| Abstract: | The complicated phenomena in the porthole region of vehicle, which is coupled with thermolysis/ablation of thermal protection material and heat transfer in different materials,is numerically studied in this paper. The different characteristics of temperature increase at some important positions of the porthole region are respectively given under both constant heating and variable heating on the upper surface of the porthole. And the mechanism of heat transfer is given, which is significant to the design of local thermal protection structure. |
