Abstract
Open tires are one of the typical characteristics of formula cars. This structure will bring some difficulties to the design of aerodynamic devices, the main reason of which is the turbulence generated by open tires. How to overcome the tire turbulence is the key technical problem of formula aerodynamic design. This article discusses how to use the vortex generated by the strake to guide and control the tire turbulence, and use CFD to verify. The results show that the leading edge vortex generated by the strakes can indeed improve the negative lift characteristics of the vehicle bottom.
