Abstract

The interaction of a plane, two-dimensional turbulent shear layer with a thin, flat plate located downstream from the origin of the shear layer has been studied experimentally and theoretically. The shear layer was created by two parallel air streams with velocity U//1 equals 7. 31 ms** minus **1 and U//2 equals 2. 74 ms** minus 1 and Reynolds number of 620 based on the velocity difference and the initial momentum thickness. Flow motion was visualized using a smoke wire, and measured using hot wire probes. The spatial growth of the initial instability of the non-impinging shear layer was determined from measurements of the power spectrum of the streamwise velocity componenet as a function of distance downstream.
