水平及倾斜圆管中油水两相分层流界面波对摩擦压降的影响
Effects of Interfacial Wave on Frictional Pressure Gradient of Oil-water Two-phase Stratified Flow in Horizontal and Inclined Pipes
摘要
Abstract
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 two-phase 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.关键词
