Review of Fundamentals of Electrostatic Precipitators and Ionized Flows

Abstract

Fundamentals of electrostatic precipitator (EP) and electro fluid dynamic flows are reviewed. First, a system of basic equations governing electrohydrodynamic ionized flows is presented. Based on the basic equations, the three-dimensional flow interaction for tuft or point corona for industrial EPs was investigated using both laminar and turbulent flow models. The secondary flow distribution based on laminar flow model forms a pair of organized donut-shaped rings generated from every corona or tuft points, while a pair of rings is less organized for turbulent flow model. Other analysis results for environmental improvements and plasma flows are briefly reviewed.
