摘 要：
本文采用CFD(计算流体动力学)软件STAR-CCM+,模拟不同风向角下泰安文化艺术中心的表面风压,并与实际风洞试验结果比较验证;采用经过验证的数值计算方法,分析了简化几何情况下的泰安文化艺术中心尺度效应对实际评估风载荷带来的影响。结果表明:CFD数值计算方法能够真实反映建筑表面风压特性;尺度效应对建筑表面的平均风压系数影响微弱,但是对建筑尾部的流场分布及流速大小有显著影响。

摘 要：
We use the CFD(Computational Fluid Dynamics) software STAR-CCM to simulate the surface wind pressure of the Taian culture and art center at different wind direction angles, and compare with the actual wind tunnel test results. This paper analyzes the influence of the scale effect of Taian culture and art center on wind load under simplified geometry using the verified numerical calculation method, the results show the CFD numerical method calculation can truly reflect the wind pressure characteristics of the building surface, and the scale effect has weak effect on the average wind pressure coefficient of the building surface and significant effect on the flow field distribution and velocity of the building tail.
