Vortex-induced vibration on 2D circular riser using a high resolution numerical scheme

This paper presents a high resolution numerical method for vortex induced vibration (VIV) simulation on the fluid structure interaction (FSI) of circular cylinder which represents a two dimensional marine riser. For the VIV case, the cylinder is elastically mounted and is modeled as a springmass oscillation system. Based on a new proposed elemental velocity vector transformation (EVVT) method, a finite-volume total variation diminishing (TVD) approach developed recently for solving unsteady Reynolds Averaged Navier-Stokes (URANS) equation with the RNG turbulence model was used to simulate the key hydrodynamic parameters such as lift coefficients. The four-stage Runge-Kutta method is used to solve the dynamic response equation of the structure. The FSI prediction results are compared with the available experimental data and showed a good agreement in a wide range of Reynolds number, which provide a good picture of real physics of phenomenon including the Karman vortex streets with different vortex modes with regard to the reduced velocities.
