摘要

液滴在外加电场中的变形是一个被广泛研究的现象,是涉及液滴电致动的微流控操作的重要组成部分。本文探讨了电场作用下液滴变形的一般数值公式。给出了两种不带自由电荷的理想介质的解法。首先将数值解与小变形的渐近解析结果进行比较,以评估该方法的准确性。在此之后,提出了变形的动力学特性,以表征受电场阶跃变化的液滴的典型响应时间。研究结果为模拟液滴的动态响应和控制策略提供了基础,并可能为基于电润湿的微流控操作提供重要的见解。

Finite Element Simulations of Transient Droplet Deformation in an Electrical Field
Deformation of droplets in an externally imposed electrical field is a widely studied phenomenon, and is an important component of microfluidic operations involving electrical actuation of droplets. In this study, we explore a general numerical formulation for the deformation of droplets under an imposed electrical field. The solution is presented for two perfect dielectrics carring no free charge. The numerical solutions are first compared with an asymptotic analytic result for small deformations to assess the accuracy of the method. Following this, the dynamics of the deformation are presented to characterize the typical response times of droplets subjected to a step change in the electric field. The results provide the basis for modeling the dynamic response and control strategies for manipulating the droplets, and may provide considerable insight into microfluidic operations based on electrowetting.
