Simulation of gas discharge based on fractal theory

A flat-plate and pin-plate electrode gas discharge model based on fractal theory has been established in this paper. And to show the influence of the variation of electric field on the discharge routine development, the whole gas discharge process has been simulated and quantificationally analyzed. Moreover, the combination effect of the electric field and the random consideration on the discharge has been investigated. And the whole spatio-temporal evolvement behavior of the gas discharge path is computed using finite element method (FEM) and figured out. From the simulation results, it can be found that, the micro-discharge-channels have the tendency of being in the whole discharge space. And the discharge development routine is mainly determined by the electric field and the material diversity of the dielectric medium.
