摘　　要：采用计算流体力学软件CFX5.5和CFX4.4对中国先进研究堆(CARR)控制棒组件流场进行了数值模拟。计算区域分解成几个子区域,并在各子区域单独使用结构化和非结构化网格,解决了网格生成中遇到的难题。计算得出了控制棒组件的阻力特性,并根据计算结果对结构优化设计提出了改进意见。The computational fluid dynamics software CFX5.5 and CFX4.4 are applied to the three- dimensional flow field analysis of the Control Rod (CR) assembly of China Advanced Research Reactor (CARR). The calculating domain is parted into several sub-domains, and structured and unstructured grid are used separately in different sub-domain to solve the problem met in the process of grid building. The hydraulic resistance characteristic of CR is available. Some advices are given to optimize the structure of CR based on the calculation results.
