Abstract

A new analytical model for the generation of axially symmetric jets (directed jets) in a nondissipative, nonequilibrium stratified plasma has been created in the magnetohydrodynamics approximation. The model is based on the assumption of Schwarzschild convective instability in plasma and on the condition that the magnetic field lines are frozen into matter. It is shown that jets with poloidal velocity and magnetic fields are generated in such a plasma. The dynamics of the velocity field and the magnetic field and the dynamics and structure of the arising toroidal electric current are studied.

等离子射流产生模型

摘要

在磁流体动力学近似中，已经创建了一种在非耗散，非平衡分层等离子体中产生轴对称射流（定向射流）的新分析模型。该模型基于等离子体中Schwarzschild对流不稳定性的假设以及磁场线冻结成物质的条件。结果表明，在这种等离子体中产生了具有极速和磁场的射流。研究了速度场和磁场的动力学以及所产生的环形电流的动力学和结构。
