Abstract
The three-dimensional flow interaction for tuft or point corona for industrial electrostatic precipitators 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. When the primary flow exists, the organized spiral motion for turbulent model is further diffused in the direction of gas flow and increased N EHD, which leads to turbulent flow. Turbulent model appears to be more appropriate for predicting the wire-plate ESP based on experimental investigation.
