Multi-scale model of high-enthalpy flow/TPS interaction was established to obtain high-fidelity aerothermodynamics of high-speed spacecraft. CFD and MD techniques were integrated to simulate high-enthalpy flow and interfacial chemistry correspondingly. This new model was used to predict catalytic heating to TPS materials and computed results are consistent with previous experiments.
