CFD Simulation Strategy for Hypersonic Aerodynamic Heating around a Blunt Biconic

The design of the thermal protection system requires high-precision and high-reliability CFD simulation for validation. To accurately predict hypersonic aerodynamic heating, an overall strategy based on mutual selection is proposed. Foremost, grid criterion wall cell Reynolds number developed. Subsequently, dependence turbulence model discretization scheme considered. It suggested that appropriate value 1 through careful comparison between one another with available experimental data. excessive cells not recommended due to time-consuming computation. can be seen from results combination AUSM+ Spalart-Allmaras has highest accuracy. In this work, heat flux error stagnation point within 1%, average relative 10%.
