摘要:

利用化学动力学自洽解和自由电子的Boltzmann方程,研究了纳秒大气压氮气放电中电子能量分布函数的形成。放电后阶段被跟踪到几微秒。该模型是制定,以调查的截面集的作用,专注于通过共振通道的电子碰撞的振动激发。四个不同的截面集被认为是,一个基于内部一致的振动激励计算扩展到整个振动阶梯,和其他人通过应用常用的缩放定律。

英文摘要:

The formation of the electron energy distribution function in nanosecond atmospheric nitrogen discharges is investigated by means of self-consistent solution of the chemical kinetics and the Boltzmann equation for free electrons. The post-discharge phase is followed to few microseconds. The model is formulated in order to investigate the role of the cross section set, focusing on the vibrational-excitation by electron-impact through resonant channel. Four different cross section sets are considered, one based on internally consistent vibrational-excitation calculations which extend to the whole vibrational ladder, and the others obtained by applying commonly used scaling-laws.
