    • Abstract
  • The supersonic turbulent plate ablation test technology is an important method in arc-heater to study the ablation characteristic of thermal protection materials. In order to study the change of the flow field during the supersonic turbulence plate ablation, a numerical simulation method based on N-S equation is adopted. The simulation results of the initial model surface parameters are in good agreement with the experimental results. Then, the flow field simulation about the model contour is carried out in the experimental process, which is compared with the experimental flow field. The changes of surface pressure and heat flux on the model are analyzed. According to the analysis, if the maximum ablation position is in the high heat flux region of the initial model, the ablation rate can be calculated by using the maximum ablation amount.
