EXPERIMENTAL INVESTIGATION OF AIR SIDE PRESSURE LOSS FOR WET-COOLING TOWER FILLS

ABSTRACT
The pressure loss of air-flow in the cooling tower was measured experimentally with three different type cooling tower fill materials. Air mass flux (3.13 < Ga , < 5.21 kg/m2s), water mass flux (2.43 < Gw , < 5.21 kg/m2s) and height of the fill material (0.6, 0.8, and 1 m) were used as variable parameters for experimental works. Film, curler and splash type fillings were tested in the forced draft counter flow cooling tower unit which has 0.4 × 0.4 m2 cross-section area. Experimental results were presented graphically. However, these results correlated for each type cooling tower fill material. The pressure loss was increased with increasing air mass flux. The pressure loss of film type filling is 29.1% higher than splash type.
