Experimental investigation of water droplets' behavior in dielectric medium: the effect of an applied D.C. electric field
H. Bararnia and D. D. Ganji Department of Mechanical Engineering, Babol University of Technology, Babol, Iran
Abstract. In this article, the behavior of water droplets which are suspended in silicon oil is qualitatively investigated and some phenomena such as liquid's burst are reported. The movement of droplet in perpendicular line is considered while many studies have considered small droplets fluctuating between two horizontal electrodes. Additionally any deformation caused by increasing voltage was observed from start to finish until short contact occurred. As can be seen two oppositely charged drops contacting each other do not necessarily result in coalescence. Repelling can be expected occasionally. By increasing the voltage, the droplets, which spread through the domain due to frequent breakups, tend to gather in a certain line.
