Abstract
- The propagation features of a streamer discharge in water have been investigated. based on the experimental data obtained in the study of water discharges in a non-uniform electric field, the propagation of streamers is explained as the evaporation of water at the tip of the streamer and around it. The energy balance in the process of the streamer propagation is calculated for a sub-microsecond discharge in distilled water It is shown that the energy released in the prebreakdown process is sufficient to evaporate the liquid in the streamer channels. Similar velocity of the streamer propagation in both tap and distilled water substantiates negligible effect of ionic current density onto the streamer propagation process. These estimations based on the experiment have relevance to the discussion on the nature of the dielectric breakdown of water.
