The role of separated flow is critical in practical bluff-body aerodynamics. For example, the maximum cladding suctions are usually observed near the leading edges of the buildings where the separated flow occurs. For slender structures such as tall buildings and bridges, the flow separated from the leading edges of the bluff body can interact with the wake separations, forming vortex shedding, and hence, significant cross wind forces. With the further disturbance of upstream turbulence, both the mean and fluctuation pressures are found to be altered significantly under the separated flows. |
