Experimental and Theoretical Study of Cooling Tower Performance Using Different Types of Packing
الخلاصة

Abstract
This research aims to study and analyze the thermal performance of counter flow cooling tower with three different types of packing , Corrugated plastic sheets, perforated aluminum square channel sheets and finally plastic balls arranged in square matrix .The performance was analyzed theoretically and experimentally through studying the effect of temperature of the heat water entering the cooling tower with different mass flowrate of water and air for the three types of packing .
The results showed that the inlet water temperature to the cooling tower has a great effect on the tower performance .As the temperature increases the performance decreases. In contrast as the air flow rate increases the tower performance increases but to a certain limit.
To investigate the effect of the packing length, three lengths were chosen and a number of correlations equations representing the tower performance factor were derived a computer program was built using Engineering Equation Solver (EES) to simulate finite difference method based on a mathematical model .
The results showed that the highest tower performance was when aluminum packing was used and the lowest when plastic balls were used .
