In the present study, a computational fluid dynamics (CFD) model coupling with a fluid-structure interaction (FSI) computational method is employed to perform two-degree-of-freedom (2-DOF) VIV simulations of shear flow past a circular cylinder with multiple control rods. The RANS equations and shear stress transport (SST) k-ω turbulence model are used to calculate the vortex field, while a fourthorder Runge-Kutta method is employed for evaluating the structure dynamics. The effect of the number of small rods, attack angle, diameter ratio and gap between the main and small cylinders are discussed in detail. It is found that placing a certain amount of small rods at appropriate locations can achieve good suppression effectiveness, but the effect is different at different diameter ratios or different gaps. Under a specific shear flow, a reasonable parameter combination is finally obtained to achieve the maximum suppression effectiveness in the present Re-range.
