Numerical Simulation of Electrostatic Charging Droplets in Microfluidic Devices
Publié en 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.
