Abstract

The unsteady wake behind a circular cylinder was studied and compared with numerical results. The location and evolution of coherent structures, or vortices, in the ow were analyzed to facilitate the understanding of the complex vortex shedding physics in the near wake region. This understanding is critical to the control of vortex shedding from bluff bodies. The two-dimensional velocity data was collected using a 2D DPIV measurement system. Eulerian vortex criteria were applied along with a Lagrangian coherent structures (LCS) analysis to determine the properties of the wake.
