A SURVEY OF HEAT-TRANSFER IN COMPRESSIBLE SEPARATED AND REATTACHED FLOWS

This review is concerned predominantly with flow separation in supersonic and hypersonic flow. The basic geometric configurations are the cavity, backstep, and base of a body. In the two former cases, and if the base forms an abrupt edge with the forward portion of the body contour, the position of separation is known a priori. The position of reattachment, and the shape and size of the separated region, are not known a priori and depend on the specific flow situation. Particular points of interest are the influence of a number of parameters on the heat transfer to the wall in the separated region (e. g. , Reynolds number, Mach number, angle of attack) and the correlation of the heating characteristics with these parameters. Separated flows caused by the impingement of a shock onto a wall boundary layer are not examined here.
