文摘The edge transport code SOLPS5.0 is used to model edge plasmas in the experi- mental shots on JT-60U and the profiles of the transverse particle and heat transport coefficients D, Xe and Xi along the outer midplane are obtained by fitting the simulational results to the experimental data in L-mode shot 39090 and H-mode shots 37851, 37856. The modelling and fitting results show that within the pedestal region in H-mode shots 37851 and 37856 the radial particle transport coefficient D exhibits a significant drop, but, for L-mode shot 39090, the obvious drop in both D and Xe was not found.
文摘[目的]由于FORAN V70 R2.0(及以上版本)输出的JT模型中存在很多同名的特征节点,导致采用间隙分析软件对其进行分析时时间消耗加大且间隙分析结果难以处理。针对该问题,[方法]在研究FORAN导出的JT文件装配结构和蕴含信息(几何信息、材料属性信息等)的基础上,提出一种特征节点合并算法。该算法由坐标变换、模型节点更名、节点几何数据移动和材料属性处理4个步骤构成。然后,利用C++及JT Open Toolkit实现所提出的算法。[结果]结果显示,利用该算法处理后的JT模型只包含1个装配节点且保留了原始JT模型的内在信息,可为后期间隙分析提供有效的输入数据。[结论]大量的实例验证了所提出算法的有效性,处理后的JT文件大小可减少7%~20%。
