A replica model of PA Hilton H893 cooling tower was fabricated for experimentation. 2 types of decks were also fabricated, one with nozzles at the end of every packing and the other resembling the decks of a conventional H893 cooling tower. Experimental trials were done at a fixed air flow rate and water flow rate, to observe the effect due to addition of nozzles. In this paper, we shall see the procedure and result of the above-mentioned experiment. Further methods of increasing the cooling effect have also been discussed.

Key Words:

Air Flow Rate, Effectiveness, Heat Transfer, Nozzle Effect, Relative Percentage Increase
