Abstract: To investigate the aerodynamic characteristics of FSAE cars under corner conditions,a simplified FSAE model is established and the overset mesh method is used to simulate the straight and corner conditions.The Skid Pad road experiment is conducted and verified with numerical simulation.The results show that the aerodynamic force varies significantly in corner conditions,in which the aerodynamic drag increases by 1.5% and the aerodynamic downforce increases by 6.5% compared to a straight condition.The additional aerodynamic moments generated in corners will cause the racing car to understeer.The surface pressure distribution of the body inside and outside the corner is asymmetrical.The existence of roll angle is the main reason for the increase of the lower pressure of the diffuser and underbody.The steering angle of front wheel affects the movement of front wing vortex and result in a loss of downforce of front wing.In Skid Pad experiment,the downforce of real racing car stands at 121.9 N,the error approximately 1.6% compared with the simulation.
