The objective of this study is to investigate experimentally and theoretically
heat and mass transfer characteristics of the cooling tower. The investigation
carried out at a mechanical forced direct cooling tower. A column-packing unit is
made of a new type of packing named honeycomb (plastic). Air and water are
used as fluids and the runs are done at the air and water mass flow rates ranging
between 0.05 and 0.15 kg/s, and between 0.1 and 0.25 kg/s, respectively. The inlet
water temperatures ranging between 35 and 50 oC. A mathematical model based
on the equations of mass transfer and energy is used and solved to determine the
characteristics of cooling tower, pressure drop, temperature ratio, and tower
effectiveness. There is reasonable agreement from the comparison between the
calculated and measured data.
