摘要
双塔型高层建筑周围存在着较为复杂的绕流风场,其表面风压的分布是结构和覆面设计的依据。结合一双塔联体型高层建筑的周围风场和表面风压的研究,以Reynolds时均数值模拟的方法,采用k-εRNG湍流模型,对其风场和风压进行了数值模拟。模拟的风压结果与边界层风洞试验的测试结果进行了比较,两者之间吻合较好,表明通过数值模拟可较准确迅速地获得该类体型建筑表面风压分布的规律和特征。
The wind field around a building which consists of double towers is complex and the design of framework and cladding lie on its local distribution of windinduced pressures Combined with the research on wind field around and windinduced pressures on a building of double towers, its wind flow and windinduced exterior pressures have been predicted using the numerical simulation technique The numerical simulation was based on the Reynolds averaged equations, in which the k-εRNG turbulence model was used Compared with the boundary wind tunnel test data, the computed wind pressures have a good agreement with it Through the numerical simulation, the distribution regularity and behavior of the wind pressures on the samestyle buildings were obtained exactly and rapidly
