We present numerical simulation studies on the combined influence of a resonant magnetic perturbation (RMP) and a sheared toroidal flow on the characteristics of edge localized modes (ELMs). We find that the presence of a sheared flow enhances the stabilising effect of the RMP in a synergistic manner. For a fixed RMP power a comparative study is made of the nature of ELM dynamics for different flow configurations. A counter-current off-axis flow is found to be the most effective in mitigating ELMs by changing their nature from a spiky type-I kind of ELMS to a grassy variety. There is also a concomitant improvement in the over all plasma beta and energy confinement time.

我们对共振磁扰动 (RMP) 和剪切环流对边缘局部模式 (ELM) 特性的综合影响进行了数值模拟研究。我们发现剪切流的存在以协同方式增强了 RMP 的稳定作用。对于固定的 RMP 功率，对不同流动配置的 ELM 动力学性质进行了比较研究。发现逆流离轴流通过将 ELM 的性质从带刺的 I 型 ELMS 转变为草本植物，是减轻 ELM 的最有效方法。总血浆β和能量限制时间也有伴随的改善。
