Abstract
Vortex-induced vibration (VIV) of a circular cylinder at a low mass ratio of 1.5 between two lateral walls is investigated numerically. The focus of the study is to examine the effects of the two lateral walls on the VIV. Numerical simulations are carried out for w/D = 4, 6, 10, and 20 with D and w being the cylinder diameter and the distance between the two walls, respectively. It is found that the effects of the two walls on the VIV are obvious as w/D <= 6 and negligibly small as w/D = 10. The VIV amplitudes in both x- and y-directions increase with the increasing w/D in the lock-in regime.
