摘　　要：利用CFD软件CFX10,采用SSTk-ω模型和结构化网格对一平屋顶低矮房屋表面平均风压进行了数值模拟,结果跟实测以及风洞实验的数据吻合得较好,在此基础上模拟了4种带实体女儿墙的平屋顶低矮房屋屋顶风压.结果表明,4种女儿墙都能较好地减小屋顶角部的峰值负压.A numerical simulation was carried out for mean wind pressures acting on low - rise buildings with fiat roof utilizing the CFD software CFX10 with turbulent SST k - ω model and structured meshing. The results have a good coincidence with that of both full - scale and wind tunnel experiment. On the basis of that, numerical simulation was carried out on low - rise building with fiat roof and four types of solid parapets. The results show that parapets significantly reduce high suction peaks on roof comers.
