| 摘 要： | 为验证数值模拟在大跨封闭屋盖平均风压应用的可行性,采用数值模拟的方法对沈阳奥林匹克体育中心综合体育馆屋盖平均风载进行了分析,得到屋面上不同风向下的总升力与平均风压分布.分析了总升力随风向变化的规律性,并将平均风压分布与风洞试验结果进行了对比分析.可看出两种方法在三边有屋檐的屋面上的结果接近,说明数值模拟方法模拟封闲大跨屋盖的平均风压分布可行.通过悬挑边和圆弧边对比,可看出SST K-w湍流物理模型在计算以分离流为主的流场时,精度很好.最后研究了不同形式屋檐屋面上锥涡分布的特点.

| Abstract: | In order to verify feasibility of the application of numerical simulation in average wind pressure of large-span-closed roof,the numerical simulation of mean wind pressure on the roof of Shenyang gymnasium is carried out.The distribution of mean wind pressure and the lift force under different wind directions are obtained and the laws of the lift force are also analyzed.Meanwhile,the comparison between the results of the numerical simulation and wind tunnel test shows that the results on the roof surfaces w... |
