Abstract:

An experimental investigation was made of the separation phenomena on a flat plate at Mach numbers from 4.8 to approximately 6.2. Emphasis was given to determining the maximum pressure ratio obtainable on wedges and curved surfaces without separating the turbulent boundary layer. The effective Reynolds number was changed by using different length plates and by placing roughness strips on the plates. This paper also gives some characteristics of the flow after separation has occurred and gives some insight into body forces associated with separation.
