中文摘要：
以国际通用的低矮建筑标准模型TTU（德州理工大学）模型为考察对象，在同济大学TJ-2建筑风洞中进行了1：50缩尺模型的风洞试验研究．通过风洞试验数据与原型场地实测数据的对比，以评估风洞模拟技术的可靠性；同时，基于国际商用软件Fluent的RSM（雷诺应力）模型和CFX的SST（剪切应力运输）模型，从数值模拟的角度研究了TTU实尺度模型的定常绕流场．将数值预测的压力场与实测结果及缩尺模型风洞试验数据进行了比较，分析了风洞试验与场地实测之间、数值模拟与试验之间的异同，得到一些有参考价值的结果．
英文摘要：
The wind tunnel test of the TTU （Texas Tech University） Building Model, an international standard model, at a scale of 1 ： 50 was carried out in TJ - 2 boundary layer wind tunnel of Tongji University. With a comparison of results of wind tunnel test and those of field measurements of the fullscale TTU model, the reliability of wind tunnel test was evaluated. Further more, the steady flow field of the full-scale TTU model was computed with the well-known Fluent RSM（reynolds stress model） and CFX SST（shear stress transport） model, and a comparison is made among the pressure fields obtained respectively from the numerical predictions, the field measurements and the wind tunnel test. Based on the analysis of the differences between wind tunnel test and field measurements and the differences between numerical results and test data, some referential conclusions are drawn.
