Abstract
In this study, the performance of electrocoalescence in a microfluidic device was investigated through numerical simulations. The microfluidic device consisted of two immiscible fluids, a continuous phase, and a dispersed phase, which were modeled as incompressible Newtonian fluids. The interface between the two phases was tracked using a phase-field model. A flow-focusing geometry was employed to crate water droplets in oil. The dispersed droplets were then pass over a set of electrodes. The merging of two adjacent droplets in the microfluidic device was observed by applying a constant electric field. The voltage of 60 V is the lowest voltage at which the regular merging of pairs of drops...
