An electron diffusion model of the space-time distribution of radicals in a multibubble cavitation field
Tóm tắt
Conditions under which electric discharges can arise in cavitation bubbles pulsating in a multibubble cavitation field are considered. Possible electric discharge types are discussed. It is shown that, in an electric breakdown in a cavitation bubble, the probability of the formation of a streamer (all the more, a leader) or corona discharge is negligibly small. It was found that, in a cavitation bubble, the development of an electron avalanche is most probable. The basic parameters of an elementary electron avalanche are estimated.
