Abstract:
In this paper,the three dimension numerical simulation models(FLUENT) are built based on some power plant engineering.The path lines of the hot moist of the forced draft cooling towers air are simulated,and the hot moist reflow phenomenon are studied.The effects of the operation plans,the weather conditions and the cross wind on the distribution the reflow rate of the hot moist air are studied.The result indicates that the maximum reflux rate reaches 17%,leading to the temperature of dry bulb at the air inlet increasing by 0.77℃ and wet bulb increasing by 1.67℃.
