TTU标准模型表面风压大涡模拟及风洞试验的对比研究

LARGE EDDY SIMULATION AND WIND TUNNEL TEST ON TTU BUILDING MODEL

  • 摘要: 以低矮建筑标准模型TTU(德州理工大学)模型为考察对象,基于专业计算流体动力学软件FLUENT,对1:50缩尺模型进行了大涡模拟研究,并在边界层风洞中对该比例模型进行了风洞试验研究,将大涡模拟结果与风洞试验、场地实测数据进行了比较。结果表明,大涡模拟得到的建筑模型表面平均及脉动风压与风洞试验、现场实测结果吻合较好,没有雷诺数效应的足尺低矮建筑表面的动态风压可通过缩尺模型的大涡模拟进行预测。

     

    Abstract: Based on large eddy simulation, the wind pressure on the surface of standard low-rise building model TTU at a scale of 1:50 was numerically simulated through computational fluid dynamics software Fluent. At the same time, the wind tunnel test of TTU model with the same scale was carried out. The results of numerical simulation were compared with those obtained from the wind tunnel test and the field observation. The comparisons showed that the mean and dynamic pressure distribution on the model surface obtained by LES simulation is in good agreement with the results from the wind tunnel test and field observation. Thus, large eddy simulation combined with a scaled model can be used to predict the dynamic wind pressures on full-scale low-rise building with no Reynolds number effect.
