient rate of heat dissipation can result in overheating of the engine, and that causes corrosion and metal weakening of engine parts. The aim of this project is to design radiator for thermal stability of engine with increasing the rate of heat transfer and decreases the computational cost dramatically and leads the way to obtain hydrodynamic and thermal performance of elliptical and helical tube type radiator by using CFD analysis. By adopting this methodology, the thermal performance of a complete radiator design can be obtained within a reasonable computational time and a CFD model with the proposed methodology can be implemented as a design tool for the radiator design which would lead to more optimized radiator designs. Overall heat transfer is calculated for each design of elliptical & helical tube radiator. Different type of nano fluids Ethanol, Methanol, Al2O3/water2%, Al2O3/water3% and CuO/water and other coolants are taken into consideration while running the analysis. By Varying turbulence model and surface Nusselt number, the contours of temperature and pressure drop were calculated and plotted using software ANSYS. The purpose of this study is to minimize the heat load on the engine and lighten automotive component because of heat generation, and to make automotive radiators more compact while maintaining important level of heat performance The cooling capacity of Wagon-R radiator is computed with the proposed computational model and using different type of nano fluid to analyse thermal performance of both elliptical & helical tube type radiator and finally found that helical tube radiator with ethanol as coolant gives better result as compare to elliptical tube.
