Abstract

In this paper, a two-dimensional axial-symmetric fluid model is proposed to study the negative surface discharge development on insulator with needle-plane electrode in air at atmospheric pressure. The finite-element method (FEM) is employed to solve the convection-diffusion equations for electrons, positive and negative ions coupled with Poisson's equation. Photoionization effect is considered in this model. The mechanisms of surface discharge process are discussed by considering the temporal and spatial evolution of the quantities described by the model. The simulation results of surface charge density and discharge current are also compared with experimental data based on Pockels technique.
