Abstract	:	Cooling towers are used to reject heat from water to the atmospheric air by means of heat and mass transfer. Since some of the water, which is in direct contact with air, is evaporated in the air the process is also known as evaporative cooling. The thermal analysis of wet cooling tower has received considerable attention in recent years. The effect of fill packing system on the performance of cooling tower has been the major consideration of many researches. In the present numerical study, the analysis of the thermal performance of cooling tower is carried out for different types of the fill packing available in the literature as well as from different manufacturers. Also, a comparison is made for the thermal characteristics of a cooling tower when a different type of fill packing system is used. In this regard, an experimental data for a small cooling tower having a capacity of 20 gal/min is used to validate the numerical results. It is found that the simulation results are within 1.2% of the experimental values. In addition to the above investigation on fill packing system, a sensitivity analysis on the thermal characteristics of cooling tower is also presented with respect to the important parameters such as inlet water temperature, wet bulb temperature, tower characteristics, etc.
