Abstract

Modeling the interaction between the field flow and solid material has been an important research topic in the broadfield of hypersonic aerothermodynamics. The modeling is typically done by coupling CFD solver and the material response solver. In this research, Kentucky Aero Thermodynamics System Universal Solver (KATS-US) which employs the unified approach is used. In this paper, air-carbon ablation model (ACA model) and sublimation model are implemented to account surface chemical reactions such as oxidation, nitridation, and sublimation. The surface chemistry models in KATS-US are used to conduct simulation of the two material response test cases. The first one is done by considering only surface chemistry model, and the second case is done by considering both gas chemistry model and surface chemistry model. The results of temperature, mole fraction profiles are presented to discuss about the effects of the models.
