Time-resolved measurements of electrohydrodynamic phenomena in an AC dielectric barrier discharge electrostatic precipitator

Résumé

In this paper, the interaction between a dielectric barrier discharge and submicron particles is investigated experimentally using Laser Doppler Velocimetry (LDV) and Particle Image Velocimetry (PIV) techniques in a 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 indicate that the particle time-averaged velocity increases with the HV frequency whatever the measurement position due to electric wind effect. The time-resolved velocity increases during both positive and negative discharges inducing a strongly non-stationary EHD flow. After the propagation of streamers, a reduction of the particle number in the gap is observed at low frequency due to particle charging and electrostatic precipitation by the electric field.
