油水两相分层流动的压降研究
Study On Pressure Drop of Oil-Water Stratified Pipe Flow
-
摘要: 提出了一个考虑相界面相互作用的油水两相分层流动的压降模型, 分析了游离水层的高度和压降的变化规律, 并用白油/水两相流的实验数据作了验证, 其模型和测量的学误差的小于15%。Abstract: A pressure drop theoretical model for oil-water stratified pipe flow is presented and analyzed in this paper, considering the effect of interaction at oil-water interface. The model is validated with experiment results of white oil and water two-phase pipe flow, and the total error including model prediction and instrument measuring inaccuracy is not more than 15%.
