自然通风间接空冷塔优化布置的数值模拟研究

Numerical simulation of the indirect air cooling tower layout optimization

自然通风间接空冷塔的布置间距以及与主风向的关系是电厂总图设计需关注的重要问题。该文采用FLUENT软件及其散热器模型,对两个自然通风间接空冷塔的布置间距和受不同自然风向影响的空冷塔布置进行了数值模拟研究。计算结果表明:自然通风间接空冷塔的净间距不宜小于50 m;两个间接空冷塔的连线宜与自然风的主风向平行。该结论可为相关工程设计提供参考和依据。

The relationship between the layout space of natural ventilation indirect dry cooling towers and main wind direction is much concerned by Power plant drawing design. In this paper, we use FLUENT software and the radiator model to implement numerical simulation about two aspects as follows： one is the layout space between two natural ventilation indirect dry cooling towers, and the other is the influence of different wind directions on layout of the cooling towers. The result shows that the distance between two towers is suggested to be no less than 50 meters and the connecting lines between two towers should be parallel to the main wind direction, which may offer references for the other engineering designs.
