Abstract :
In this paper, the particle image velocimetry (PIV) measurements of the flow velocity fields in a wire-plate type electrostatic precipitator (ESP) positive polarity were analyzed for wide range of Reynolds and electrohydrodynamic numbers, and their influence on the dust particle collection efficiency was investigated. The results show that the dust particle collection was influenced by electrohydrodynamic (EHD) secondary flow when Ehd/Re2≥1 and ReSc≥FE , where Sc is the Schmidt number and FE is the electric field number.
