Abstract: The collection mechanism inside the Electrostatic Precipitator System (EPS) is determined by the electric field, the fluid flow and the particle motion. In this study, the collection phenomena inside a wire-pipe type EPS were simulated by coupling the Electrohydrodynamics (EHD) simulation with the particle dynamics. The presented numerical method was verified by comparing to the analytical solution for an electric field and to the available numerical results for a dust collection of wire-plate type EPS. From the present EHD simulation, the collection mechanism of the wire-pipe type EPS was investigated for various operating conditions.

Keywords: EHD simulation; electrohydrodynamics; electrostatic precipitator; corona discharge; electric field; fluid flow; particle motion; dust collection; wire pipes; particle dynamics.
