在内径为40mm的水平管内、0.4MPa压力下进行了油-气-水三相流流型可视化的实验。描述了所观察到的各种流型的特征,并给出了流型图。可视化实验中观察到的流型有7种类型,分别为水基和油基的波状流、弹状流和分层—环状流。实验中还发现了许多在两相流动中所观察不到的新的流型结构。 The experiment of oil-gas-water three-phase flow pattern visualization was carried out under the pressure of 0.4 MPa in a horizontal tube with an inner diameter of 40 mm. Described the observed characteristics of the various flow patterns, and gives the flow pattern. There are seven types of flow patterns observed in the visualization experiment, which are water-based and oil-based wavy flow, slug flow and stratified-annular flow respectively. The experiment also found many new flow-type structures not observed in two-phase flow.
