Simulation Study on the Motion of Dust Particles in Traveling Wave Electric Curtain Photovoltaic Panel

To reveal the mechanism of the directional transport of dust particles in the traveling wave electric field. In this paper, by establishing the mathematical model of the spatial electric field distribution above the electric curtain surface, giving the mathematical description of the spatial electric field distribution, studying the electric field distribution law of the traveling wave electric curtain, using COMSOL Multiphysics multi-physics field simulation software, coupling the results calculated in the AC/DC module to the fluid flow particle tracking module, using numerical simulation to track the particle motion, studying the effect of external applied voltage and particle diameter on particle motion is investigated. The trajectory of single particle motion at different starting positions and different electric field frequencies is studied, the conditions required for directional transport of dust particles are proposed, and the transport mechanism of traveling wave electric curtain is explained.
