120m高排气塔加固设计

The Consolidated Design of 120m Exhaust Tower

排气塔后部横风向铅直向浓度分布仍基本保持高斯型，但源高风速大于2.6m/s时，烟流中心线明显向地面倾斜。

The cross-wind and perpendicular direction concentration distributions behind wind tower maintain basically Gaussion form , but central line of plume significantly slents to ground when mean wind velocity of source height is large than 2.6m/s .

排气塔扩散的风洞模拟研究

Study of wind tunnel modeling for wind tower dispersion

试验结果表明排气塔后部的尾流区能引起速度亏损、湍流增强和下冼现象。

Experiment results show that wake region behind wind tower can cause velocity deficit , turbulence excess and downwash phenomenon .

据此，我们推荐了倾斜高斯烟流模式及其参数算法系统予测排气塔后部的浓度分布。

Further more , tilted model of Gaussian plume and parameter system have been recommended to predict concentration distribution behind wind tower .

本文利用风洞模拟方法，对高约70米、直径29.7米园柱形排气塔的扩散规律进行了研究。

By Making use of wind tunnel method , this paper presents a study of dispersion for cylindric wind tower , whose height is about 70m and diameter of Cross section 29.7m .
