Therefore, the vorticity of the fluid interacts with the vortex shedding from the cylinder.
The tapering wings produce an aerodynamic shape that helps reduce structural loading due to wind vortex shedding.
We adopted a method of perforating the vane to reduce the vortex noise (ZHANG & GU, 1989; WU & LI, 2001) that can make the air on the pressure side flow to the suction surface, prevent the fluid breakdown, and even reduce and inhibit the tail vortex shedding.
The vortex shedding alternated from one side of the bridge to the other, creating a pressure imbalance that resulted in an oscillatory lift, leading to the total destruction of the bridge.
In addition, separation bubbles can collapse intermittently, and the flow in the building wake is characterized by vortex shedding from the leeward building sides and roof.
