摘    要:采用数值模拟方法对上海世博会气象馆进行了平均风压数值模拟,比较了4种较适合于结构风工程的RNG k-ε,SST-k-ω,SSG-RSM和BSL-RSM湍流物理模型,包括体型系数、表面合力、合力矩及湍动能结果,同时结合风流动特性分析了其规律性和差别的原因,并得到SST-k-ω,BSL-RSM与SSG-RSM模型各有优势,而RNG k-ε模型稍差的结论.最后研究了有无干扰情况下的场馆表面平均风压系数,分析了风干扰的原因.

关 键 词:雷诺平均法  湍流物理模型  平均风压

Abstract:Numerical simulation method is adopted to simulate the mean wind pressure of Shanghai EXPO Meteo World Pavilion. Four turbulence models (RNG k-ε, SST-k-ω, SSG-RSM and BSL-RSM), appropriate for structural wind engineering, are applied in this paper and compared shape coefficient, overall superficial forces and moments, and turbulence energy. In addition, with the analysis on regularity and difference of wind flow characteristics, conclusion is obtained that SST-k-ω ,BSL-RSM and SSG-RSM has different advantage but RNG - k-εis the worse. Finally, mean wind pressure coefficient of the pavilion is researched under the conditions of with and without interference. The reason of wind interference is also analyzed.
Keywords:RANS  turbulence model  mean wind pressure  wind interference
