摘　　要：在大型多相流试验环道上进行了空气水、空气HVIW150基础油试验,对水平管低液量气液分层流的流动特性进行了研究。选取了ARS模型作为界面形状模型,同时以动量平衡方程为基础,求解了气液两相流的摩阻压降,并将模型预测值与试验所测的摩阻压降作了比较分析,得出了分层流摩阻压降变化的一些规律,在低液量的分层流动中推荐采用ARS界面模型。Flow characteristics of horizontal two-phase gas-liquid stratified flows with low liquid loading are studied through both air-water and air-HVIW base oil experiments on the large-scale multiphase experimental loop. Based on measurement and observation of flow pattern,'apparent rough surface'( ARS) model is selected to calculate frictional pressure gradient with gas-liquid momentum balance equations. The predictions of the models are compared with the data measured in the experiment. Some results of pressure gradient are obtained, so ARS interfacial shape is recommended in horizontal two-phase gas-liquid flows with low liquid loading.
