Effect Air Flow Rate on the Performance of Perforated Splash Fill Plate of Forced Draft Wet Cooling Tower

A wet cooling tower is an apparatus for transferring heat and mass that directly links hot water and air movement. Because the wet cooling tower provides a large surface area for heat and mass transfer, fill is essential to the tower. This study uses experiments to investigate the performance of a multi-level inclined perforated splash fill in a forced wet cooling tower (WTC). The packing has a 2.6%, 3%, and 3.6% perforation ratio and an inclination angle of 15 degrees, with five layers of galvanized plate fill. The hot water temperature is adjusted to 60 degrees Celsius. The airflow rate varies five times: 0.02033, 0.02631, 0.02995, 0.03770, and 0.04261 kg/s. The water flow rate is ± 0.0917 kg/s. The hot water at the inflow is 60 degrees Celsius. The findings of this study indicate that the cooling efficiency of cooling towers may be significantly improved by raising the mass airflow rate and adopting the suitable perforation ratio.
