Abstract

An experimental Investigation was made of the flow in a laminar boundary layer in a region of adverse pressure gradient in the presence of an acoustic field. There is a significant rearrangement of the laminar flow under the influence of the sound. The strong influence of the sound on the average flow is due to the excitation of vorticity perturbations, but this does not completely explain the phenomenon.
