Abstract:
High wind suction always occurs at the edges and corners of large-span low-rise flat roofs, which can lead to severe damage to roof elements and even to the overall destruction of the roof. The passive vortex generator (PVG), a new device which can generate streamwise vortices, is proposed to mitigate the extreme wind suction on a low-rise large-span flat roof. Wind tunnel tests were conducted to investigate the control effect of PVGs, and parametric analysis was performed, with parameters including the height, length, opening angle, tilt angle and interval of PVGs.
