Numerical Simulation of Re-entrained Particle Migration for Double Cylinder Type Electrostatic Precipitator

Abstract

 Collection of low resistive particulate matter (PM) generated from marine engines or from diesel generators with conventional electrostatic precipitators (ESP) has been known to be difficult. Therefore, a double cylinder type ESP is suggested to remove diesel exhaust particles. The present major focus regarding double cylinder type ESPs is to study the numerical simulation for the aerodynamics behavior and the re-entrained particle motion. The ESP consists of three electrodes, which are the high voltage saw electrode, grounded hole punched electrode and grounded electrode. Numerical simulation results show that re-entrainment of diesel particles can be suppressed with this double cylinder ESP configuration.
