Effect of cross-sectional shape on the response to Karman vortex shedding
Abstract
Experimental data on Karman vortex shedding from circular and rectangular cylinders are reviewed and analyzed. The data are presented graphically, and it is found that the coupling between the motion of the body and the flow separation (the so-called moving-wall effect) plays a significant role in both cases, while the interaction between the shed vortices and the body is important only for the rectangular cross section because of the aft profile of the circular cylinder.
