Investigation on The effect of geometrical and ambient parameters on the performance of the Counter Flow Shower Cooling Tower

Wet Cooling towers (WET) that are widely used in different industries and air conditioning systems to remove excessive heat, have disadvantages and limitations. Cooling towers are one of the biggest heat andmass transfer devices that are in wide spreaduse. To overcome these limitations, Counter Flow Shower Cooling Tower (SCT) which is within the Wet Cooling Towers(WCT) category is presented. In this paper, analyzing heat and mass transfer in counter current open cooling towers. Using a computer program, the numerical solution will be executed and the effect of proper environmental and geometrical parameters will be reviewed and compared with experimental results in the recourses. Moreover, the effect of velocity variation, enthalpy, humidity, temperature and droplet diameter on the cooling efficiency of the tower will be investigated. It was concluded that amongst all mentioned parameters, the droplet diameter has the most impact upon decreasing the output temperature of the cooling tower. By changing geometrical parameters(tower height increase and droplet diameter reduction), the outlet temperature of the SCT in different ambient condition could be improved. these towers have high efficiency in dry-cool and dry-hot regions.
