摘要:The deepwater riser may experience vortex-induced vibration (VIV) as exerted by the flows in the sea. The fluid excitation of a flexible pipe results in modal vibrations. To solve the fluid-structure interaction problem of vortex-induced vibration of bluff bodies at high Reynolds number in a range of natural frequencies and damping ratios, the strip theory approach will be taken into this study, and the discrete vortex method (DVM) is used to calculate the vortex-induced vibration of each strip, while the finite volume method (FVM) is employed for evaluating the structure dynamics of a 3D deepwater riser.
