线—板电晕放电电流体模拟方法研究（英文）

To simulate the electro-hydrodynamics of wire-plate corona discharge at different voltages accurately,a simulation method,which relates the definite radius and initial velocity of a jet source to the amplitude of discharge voltage,is developed.Firstly,a model of the electro-hydrodynamics is established by the Matlab software using the governing equations discretized with the finite difference method.Secondly,the electric field strength and current density are simulated and the radius and initial velocity of a jet source at different voltages are determined.Finally,the discharge electro-hydrodynamics is simulated using the determined boundary conditions.Compared with using a conventional method,using the proposed method can obtain a wind velocity with smaller errors from the experimental and theoretical wind velocities: the errors between simulated wind velocity and its theoretical counter part at 45 kV and 50 kV decrease from 9% and 6.25% to 1.7% and 1.56%,respectively.Thus,the proposed method is feasible for the existing discharge models.
