How does plasma recycling affect fusion energy's edge dynamics? This research explores the impact of dynamic plasma recycling on transient edge plasma transport phenomena, particularly edge-localized modes (ELMs), using numerical simulations. By coupling the UEDGE and FACE codes within a realistic tokamak geometry, the study demonstrates that dynamic plasma recycling exhibits distinct characteristics on the main wall versus divertor plates. The simulations reveal that the outer wall can dynamically absorb and release particles comparable to those expelled by ELMs, exceeding the retention capacity of divertor surfaces. These findings provide crucial insights into the evolution of edge and divertor plasma conditions during an ELM cycle, contributing to a better understanding of plasma behavior in fusion reactors and aiding the development of more efficient fusion energy technologies.
