Numerical Modelling of Flow through Perforated Plates Applied to Electrostatic Precipitator

M.R. Swaminathan and N.V. Mahalakshmi

Abstract:
The main aim of this study is to simulate numerically the flow through perforated plates in Electrostatic precipitator and compare the obtained results with the one obtained experimentally. Better flow distribution in the collection chamber of electrostatic precipitator was obtained with two perforated plates of porosity 50%, one plate located just upstream of the diffuser exit and other at some distance downstream of the diffuser entrance. Perforated plates of higher porosity do not have the capability to spread out the flow, whereas plates of low porosity lead to excessive pressure drop. Mean velocity of flow at diffuser exit obtained numerically was 4.5 m sec-1 while velocity obtained experimentally at diffuser exit was 3.75 m sec-1, with about 16% deviation. Numerical investigation of flow through perforated plates and velocity distribution in the collection chamber of an Electrostatic Precipitator was carried out using a Computational Fluid Dynamics code namely FLUENT. The effect of porosity and perforated plate location on flow uniformity and turbulence were studied and the results were compared with experimental data.
