Numerical Evaluation of Electrohydrodynamic Flow and Particle Concentration Effects on the Wire-Plate Electrostatic Precipitator Efficiency
Journal Title: Applied Electromagnetics - Year 2022, Vol 10, Issue 2
Abstract
In this paper, a two-dimensional computational model is implemented to study all the necessary phenomena in a simple one-stage plane depositor by considering the interactions between the electrostatic field, the flow field, the charge of the particles and their turbulent motions. In the first step of this paper, while presenting the connections between electrostatic fields, particle dynamics and fluid dynamics, the mathematical model of the corona field, air flow and particle motion is explained. In the following, the electrical conditions (electric field and space charge) and the induced flux pattern are analyzed by the interaction of ion wind and the main gas flux in the studied model. Also, while examining the path of movement and accumulation of particles, their sediment distribution in the channel is investigated and the partial efficiency of particles with different diameters is calculated. In the following, the effect of electrohydrodynamic flux on the efficiency of the equipment is investigated. Finally, considering the normal logarithmic distribution for particles at the input of the sediment channel, the effect of different concentrations of particles at the input on the overall efficiency of the equipment is analyzed. This model is simulated in COMSOL software.
