Abstract

Injection of plasma flow generated by a quasi-stationary plasma accelerator into a region with a magnetic field created by a series of ring current-carrying conductors forming a solenoid is considered. Numerical studies are carried out based on the set of magnetogasdynamic (MGD) equations represented in terms of the vector potential of the magnetic field, taking into account electrical conductivity, thermal conductivity, and radiation transport, provided that the plasma accelerator and ring conductors are located on the same axis. It is shown that small currents in ring conductors create a magnetic field inside the solenoid, which does not significantly affect the main stream, while simultaneously isolating it from the current coils as a result of the formation of a rarefied plasma layer separating the high-speed flow of dense plasma. Calculations of the MGD problem also show that the plasma flow within the solenoid is not accompanied by an increase in the temperature of the medium.

电磁场中等离子体流注入的数值模型

摘要

考虑将由准静态等离子体加速器产生的等离子体流注入具有由形成螺线管的一系列环载流导体产生的磁场的区域中。基于等离子体场加速器和环形导体的电导率，热导率和辐射传输，基于以磁场矢量势表示的一组磁气动力学（MGD）方程组进行了数值研究在同一轴上。结果表明，环形导体中的小电流会在螺线管内部产生磁场，该磁场不会显着影响主流，同时由于形成了将高速分离的稀疏等离子体层而将其与电流线圈隔离密集的血浆流。
