摘　　要：气液降膜是工业中常见的传热传质过程,在很多领域中有着广泛的应用,在湿空气透平(HAT)循环的主要部件饱和器中,也有着重要的意义。本文回顾了降膜分别在气体剪切力下以及由界面相变引起的热非平衡状态下的流动稳定性及传热传质的发展现状和研究进展,总结了气液降膜流动已有的理论和实验结果,并展望了气液降膜流动技术的发展前景。Gas- liquid film falling is widely encountered in industry and also has extensive use in many fields. Especially it is also of great importance in the saturator, which is the key components for Humid Air Turbine（HAT） cycle. The development and present con- dition about the falling film sheared by gas flow and the thermal non -equilibrium effect occurred by phase change at the interface are reviewed. The theoretical and experimental results of flow stability and the heat and mass transfer of the falling film are summarized. Last the further study of gas - liquid falling film is also discussed and prospected.
