An extended mixing-length hypothesis which uses an integral form of the kinetic energy-of-turbulence (IKET) equation has been assessed for its applicability to compressible transpirational or compressible nonadiabatic roughwall boundary-layer flows. Results are presented and discussed for a sharp cone with sand grain roughness and a flat plate with transpiration, both at supersonic Mach numbers, as well as a grit-blasted hemisphere-cylinder in low hypersonic flow. The results indicate that the IKET-based analysis accurately predicts the salient features of both transpirational and rough wall compressible flows. The addition of the IKET equation, which permits the streamwise computation of a parameter normally taken as constant in conventional mixing-length analyses, embodies the extended mixing-length hypothesis with considerably more capability than that possessed by conventional mixing-length approaches.
