提出了描述剧烈搅拌液-液分散体系中液滴破碎和聚结的唯象模型。基于这些模型，破碎和聚结速率函数的开发和用于解决一般人口平衡方程描述液滴在连续流动容器中的相互作用。模型的参数进行评估，通过比较与实验数据的滴尺寸分布和混合频率在连续流容器中获得的操作条件的范围内。实验观察和模型之间的有利协议是令人鼓舞的，该模型是适合于预测分散性能，如液滴尺寸分布，界面面积和混合频率。
Phenomenological models are proposed to describe drop breakup and coalescence in a turbulently agitated liquid-liquid dispersion. Based on these models, breakage and coalescence rate functions are developed and used to solve the general population balance equation describing drop interactions in a continuous flow vessel. Parameters of the models are evaluated by comparison with experimental data on drop size distributions and mixing frequencies obtained in a continuous flow vessel over a range of operating conditions. The favorable agreement between experimental observation and the model are encouraging that the model is suitable for predicting dispersion properties such as drop size distributions, interfacial areas and mixing frequencies.
