| 摘 要： | 基于磁流体理论利用CIP方法数值对电阻磁流体中的磁岛演化动力学行为进行了长时间模拟。研究发现,磁岛饱和后流体演化并未结束,磁场重联将导致流体的宏观剪切流动。这一物理图象可用于解释托卡马克等离子体L-H模转换过程中观察到的磁流体行为。

| Abstract: | Employing the CIP method for the numerical simulation, the behavior of the magnetic island evolution in the resistive magnetic fluid was simulated for long time based on the theory of magnetic fluid. It is found that fluid evolution after magnetic island saturation has not ended yet, magnetic reconnection will lead to a macroscopic shear flow. This physical picture can be used to explain the magnetic fluid behavior observed during the tokamak plasma L-H mode transition. |
