d="p0005">A successful structural mechanism was designed and built to investigate the Wake Induced Vibration (WIV) response of the cylinder.

d="p0010">With staggered arrangement of the cylinders, the WIV responses can occur at frequencies outside the range in which Vortex Induced Vibration (VIV) is observed.

d="p0015">The staggered arrangement of the cylinders results in increased WIV efficiency as compared to the aligned arrangement of the cylinders.

d="p0020">The alteration of the Reynolds number changes the upstream vortex shedding frequency which affects the WIV efficiency.
