... ABSTRACT In this paper a novel experimental investigation into the vortex formation in the wake of a fixed and an oscillating circular cylinder is presented. The aim of the study is to acquire a better understanding of the complex three-dimensional vortex flow around the cylinder at high...

... includes effect of previously separated vortex pair, was also proposed (Otsuka et al., 2000). The purpose of this paper is to improve the two-vortex.pair version of the symmetrical vortices model to be applicable to an irregularly oscillating cylinder. In order to develop the model of vortex formations...

However, when the body contains sharp corners or edges, e.g. a thin walled wave barrier, flow separation inevitably occurs and viscous effects such as a vortex formation...
