英文摘要A BOUT++ three-field MHD model is applied to study the effect of the pedestal pressure profile modified by the pellet injection from the low field side on the nonlinear behaviors of ELM. The linear simulation shows that the growth rates of all toroidal modes can be enhanced regardless of the deposition location and are more affected by the pellet atoms depositing in the steep pedestal region. From the nonlinear simulation, a threshold behavior for influencing the natural ELM by the ablated pellet in terms of the rate of the modified pressure over the unperturbed one at the most affected position (R-p = P-mod,P-MAP/P-0,P-MAP) is demonstrated when the pellet deposits its atoms on the pedestal top. In contrast, when the pellet deposits its atoms within the steep pedestal region, the ELM size is increased at low and high R-p but decreased in an intermediate range. This result can perhaps explain the probabilistic behavior of ELM triggering by small pellet injection on EAST observed in previous experimental results.
