为建立自主的多相流动数据库，在水平环道中进行了一系列水—气两相、油—气两相和油—水—气三相流动试验。本文测量了各相流动中由于摩擦而产生的压力损失，计算了压差梯度并作了比较；观察了各相流动中的流型，描述了各种流型的发生、发展和变化及其与流动介质的关系，并作了相互比较。
In this paper, a series of experiments, includingwater-gas, oil-gas two-phase, and oil-water-gas three-phase flows inhorizontal pipelines were carried out, in order to set up a databaselibrary of multiphase flow and to compare with each other. The pressuredrops due to friction were measured, the pressure gradients werecalculated and compared, the evolution and transition of flow patternswere observed, analyzed and compared for the different kinds of phases.
