Fluid Dynamics to analyze the flow passing through a Cooling Tower: A Study
Keywords:
Computational Fluid Dynamics (CFD), Cooling Power, Droplets, TemperatureAbstract
A cooling tower is a crucial component in power plants and heating ventilation air conditioning systems. It functions by expelling waste heat from hot water into the environment. As the hot water interacts with the air, it undergoes sensible heat transfer and the vaporization of certain water droplets, resulting in a decrease in water temperature. The analysis of the results indicates that as the droplet diameter decreases in any given height of the rain zone, there is an increase in the temperature drop. Furthermore, it is observed that the rate of temperature decrease is higher for the rain zone at a height of 8.577 m compared to the other two rain zones.
