为研究塔型因素、复杂山形对双塔布置冷却塔干扰效应的影响规律,以国内在建210m高双塔布置冷却塔为例,基于风洞试验获得了不同塔型冷却塔考虑复杂山形双塔布置冷却塔表面压力分布模式。在此基础上,对比分析了三种塔型冷却塔的平均风压和脉动风压分布规律,探讨了考虑复杂山形和周边建筑干扰时塔型因素对干扰效应的影响,最后针对最不利工况进行了复杂山形和塔群之间的风致干扰机理研究。结果表明塔型因素对冷却塔干扰效应影响显著。本文主要结论可为此类复杂地形下双塔组合冷却塔塔型选取提供科学依据。
In order to study the influence of tower-shaped factors and complicated Yamagata on the interference effect of cooling tower with twin towers, taking the 210m high twin tower cooling towers in China as an example, different tower cooling towers are taken into account for wind tunnel tests to consider complex Yamagata twin towers Arrange cooling tower surface pressure distribution mode. On this basis, the distribution of average wind pressure and fluctuating wind pressure of three tower cooling towers are comparatively analyzed, and the influence of tower-type factors on the disturbance effect when considering the interference of complex mountainous and surrounding buildings is discussed. Finally, according to the most unfavorable conditions The mechanism of wind-induced interference between complex Yamagata and tower groups was studied. The results show that tower-type factors have a significant impact on the cooling tower interference effect. The main conclusion of this paper can provide a scientific basis for tower type selection of twin tower combined cooling towers under such complex terrains.
