Abstract
After 1980's numerical simulation approaches have been carried out in order to establish the theory for collecting particle mechanism in Electrostatic Precipitator (hereinafter, ESP). In relation to the Finite Turbulence Diffusion Model in ESP we conducted a numerical calculation to investigate fundamental flow characteristics of Electro-Hydro-Dynamics (EHD) field. In comparison of the results of laminar flow and that of turbulence flow, some significant differences between two flow patterns are there. Especially, the secondary flows by ionic wind in turbulence are smaller than in laminar and also the distribution of effective viscosity in the duct is clarified. The predicted collection efficiency by the Finite Turbulence Diffusion Model is higher than that by the Deutsch Model.
