摘要

摘要: 环形燃料具有两条冷却通道，外通道与内通道的冷却水流量分配比（φ）的变化可能会对芯块传热特性产生影响。本文建立了环形燃料单棒流固耦合CFD计算模型，在4种不同的流量分配比工况下，通过计算3个反映芯块传热特性的评价指标，研究了流量分配比变化对环形燃料芯块传热特性的影响。由分析计算结果可知，流量分配比变化不会对有间隙结构的环形燃料的芯块传热特性产生显著影响。

Abstract: Annular fuel has two coolant channels, and the change of coolant flow distribution ratio (φ) between external channel and internal channel may affect the heat transfer characteristics of the pellet. In this paper, a fluid-solid coupling CFD calculation model for single annular fuel rod was established. Under four different flow distribution ratio conditions, the influence of the change of flow distribution ratio on the heat transfer characteristics of annular fuel pellet was studied by calculating three evaluation indicators. The calculation results show that the change of flow distribution ratio has no significant impact on the pellet heat transfer characteristics of the annular fuel with a gap structure.
