Abstract
Undamped transverse-only Vortex-Induced Vibration (VIV) of a rigid square cylinder is investigated numerically at a Reynolds number of 250. A stabilized space-time finite-element formulation is employed to discretize the governing equations of fluid motion in two dimensions. The reduced speed is varied from 3.5 to 9.5. For the entire range of reduced speed, synchronization between cylinder oscillations and vortex shedding is 1:1. The response consists of initial and lower branches. Two kinks are present in the response curve; the first one appears at a reduced speed of 4.7 and indicates the onset of lock-in.
