Time-resolved measurements of the electrohydrodynamic phenomena in an electrostatic precipitator using AC dielectric barrier discharges

Résumé

In this paper, the interaction between a dielectric barrier discharge and submicron particles is investigated experimentally using Laser Doppler Velocimetry (LDV) technique in wire-to-plane configuration. The induced electrohydrodynamic (EHD) phenomena have been studied by time-averaged and time-resolved measurements for different AC high voltage waveforms. The main results indicates that the particle time-averaged velocity increases with the HV frequency whatever the measurement position due to electric wind effect on particles. The time-resolved velocity increases during both positive and negative discharges inducing a strongly non-stationary EHD flow. After the propagation of a streamer, a reduction of the particle number in the measurement volume is observed at low frequency probably due to the pressure wave generated by the streamer.
