Abstract

Plasma jets obtained at pulsed power facilities are considered. This is one of the most relevant areas of laboratory astrophysics, namely the study of astrophysical jets. The work is devoted to numerical simulation of plasma jets formed by a high-current vacuum arc discharge. Radiation magnetic gas dynamics models are applied. The use of wide-range equations of state and improved models of radiative energy transfer provided calculated results comparable with experimental data and evaluation of the similarity criteria of astrophysical and laboratory jets. Experiments with hydrogen jets, which best correspond to astrophysical prototypes, seem to be the most promising.

等离子体射流的辐射磁性气体动力学模拟

考虑了在脉冲动力装置中获得的等离子体射流。这是实验室天体物理学中最相关的领域之一，即对天体物理射流的研究。本文研究了大电流真空电弧放电等离子体射流的数值模拟。应用了辐射磁气动力学模型。使用宽范围状态方程和改进的辐射能量传递模型提供了与实验数据相当的计算结果，并评估了天体物理和实验室射流的相似准则。氢喷流的实验，最符合天体物理学的原型，似乎是最有希望的。
