摘要:
以闽南某大跨体育馆屋盖表面为例,进行风洞试验和计算流体动力学(CFD)数值模拟研究.通过风洞试验,得出体育馆最不利风向角下的平均风压系数和分块风压系数.基于CFX10.0软件平台,采用剪切应力输运(SST)k-ω湍流物理模型,对屋盖上的平均风压进行数值模拟.将计算结果与风洞试验数据进行对比,结果显示两者大体上基本吻合,证明数值模拟可以较准确地模拟实际大跨屋盖表面的平均风荷载.
Abstract:
The wind tunnel test and computational fluid dynamics(CFD) numerical simulation are carried out to investigate the wind load on a stadium roof with long span in south Fujian.The wind tunnel test finds out the average wind pressure coefficient and the regional wind pressure coefficient on the stadium roof under the most disadvantageouse wind direction.Meanwhile,the wind load distribution is numerically simulated using shear stress transport(SST) turbulent model based on the CFX 10.0 software platform.The tested wind pressures agree well with the numerical simulation pressures,therefore the accuracy of the numerical simulation is acceptable to calculate the average wind pressure on roof with long span.
