本文介绍热车间双跨厂房模型淹没在边界层内,正面受风冲击时的风洞试验结果。试验证实。每点的风压系数不是常数,窗户开启的位置和面积,对风压系数有影响,在天窗之间部位,测量到动压系数的最大变化天窗流出的流量越大,两天窗间的动压系数增大越多,随着开启窗户的增多,迎风面动压系数略有增大,背风面动压系数则略有减小。 This paper presents the wind tunnel test results of a double-span factory model submerged in the boundary layer in a hot shop and impacted by wind. Test confirmed. The wind pressure coefficient at each point is not a constant. The position and area of ​​the opening of the window have an influence on the wind pressure coefficient. In the part between the sunroof, the dynamic flow coefficient between the two skylights is measured as the flow rate of the largest change in the dynamic pressure coefficient of the sunroof. The more the coefficient increases, the larger the dynamic pressure coefficient on the windward surface increases with the increase in the number of open windows, and the dynamic pressure coefficient on the leeward surface decreases slightly.
