| 摘 要： | 采用计算流体动力学方法，通过对ITER 装置的设计结构进行合理简化，建立了ITER 装置的三维计算模型，研究了失真空事故下铍灰尘在ITER 装置内的迁移进程，得到了铍灰尘在ITER 装置内的分布情况。通过分析铍灰尘在不同截面高度、不同时刻的分布特性，得到以下结论：随着高度增加，截面位置上的铍灰尘体积分数呈下降趋势；随着时间推移，截面位置上的铍灰尘体积分数呈上升趋势。

| Abstract: | The three-dimensional numerical model of ITER, where the design structure was reasonably simplified, was built by computational fluid dynamics (CFD) method. The migration process of dust composed of beryllium in ITER during a LOVA was reproduced. The dust distributions at different heights and moments were analyzed. And it was found that the volume fraction of beryllium dust had a downward trend as the height increases and that the volume fraction of beryllium dust has an upward trend as time went. |
