论文摘要
New Grad's-Zhdanov模块在SOLPS-ITER代码中实现，并应用于ITER杂质传输模拟。由于改善的平行动力学系数，氦转运中出现了显着差异。结果，对于恒定的氦源和泵送速度，观察到分离质平均相对浓度的30 \％降低。讨论了杂质行为的改变。因为霓虹灯的变化不太明显。首次在ITER刮擦层条件下首次研究离子分布函数，以揭示动力系数改进和理论局限性的起源。
New Grad's-Zhdanov module is implemented in the SOLPS-ITER code and applied to ITER impurity transport simulations. Significant difference appears in the helium transport due to improved parallel kinetic coefficients. As a result 30\% decrease of the separatrix-averaged helium relative concentration is observed for the constant helium source and pumping speed. Change of the impurity behaviour is discussed. For the neon changes are less pronounced. For the first time the ion distribution functions are studied in the ITER Scrape-off layer conditions to reveal the origin of the kinetic coefficient improvements and theory limitations.
