摘要
采用CFD技术模拟冷却塔气流分布和气流温度分布特性,提出对冷却塔加装10m的基础和3m的导风筒的措施,改善冷却塔的运行效果。结果表明:改进后,冷却塔的热羽流得到有效抬升,填料进风口的返混现象得到明显改善。
IThe CFD technology is used to simulate the air flow velocity field and temperature field of the cooling tower. To improve the working condition of the cooling tower, measures of uplifting the cooling tower＇s foundation by 10 meters and installing 3-meter-long air duct are taken. Thus, heat plume flow is upraised and flow back mixing phenomena at the bottom entrance is decreased.
