The ability of the unsteady bleed technique to control the asymmetry of the steady tip vortices separating from a forebody model is demonstrated. Mean velocity profiles measured behind the forebody model at α = 45 deg and Re = 6.3 x 10 3 clearly show the exponential spatial growth of the disturbance in the wake. This exponential growth is consistent with a spatial type of flow instability. The type of spatial instability governing the flow determines the behavior of the vortex system. The… CONTINUE READING
