Abstract
Hypersonic, nonequilibrium viscous flow with ionization over nonanalv tic blunt bodies is considered. The equations which govern the viscous shock-layer flow are presented and the method by which the equations are solved is discussed. The predictions of the present finite-difference method are compared with other numerical predictions as well as with experimental data. Flows over two sphere cones are considered, the RAM C re-entry body (a 9° sphere cone at 233,000 ft and 25,000 fps) and a 7.5° sphere cone at the experimental wind-tunnel conditions of Pappas and Lee. The predictions of the present method agreed well with the experimental data and with the other numerical predictions except those of Kang and Dunn for the 9° sphere cone. Substantial differences were found between the present predictions and the more approximate predictions of Kang and Dunn for heattransfer distributions and temperature profiles.
