Fill Depth

Based on the heat and mass transfer theory and characteristics of the FLUENT software, a three-dimensional numerical simulation platform composed by user defined functions had been developed to simulate the thermal performance in a natural draft wet cooling tower. This platform was used to study a typical hyperbolic natural draft wet cooling tower with different fill types. The variations of the flow and temperature field in the cooling tower caused by the two different methods of fill were investigated. It is found that the outlet water temperature will decrease due to the non-uniform fill depth. The non-uniform fill depth is beneficial to increasing the efficiency of the cooling tower.

Mass Transfer Theory

Based on the heat and mass transfer theory and characteristics of the CFD software, a three-dimensional numerical simulation platform had been developed to study the thermal performance in a natural draft wet cooling tower. This platform was validated using the measured results of a running cooling tower. The flow and temperature field in the cooling tower were investigated. It is found that the water temperature and flow field can be correctly calculated using this platform. The cooling efficiency could be improved due to non-uniform fill and water distribution methods.
