Chaos evolution of short-gap discharge under dielectric-covered electrodes

In this paper, the short gap discharge of electrode coverage was simulated numerically. The one dimensional and self-consistent fluid model of gas discharge was established which is composed by the electron and ion continuity and momentum transfer equations, and the nonlinear equations were solved by using the SG algorithm. The results showed that the short gap discharge of electrode coverage behaves the typical nonlinear characteristic such as Hopf bifurcation and Chaos. Two ways leading to Chaos have been found by changing discharge conditions, one is quasi-period and the other is double-period. Seemingly random discharge may reveal the hidden simple laws, through studying nonlinear phenomena of the short gap discharge of electrode coverage, especially the phenomena of Chaos to find out the common law, which is generally followed by complex issues.
