Abstract

The paper presents preliminary computational results of surface ablation around double-cone flare geometry. The analysis is based on Park's ablation model, which is fully coupled with the non-equilibrium real gas flow model. The equations are solved using second-order high-resolution methods implemented into the in-house code CNS3D. Comparisons of the numerical and experimental results for the case without ablation are also presented. Furthermore, computational results are presented for the heat transfer coefficient, mass blowing rate and key flow features for the cases with and without ablation.
