Numerical Simulation of Vortex-Induced Vibration of TTR and SCR

a 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...

A Complementary Numerical and Physical Investigation of Vortex-induced Vibration

Results are presented from low Reynolds number experimental investigations of vortex-induced vibration and comparison is made with results from corresponding twoand three-dimensional direct numerical simulations. It is shown that three-dimensional simulations are required to reproduce the response envelope observed experimentally. Phase-averaged contours of spanwise vorticity demonstrate the pr...

Numerical simulation of vortex-induced vibration of two long flexible circular cylinders in tandem

A quasi three-dimensional numerical model is developed to study vortex-induced vibration (VIV) of two tandem flexible circular cylinders. In this model, the whole cylinder is divided into many sections along its length. The hydrodynamics of each section are represented by the solution of the two-dimensional Navier-Stokes equations. The dynamic response of the flexible cylinder is predicted by t...

Numerical Simulation of Vortex Breakdown by the Vortex-Filament Method

Coupled Simulation of Vortex Induced Vibration of Slender Structures as Suspension Bridges and Offshore Risers

An important eld in computational science and engineering is the simulation of the coupled problem of uid ow interacting with a moving structure. A common notation for this is uid-structure interaction (FSI) problems, which include both aeroelasticity and hydroe-lasticity. Herein we give an overview of results obtained within Fluid-Structure Interaction-Structural Design (FSI-SD) a project that...
