摘要:
对方形土楼进行风洞试验和数值模拟,在数值模拟风场和试验风场达到较好一致性时引入降雨过程的计算模型.采用该方法研究方形土楼在不同风速、不同降雨量,以及不同屋檐悬挑长度下迎风墙面风驱雨量的分布特征.研究结果表明:风驱雨侵蚀因子与风速和降雨量有关,并随风速及雨强的增加而增加;悬挑屋盖对屋盖附近区域的墙面形成有效的遮蔽作用.
Abstract:
The wind tunnel experiment of square earth buildings was tested, and calculation model of rainfall process was introduced when wind Fields of numerical simulation was well consistent with the test wind field. The distribution characteristics of wind-driven rainfall of earth buildings’ windward surface for different wind speeds, different rainfalls and different cantilever spans of eaves was discussed by this method. The results show that the erosion factor η of wind-driven rain is related to the wind speed and rainfall, and η increases with the increase of the wind speed and rainfall; the cantilevered roof forms shelter effectively the wall surface near the roof.
