%X A 3D numerical model based on the finite volume method is developed to simulate the entire precipitation process
inside an electrostatic precipitator (ESP). The complex coupled phenomena among the electric field, turbulent flow
field, particle charging process, and particle motion are taken into consideration for the full analysis of an electrostatic precipitator. The effect of electrohydrodynamics flow is considered for the accuracy of computation. The electric field is determined by the Poisson equation and the current continuity equation using the Kaptzov hypothesis. The discrete phase model is adopted to describe the particle motion, and the particle charge is calculated by the integration of the charging rate equation. It is found that the model can well simulate the inner characteristics and particle collection of ESP. The results show that the collection efficiency increases with the applied voltage, while the increasing inlet velocity
makes the collection process worse. It is also found that particles get most of their charges rapidly in the vicinity of the first corona electrode.
