Simulation of corona in wire-duct electrostatic precipitator by means of the boundary element method

A new approach for modeling the space density and the electric field distribution in electrostatic precipitators is presented in this paper. Two numerical techniques are used iteratively until a self-consistent solution is obtained: the boundary element method, for evaluation of the electric potential; and the characteristic method, determining the charge distribution. This hybrid approach is applied to simulate the electrical conditions in a wire-duct electrostatic precipitator and obtained results are compared with the experimental data.>
