Abstract

Experimental results of turbulent separating boundary layer, subjected to nominally 2D pulsed excitation, are presented and discussed. The effect of the adverse pressure gradient on the vortices circulation and convection speed has been documented. A search for instability mechanism did not result in any that were amplified. Therefore, pulsed excitation that intermittently enhances the skin friction with optimal time lag should be explored.
