摘　　要：文章研究建筑风驱雨(wind-driven rain,WDR)分布受风阻效应的影响,对建筑立面不同部位受风阻效应影响的特性进行定量研究。基于欧拉多相流(Eulerian multiphase,EM)模型建立WDR数值模拟方法,针对前后串列建筑布局,考虑下游建筑高度和降雨强度变化,模拟分析风阻效应下上游建筑立面WDR的分布规律,获取风阻效应影响特性。结果表明,风阻效应对建筑立面WDR抓取率有显著的削减作用,且当下游建筑高度增大时,风阻效应的影响愈加明显。The wind-driven rain(WDR)distribution of buildings is significantly affected by the wind-blocking effect.In this paper,the characteristics of the different parts on the building facades due to the wind-blocking effect are quantitatively evaluated.The WDR numerical simulation method is established based on the Eulerian multiphase(EM)model.The tandem layouts are used and different downstream building heights are selected.Considering the change of rainfall intensity,the WDR distribution law of the upstream building windward facade is analyzed and the WDR distribution characteristics on the windward facade are obtained.The results show that the wind-blocking effect significantly reduces the WDR catch ratio of the building facade,and the influence of the wind-blocking effect becomes more obvious when the downstream building height increases.
