Recent progress in experimental studies of electro-hydrodynamic flow in electrostatic precipitators

Abstract

Many experimental, theoretical and numerical works were devoted to the electrohydrodynamic (EHD) flow generated in electrostatic precipitators (EPSs). The generally accepted conclusion from these studies is that the EHD flow plays an important role in the particle collection in ESPs. However, despite of the recent fast progress in numerical simulation and experimental techniques used in the ESPs studies many problems related to the influence of the EHD flow on the performance of ESPs are unsolved. In particular, the influence of the turbulent EHD on submicron particles transport and deposition in ESPs is ambiguous. This problem and other related to the particle collection in ESPs are objectives of this paper, basing on the recent progress in experimental investigations of the EHD flow in ESPs. © Published under licence by IOP Publishing Ltd.
