Optimization of Wind Breakers Length

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 air 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 wind breakers methods 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 for different lengths of wind breakers to find the best condition. Efficiency improvement is accomplished for different lengths, the results are compared and the optimized length is introduced.
