Numerical analysis of the different parameter corona discharge in an electrostatic precipitators

摘要

The obective of this work is the study of corona discharge in two plans-wire configuration. The physics of discharge was investigated by solving partial differential equations. The discharge characteristics were obtained and analyzed by a combined technique of iterative calculation based on the finite element method (FEM) for this a simulation model has been developed by Comsol Multiphysics software to study and determine the influence of the wire radius and the effect of the spacing between the wire and the collection plate (the height H) on the important parameters of the corona discharge, namely the distribution of electric potential, electric field, the current density and space charge density.
