Three Dimensional Vortex Shedding from Circular Cylinders

Abstract

Shear flow past slender bodies is a very common configuration in many real life situations. The flow-induced oscillations have profound effect on the stability of the structures. The long-term goal of the current research is to understand the three-dimensional behavior of the emerging unsteady flow field behind a slender circular structure when the upstream has a linear shear. Such an understanding will not only elaborate the frequency response of the unsteady forces on the cylinder but will also enhance the knowledge of the formation of spanwise vortical cells.
