Abstract

Results of a study of the structure of a supersonic separated flow formed in the vicinity of a compression ramp are reported. At high supersonic speeds, a thin high-pressure layer may form in the re-attachment zone over the inclined wall of the ramp. The gas-dynamic quantities in such a high-pressure layer can noticeably differ from the flow quantities in the surrounding stream. The influence of Mach number (in the range of M = 3-8) and Reynolds number (laminar or turbulent mode of separation) on the flow structure is studied, and the occurrence possibility of the high-pressure layer is analyzed.
