气液两相管流流型识别理论研究进展

综述了气液两相流流型识别理论及方法的研究进展。首先探讨了流型划分问题，然后针对水平管路、垂直管路及摇摆管路介绍了两相流流型转换机理及转换的边界条件；对于流型的在线识别，介绍了基于波动理论、神经网络和图像处理的流型识别方法。最后提出了气液两相管流流型识别中亟待开展的理论研究方向。

The Development of Gas-liquid Two-phase Flow Regime Identification in Pipe

This paper sums up the indirect, objective theories and methods of gas-liquid two-phase flow identification. For the flow regime map and the transition criteria, the mechanism and boundary condition of the transition in the horizontal, vertical and the roiling pipes is introduced. While in online identification, the main researching outcome of the fluctuating theory and the image processing are introduced. Finally the problems in the research of the gas-liquid two-phase flow pattern identification and the emphasis of future investigation are put forward.
