摘　　要：在汽轮机湿蒸汽透平级中,湿蒸汽两相凝结流动现象的出现降低了透平级的流动效率,并且造成了透平叶片的水蚀损坏。本文针对汽轮机中的自发凝结流动,介绍了湿蒸汽两相流动数值研究发展的现状,以及西安交通大学TurboAero研究组在此方面的研究情况,以期对我国湿蒸汽汽轮机的设计以及湿蒸汽两相凝结理论的工程应用起到推动作用。The wet steam flow with homogeneous condensation in steam turbine not only degrades the efficiency of turbine, but also leads to water erosion of blades. The progress in study of wet steam flow with condensation is introduced, and some research results by the TurboAero group at Xi＇an Jiaotong University are presented. It＇s expected to promote the design of wet steam turbine and the application of wet steam theory to steam turbine industry.
