摘要：
The effect of resistivity on small edge localized mode (ELM) is investigated based on the peeling-ballooning three-field module of BOUT++. The ELM size increases with increasing resistivity, which is attributed to both linear growth rate and turbulence intensity. In the high resistivity case, a large linear growth rate causes a fierce initial collapse of pedestal, and the short duration of the zonal flow results in weak turbulence suppression, leading to more additional energy loss in the turbulence transport phase. This work is expected to provide some reference on understanding small ELM. Published by AIP Publishing.
