摘要

这项工作探讨了在不同中心线积分密度 nli 值下，ITER Q = 10 基准等离子体方案当前升温期间的限幅器-分流器转换（L-D）。该分析基于使用最新版 SoleEdge-HDG 进行的传输模拟，重点关注热量和离子粒子通量的时间演变，揭示了内壁和面向等离子体组件 (PFC) 上温度升高的区域，尽管负载适中。研究还深入探讨了垂直对流通量项对密度积累的影响，比较了不同的配方及其与辅助加热源的相互作用。此外，论文还展示了在热核实验堆稳态情景下，考虑平行中性动量的演变对目标处等离子体和中性密度的影响。

First integrated core-edge fluid simulation of ITER’s Limiter–Divertor transition with SolEdge-HDG

This work explores the Limiter–Divertor transition (L–D) during the current ramp-up of ITER’s Q = 10 baseline plasma scenario at various central line-integrated density

values. The analysis, based on transport simulations performed with the latest version of SoleEdge-HDG, focuses on the time evolution of heat and ion particle fluxes, revealing regions of elevated temperature on the inner wall and plasma-facing components (PFCs) despite moderate loads. The investigation also delves into the effects of perpendicular convection flux terms on density build-up, comparing different formulations and their interplay with auxiliary heating sources. Furthermore, the paper shows the impact of taking into account the evolution of the parallel neutral momentum on plasma and neutral density at the targets in the context of an ITER steady-state scenario.
