Local mean velocity and turbulence intensity measurements were obtained with DANTEC 55 X two-dimensional Laser Dopper Anemometry (LDA) for rod bundle of reactor fuel assembly test model whick was a 4x4 rod bundle.

• 采用DANTEC 55X两维激光多普勒测速仪对反应堆燃料组件棒束流场进行了测试,获得了其不同断面处的紊流速度分布及湍流特性,并进行了理论模型计算分析,试验结果与理论计算及他人实验结果符合较好。
