摘要：

A two-dimensional numerical model was developed to investigate the problem of vortex induced vibration of a main circular cylinder with multiple small control rods by solving the Naiver-Stokes Equations at low Reynolds number. The numerical results show that the spacing ratio G / D has a significant effect on the kinematic response of the cylindrical system. Based on the vortex induced vibration response characteristics of the cylin-drical group, the effect of the gap ratio on the occurrence of vortex induced vibration in the cylindrical group can be divided into three intervals. And the numerical results also show that the vibration amplitude can be reduced obviously by using small control rods in the scope of present study.
