Abstract

An analytical approach toward numerical calculation of the three-dimensional turbulent boundary layer on a sharp cone at incidence under supersonic flow conditions is presented. The theoretical model is based on implicit finite-difference integration of the governing three-dimensional turbulent boundary-layer equations in conjunction with a three-dimensional scalar eddy viscosity model of turbulence. Comparison of the present theory with detailed experimental measurements of the threedimensional turbulent boundary-layer structure (velocity and temperature profiles), as well as surface streamline direction (obtained via an oil-flow technique), reveals good agreement.
