Abstract
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.
