Abstract

The article presents the results of a 3D numerical simulation of the dynamics of high-speed aluminum plasma jets during their injection into a highly rarefied Earth’s ionosphere, which can be considered a vacuum. The standard hydrodynamic approach is modified for taking into account the regime of supersonic injection of plasma into a vacuum. Scenarios of single and opposite injections are considered. The gas-dynamic parameters of plasma formations and their optical characteristics, obtained using standard and modified approaches, are determined.

将高速等离子体射流注入真空的数值模拟

摘要本文介绍了高速铝等离子体射流注入高度稀薄的地球电离层（可视为真空）过程中的三维数值模拟结果。为了考虑等离子体超音速注入真空的情况，对标准流体力学方法进行了修改。考虑了单一注入和相反注入的情况。确定了等离子体形成的气体动力参数及其光学特性，这些参数是利用标准方法和修正方法获得的。

期刊介绍： Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
