论文摘要
由于复杂的磁性3D几何形状，建模恒星的刮擦层是具有挑战性的。此处介绍的研究分析了使用EMC3- eirene代码进行磁标准配置的恒星Wendelstein 7-X（W7-X）的刮擦层（SOL）的模拟。与实验观测值相比，传输模型得到了验证。基于实验观察到的打击线宽度，用作代码输入的异常运输系数确定为$ 0.2 \ $ M $^2/$ s。但是，这与上游测量值分歧，在这种测量中，如此小的跨场传输导致的温度高于实验测量。
Modelling the scrape-off layer of a stellarator is challenging due to the complex magnetic 3D geometry. The here presented study analyses simulations of the scrape-off layer (SOL) of the stellarator Wendelstein 7-X (W7-X) using the EMC3-EIRENE code for the magnetic standard configuration. Comparing with experimental observations, the transport model is validated. Based on the experimentally observed strike line width, the anomalous transport coefficients, used as input to the code are determined to around $0.2\,$m$^2/$s. This is however in disagreement with upstream measurements, where such small cross-field transport leads to temperatures higher than measured experimentally.
