摘　　要：热防护材料本身和复杂高温/非平衡流动环境之间的气固界面传热传质问题对高超声速飞行器服役热环境的高精度预测及热防护系统(TPS)的精细化设计至关重要。从航空航天及传热传质领域角度出发,以试验测试、理论计算、数值模拟及人工智能应用这4种典型研究范式为切入点,重点综述了国外表征高温服役气体环境/热防护材料气固界面传热传质耦合特性的主要研究手段及最新研究进展,简要总结了中国该领域的研究现状及特点,并在此基础上浅谈了现阶段热防护材料界面热质耦合特性研究的经验启示和新科学范式革命发展带来的挑战思考。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.
