Abstract

Electrostatic Precipitators (ESPs) are one of the most commonly used air-cleaning devices. It is essential to study different configurations of collecting and discharging electrodes which leads to improving the performance of ESPs. Many studies are running projects on improving the existing models in many approaches. One area of improvement is the shape of the electrodes. This paper aims to investigate the wavy configuration of collecting electrodes with different sizes of corona electrodes in a single-stage ESP. The range of different corona radius sizes (0.07-0.6 mm) in wavy plates (WPs) are used and compared to flat plates (FPs) using the COMSOL Multiphysics simulation tool. The consequences of this work show the influence of changing the corona radius size on the electric potential distribution, fluid flow velocity distribution, electric field strength, current density distribution, space charge density distribution, and particle collection efficiency when wavy collecting electrodes are used.
