Transition Run-Out Calculations for a Compressible Boundary Layer with Wall Cooling

Abstract

An analytic model developed for the study of transition in a compressible boundary layer is used to make comprehensive transition run-out calculations for Mach numbers between 0 and 12 and wall temperature ratios between 0.05 and 1.2. Calculated results for the transition Reynolds number and the minimum critical Reynolds number for a growing boundary layer are compared with previous calculations for a frozen uniform parallel flow and with experimental transition results. The theory predicts the beginning of transition at the outer edge of the boundary layer for hypersonic Mach numbers, in agreement with experimental findings.
