Semisimilar solutions of the unsteady compressible laminar boundary-layer equations
Abstract
The theory of semisimilar solutions, previously developed for unsteady two-dimensional incompressible laminar boundary-layer flows, is extended to the case of compressible flows. A study is made of several flows for which semisimilar solutions are possible with a view of investigating the nature of compressible unsteady separation. The solutions obtained indicate that the Moore-Root-Sears model for unsteady boundary-layer separation is valid for compressible as well as incompressible flow. In addition, the effects of Mach number and wall temperature on the moving separation point are determined.
