Abstract: Industrial simulation software for high-speed flows is one of the core tools in the aerospace simulation fields. Based on the National Numerical Windtunnel project, the Computational Aerodynamics Institute of the China Aerodynamics Research and Development Center has developed an industrial CFD simulation software for high-speed flows with independent intellectual property rights, abbreviated as NNW-HyFLOW. The software integrates modern large-scale industrial software design methodologies, and is developed based on structured/unstructured grid finite volume solvers and large-scale parallel computing technologies. It has established a series of autonomous model algorithms to simulate complex physical effects in high-speed flows, including unsteady flows of high-maneuver flight, high-temperature nonequilibrium effects, high-altitude rarefied slip effects, turbulence and transition with high Reynolds number, ionization and radiation of high-enthalpy gas. The software features a user-friendly interface and excellent compatibility with domestic hardware environments, enabling comprehensive and efficient prediction of aerodynamic characteristics, aerodynamic heating environments, plasma electromagnetic characteristics, target radiation characteristics, and aerodynamic optical effects for various complex-shaped flight vehicles. Validation through various standard model cases and complex engineering applications demonstrates that the software exhibits robust, efficient computation, reliable accuracy, strong engineering practicality, and superior overall performance. By introducing the software design methodology, core functions, and engineering applications, this article aims to help professionals better understand the HyFLOW software, thereby promoting the development of the high-speed flow simulation field and the domestic autonomous industrial software ecosystem.

Key words: National Numerical Windtunnel, thermochemical nonequilibrium, high-speed flow, Computational Fluid Dynamics, simulation software
