摘要
介绍了近年来通过压力(压差)波动过程实现气(汽)液两相流流型识别的最新研究成果.重点介绍了两相流流型的流型图、流型转换准则、压力波动机理以及不同流型识别方法,并对不同流型识别方法进行总结和分析,指出了流型识别方法现在存在的问题及今后的研究方向.
Studies on flow regime identification of two phase flow according pressure fluctuation signal in recent years have been reviewed. This paper mainly discusses the flow regime map for two phase flow, the flow-transition criteria, the mechanism for two-phase parameter fluctuation and the methodology of regime identification, different flow regimes identification methods are discussed in detail, the actual issue are the research advance are discussed.
