Abstract

Prebreakdown events in a nonuniform field in water were studied experimentally. Branching dendrites propagating with subsonic velocities and thin supersonic plasma channels were observed to form. It was found that, in deionized water, heating has no effect on the initiation and development of discharge channels. It is further shown that the EHD (electrohydrodynamic) events for discharge times of 10^-4 to 10^-3 affect the development of slow dendrites without changing the discharge dynamics
