| 摘 要： | 与风洞试验相比,数值风洞具有成本低、周期短、适用广泛等诸多优点,然而由于缺乏足够的研究与验证工作,其精度及可靠性还没有被广泛接受。应用CFD方法建立两个典型高层建筑的数值风洞模型,进行建筑表面风压的模拟与验证,计算结果表明,数值风洞可以很好的反应建筑风压的分布规律,除背风面等少数区域,风压模拟结果具有较好的精度,具有很好的参考价值。 |

| Abstract: | Comparing to wind-tunnel experiments,the numerical simulation has many advantages,such as low-cost,short cycle,and broad application.However,due to the lack of adequate research and verification work,its accuracy and reliability have not been widely accepted.In this paper,wind pressure of two typical high-rise buildings is tested by numerical wind-tunnel.The numerical results are in very good agreement with the experimental results,except in some leeward regions.These indicate that the numerical wind-tunnel can provide a good reference for building design and environmental assessment. |
| Keywords: | numerical wind-tunnel CFD high-rise building wind pressure coefficient |
