Investigation of vortex-induced vibration phenomenon in verticallong circular slender structure with non-uniform flows
Analyzing the vortex-induced vibration of a slender marine structure withlength to diameter ratio up to 200 is the objective of this study. This slender is free to move in both in-line and cross flow directions and immersed completely in water. Three different types of shear currents pass on it and cause to vibrate slender in different forms. Nowadays, these vibrations are very important for de...
متن کاملa numerical model of vortex-induced vibration on marine risers
the steger and warming flux vector splitting implicit scheme is used to numerically solve two dimensional reynolds averaged navier–stokes (rans) equations governing the vortex induced vibration of a flexible riser laterally supported by a spring and a damper. the k–ε model is used as turbulence model to simulate the turbulent flow in the wake of the riser. to update the new position of the rise...
متن کاملGeneralized thick strip modelling for vortex-induced vibration of long flexible cylinders
Submitted for the DFD15 Meeting of The American Physical Society Generalized “thick” strip modelling for vortex-induced vibration of long flexible cylinders1 YAN BAO, RAFAEL PALOCIOS, SPENCER SHERWIN, Imperial College London, NEKTAR++ COLLABORATION — We propose a generalized strip modelling method that is computationally efficient for the VIV prediction of long flexible cylinders in three-dimen...
متن کاملModelling vortex-induced fluid-structure interaction.
The principal goal of this research is developing physics-based, reduced-order, analytical models of nonlinear fluid-structure interactions associated with offshore structures. Our primary focus is to generalize the Hamilton's variational framework so that systems of flow-oscillator equations can be derived from first principles. This is an extension of earlier work that led to a single energy ...
