Abstract: With the new demand for high speed and long endurance of future near-space hypersonic vehicle, the interaction between high-temperature flow and thermal protection system of near-space hypersonic vehicles is prominent under extreme mechanical and thermal conditions, causing such high-temperature interface effects as heterogeneous catalysis at the gas-solid interface. The theoretical modeling and numerical research history of interface heterogeneous catalysis in hypersonic vehicles are recalled. For interface heterogeneous catalysis modeling, the specific rate efficiency model, the phenomenological model with micro- or meso-scale properties, and the cross-scale model based on microscopic theoretical simulation are reviewed in details. The research progress of modeling, mechanism and application related with the interface heterogeneous catalysis effect in the authors' team are summarized. Focusing on the future hypersonic vehicle design requirements for weight reduction, range extension, and conformal shape, the key directions of follow-up research are further proposed to support the lightweight and low-redundancy design of thermal protection systems.

Key words: hypersonic, high-temperature interface effects, heterogeneous catalysis, thermal protection system, computational fluid dynamics, aerodynamic heating, combined thermal phenomena
