摘要

给出了在分离电子和离子温度的双温气体动力学模型中等离子体射流向稀薄介质膨胀的数值模拟结果。将两种独立的数值方法得到的结果与室内真空室喷射实验数据进行了比较。结果表明，射流主体质量的离子和电子温度处于平衡状态。考虑到发电机喷嘴的变形，给出了喷射情景的估计。

Numerical Simulation of Plasma Jet Expansion in a Laboratory Experiment

The results of numerical simulation of plasma jet expansion into a rarefied medium in a two-temperature gas dynamics model with separation of electron and ion temperatures are presented. The results obtained using two independent numerical methods are compared with the data of a laboratory experiment on jet injection into a vacuum chamber. It is shown that the ion and electron temperature of the main mass of the jet is in equilibrium. Estimates of the injection scenario are given taking into account the deformation of the generator nozzle.

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.
