摘要
Abstract
Based on the spray performance experiments of XPH and TP-Ⅱ nozzles,the water distribution throughout the whole tower affected by different parameters and arrangement of nozzles was analyzed. The results show that the flow coef-ficient of XPH is low and able to apply to the condition where pressure head is larger than 10,kPa. Groups of TP-Ⅱ nozzles should be used to make water well distributed. XPH nozzles should be positioned as an equilateral triangle at the wall zone in the tower. The middle zone full of air should be controlled by TP-Ⅱ nozzles arranged as a square. TP-Ⅱ nozzles distributed as a regular hexagon should be used at the core of the tower to reduce the spraying consistency and investment. The results can provide quantitative references for the optimization of cooling design and transformation.关键词
