Simulation of Motion of Micrometer Sized Droplets of Dielectric Water-based Paint under Air Flow and Electric Field

Wei-Wei Xu and Yong-Ming Zhang
Abstract—In the present study, the motion of the micrometer sized droplets of dielectric water-based paint in the air is investigated numerically. The effects of gravity, the inlet velocity of air flow and applied external positive DC electric field have been taken into account. In the first part, the motion of the droplets is simulated. It is found that the effect of gravity and inlet velocity of air flow can be neglected under our conditions. In the second part, the motions of the droplets under the external electric field are simulated to investigate the effect of electric field. Our results show that the external positive electric field can result the fall speed increase comparison with the condition under no electric field. It is also observed that impact time decreases as electric potential increases. The simulation results show that the Navier-Stokes equations coupled with other fields provide an effective approach to analyze the dynamic problems for liquid droplet.
