高度电离非等温等离子体中的schock波真的存在吗?

Does the schock wave in a highly ionized non-isothermal plasma really exist ?

摘要:

本文研究了高气压气体中的高电离激波的结构。我们考虑到气体电离时,气体温度达到电离势的几个订单。结果表明,在气动升温激波作用下,形成高度电离的非等温等离子体$T_e>>T_i$后,只有孤立的离子-声波(孤子)能在该等离子体中传播。在这样的波中发生电荷分离:电子和离子形成具有电场的双电层。得到了冲击波的波形、振幅和波阵面宽度。

英文摘要:

Here we study the structure of a highly ionizing shock wave in a gas of high atmospheric pressure. We take into account the gas ionization when the gas temperature reaches few orders of an ionization potential. It is shown that after gasdynamic temperature-raising shock and formation of a highly-ionized nonisothermal plasma $T_e>>T_i$ only the solitary ion-sound wave (soliton) can propagate in this plasma. In such a wave the charge separation occurs: electrons and ions form the double electric layer with the electric field. The shock wave form, its amplitude and front width are obtained.
