| Abstract (Chinese): |
为获得攒尖四坡屋面的风致雪漂移规律棳基于欧拉灢欧拉方法和风雪单向耦合假定棳运用计算流体动力学 软件棳选取 MIXTURE 斿模型分别对立方体周边和高低屋面上的风致雪漂移运动进行数值模拟棳将模拟结果与两者的 实地观测数据对比棳探讨分析数值风洞的关键技术和参数设置棳验证数值模拟方法的合理性与可靠性暎依据攒尖 四坡房屋的使用功能要求棳设计分析模型与分析工况棳在试算的基础上对屋面进行分区暎以风5m/s, 7m/s.9m/s,11m/s,13m/s 风向角0°, 15°, 30° 以及屋面 45° 椀 25°, 30°, 34°, 40°, 45° 为分析参数棳对攒尖 四坡房屋的棻棽棸种工况进行数值模拟棳得到屋面各分区侵蚀沉积的基本规律棳提出可用于抗雪设计的屋面积雪分 布系数暎研究表明棳风向角的改变会使屋面积雪分布状态发生较大程度的变化棳风速和屋面坡度的变化对屋面整 体积雪量有较大影响暎 [ABSTRACT FROM AUTHOR] |
