Previous studies on emulsification have used the maximum drop size (d_max) or Sauter mean diameter ( ) to investigate the effect of viscosity on the drop size distribution (DSD), however, these parameters fall short for highly polydispersed emulsions. In this investigation (Part I), the steady‐state DSD of dilute emulsions is studied using of silicon oils with viscosities varying across six orders of magnitude at different stirring speeds. Different emulsification regimes were identified; our modeling and analysis is centered on the intermediate viscosity range where interfacial cohesive stresses can be considered negligible and drop size increases with viscosity. The bimodal frequency distributions by volume were well described using two log‐normal density functions. © 2018 American Institute of Chemical Engineers AIChE J, 64: 3293–3302, 2018

关于搅拌容器中稳态液滴尺寸的分布。第一部分：分散相粘度的影响

以前的乳化研究使用最大液滴尺寸（d _max）或Sauter平均直径（ ）以研究粘度对液滴尺寸分布（DSD）的影响，但是，对于高度多分散的乳液，这些参数不足。在本研究（第I部分）中，研究了使用粘度在六个搅拌速度范围内在六个数量级上变化的硅油的稀乳液的稳态DSD。确定了不同的乳化方式；我们的建模和分析以中间粘度范围为中心，在该范围内，界面内聚应力可以忽略不计，并且液滴尺寸随粘度而增加。使用两个对数正态密度函数很好地描述了体积的双峰频率分布。©2018美国化学工程师学会AIChE J，64：3293–3302，2018
