Numerical Analysis of the Plasma Characteristics of Pulsed Discharge in Water

Channel characteristics of the cylindrical geometry of the plasma pulsed discharge were described by conservation equations of energy,momentum and mass.The 4th-order Rounge-Kutta method was employed to solve for the time-variation responses such as the current,the temperature,the channel radius and the particle density and pressure,and also interrelationship between them.The purpose of this paper was to provide the reference for further studying the chemical and physical effects of the pulsed discharge plasma.
