Aerodynamics plays a vital role in racing, making it one of the primary investigations done by the racing team and researchers to investigate how the aerodynamic phenomenon may occur around the car during maneuvers to make it an advantage. This research describes the aerodynamic phenomenon around racing conditions using steady CFD simulation for a simplified racing car without any interaction with another car, followed by aerodynamic simulation on the interaction between two cars, including approaching and passing conditions. The turbulent phenomenon is modeled by solving the Reynolds-averaged Navier-Stokes with Kepsilon turbulence model to describe the outer portion of the boundary layer as well as the wake regions of the boundary layer. The value of drag of the rear car and the downforce are reduced as the consequence of the wake while the front car experiences an increase of drag value as the rear car is approaching closer. The research is targeted to obtain the best possible scenario for the less advantaged following car.
