Review of automotive aerodynamics research based on physical models

Automotive aerodynamics involves fundamental fluid dynamics problems such as turbulence flow past bluff bodies, flow instability, flow separation and control, fluid-structure interactions and noise, and so on. In this paper, we review the research progress of aerodynamics based on physical models at home and abroad, introduce the achievements of previous studies on aerodynamics, flow field research, flow control, calculation and experiment, multi-vehicle aerodynamics, pollution, wind noise, etc., and investigate the shortcomings of the present studies. Finally, we discuss the research directions of vehicle aerodynamics in the future.
