环境风对机力通风冷却塔冷却性能的影响

Effect of Ambient Wind on Cooling Performance of Mechanical Ventilation Cooling Tower

摘要: 通过对机力通风冷却塔进行数值模拟，研究环境风速及风向对机力通风冷却塔冷却性能的影响。结果表明：风速在0~16 m/s的范围内，机力通风冷却塔的换热功率随风速的增大而增大；风向角在0˚~90˚的范围内，机力通风冷却塔的换热功率随风向角的增大而减小。

Abstract: The influence of ambient wind speed and direction on the heat transfer power of mechanical ven-tilation cooling tower was studied by numerical simulation. The results show that the heat transfer power of mechanical ventilation cooling tower increases with the increase of wind speed in the range of 0~16 m/s. When the wind direction angle is in the range of 0˚~90˚, the heat transfer power of the mechanical ventilation cooling tower decreases with the increase of wind direction angle.
