Abstract
This paper concentrated on the morphology evolution, intermittent illuminance and branching of bushy streamers under various applied voltages. Experimental results showed that the evolution of streamer morphology was closely related with discharge energy. The shadow area of streamers rapidly grew with an increase in the applied voltage and streamers gradually evolve from the double-branch to multi-branch structure. The intermittent illuminance of streamer was observed and the average interval of illuminance decreased remarkably with the rise of applied voltages. This phenomenon is strongly affected by the deposition and dissipation of charges at gas/liquid surface of streamers. Streamer branching was determined by the uneven distribution of deposited charges and electrostatic force at gas/liquid surface. The experimental observation and theoretical calculations show that the protrusions and branching at channel surface become more apparent when streamers own smaller radii and grow rapidly with the rise of applied electric field.
