| Outline of Final Research Achievements |
When two circular cylinders are set as the staggered arrangements in smooth flow, it is found that the fluid forces acting on the two cylinders or the vortex-induced vibrations of the cylinders are different due to spacing between the cylinders. A study of the vortex-induced vibrations of the cylinders were achieved due to spacing ratios of 2 and 3 between the cylinders.
In this study. we focused on the low Scruton number in order to achieve the computation for the vortex-induced vibrations of the close cylinders, so we could accurately obtain the numerical results even in such the low Scruton number.
