Abstract
![CDATA[Vortex-induced vibration (VIV) of two elastically coupled side-by-side circular cylinders in steady flow at a low Reynolds number of 150 and mass ratio of 2 is investigated numerically. The focus of the study is to investigate the influence of the interference between the two circular cylinders on the response amplitude and frequency. The VIVs of both cylinders are confined in the cross-flow direction only. Simulations are carried out for the reduced velocities ranging from 1 to 30 to ensure that the whole lock-in regime is covered. The vibration of the two cylinders may lock-in with one of the two natural frequencies, depending on the reduced velocity. It is found that the lockregimes of the two natural frequencies overlap, forming a wider lock-in regime that is wider than that of a single cylinder. The response amplitude reaches it maximum when the vibration frequency is close to either the first mode or the second mode natural frequency.]]
