In Student Formula Japan 2019 for the EV Class category, out of 27 teams, only 2 teams were able to complete the endurance event. Some of them are caused by the inadequate cooling system in the car, which causes the engine in the electric formula car to overheat. Therefore, it is necessary to do further research on formula car radiator especially for Anargya ITS Team. One way is to do a review of the position of the radiator.This final project uses ANSYS FLUENT software to simulate the placement of the radiator on the side pod of the ANARGYA MARK 2.0 electric formula car. Simulation modeling in this research is by simplifying the fin part to become a porous medium. The simulation is divided into two stages, the first is one unit cell fin simulation where the results are used to determine the parameters of the porous medium fin. Second, the complete simulation of the radiator to determine the effect of the angle of the radiator position on the air flow with various positions of 90Ëš, 60Ëš, 30Ëš on the x-axis. In addition, the air flow velocity is also varied from 20, 30, 40, 50, 60, 70 km / hr with an air inlet temperature of 30ËšC. The hot fluid variable is fixed with an inlet temperature of 50ËšC and a mass flow rate of 8lpm.From the results of research that has been done, it was found that the effect of air velocity is proportional to the temperature distribution of the hot fluid on the radiator. The best position to absorb heat is the position of the radiator with an elevation angle of 60Ëš to the x-axis with a maximum heat transfer that occurs 7436.38 W. Meanwhile, the maximum pressure drop occurs at 30Ëš installation with a value of 461.084 Pa.
