Abstract
This research presents a simulation analysis of D.C. corona characteristics to investigate the effects of electric field distribution on corona discharge caused by different electrode geometries. A model setup with various electrode shapes is designed to evaluate the corona discharge characteristics. This model solves the electron and ion continuity and momentum equations with a drift-diffusion approximation that is coherently coupled with the Poisson equation. To explore the impact of the electric field (E.F.) on corona discharges caused by various electrode geometries (sharp, flat, and spherical) and applied voltages, the electric field dispersal was analyzed using finite element analysis (FEA). The simulation software models corona discharges with different electrode shapes (sharp, flat, spherical) and undergoing discrete applied voltages. The bi-dimensional (2D) model was constructed to investigate the distribution of the electrical field and its impact on corona discharge. Due to these simulations based on Finite Element Analysis (FEA), the dispersion of the electric field’s impact on corona discharge of various electrode geometries and applied voltage will be investigated. To elaborate on the influence of variation in applied voltage and the varied shape of electrode geometries on corona discharge, the dispersion of the electric field, electron current density, and electron density will be evaluated.
