Abstract

![CDATA[Vortex induced vibration of a circular cylinder with multiple small-diameter control rods at a relatively low Reynolds number Re = 200 is numerically investigated in this study. The numerical model is based on the Reynolds-Averaged Navier-Stokes equations. The Arbitrary Lagrangian-Eulerian (ALE) method is employed to consider the motion of the circular cylinders. The Petrove Galerkin Finite Element Method (PG-FEM) is used to discretize the governing equations. The numerical results show that the maximum oscillation amplitude for the small gap ratio of G/D = 0.1 is almost the same as that of an isolated circular cylinder. However, for larger gap ratios, the maximum oscillation amplitudes are much smaller. Therefore, the VIV response of the circular cylinder can be successfully suppressed by the six control rods in present study.]]
