By scanning toroidal rotation with a combination of co- and counter-current direction neutral beam injection (NBI) on the Experimental Advanced Superconducting Tokamak, it is found the size of edge localized mode (ELM) decreases with increasing toroidal rotation in counter-current direction. The synergistic effect of plasma rotation and collisionality on ELM behavior is also studied by statistical analysis. Three-field module in BOUT++ framework is employed to study the impacts of toroidal rotation/E B flow shear on ELM behaviors. The BOUT++ simulation results show that both Co- and Ctr-NBI induced net flow have stabilization effects on the peeling-ballooning modes, especially for counter NBI case, high-n ballooning mode can be totally stabilized. With larger E B shear, the mode number of most unstable mode downshifts in the counter NBI case, with larger E B shear, the mode number of most downshifts in the counter NBI case, correlated with reduced ELM size.

通过在实验高级超导托卡马克上结合顺流和逆流方向中性束注入 (NBI) 扫描环形旋转，发现边缘局部模式 (ELM) 的大小随着逆流方向上的环形旋转的增加而减小. 还通过统计分析研究了等离子体旋转和碰撞对 ELM 行为的协同效应。BOUT++ 框架中的三场模块被用来研究环形旋转/ E B流剪切对 ELM 行为的影响。BOUT++模拟结果表明，Co-和Ctr-NBI诱导的净流对剥离-气球模态都有稳定作用，特别是在反NBI情况下，高-n气球模态可以完全稳定。与较大E B剪切，在反向 NBI 情况下最不稳定模式降档的模式数，具有较大的E B剪切，在反向 NBI 情况下大多数降档的模式数，与减小的 ELM 尺寸相关。
