摘要
对垂直上升管内油水两相流动特性进行了实验研究,指出油包水流型向水包油流型发生转变的界限点在含水率w=0.3处.在前人研究的基础上,提出了通过实验测量得到的压力降来计算油水两相乳化液粘度的新模型.结果表明,这种计算油水乳化液粘度的方法较为精确.
The flow characteristics of water-oil emulsion in the vertical upward pipe were studied experimentally and a transitional criterion of W/O to O/W type oil-water emulsion was proposed at (φ)_w=0.3. Based on the investigation of former researchers, a new model was proposed to calculate the oil-water emulsion viscosity. The calculation results show that this new method has better accuracy.
