The understanding of hydrodynamic forces around particles, drops, or bubbles moving in Newtonian liquids is modestly mature. It is possible to obtain predictions of the attractive–repulsive interaction for moving ensembles of dispersed particulate objects. There is a certain intuition of what the effects of viscous, inertial, and surface tension forces should be. When the liquid is non-Newtonian, this intuition is gone. In this review, we summarize recent efforts at gaining fundamental understanding of hydrodynamic interactions in non-Newtonian liquids. Due to the complexity of the problem, most investigations rely on experimental observations. However, computations of non-Newtonian fluid flow have made increasingly significant contributions to our understanding of particle, drop, and bubble interactions. We focus on gravity-driven flows: rise or sedimentation of single spheroidal objects, pairs, and dispersions. We identify the effects of two main rheological attributes—viscoelasticity and shear-dependen...

非牛顿液体中气泡、液滴和粒子之间的流体动力学相互作用

对在牛顿液体中运动的粒子、液滴或气泡周围的流体动力的理解还算成熟。对于分散的颗粒物体的运动系综，可以获得对吸引-排斥相互作用的预测。对于粘性力、惯性力和表面张力的影响应该是什么，有一定的直觉。当液体是非牛顿流体时，这种直觉就消失了。在这篇综述中，我们总结了最近在获得对非牛顿液体中流体动力学相互作用的基本理解方面所做的努力。由于问题的复杂性，大多数调查依赖于实验观察。然而，非牛顿流体流动的计算对我们理解粒子、液滴和气泡相互作用做出了越来越重要的贡献。我们专注于重力驱动的流动：单个球状物体、成对和分散体的上升或沉降。我们确定了两种主要流变属性的影响——粘弹性和剪切依赖性……
