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.
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.
