| 摘 要： | 基于专业计算流体动力学软件平台FLUENT6提供的标准k?ε等多种湍流模型对大气边界层中的TTU(Texas Tech University Building Model)标准低矮建筑的定常风场进行了数值模拟,并将计算结果与场地实测数据及同济大学TJ-2风洞试验结果进行了比较。结果表明,多种湍流模型均能为工程应用提供有效参考,且对于此种体形简单的建筑复杂的雷诺应力模型的预测结果并不优于简单的涡粘模型,这为钝体绕流现象的数值模拟研究提供了有利依据。

| Abstract: | Based on various turbulence models, i.e. standard k ? ε model etc. provided by professional computational fluid dynamics software Fluent 6, the 3D steady wind flow field around standard low-rise building TTU in atmospheric boundary layer is numerically simulated. The results of numerical simulation are compared with TTU field measured data and Tongji University TJ-2 wind tunnel test data. The comparisons show that several turbulence models can give useful results from the aspect of engineering application, and the simulation results of complex Reynolds stress model are no better than simple Eddy viscosity models for such simple shape building. This provides a foundation for numerical simulation study of wind flow around bluff body. |
