摘要
在Hall MHD方程组中引入外部驱动电流项,数值模拟驱动电流对双撕裂模不稳定性发展的影响.研究结果表明,外部驱动电流在撕裂模磁岛的x点要比在O点抑制效果好;在x点加入反向外部驱动电流对撕裂模的发展有抑制作用,周期性的外部驱动电流对双撕裂模不稳定性的抑制效果较好,在相同的模拟参数下,周期性的外部驱动电流加入越早对撕裂模的抑制效果越好.
Considering the external drive current in Hall MHD equations, the effects of external current drive on the instability of the double tearing mode are numerically investigated. The results show that the double tearing mode can be suppressed by the current drive, the current drive at the X-point of tearing mode magnetic islands is better than at the Opoint. Periodic external current drive has a good effect on stabilizing the double tearing mode, and the soon the better stabilizing effect.
