文摘:通過風洞實驗研究了風向對兩個和三個鄰近建築風壓分佈的影響特性.實驗結果給出了在不同風向角下,作用於受擾建築上的平均和脈動風壓系數.當受擾建築處于下游位置時,建築之間的干擾效應主要表現為遮擋影響,建築物上的總體風壓系數不是很大,但在建築物表面上有時會產生局部較大的負壓系數.另外,在某些風向角下由於受到上游分離氣流的影響,在下游建築的局部表面又會出現較大正壓.這些結果可供建築布置和結構設計時參考The doppler radial winds from the terminal doppler weather radar ( tdwr ) 0. 6 - degree elevation scan over the hkia and its western approach were generally away from the radar ( positive radial velocity - - warm colours ), consistent with the low - level east - southeasterly flow ( figure 12 )
