Implicit Finite-Difference Analysis of Compressible Laminar, Transitional, and Turbulent Boundary Layers along the Windward Streamline of a Sharp Cone at Incidence

Abstract

Formulation and application of a windward plane of symmetry laminar, transitional, and turbulent boundary-layer analysis is presented for sharp cones at incidence in a supersonic or hypersonic flow. The governing boundary-layer equations in the plane of symmetry are numerically integrated on a digital computer using a marching implicit finite-difference technique. A so-called invariant model of turbulence is used in a two-layer eddy viscosity-mixing length approach for calculation of the turbulent boundary layer in conjunction with an intermittency factor treatment of the transition zone. Comparison of the of the present theory with experimental data is made.
