摘　　要：本文采用CFD方法对反应堆整体水力试验均流板模型进行了详细的流场分析。计算获得的堆芯入口流量分配与试验结果相比，大部分组件的偏差在3％以内，个别组件的偏差在5％左右。说明本文的分析方法可用于反应堆反应堆以及后续堆型的堆内流场分析，具有广泛的工程应用价值。The flow field in the reactor model for hydraulic test based on even-flow distributor is an- alyzed by using CFD method in this paper. The core inlet flow distribution taken from CFD result is better than the one from hydraulic test. The deviations between CFD result and test are less than 3 percent for the most of fuel assemblies, and about 5 percent only for several ones. Therefore the method used in the paper is suitable for flow field analysis in reactors and it has a great application value in engineering.
