Effect of Wind Directions on the Thermal Performance of Three Aligned NDDCT: Parallel and Perpendicular Directions

Abstract:

Article Preview

In this paper a 3-D numerical model is used to investigate the thermal performance of a three aligned unit of NDDCT under crosswind condition. The computed results show that, there are major differences in computed velocity patterns and pressure fields around the cooling tower due to neighboring of a number of cooling towers will result considerable changes in computed flow parameters hence; the thermal performance losses for the single tower under crosswind are superior to those when this towers are incorporated in aligned arrangement. Results also show that the best thermal performance of the three aligned NDDCT is achieved when the crosswind is directed along the towers connection line.
