CFD simulation of long slender offshore structures at high Reynolds number

Slender cylindrical structures are common in many offshore engineering applications such as floating wind turbines and subsea risers. These structures are vulnerable to flow-induced vibrations under certain environmental conditions which impacts their useful life. Flow-induced vibrations have been widely studied both experimentally and numerically especially at low Reynolds number. However, many questions remain unanswered in detail regarding the effects of high Re on structural responses and fluid-structure interaction (FSI) phenomena such as lock-in for different design configurations. Furthermore, under realistic environmental conditions, the oncoming flow velocity profile may not be uniform. In such scenarios, effects of large changes in Re along span on nature of structural responses may be significant.
