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 the feasibility of numerical simulation in the application of average wind pressure of large-span closed roof, the average wind load of the comprehensive gymnasium of Shenyang Olympic Sports Center was analyzed by numerical simulation method, and the total lift and average wind pressure distribution of different wind downwards on the roof were obtained. The regularity of total lift with wind direction was analyzed, and the average wind pressure distribution was compared with the wind tunnel test results. It can be seen that the results of the two methods on the roof with eaves on three sides are similar, indicating that the numerical simulation method is feasible to simulate the average wind pressure distribution of the closed large span roof. By comparing the cantilevered edge and the circular arc edge, it can be seen that the SST K-w turbulent flow physical model has good accuracy in calculating the flow field dominated by separated flow. Finally, the characteristics of the distribution of cones on different forms of eaves roofs are studied.
