S. R. Hudson, R. L. Dewar, M. J. Hole, M. McGann

摘要:

我们描述了一个磁流体动力学(MHD)约束的能量泛函平衡计算,结合了理想的MHD的泰勒松弛元素的拓扑约束。混沌状态允许部分混乱的磁场和非平凡的压力分布支持的一组离散的理想接口与非理性的旋转变换。数值解计算使用步进压力平衡代码,SPEC,基准和收敛计算。

英文摘要:

We describe a magnetohydrodynamic (MHD) constrained energy functional for equilibrium calculations that combines the topological constraints of ideal MHD with elements of Taylor relaxation. Extremizing states allow for partially chaotic magnetic fields and non-trivial pressure profiles supported by a discrete set of ideal interfaces with irrational rotational transforms. Numerical solutions are computed using the Stepped Pressure Equilibrium Code, SPEC, and benchmarks and convergence calculations are presented.
