【 摘 要 】

The wake behind an axisymmetric body rotating about an axis aligned with the streamwise direction has been experimentally investigated in a low-velocity water channel for the intermediate Reynolds number. The measurements focused on the evolution of the flow regime with two counter rotating vorticies, as a function of two control parameters, namely the Reynolds number and the dimensionless rotation rate Ω.
