On the effect of thin shear layers with flow and density gradients on small disturbances in inviscid, compressible flows

Abstract

An inner asymptotic expansion method was recently used to derive an analytical solution for the propagation of small disturbances through thin sheared flow regions. The method is shown to be applicable as well to the case when there are also density and sound speed gradients in the shear layer. Several applications of the technique are outlined and briefly discussed.
