OPTIMIZATION AND CFD ANALYSIS OF INDUCED DRAFT COUNTER FLOW WET COOLING TOWER

Abstract

Cooling towers are one of the biggest heat and mass transfer devices used to transfer process waste heat to
the atmosphere. Cooling towers make use of evaporation whereby some of the water is evaporated into a moving air
stream and subsequently discharged into the atmosphere. As a result, the remainder of the water is cooled down
significantly.
The process parameters such as inlet air rate, water flow rate and fills porosity have more influence on Thermal
performance of cooling tower. The Temperature of outlet water is maintained nearest to inlet air wet bulb temperature to
obtain the best Thermal Performance of cooling tower. So current work is to obtain and maintaining outlet water
Temperature nearest to inlet air wet bulb temperature.
Three different models are made in Creo software and CFX analysis is carried out in ANSYS 12.1.Portable Minitab 16.1
software is used for Taguchi analysis. Result obtained from the taguchi analysis shows that which combination of design
parameter gives the minimum temperature of outlet hot water. The exercise has been carried out at Hariom Metal cast
pvt. At Kathwada GIDC, Ahmedabad.
