Abstract
In this study, three-dimensional numerical simulations are performed to study the VIV of two side-by-side cylinders of different diameters in a steady flow. The two cylinders are rigidly connected together and elastically mounted as a single body. The main aim of the study is to identify the difference between the response of the two cylinder system and that of a single cylinder. It was found that the lock-in range of the reduced velocity of the two cylinder system is similar to that of a single cylinder. However, if the sum of the two cylinder diameter is used as the representative dimension of the system to calculate the reduced velocity, the lock-in regime is narrower that of a single cylinder.
