The development of the National Numerical Windtunnel hypersonic flow simulation software HyFLOW is of huge significance in breaking the technical barriers of similar foreign software. A comparative study with the foreign DPLR software is conducted, and the main methods of the HyFLOW solver such as the numerical method, the physical and chemical models, and the calculation model of the wall catalytic characteristics are systematically introduced. Subsequently, numerical verification of the partial catalytic wall model is executed with a typical example, and finally the numerical simulation of the hypersonic aerothermal characteristics is performed based on the standard 146-mm reentry capsule model in the LENS wind tunnel test. The results show that the HyFLOW software has high aerodynamic calculation accuracy in simulation and evaluation of hypersonic thermochemical non-equilibrium flow, equivalent to that of the similar foreign DPLR software, while the calculation accuracy of aerodynamic heating under the wall catalytic conditions is reliable, with high credibility.
