中文摘要：

采用TTU（Texas Tech University Building Model）标准低矮建筑模型为研究对象,基于Fluent的计算流体动力软件平台,分析了网格划分、湍流模型等因素对数值模拟结果的影响,并计算了不同雷诺数下结构表面风压.分析结果表明：各种比例模型下类似网格分布中,保证模型表面y＋数值的一致,网格对计算结果的影响有限;不同雷诺数条件对TTU标模屋檐处风压分布影响明显.

英文摘要：

On the basis of computational fluid dynamics（CFD） software Fluent6.3,the standard low-rise building model of TTU is investigated.Influences of mesh arrangement,turbulence model on numerical simulation results are analyzed;and wind pressure of TTU are calculated for different Reynolds numbers.Calculating results show： similar grid arrangement in different scale models had no influence on simulation,if y＋ value of model surface are same;and wind pressure distributions on TTU model＇s roof have visible diversity at different Reynolds numbers.
