Nozzle-sprayed flow rate distribution on a horizontal tube bundle.

Author(s) : CHYU M. C., ZENG X., AYUB Z. H.

Summary

An analysis of spray flow rates from nozzles reaching horizontal tubes at different locations below is presented. Such flow rates dominate the heat transfer performance of a device including spray nozzles and a tube bundle. The flow rates are predicted based on a given total nozzle flow rate, nozzle height, nozzle interval, spray angle, tube diameter, and the horizontal distance between the tube and the nozzle. The result is applicable to single-row as well as array nozzle arrangements. Both round and square full-cone nozzles were considered. The analysis compares favorably with the nozzle-sprayed ammonia and water flow rate experimental results.
