Strategic Reentry Technology Program. Phase 2. (STREET-AII). Volume 1. A Two-Layer Model of High Speed Two- and Three-Dimensional Turbulent Boundary Layers with Pressure Gradient and Surface Mass Injection

Abstract

A two-layer model of a three-dimensional compressible turbulent boundary layer is developed which is applicable to flows with pressure gradient and surface mass transfer. The model is based on the small cross-flow approximation in which the spreading metric is determined by the inviscid streamline pattern. A modified Mangler transformation is employed which permits transformation of the boundary layer equations to a two-dimensional form without transforming the turbulent stress or heat flux. Solution of the layer for velocity and enthalpy is obtained using mixing length theory and the thin layer Couette model. This report shows that the dynamics of the turbulent boundary layer depend on the coupling and interaction of the inner and outer layers. Several solutions and experimental comparisons are presented.
