| 摘 要： | 针对燃料组件滞留转运通道期间的自然循环传热过程开展了试验研究。获得了承载器顶角区域加热棒的试验数据，并拟合出传热经验关系式。计算结果与试验结果比较表明，该关系式能较好地计算顶角区域加热棒顶部局部努塞尔数Nu。并通过试验数据证实了在相同的燃料棒热流密度和承载器进口水温条件下，最靠近承载器顶角位置的1号棒的传热能力最差，壁温最高。

| Abstract: | The experiment was carried out to study the natural convection heat transfer of fuel assembly stayed in the transfer tube. The experiment data of the heating rods in the top corner of the carrier were obtained, and the correlations of heat transfer were proposed. The comparison between the calculated results and the experimental results show that the correlations can be used to calculate the local Nusselt number at the top corner of the heating rod. And it is varified that the heat transfer capacity of the No. 1 rod closest to the top corner of the carrier is the worst and the wall temperature is the highest under the same heat flux and inlet water temperature. |
