Radiative Viscous-Shock-Layer Solutions with Coupled Ablation Injection

This paper describes a viscous-shock-layer analysis for investigating high energy equilibrium flowfields about blunt axisymmetric bodies. The analysis includes radiation transfer, mass injection, diffusion, and visous effects. Radiation transfer is calculated with a nongray radiation model that accounts for line and continuum radiation. The analysis can treat large levels of blowing for both stagnation and downstream flow. Results are presented for selected Earth entry conditions that demonstrate the essential features of this analysis. Particular emphasis is given to the effects of mass injection on stagnation and downstream flow. Results for both specified and coupled ablation injection are presented.
