Influence of the Francis turbine stay vane trailing edge shape on generation of Karman vortex street

, 2015
In the flow past bluff bodies for a certain range of velocity a periodical vortex shedding emerges which is known as von Kármán vortex street. This phenomenon causes the periodical alteration of pressure field which affects the body.
