3D Numerical Study of Wire-Cylinder Precipitator for Collecting Ultrafine Particles from Diesel Exhaust
Journal Title: Informatyka Automatyka Pomiary w Gospodarce i Ochronie Środowiska - Year 2012, Vol 2, Issue 2
Abstract
A precipitator section is modeled numerically in 3D to determine the collection efficiency for diesel exhaust particulates. It consists of a circular tube and a wire electrode mounted at the center of the tube, supplied with a negative high dc voltage, while the tube is electrically grounded. The analytical solutions of Poisson and current continuity equations are implemented to obtain the ionic space charge density and electric potential distributions in the channel. Commercial CFD FLUENT software is used to solve the turbulent flow mode. Effects of some electrical characteristics of diesel exhaust particulates on collection efficiency are assessed.
