Abstract

A technique of high-image-density particle image velocimetry and a method for simultaneous force measurement reveal the mechanisms leading to remarkable changes in the lift force on an oscillating cylinder, located both well below and adjacent to a free-surface. Patterns of instantaneous vorticity are related to the instantaneous lift; this approach defines the distinctive features of the near-wake and cylinder loading due to proximity of the free-surface.
