摘要:

在湍流中对一立方体模型周围的静压场进行风洞探测试验研究,并对该立方体进行计算流体动力学(CFD)数值模拟.与风洞试验结果的对比显示,CFD方法在静压场计算中的适用性良好.对足尺立方体结构和更多类型建筑物进行CFD计算.结果显示,各种类型建筑物的静压场分布型式较相似,可以使用相同的数学公式来描述不同类型建筑物静压场主要方向的分布规律,并推断静压场的边界.研究静压场的分布规律发现,建筑物周围近距离范围内有2条狭长地带能够用于快速测量参考静压,称为“静压走廊”,通过一定方法可以确定其位置及走向.

Abstract:

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.
