Computational Method for Fluid Dynamic Analysis of Electrostatic Precipitator. Final Report

摘要

This project was an investigation of the applicability of new and innovative approaches to improve the design and performance of electrostatic precipitators (ESPs). Utilizing a finite-difference computational scheme, the turbulent flow field and fine-particle trajectories around an ESP collecting electrode were described. The objective of this project was to apply this analytical technique for the evaluation of the turbulent flow characteristics for four (4) collecting electrodes geometries. When coupled with electric field computations, this technique should provide a new dimension for the analysis and design of ESPs. A possible new development, the Fluid Dynamic Collector (FDC) was also investigated in this study. Preliminary indications are that the FDC may perform better than the conventional parallel plate ESP configuration. However, this prediction requires further resolution of electric field effects, and the physical arrangement of the FDC would require special installation arrangements. (ERA citation 07:018144)
