This paper present a numerical study of vortex-induced vibration of four rigidly connected cylinders in a square arrangement in an oscillatory flow. The cylinders are elastically mounted and are only allowed to vibrate in the cross-flow direction. The gap between two neighbouring cylinders is 3D, where D is the cylinder diameter. The Reynolds number and Keulegan–Carpenter (KC) are kept at constants of 2 × 104 and 10, respectively. The reduced velocity is in the range of 1–15. The vibration amplitude and frequency are compared with those of a single cylinder. Two lock-in regimes of the reduced velocity are found to be the same as that of a single cylinder. Between the two lock-in regimes, the vibration amplitude is zero because of the symmetric vortex shedding flow pattern.
