| 摘 要： | 描述了一个电厂附近的山地对该地区风环境影响的风洞实验研究。应用热线、烟线技术测量并显示了山地与沟谷附近的风场。对水平与垂直风速剖面、湍流度进行了分析,并讨论了其与地形特性的关联。实验结果揭示实验室模拟傍山地区特殊的风环境对建设高耸的冷却塔具有重要的指导意义。

| Abstract: | This paper describes a wind tunnel testing of the influence of hills and valleys near a power plant on the wind circumstance.Using hot wire and smoke wire the flow fields have been measured and visualized,and the vertical and horizontal wind profiles,turbulence intensity have been analyzed.The relation between flow fields and landform also has been discussed.The results show that experimental simulation of local wind field is very helpful for building cooling towers near hills. |

| Keywords: | wind field around hills wind profile turbulence intensity flow visualization |
