In order to analyze the heat transfer in the regeneratively cooled scramjet

three-dimensional internal computational fluid dynamics(CFD) platform and computational program of domestic aviation kerosene properties were incorporated to develop a three-dimensional thermal evaluation code.The code was used at Ma=4.9 operating condition as well as Ma=5.86.The numerical results show the local high temperature areas of scramjet.The code was also used to study the effects of coolant distribution on the scramjet cooling.
