FLOW-INDUCED VIBRATIONS OF TWO TANDEM CYLINDERS IN A CHANNEL

Abstract

We numerically studied flow-induced vibrations of two tandem cylinders in transverse irection between two parallel walls. The effect of the horizontal separation etween two cylinders, ranging from 1.1 to 10, on the motions of the cylinders and he flow structures were investigated and a variety of periodic and non-periodic vibration egimes were observed. The results show that when two cylinders are laced in close proximity to each other, compared with the case of an isolated cylinder, he gap flow plays an important role. As the separation ratio is increased, he fluid-structure interaction decouples and the cylinders behave as two isolated ylinders.
