Based on the above analysis, the noise could be reduced if we can change the parameters of vane's boundary layer, delay the separation of boundary layer and prevent vortex shedding, or change the energy of trailling vortex.
For the cylinders with both ends fixed, it had been shown that the surface pressure distribution oscillates at the vortex shedding period and that pressure variations are consistent with periodic changes of the circulation around the cylinder body.
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.
