%X 钠冷快堆的自然循环过程是在低雷诺数条件下进行的，所以研究在低雷诺数条件下钠冷快堆的流动特性是非常有必要的。利用计算流体力学软件对钠冷快堆带绕丝棒束进行了数值模拟，结果表明，Rehme关系式与模拟的结果是吻合较好的。燃料组件的入口距离是小于一个螺距的距离，且出口效应对摩擦阻力系数影响不大。<br />
The natural cycle of sodium-cooled fast reactors is carried out under low Reynolds number conditions, so it is necessary to study the flow characteristics of sodium-cooled fast reactors under low Reynolds number conditions. The numerical simulation of the wire-wrapped rod bundle of the sodium-cooled fast reactor is carried out by using computational fluid dynamics software. The results show that the Rehme relationship is in good agreement with the simulation results. The inlet distance of the fuel assembly is less than a pitch, and the outlet effect has little effect on the friction resistance coefficient.
