摘要: 在静电磁流体方程基础上提出了柱状放电电弧等离子体的磁螺旋不稳定性的一种新的线性分析方法。通过数量级分析得到了简化扰动能量方程。数值研究了外加轴向磁场、输入功率和弧柱半径外管壁半径相对大小等对电弧不稳定性的影响
关键词: 电弧等离子体, 磁流体方程, 螺旋不稳定性
Abstract: A new linear analysis for magnetic helical instabilities of arc discharges in a cylindrical plasma is deve-loped based on a set of electrostatic magnetohydrodynamic(MHD) equations.By the correct electrostatic ordering the perturbed energy equations are simplified.The effects of the external axial magnetic field,the arc currents and the relative rates of arc column radius on the arc helical instabilities are studied by numerical method.
Key words: arc plasma, MHD equation, helical instabilities
