Inelasticity effects on the migration of a drop and pairwise interaction of drops in a simple shear flow are studied using a finite-difference front-tracking method. The Carreau-Yasuda model is used to adjust the shear-thinning behavior of fluids. Results showed that drop deformation and migration rate of drops in an inelastic system are smaller than those in a Newtonian one. It was revealed that inelasticity has larger effects for the case in which Newtonian drops suspended in a non-Newtonian phase. The time of collision process is shorter for an inelastic system in comparison with the Newtonian one. For two Newtonian drops in an elastic matrix, the results demonstrated that the drops exhibit reversible cross-flow migration at high inelasticity.

稀疏剪切非弹性流体中液滴的成对相互作用

使用有限差分前沿跟踪方法研究了在简单剪切流中液滴运动和液滴成对相互作用的非弹性效应。Carreau-Yasuda模型用于调整流体的剪切稀化行为。结果表明，非弹性体系中的液滴变形和迁移速率要小于牛顿体系中的液滴。结果表明，对于在非牛顿相中悬浮的牛顿滴而言，非弹性具有更大的影响。与牛顿系统相比，非弹性系统的碰撞过程时间更短。对于弹性矩阵中的两个牛顿滴，结果表明该滴在高非弹性下表现出可逆的错流迁移。
