Analysis of electric field and current density in an electrostatic precipitator
Résumé
This paper aims at analysis of the monopolar ionized field in an Electrostatic Precipitator (ESP). The corona parameters are analyzed by a combined iterative computational technique based on the Finite Element Method (FEM) and Charge Simulation Method (CSM). We proposed the introduction of a potential corresponding to the critical minimum ionization field directly in the finite element formulation as a Dirichlet condition. The computational model is validated by a comparison with experimental measurements of current density and electric field and with data from the electrostatic precipitator literature on a simple system.
