Abstract This review addresses four key themes in automotive aerodynamics: flow instability in the wheel region, the aerodynamic characteristics of rims, the aerodynamic behavior of tires, and drag reduction strategies based on flow control around the wheels. The wheel region, comprising the tire, rim, and adjacent aerodynamic components, typically represents the major source of vehicle drag owing to the inherently complex flow generated by wheel rotation, tread geometry, and rim design, which gives rise to flow separation, vortex shedding, and turbulence. Drawing on a broad body of experimental and numerical research, this review elucidates the mechanisms More >
