Study of Catalytic Effects at Reentry Vehicle. MHD Heat Flux Mitigation In Irradiative Hypersonic Flow Around A Blunt Body With Ablating Carbon Surface

摘要

Two-dimensional simulations were performed with applications to surface heat flux mitigation by means of MHD interaction in hypersonic flow around a blunt body. The computational model realizes coupled solution of MHD chemically non-equilibrium irradiative airflow with taking into account heat- and mass-transfer due to ablation of carbon from the surface. It was found that serious surface heat flux reduction is possible under conditions of MHD interaction even if additional radiative heating could be present due to increase of the shock layer thickness. It was also found that uncoupled flow/radiation treatment may lead to quite different estimations of MHD-assisted heat flux reduction.
