Analysis of particle trajectory in nanosecond pulsed DBD-ESP using time-resolved particle image velocimetry

Overview & Synopsis

In this paper, the interaction between nanosecond pulsed dielectric barrier discharge and submicron particles is investigated experimentally using particle image velocimetry technique in a wire-to-plane electrostatic precipitator. The induced electrohydrodynamic phenomena have been studied by using time-resolved measurements for both positive and negative polarities of the nanosecond pulsed high voltage. The main results indicate that the velocity of particles is considerably affected by the negative discharges related to the negative transition of the voltage pulse, whatever the polarity. This is probably due to the contribution of the electric wind that could affect both the trajectories of charged and uncharged particles.
