3742 (RP-725) -- Characteristic Study of Sprayed FLuid Flow in a Tube Bundle PDF

The characteristics of fluid flow in a tube bundle subjected to water sprayed from overhead nozzles were studied. Two effects on the performance of liquid distribution were investigated. The tube surface geometry effect and the tube bundle pattern effect. The tube surface geometries tested were plain, low-finned, and grooved. The bundle patterns tested were square pitch and triangular pitch. The characteristics of fluid flow are discussed based on the local liquid flow rates measured using a collector and a stop-watch.
