摘要
对侧风条件下空冷塔内外的空气动力场进行了数值模拟,分析了塔外速度分布、压力分布,并与相应条件下理想流体圆柱绕流的情况进行了比较。计算结果显示了不同侧风风速条件下空冷换热器水温降沿周向的变化以及塔内温度分布的变化,指明了侧风影响空冷塔运行的主要部位和特点。
According to the cross wind ,the aerodynamic field inside and outside an air cooling tower is numerically simulated. The velocity and the pressure distribution outside the tower are analyzed. The results are compared with the ideal gas flow bypassing a cylinder. The variances of temperature drop in the air cooling heat exchanger around the tower under a different cross wind and the variance of air temperature distribution inside the tower are showed. The effect of the cross wind on the main places and characteristics of the air cooling tower are pointed out.
