“…Therefore physical-chemical processes can be strong enough to influence and even dominate the flow characters in the high-temperature region. The question and mechanism arouse many authors' interest [1][2][3][4][5] . The combination of kinetic energy and high speed is transformed into high air temperature and endothermal chemical processes (Figure 1), including the ionization and dissociation of atmospheric species in the high-temperature region.…”

Investigating the high-temperature effect and catalytic condition with hypersonic flow numerical research was conducted by CFD methods. For comparison, flows were calculated by using a high-temperature nonequilibrium gas model and a calorically perfect gas model. All findings showed that high temperatures alter the flow properties considerably. The flow field structure, temperature distribution, pressure distribution, etc. were different from the calorically perfect gas assumption flow. All these differences would affect the aerodynamical force and aero heat of the fly vehicles with hypervelocity. Furthermore, all conditions of non-catalytic and catalytic effects were computed and compared. The flow with catalytic conditions produces more aero heats due to an exothermic recombination reaction near the wall. The methods and computations could be used for further engineering applications and hypersonic aerodynamical research.

This paper presents a novel physics-infused reduced-order modeling (PIROM) methodology for efficient and accurate modeling of nonlinear dynamical systems. The PIROM consists of a physics-based analytical component that represents the known physical processes and a data-driven dynamical component that represents the unknown physical processes. The PIROM is applied to the aerothermal load modeling for hypersonic aerothermoelastic (ATE) analysis and is found to accelerate the ATE simulations by two to three orders of magnitude while maintaining an accuracy comparable to high-fidelity solutions based on computational fluid dynamics. Moreover, the PIROM-based solver is benchmarked against the conventional proper-orthogonal decomposition/kriging surrogate model and is found to significantly outperform the accuracy, generalizability, and sampling efficiency of the latter in a wide range of operating conditions and in the presence of complex structural boundary conditions. Finally, the PIROM-based ATE solver is demonstrated by a parametric study on the effects of boundary conditions and rib supports on the ATE response of a compliant and heat-conducting panel structure. The results not only reveal the dramatic snapthrough behavior with respect to spring constraints of boundary conditions but also demonstrate the potential of the PIROM to facilitate the rapid and accurate design and optimization of multidisciplinary systems such as hypersonic structures.
