WebJan 21, 2024 · In the wake of of a lifting surface, you'd inevitably find vortices. Even if a body or surface is non-lifting, vortices will also be present in the wake due to the shearing effect … WebAbove the Re value of 188.5, the flow becomes three-dimensional, with periodic variation along the cylinder. Above Re on the order of 10 5 at the drag crisis, vortex shedding becomes irregular and turbulence sets in. When a single vortex is shed, an asymmetrical flow pattern forms around the body and changes the pressure distribution.
