摘要：

Results of 2- and 3-dimensional Particle Image Velocimetry (PIV) measurements of the flow velocity fields in narrow electrostatic precipitators (ESPs) with either a longitudinal or transverse wire electrode are presented in this work. The obtained results confirmed that the particle flow in the ESP have a strongly 3D character mainly due to applied voltage and narrow cross section of the ESP duct. It was found that several vortices were formed along and across the ESP duct. The complex character of the flow in both ESP may considerably affect the particle collection efficiency of the ESP. This issue is under investigation. (C) 2009 Published by Elsevier B.V.
