Application of Fluid Dynamics in the Formula One car: Exploring automobile air drag force and model design principles

Formula one racing is one of the best sporting events in the world, in addition to the driver’s driving skills, the performance of the vehicle also plays an important role in this race. The application of fluid mechanics and aerodynamics in vehicles has greatly improved vehicle performance, maneuverability and stability, it can reduce the effect of air drag force on the vehicle and convert the air drag force into a force that is beneficial to the vehicle. To achieve this, it must be started with the design of the vehicle itself. This article will start from the basic application theory of fluid mechanics and aerodynamics in vehicles, and the composition of aerodynamics components, make a model based on the 2018 Formula one car as a reference, and then use CFD (Computational Fluid Dynamics) software Ansys workbench to conduct simulation verification and analysis. Looking to the future from now on and drawing conclusions.
