Fig. 5: Schematic diagram of the streamer evolution due to the gas flow.

From: Atmospheric diffuse plasma jet formation from positive-pseudo-streamer and negative pulseless glow discharges

Fig. 5

a The evolution of the positive streamer in the positive alternation. b The evolution of the negative streamer in the negative alternation. The vector vg means the gas flow velocity, the vector vi denotes the drift velocity of newly produced ions in the streamer channel, the vector E indicates the electric field.
