Low Density Flow Effects for Hypervelocity Vehicles

Abstract

This work presents results for the surface pressure, drag, heat transfer and skin-friction coefficients for hyperboloids and sphere-cone shaped slender and wide-angle bodies under varying degrees of low-density flow conditions. Recently obtained surface-slip and the corrected shock-slip conditions are employed to account for the low-density effects. The flow cases analyzed include highly cooled and very long slender bodies in high Mach number flows. The present method (limited to the analysis of a perfect gas here) is found to predict various flow field quantities quite accurately when compared with the experimental data. Keywords: Slender bodies; Wide angles; Aerothermodynamics; Hypersonic characteristics; Hypersonic vehicles; Upper atmosphere; Viscous shock layer equations; Hypersonic viscous flow.
