摘要: 为了对再生冷却超燃冲压发动机进行热分析,结合三维燃气流场计算软件平台、国内航空煤油物性计算程序,发展了三维热分析计算程序.在Ma=4.9和5.86两种工作状态下,对再生冷却超燃发动机整机进行了三维热分析,得到了发动机局部高温区位置,并研究了冷却剂流量分配对发动机冷却的影响.Abstract: 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.
