| 中文摘要: |
| 为研究群体高层对风速风向的影响，以与群体高层类似的嘉峪关酒钢电厂冷却塔群为例，在电厂冷却塔群附近及空旷地带设立2个测风塔，进行风速、风向对比观测，研究冷却塔群间“狭管效应”对风速风向的影响。数据分析表明，冷却塔群的存在使10 min平均风速降低，但是对2 s瞬时风速影响不大，同时2 s最大风速与10 min平均风速比值增大。 |
| 英文摘要: |
| In order to study the influence of high-level groups on wind speed and wind direction, taking the cooling towers of the Jiayuguan Jiuquan Iron and Steel Power Plant similar to the high-level of the group as an example, two wind measuring towers are set up near the cooling towers of the power plant and in the open area to compare wind speed and wind direction. The Influence of "venturi effect" on wind speed and wind direction between the cooling towers groups is studied. The data analysis shows that the presence of the cooling towers groups reduces the average wind speed for 10 minutes, but has little effect on the instantaneous wind speed at 2 seconds. At the same time, the ratio of 2s wind speed to 10 min wind speed is increased. |
