Research on Bluff Body Vortex Wakes
Abstract
This combined experimental- computational research addresses the problem of flow-induced forces on vortex-shedding bluff bodies. The long-term goals are to: (1) Improve understanding of the relation between the unsteady forces and vorticity histories in the near wake. (2) Use new results and insights to assess existing models for flow-induced unsteady forces and to seek alternative models. Immediate objectives are to obtain experimental and computational descriptions of velocity and vorticity fields in the near wakes of vortex-shedding bodies and the corresponding forces on the bodies for the cases of (1) stationary bodies, (2) bodies in forced oscillation, and (3) freely oscillating bodies.
