The animation of stream-function and vorticity contours is shown below for the case of zero pressure gradient boundary layer flow excited by a time-harmonic simultaneous blowing suction exciter. The position of the exciter is marked in the animations by an arrow. The non-dimensional frequency (F=2πf/νU) is 10-4. The results are shown for three different indicated amplitudes of excitation.
