Study and Numerical Simulation of Particle Collection and Trajectory of Particle Motion in a Duct-type Electrostatic Precipitator with Seven Circular Corona Wires

Abstract

An electrostatic precipitator (ESP) is an industrial equipment used for many years. Its main objective has been to mitigate the environmental impact due to the emission of gases that are produced in large industries. Mathematical models have been established for most of the physical phenomena that happen inside ESP. In this research work, the ESP geometrical dimensions are defined based on an ESP prototype, for instance, flat collecting plates and seven circular corona wires are used, and the corresponding models, parameters, operating conditions, and boundary conditions are described and simulated in a Multiphysics software. As relevant results found are the resolution of the transport equation and trajectory of particle motion. Besides, a comparison among the models for particle charging is shown in the results section, emphasizing when the particle radius is about 0.2 μm, where Lawless's model is used as a reference, which has been mentioned in most research works.
