  • A numerical method was developed to simulate the transient control ablation process by transpiration cooling.The influence of surface ablation and charring of thermal protective structure on cooling performance and the mass losses due to the ablation and charring was considered.In order to exactly predict the performance of the control ablation and cooling process,the influences of heat flux intensity,coolant injection velocity,initial temperatures of porous matrix and coolant on the cooling effect were discussed.
