摘要
基于风洞试验的结果分析了某机场航站楼屋面风压系数的特性,该机场航站楼屋盖表面以负压为主,大部分区域负压绝对值较小且分布均匀,迎风边缘部分负压绝对值及负压梯度均较大。接着结合计算流体动力学方法模拟了主要风向角下风速矢量的分布特性,进一步阐释了屋面风压分布形成的机理。
Based on the results from the wind tunnel test for an airport terminal,the characteristics of wind pressure on the roof surface were analyzed.Negative pressure dominates the whole roof surface for each wind direction.For most part of the roof,the absolute value of negative wind pressure is small and uniform,though large absolute value and large gradient of negative wind pressure occur on the windward surface.In order to further explain pressure generation mechanism,computational fluid dynamics (CFD) method was adopted to simulate wind speed field at typical wind direction.
