Abstract

The results of modeling a nanosecond discharge in a uniform electric field in argon at atmospheric pressure based on two kinetic models are compared: with one and with six excited states, respectively. The analysis of the development of ionization waves in a centimeter gap in a two-dimensional axisymmetric geometry is performed. It is shown that the obtained result is influenced by the choice of the transport cross-section of electron scattering on the argon atom. The electric field strengths, charged particle concentrations, and velocities of cathode- and anode-directed ionization waves at different time points are compared.

气体预电离条件下常压下氩气中纳秒放电的形成

摘要

比较了基于两种动力学模型在大气压下在氩气中均匀电场中纳秒级放电的建模结果：分别具有一个和六个激发态。对二维轴对称几何形状中厘米间隙中的电离波的发展进行了分析。结果表明，所获得的结果受氩原子上电子散射的传输截面的选择的影响。比较了不同时间点的电场强度，带电粒子浓度以及阴极和阳极定向电离波的速度。
