Effects of Mass Transfer Into Laminar and Turbulent Boundary Layers Over Cones at Angle of Attack

Abstract

A computer program has been developed for full three-dimensional boundary-layer analysis of sharp and blunt cones at angle of attack to supersonic and hypersonic flows. This analysis includes laminar, transitional, and turbulent flows, with mass transfer of various foreign gases at the wall. The governing boundary-layer equations are integrated on a digital computer using a marching implicit finite-difference scheme. Turbulence has been modeled by a two-layer eddy viscosity-mixing length approach employing an intermittency factor in the transition region. Results of the program calculations are compared to available experimental and numerical data.
