摘要： 冷却管是遍布聚变反应堆的重要部件,其对聚变堆的核安全有重要影响,研究冷却管的可视化对改进聚变核安全有重要意义。因为冷却管呈线性分布,所以基于管道中心线进行可视化是常用方法,但从复杂冷却管的面片模型中提取中心线非常繁琐。针对这个问题,提出了一种解决方法,首先使用平均曲率流算法提取中心线附近的离散点,然后设计了一种优化方法,基于管道段是圆柱或圆环及管道段之间的连接关系这个先验知识,从离散点构建准确的中心线段,包括中心线段的类型、方程及中心线段之间的连接关系。使用国际热核聚变实验堆(International Thermonuclear Experimental Reactor,ITER)的冷却管验证所提方法的有效性,实验结果表明,所提取管道中心线符合要求,能有效支持后续可视化任务,证明了所提方法是有效的。
