Resumo
The 3D flow around a circular cylinder free to oscillate transversely to the free stream was simulated using ComputationalFluid Dynamics (CFD) and the Spalart-Allmaras Detached Eddy Simulation (DES) turbulence model for a Reynolds numberReD104. Simulations were carried out for a small mass-damping parameter m*ζ=0000858, where m*=3.3 and ζ=000026.We found good agreement between the numerical results and experimental data. The simulations predicted the high observedamplitudes of the upper branch of vortex-induced vibrations for low mass-damping parameters. © by The International Society of Offshore and Polar Engineers.
