Control of a Separated Flow over a Smoothly Contoured Ramp Using Vortex Generators
In this communication, we study experimentally the modification of a boundary layer by a line of four cylindrical vortex generators. We show how the base flow modification and, specifically, the first non-linear mode (the zeroth mode) can lead to new parameters characterizing the efficiency of the vortex generators. We finally apply the vortex generators to a smoothly contoured ramp showing a clear delay of the separation when the parameters are properly chosen.
