STUDY ON COOLING TOWER GEOMETRY MODIFICATION FOR PERFORMANCE IMPROVEMENT USING ANSYS FLUENT AND ANSYS DISCOVERY LIVE SOFTWARE
As one of the systems in a power plant, the cooling tower should always operate optimally according to its design conditions. But over time, the cooling tower performance has decreased. If there is a decrease in cooling tower performance, of course, it will be bad for the whole power plant system...

Summary: | As one of the systems in a power plant, the cooling tower should always operate
optimally according to its design conditions. But over time, the cooling tower performance
has decreased. If there is a decrease in cooling tower performance, of course, it will be bad
for the whole power plant system.
Evaluation of cooling tower performance is needed to find out how much
deterioration in cooling tower performance after operating for decades. The method used in
evaluating cooling tower performance is the performance curve method and the characteristic
curve method found in the ATC-105 CTI. The effectiveness value method is also used in
evaluating cooling tower performance in terms of effectiveness value. Based on the
performance curve method, the capability value has decreased from 107,49% to 70.06 %.
Then, based on the characteristic curve method the capability value has decreased from
113,84 % to 69,11 %. Finally, based on the effectiveness value method, the cooling tower
effectiveness value has decreased from 69,2 % to 60,95 %.
Geometry modification is done to improve cooling tower performance. With the
modification, the airflow rate in the cooling tower has increased from 627,74 kg/s to 665,61
kg/s. The increase in airflow rate causes a decrease in the temperature of the water exiting
the cooling tower from 30 °C to 29,6 °C. In the end, the decrease in the temperature of the
water coming out of the cooling tower can improve the cooling tower performance in terms
of the effectiveness value from 60,95 % to 62,17 %.
