Impact of wheel rotation on the aerodynamic drag of a time trial cyclist
, 2021 Aerodynamic drag is the main resistive force in cycling at high speeds and on flat terrain. In wind tunnel tests or computational fluid dynamics simulations, the aerodynamic drag of cycling wheels is often investigated isolated from the rest of the ...

Aerodynamic drag analysis of runners
Medicine & Science in Sports & Exercise, 1976 A model is presented for the determination of aerodynamic drag forces on runners. The model consists of a series of conjugated circular cylinders, to stimulate the trunk and appendages, and a sphere to stimulate the head. Results are presented for three runners representing respectively, adult American males in the 2.5, 50 and 97.5 percentiles of the ...
