Wind tunnel test and numerical simulation of wind-induced static pressure field around a building

The static pressure field around a cube in turbulent flow was detected in wind tunnel, and computational fluid dynamics (CFD) numerical simulation was conducted. Comparison between the results from the computation and the wind tunnel test was performed, which indicated that the precision of CFD technology is enough to compute static pressure field distributions around buildings. Then the full-scale cube and more types of full-scale buildings were simulated by CFD method. Results show that static pressure distribution patterns of different buildings are similar. The same formulas can be given to describe main directions of static pressure fields around dissimilar buildings, and the boundaries are concluded. More investigations of static pressure fields reveal that there are two narrow strips of regions near a building which can be used to quickly measure reference static pressure and so be named static pressure corridor, and the method to find their positions and directions is proposed.
