Multiphysics simulation of the initial stage of plasma discharge formation in liquids

Plasma initiation simulations in homogenous liquids in response to ∼3.0–5.0 ns voltage pulse is conducted. An in-house numerical framework consisting of a compressible fluid solver together with charged species conservation and Poisson's equation solver is employed for the simulations. The simulations are conducted for a needle-like powered electrode with two different voltage profiles—linear and exponential increase. The model predictions show...
