Abstract

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.
