为研究堆芯组件安装方式对组件间流量分配的影响，通过CFD数值模拟软件 FLUENT ，对中国实验快堆（CEFR）1型小栅板联箱上的7盒组件在22种安装情况下进行三维数值模拟。由计算结果可知，组件在22种布置情况下的流量与设计值的相对偏差为0.41％～2.03％。根据计算结果可更准确地预测堆内最热管的流量分配，可为今后CEFR的组件安装方式提供参考。

In order to study impact of the core assembly installation on flow rate distri‐bution among core assemblies ,three‐dimensional numerical simulation was carried out with CFD code FLUENT to investigate the flow rate distribution of 7 assemblies installed on China Experimental Fast Reactor (CEFR) type‐1 distribution header .The calculation results show that the relative deviations of calculated flow rates and their design values under 22 kinds of assembly arrangements are 0.41%‐2.03% .Not only the flow distribution in the hottest tube can be more accurately determined ,but also the reference for the assembly installation in CEFR is figured out according to simulation results .
