| 摘 要： | 将反应堆堆芯元件简化为圆柱排列,用涡格子CFD(计算流体力学)方法对其中基本并列双圆柱元素进行数值研究.利用这种方法直接计算出涡的对流和扩散,通过对流场中涡运动的物理机理的计算与描述,得到流体运动绕流双圆柱作用力的变化,揭示出堆芯元件的流致振动流体力学机理.

| Abstract: | In this paper,the vortex lattice CFD(Computational Fluid Dynamics)method is employed to investigate the dynamic response of core fuel and control rods on the fluid flow in nuclear reactors.The vor-tex lattice CFD method can represent the mechanism of flow-induced vibration through studying the vortex convention and vortex diffusion.Based on the computational results,compared with other published experi-mental and numerical data,the variation of magnitude and direction of the force is found to be the basic rea-son for flow induced vibration. |
