摘要

为研究大型冷却塔典型六塔布置下的群塔干扰效应，开展了矩形布置和菱形布置两种群塔组合、三种塔间距下的刚体模型测压风洞试验，探讨了基于气动荷载的干扰因子随群塔布置形式、塔间距和风向角的变化规律，分析了最不利工况下的塔筒表面平均风压和脉动风压分布特征。结果表明：六塔组合下的菱形布置形式相比矩形布置的群塔干扰效应更大，受干扰效应影响最大的冷却塔位于来流下风向；两种布置形式下干扰因子对风向角的敏感性要大于塔间距；受扰塔的表面平均风压和脉动风压呈非对称分布，干扰效应增大了平均风压在侧风区和背风区的吸力以及脉动风压的数值大小。

Abstract

To investigate the wind-induced interference effects in a typical six-tower arrangement of large cooling towers

wind tunnel pressure measurements on rigid models were conducted for two tower layouts—rectangular and rhombic—with three different tower spacings. The variation patterns of interference factors based on aerodynamic loading with respect to tower group layout

tower spacing

and wind direction angle were investigated. The distribution characteristics of average and fluctuating wind pressures on the tower surface under the most unfavorable conditions were analyzed. The results showed that the rhombic layout exhibited stronger tower group interference effects compared to the rectangular layout

with the most significantly disturbed cooling tower located in the leeward direction of the incoming wind. Moreover

the sensitivity of the interference factors to wind direction angle was greater than that to tower spacing for both tower layouts. The distribution of average and fluctuating wind pressures on the surfaces of disturbed towers was asymmetric. The interference effects increased the suction of average wind pressures in the side and leeward wind regions

as well as the magnitude of fluctuating wind pressures.
