Physical Models for Supersonic Turbulent Boundary Layer Structure

Abstract

An experimental program was carried out to study the detailed structure of supersonic turbulent boundary layers. The experiments were designed to elucidate physical models and mechanisms that are particular to compressible turbulence, such as the effects of compressibility on the nature of the large- scale motions, the scaling laws for high Reynolds number supersonic turbulent flows, direct compressibility effects that cause the exchange of turbulence energy among the vorticity, entropy and sound modes, and the transport of heat and momentum by compressible turbulent motions. A description of the new optical experimental tools that were developed is included. (EDC)
