给出了重力作用下分散液滴沉降过程中分散相含率和滑移速度的经验公式。对来自14个不同数据源的29个液/液体系的998个实验结果的分析表明，液滴群的滑移速度是由液滴直径和系统的物理性质给出的：在很大的持液率(0.01到0.76)和雷诺数(0.16到3169)的范围内，滑移速度的实验值和预测值都很好地符合。
An empirical expression for the prediction of dispersed phase hold-up and slip velocity in droplet dispersions settling under gravity is presented. Analysis of 998 published experimental results for 29 liquid/liquid systems from 14 different data sources shows that the slip velocity of the drop swarm is given in terms of drop diameter and physical properties of the system by: Good agreement between experimental and predicted values of slip velocity is obtained over a wide range of hold-up (0.01 to 0.76) and Reynolds number (0.16 to 3169).
