Model Analysis of Self- and Laser-Triggered Electrical Breakdown of Liquid Water for Pulsed-Power Applications


Electrical breakdown simulations for liquids, in response to a submicrosecond (~100-200 ns) voltage pulse, are carried out. It is shown that breakdown is initiated by field emission at the interface of preexisting microbubbles. Impact ionization within the microbubble gas then contributes to plasma development, with cathode injection having a delayed and… (More)
