大气压氦气介质阻挡柱状放电2维仿真算法
Algorithms of 2D Simulation for Dielectric Barrier Columnar Discharges in Atmospheric Helium
摘要
Abstract
In order to investigate the influences of the finite element method (FEM), finite volume method (FVM), and the grid structures on the simulation of dielectric barrier columnar discharges in atmospheric helium, we established a twodimensional(2D) fluid model.Firstly, we calculated the current waveforms and 2D electron density distributions of the discharge;secondly, we comparatively studied the performances of the FEM and the FVM based on convergence plots, number of iterations, and computation time;finally, we comparatively studied discharge morphology and sequence obtained by the two algorithms based on the 2D electron density distributions and the experimental results.The results show that the discharge evolves from a uniform pattern into a columnar one in the unstable initial stage, and it reaches a steady colunmar discharge at last.The FVM is more stable and less time consuming than the FEM.And the variation of grid structure affects the discharge morphology obtained by the FVM.Under the square grid structure, the columnar discharge obtained by the FVM coincides with the experimental results.关键词
