摘要：Impacts of particle and energy fluxes during edge localized modes (ELMs) on the divertor targets were particularly studied through Langmuir Probes in EAST (Wang et al., 2012); however, no attempt has been made to model the time-dependent ELMy H-mode of EAST yet by the edge plasma code package SOLPS. This paper aims to model the type-III ELMy H-mode discharge in EAST using SOLPS. Firstly, we adjust the perpendicular anomalous transport coefficients (PATCs) by matching the experimental upstream radial electron density and temperature profiles under given type-III ELMy H-mode discharge conditions (shot #33266) to obtain the steady-state H-mode, and then, ELMs are modeled by periodically enhancing PATCs with the parameters, such as the repetition frequency and the energy expelled from the core plasma, taken directly from the experimental data of the given EAST discharge. In this way, many experimentally inaccessible upstream parameters can be evaluated through the simulation; meanwhile, many input parameters can be provided from such simulations to other codes for understanding the damage of plasma-facing materials caused by plasma irradiation.
