摘　　要：油水两相流在重力和界面张力共同作用下发生分层,由于剪切应力的作用,在管道流动中产生摩擦压降,油水两相分层流在流动参数改变时产生界面波,其对摩擦压降产生影响。实验研究水平和倾斜管道油水两相波状分层流界面波特性及其对摩擦压降的影响,并改进一维双流体模型预测摩擦压降。研究结果表明,管道倾角增加时,油水两相分层流界面波振幅增大,其对摩擦压降的影响也随之增强,改进的考虑界面波振幅的模型在不同管道倾角中的摩擦压降预测结果与实验数据吻合好。Oil and water two phases forms the stratified flow due to the combined action of gravity and interfacial forces.The frictional pressure gradient generates in the pipeline due to the shear stress.The frictional pressure gradient is influenced by the interfacial wave due to the change of flow parameters.Studied are the characteristics of interfacial waves in oil-water twophase wavy stratified flow at horizontal and inclined pipelines and the effect of interfacial wave on the frictional pressure gradient.The modified one dimensional two-fluid model is presented to predict the frictional pressure gradient.The results indicate that the interfacial wave amplitude increases as pipeline inclination increasing and the effect of wave amplitude on the frictional pressure gradient increases.A good agreement is observed of the frictional pressure gradient between predicted data obtained from the modified one-dimension two-fluid model and experimental results.
