“…The phenomenon of two streamers in ns SDBD has been widely reported by many groups [14][15][16][17]. It is agreed that under a pulsed voltage with a fast ns rising and falling edge, the primary discharge with streamer-like morphology and the secondary discharge with diffused morphology will appear at the rising regime and decaying phase of the pulsed voltage, respectively [15,16]. However, as the rise time changes, some of the discharge characteristics may change, such as discharge ignition, plasma uniformity, thrust and so on [9,18,19].…”

Nanosecond pulsed surface dielectric barrier discharge (SDBD) is a hot topic in many fields, but the mechanisms of discharge evolution and micro-channel propagation are still not clearly understood. In this paper, a plasma fluid model of nanosecond pulsed SDBD is established, and the deductions of the two current spikes are verified and improved by simulation. The two current spikes correspond to the two stages of the discharge: the ionization wave propagation and the repeated re-ignition in the gap between the ionization wave and the dielectric surface. In the first stage, the ionization wave develops rapidly at first and propagates very slowly in the end, which produces the first current spike with a very short rise time and a tailing falling edge. The curve profile of the ionization wave velocity is very similar to that of the first current spike. A certain distance is maintained between the bottom of the ionization wave and the dielectric surface in this stage, which forms the gap for the next stage. In the second stage, the charged particle cloud induced by the quasi-uniform electric field in the middle of the gap and the new micro-channel from the edge of the high-voltage electrode propagate at first, and then merge together to establish a new discharge channel. The reverse electric field in the gap induced by the accumulated charges on the dielectric surface restricts the expansion velocity of the second discharge channel, which results in a longer rise time and falling time of the second current spike.

“…It is known that the secondary streamer propagates along the residual streamer channel after the propagation of the primary streamer. [39] The primary streamer is reinforced by the magnetic field, and thus more spatial charges can be retained in the streamer channels. As a result, in addition to the influence of the magnetic field, the increase of residual charges in the streamer channel may also promote electron avalanche and intensify the secondary streamer propagation process, resulting in a higher propagation velocity of the secondary streamer.…”

In this study, a magnetic field perpendicular to the electric field is introduced to the gear-cylinder dielectric barrier discharge (DBD) to enhance the plasma density and improve the volatile organic compounds removal performance at atmospheric pressure. Higher discharge intensity, enlarged plasma streamers region, and better toluene removal performance are obtained after introducing a 0.2 T magnetic field

“…11,12) When the head of the primary streamer reaches the counter electrode, the electric field is distributed in the electrode gap again and secondary streamer occurs. 15) The transition from primary to secondary streamer induces a reduction in the reduced electric field and heating of the gas molecules and causes a decrease in energy efficiency. It is also significantly affected by the transition to spark discharge in the later phase.…”

A compact and lightweight gas treatment system integrated with a high-voltage pulse generator driven by SiC-MOSFET and wires-to-wires electrode. The maximum amplitude and pulse width of the output voltage of the pulse generator without load are 10 kV and 31 ns, respectively, and the maximum energy transfer efficiency reaches 88% with a load resistance of 0.44 k. This pulse generator was applied to a multilayered wires-to-wires electrodes and the streamer discharges propagate between the electrodes was observed. Streamers initially propagates horizontally according to the Laplacian electric field near the high-voltage electrode. When they approach the ground electrodes, they curve and propagate toward the ground electrode due to the high electric field between the streamer head and the ground electrode. The velocity of the streamer propagation is with a velocity of 0.4 to 0.71 × 106 m/s. Ozone production and ethylene removal characteristics are investigated in a sealed vessel.
