Towards the application of the One‐Dimensional Turbulence model for the evaluation of collection efficiencies in wire‐tube electrostatic precipitators

Abstract

The One-Dimensional Turbulence (ODT) model framework for the simulation of particle-laden wire-tube electrostatic precipitators is detailed in this work by specifying initial conditions, governing equations, and the mechanism for two-way coupling between the electrostatic fields and the hydrodynamic flow. Unlike in a previous investigation [1], a two-way coupling is required due to the low electrical mobility of aerosol particles, making flow motion responsible for the appearance of electrical convective currents. The ultimate goal of this framework is to develop a method which is able to investigate the precipitation phenomenon in wire-tube precipitators, e.g., the collection efficiency, while relying on highly resolved physics.
