Abstract:

In dry climates, evaporative cooling techniques are frequently used in place of air-conditioners to increase energy efficiency and reduce installation costs. An evaporative nozzle is a type of evaporative cooling technique. Evaporative nozzle spraying is a technique that is used in a variety of applications, including cooling and humidification. The performance of evaporative spray nozzles with a number ranging from 2 to 8 nozzles has been examined in terms of nozzle combinations, orientations (horizontal and vertical), and Reynolds numbers ranging from 13000 to 83000. In general, the results show that relative humidity is inversely proportional to the Reynolds number. Furthermore, the nozzle numbers are proportional to the relative humidity. As the number of nozzles in a vertical arrangement increases from 2 to 8, the relative humidity rises to 90%. For 8 spray nozzles, the vertical arrangement produces 7.4% higher outlet relative humidity than the horizontal arrangement. The current investigation’s highest relative humidity is 90%, which occurs for 8 nozzles in the vertical direction at Reynolds number 13300. Moreover, the horizontal and vertical correlations were developed to predict the outlet relative humidity with respect to the nozzle orientation.
