Currently, in the Formula Student China (FSC) competition, the aerodynamic design of the majority of teams focuses on increasing the angle of attack of the front wing as the main design method, leading to low flow field efficiency and high sensitivity to pitch and roll. This paper focuses on vortex utilization and presents an aerodynamic design for a formula student racecar based on flow control. By establishing a complete vehicle simulation platform using vehicle dynamics simulation software and computational fluid dynamics (CFD) simulation software, the aerodynamic design of the entire vehicle is carried out through aerodynamic simulation comparison. Through CFD comparison with conventional aerodynamic design racecar in the past, the aerodynamic lift coefficient and lift-to-drag ratio increased by 19.4% and 12.4% respectively, and the change in front axle aerodynamic force distribution at the same pitch angle decreased by 51.4%. This demonstrates that aerodynamic design based on flow control can effectively improve flow field efficiency and mitigate aerodynamic sensitivity.

摘要

Currently, in the Formula Student China (FSC) competition, the aerodynamic design of the majority of teams focuses on increasing the angle of attack of the front wing as the main design method, leading to low flow field efficiency and high sensitivity to pitch and roll. This paper focuses on vortex utilization and presents an aerodynamic design for a formula student racecar based on flow control. By establishing a complete vehicle simulation platform using vehicle dynamics simulation software and computational fluid dynamics (CFD) simulation software, the aerodynamic design of the entire vehicle is carried out through aerodynamic simulation comparison. Through CFD comparison with conventional aerodynamic design racecar in the past, the aerodynamic lift coefficient and lift-to-drag ratio increased by 19.4% and 12.4% respectively, and the change in front axle aerodynamic force distribution at the same pitch angle decreased by 51.4%. This demonstrates that aerodynamic design based on flow control can effectively improve flow field efficiency and mitigate aerodynamic sensitivity.
