The Plasma Processes of Porous Dielectric Discharge based on Percolation Structure

Porous media have received increasing attention in plasma sterilization, all-solid-state battery technology, and surface functionalization of biological tissue materials. Due to their complex structure and discharge characteristics, which are difficult to simulate, the current research is still not deep enough. In this paper, we simulate a two-dimensional porous medium by using percolation structure to realize plasma discharge simulation. The results show that the simulation parameters of two-dimensional percolation model are similar to that of two-dimensional real porous slices, which can characterize physical properties of porous media well while greatly reducing the simulation computing time. In addition, we simulate this model at different porosity and pore size parameters. The conclusion shows regularity in Paschen curves. This study provides a new idea of simulation for theoretical analysis on porous media, improves the simulation efficiency at the same time. In addition, this new model is applied to reveal the discharge phenomenon of porous media under different porosity and pore size parameters.
