Modeling of Trichel Pulses in the Negative Corona on a Line-to-Plane Geometry

In this paper, a 2-D time domain method is proposed to simulate Trichel pulses in the negative corona discharge on a line-to-plane geometry. Three ionic species in the ionization layer, including electrons, positive ions, and negative ions, are taken into consideration. The FEM is used to solve the Poisson's equation, while the finite volume method is used to solve the charge transport equations. Trichel pulses on a line-to-plane geometry are analyzed and compared with the measured results of a designed experiment in the laboratory. Good agreement is obtained between the calculated results and the measured ones, verifying the validity of the proposed scheme.
