abstract
Flow past a fixed and freely-vibrating circular cylinder is studied numerically using an unsteady, overset-grid (Chimera), Reynolds-Averaged Navier-Stokes (RANS) method. The VIV flows selected for study correspond to low mass ratio and low damping at high Reynolds numbers. Some numerical results using large eddy simulation (LES) are also presented for transitional flow.
