The flow around cylinder has been extensively investigated because of its wide applications in civil engineering, such as offshore structures, tall towers or stacks or nuclear reactors. The high velocity fluid flow interaction with structural components can induces self-excited vibrations of the components. The fluidelastic instability can lead to the maintenance and operational problems. In order to analyzed flow induced vibration two-dimensional and three-dimensional Finite Element Models have been developed using commercial software. Comparison of numerical and analytical results have been done.
