Simulation of the Discharge Regime Transition under Repetitive Nanosecond Pulses in Nitrogen at Atmospheric Pressure

In this paper, a two-dimensional particle model coupled with an external electrical circuit is proposed to study the evolution of the streamer dynamics under nanosecond repetitively pulsed discharges. Discharge regime transitions between corona, glow and spark regimes under single and repetitive nanosecond pulses are investigated. The dominating factors, such as charged particles accumulation and relaxation, are taken into consideration to give theoretical explanations.
