本文将等离子体电流准均匀分布情况下任意截面轴对称环形位形的磁流体平衡解表示成多顼式,推导了椭圆磁轴邻域截面的倾斜和变形公式,计算了圆、椭圆、D 形和几种双流器位形在磁轴邻域的局部模稳定性条件。计算结果表明,D 形和合适的双流器位形有较好的局部模稳定性。
In this paper, the equilibrium solution of the magnetorheological fluid with axisymmetric annular configuration of arbitrary cross section under the condition of quasi-uniform plasma current distribution is expressed as a multi-angle equation. The formulas for the inclination and deformation of the elliptical magnetic axis in the cross section are deduced, and the circle, ellipse, And several kinds of double-flow device in the vicinity of the magnetic axis of the local stability of the mold conditions. The calculation results show that the D-shape and the suitable double-flow device shape have good local mode stability.
