热防护材料气固界面传热传质问题研究进展

Thermal Protection System (TPS) is essential for safe and efficient flying of hypersonic vehicles, and one of the major challenges is the complex non-linear coupling phenomena at the interface between the surrounding high enthalpy non-equilibrium environment and the thermal protection materials. The chemical reactions at the interface, including surface catalysis, oxidation and ablation, are concurrently conjugated with flow and heat transfer at the interface, significantly affecting TPS performance. This paper presents a state-of-the-art overview of flow and heat transfer coupling mechanism investigations at the gas-solid interface for typical thermal protection materials from four categories:experimental, theoretical, multiscale numerical simulation and artificial intelligence methods. A brief summary and outlook of the future challenges for aerothermodynamics research with heat and mass transfer coupling effect at the gas-solid interface is proposed.
