Numerical Simulation of Electrostatic Charging Droplets in Microfluidic Devices
发布日期 2014
In this paper, the mechanism of charging process was simulated and analyzed. The simulation was conducted using COMSOL Multiphysics® software, based on the laminar two-phase flow level-set interface coupling with the electrostatic interface. Meanwhile, different parameters (such as the droplet size and surfactant) were numerical studied. Based on the simulation results, a more efficient charging design was proposed. Finally, microfluidic devices were developed using standard microfabrication technology, and the induced charge in a droplet was characterized in the devices. The experimental results agreed well with the simulation.
