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 inair conditioning 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, with particular interest in radial windbreakers methods around towers. The study explores a realistic scenario with four cooling towersin-square arrangement. A power plant cooling towers performance has been modeled numerically for a special order of radial wind breakers. Efficiency improvement is obtained for each of the towers and the results are compared.
