The influences of concave streamline curvature and bulk compression on a turbulent boundary layer in a supersonic flow were studied. The effects of curvature and compression were identified by comparing two flows with identical pressure distributions but different amounts of curvature. The effect of the pressure rise was to increase the wall stress and amplify the Reynolds stresses. The influence of curvature complemented the destabilizing effect of the compression, and the larger the curvature the greater the increase in the wall friction and Reynolds stresses in the boundary layer.
