摘　　要：介绍了推力室液膜冷却机理,并对膜冷却相关研究进行了综述,在总结已有研究成果的基础上建立了一套液膜冷却推力室传热计算模型,采用该模型对某液膜冷却推力室进行了传热计算,地面试车测量值与壁温计算值基本一致。This paper introduced the mechanism and research status of film cooling. A heat transfer computational model for liquid film cooling thrust chamber was established. The model was used to perform a calculation of the heat transfer in a liquid film cooling thrust chamber. The calculated results agree well with the experimental data.
