【 摘 要 】

Radiator is employed to transfer thermal energy from one supply system to different for the aim of continuous heating and cooling. It's created to perform cooling process in automobile industy. It is always a source of heat to its environment, this could be either for the aim of heating this surrounding or for cooling the fluid agent equipped to cool the engine. Automobile radiator main perform is to cool the engine by passing the coolant through cylinder water jackets and fins. Modeling of Aluminium radiator is completed by exploitation solid works 2016 software and CFD analysis is performed on radiator by exploitation solid works flow simulation flow process. CFD analysis is performed on radiator by selecting different fluids i.e. one regular fluid water and three nanofluids like Titanium oxide (TiO2), Copper oxide (CuO) and Aluminum oxide (Al2O3). Boundary conditions is provided as 90°C for inlet temperature of fluid, which can cooled by radiator pipe and fins by mean of convection process on ambient temperature of 25°C. Due to convection temperature of fluid flow inside radiator will decrease, which varies in the temperature of fluid along with Pressure and Velocity. By seeing the results we can conclude that nanofluid provide higher convection i.e. better cooling to engine compared to that of water.
