چکیده:

Cooling towers are evaporative heat transfer devices in which atmospheric air cools warm water, with direct contact between the water and the air, by evaporating part of the water, mostly used in airconditioning and industrial processes. Cooling efficiency of a natural draft, dry cooling tower(NDDCT) is significantly affected under cross-wind condition. This paper investigates a solution that may improve cooling performance of cooling towers, for four different patterns of wind breakersmethods around towers. The study explores a realistic scenario with four cooling towers in-square arrangement. A power plant cooling towers performance has been modeled numerically. Efficiency improvement is obtained for each of the towers and the results are compared. The best pattern is introduced to be applied in the project
