Abstract

Kinetic corrections to SOLPS-ITER fluid equations are made to extend their applicability for description of the neoclassical part of impurity transport to collisionless regimes of the main ions. Analysis is performed of impurity transport for the H-mode transport edge barrier and pedestal for several tokamaks: ASDEX-Upgrade, JET and ITER based on SOLPS-ITER modelling. Poloidal distribution of impurities and their radial fluxes are studied in detail. Significant difference of impurity drift flows with respect to neoclassical theory predictions is obtained for JET and ASDEX-Upgrade, while for ITER the drift flows reproduce neoclassical transport.

SOLPS-ITER在托卡马克基座区域杂质输运模拟中的修正

对SOLPS-ITER流体方程进行了动力学修正，以扩大其对描述杂质输运新经典部分的适用性，使其适用于主要离子的无碰撞状态。基于SOLPS-ITER模型，对ASDEX-Upgrade、JET和ITER等几个托卡马克的h模输运边缘垒和基座进行了杂质输运分析。详细研究了杂质的极向分布及其径向通量。JET和ASDEX-Upgrade的杂质漂移流与新古典理论预测有显著差异，而ITER的杂质漂移流再现了新古典输运。
