Abstract
Packing of the cooling tower, in which the heat exchange mainly, plays a decisive role in the cooling performance of the cooling tower. This thesis conducted the three-dimensional numerical simulation of the cooling tower based on CFD software FLUENT and analysed the physical characteristics of the gas-liquid two phase. The axial flow fans with two different blade profiles are simulated to make the cooling tower has different total pressure under the same air volume, concluding that the total pressure of the cooling tower has little influence on the performance of the cooling tower. Also, the influence of the packing resistance coefficient and height on the cooling performance is studied, finding that increasing the packing height is more conducive to improving the cooling performance compared with the increase of the packing resistance coefficient.
