摘　　要：利用计算流体动力学(CFD)方法对带定位格架棒束内单相流体三维流场进行研究,以了解定位格架对流体流动的影响。用激光多普勒测速系统测量的实验数据对预测结果进行了校验,两者吻合较好。The 3-D flow field of rod bundles with spacer grids and the effects of grid structure on the flow are studied by numerical solution with computational fluid dynamics (CFD) method and laser Doppler velocimeter test. Velocity profiles from the CFX program were compared with laser Doppler velocimeter measurements taken from the flow field upstream and downstream of spacers in a full scale, cold water test loop. The results of the comparison show good agreement.
