| Abstract: | In order to analyze the heat transfer in the regeneratively cooled scramjet, three-dimensional internal CFD platform and the computational program of domestic aviation kerosene properties are used together to develop three-dimensional thermal evaluation code .The code was used for Ma=4.9 operating condition as well as Ma=5.86,numerical results show the local high temperature areas in scramjet.The code was also used to study the effects of coolant distribution on the scramjet cooling. |
