Abstract
The influences of concave streamline curvature and bulk compression on a turbulent boundary layer in a supersonic flow were studied. The eff ects of curvature and compression were identified by comparing two flo ws with identical pressure distributions but different amounts of curv ature. The effect of the pressure rise was to increase the wall stress and amplify the Reynolds stresses. The influence of curvature complem ented the destabilizing effect of the compression, and the larger the curvature the greater the increase in the wall friction and Reynolds s tresses in the boundary layer.
