摘　　要：文章研究建筑风驱雨(wind-driven rain, WDR)对建筑内部的破坏,基于欧拉-欧拉多相流模型,考虑具有恒定开孔率下的不同形状开口,即正方口、竖直口和水平口,通过模拟不同风速和雨强下的WDR场,分析开洞建筑WDR分布特性及洞口形式对WDR分布的影响规律。结果表明,洞口形式和风速的变化对开洞建筑迎风立面和室内地面抓取率影响显著,只有当雨强增大到一定程度时,开洞建筑迎风立面和室内地面抓取率才有显著变化。The damage of wind-driven rain(WDR) to building interior is studied. Based on the Euler-Euler multiphase model, considering the openings of different shapes with constant opening rate, namely square opening, horizontal opening and vertical opening, the WDR distribution of the building with opening and the influence of the opening form on the WDR distribution are analyzed by simulating the WDR field under different wind speed and rain intensity. The results show that the change of the opening form and wind speed has a significant effect on the catch ratio of windward facade and indoor ground of the building with opening, and the catch ratio changes significantly only when the rain intensity increases to a certain degree.
