Abstract

The technique of high-image-density particle image velocimetry (PIV) can lead to instantaneous, global representations of the wake of a cylinder in a steady current and free-surface waves. Approaches to characterizing the complex patterns of the wake are described for several classes of experimental systems. Emphasis is on imaging in different planes, with the aim of providing insight into the quasi-two- and three-dimensional features of the near-wake. (C) 2001 Academic Press.
