| 摘 要： | 对油－水混合物在垂直管道中的流动进行了实验研究。将漂移流动模型进行了改进，并运用于实验数据的处理中。通过非线性曲线拟合的方法确定了关键参数，建立了持水率预测的新方法。利用公开发表的数据对新建模型进行了验证。研究结果表明：油、水的滑脱程度受到油、水配 比及混合物平均流速的影响，且在低含水率及低流速条件下尤为严重；新建模型较文献中已发表的模型具有更高的精度，可对不同来源的数据进行较为准确的预测。

| Abstract: | Oilcen- water two-phase flows in vertical pipes were investigated theoretically and experimentally .The drift flux model was improved to analyze the experimental data. A few key parameters were determined with curve-fitting method ,and a new model was obtained based on the experimental data. It was found that the slippage between water phase and oil phase was influenced by water cut and the flow rate of oil-water mixture, and the influence was more serious under lower water cut and lower flow rate. The proposed model was validated by our data and the others ,and shows that the performance of new model was better than others published in the literature. |
