大型冷却塔塔群效应的研究与探讨

Discussion on effect of large group cooling towers

风荷载对单个冷却塔的影响与集中布置的冷却塔影响有不容忽视的差异,通过冷却塔模型测压实验,研究实验满足的相似条件、塔表面的雷诺数效应模拟以及塔表面的风压分布的特征.在考虑群塔效应及在周围复杂建筑物场地条件下,提出实验条件、实验方法,得出群塔相对于单塔的风压影响系数.依据模型实验及研究成果,对群塔中心距按1.5d、1.8d及2.0d布置分别进行比较,优化总平面布置间距,并总结了群塔效应对冷却塔结构设计的影响.

The difference is recognized between single tower and group towers by the action of wind.Similitude conditions to satisfy experiment and simulated Reynolds number effect and character of wind pressure upon tower surface will be discussed through experiment of measured pressure acting on cooling tower model.The experimental condition and experimental method will be put forward on condition of group towers effect and complex building all around.It comes out infection coefficient of wind pressure between singl...
