Abstract

The hydrodynamic forces and wake characteristics of a forced streamwise oscillating circular cylinder were investigated numerically over a large parameter space of oscillation amplitude and frequency. Specifically, the wake synchronisation modes for a near-wall oscillating cylinder, the far-wake characteristics of an isolated oscillating cylinder, and the boundary-layer transition for an oscillating cylinder in still fluid are examined. A number of new flow phenomena, e.g. period doubling and transition to quasi-periodic within the primary synchronisation region, are observed and the corresponding physical mechanisms are explored.
