使用平均场欧姆定律开发了大规模磁场演化的数值模拟。将欧姆定律与 Δ’ 稳定性分析和磁岛生长方程相结合，以模拟受撕裂模式影响的托卡马克等离子体的行为。在一组计算中，通过构建 li-qa 图来检查托卡马克的磁流体动力学 (MHD) 稳定状态。结果证实了之前的计算结果，即撕裂模式在 li-qa 空间中引入了稳定边界。在另一系列的模拟中，研究了撕裂模式和自举电流之间的相互作用。结果表明，即使没有任何外部施加的环路电压或电流驱动，完全自举的托卡马克也是可能的。
Numerical simulations of the evolution of large‐scale magnetic fields have been developed using a mean‐field Ohm’s law. The Ohm’s law is coupled to a Δ’ stabilty analysis and a magnetic island growth equation in order to simulate the behavior of tokamak plasmas that are subject to tearing modes. In one set of calculations, the magnetohydrodynamic (MHD)‐stable regime of the tokamak is examined via the construction of an li ‐qa diagram. The results confirm previous calculations that show that tearing modes introduce a stability boundary into the li ‐qa space. In another series of simulations, the interaction between tearing modes and the bootstrap current is investigated. The results indicate that a completely bootstrapped tokamak may be possible, even in the absence of any externally applied loop voltage or current drive.
