Abstract. The radiator is a crucial component of the cooling system in an automobile. Its liquid cooling system can be more precisely controlled and offers greater cooling capacity than air-cooling systems such as those found in motorbikes or small aircrafts. As about 1/3rd of the total heat energy from the fuel is dissipated through the engine cooling system, it is necessary to design a robust and effective cooling system. In this study a basic radiator system has been modelled in SolidWorks and conjugate heat transfer simulations have been carried out in ANSYS Fluent. By using commonly used materials such as aluminum for the radiator and water as a coolant the results of this study may be of relevance to a wider audience and be easily compared with other data. This study focuses on four test cases with variations in coolant inlet temperature, namely 373K and 353K as well as coolant and air flow rates of 4m/s or 0.5m/s for water and 2m/s or 0.2m/s for air respectively. The air inlet temperature was fixed at 300K for all readings and the effectiveness of the radiator was found out in all cases. The use of simulation for testing the efficiency and effectiveness of cooling systems helps reduce costs by testing before investing time and money on physical prototypes and helps to develop better systems faster.
