Abstract:

Based on commercial software Fluent and RNG k-ε model, wind pressure distributions around concave low-rise buildings with eaves are investigated numerically. The effects of roof pitch, roof shape and cornices forms on mean wind pressures over the roof and the flow around the building are analyzed. The results show that wind pressures over the roof are remarkably affected by both geometric parameters and wind direction. Wind pressures over the roof increase with the increasing of height-width ratio of the building. Wind pressures over windward roof decrease while those over leeward roof increase with the increasing of roof pitch. Furthermore, both vertical and horizontal cornices greatly change the wind pressure distribution around the roof.
