Abstract:: This paper describes a study of two-phase gas-liquid vertical annular climbing film flow. Using a high speed Fastax movie camera, motion was slowed sufficiently to facilitate detailed analysis of the climbing film structure, based on single frame projections. The dynamic characteristics of the liquid film could likewise be obtained, though...

Abstract:: Friction factors were measured for water flowing in ducts made up of two rods held between two flat plates. Three rod diameters of 0.50, 1.00 and 1.50 inches were used. The spacings between rods varied from 0.0 to 0.32 inch. It was found that the concept of hydraulic diameter was...

Abstract:: The fouling characteristics of cooling tower water containing various corrosion inhibitors and other additives on heat transfer surface have been investigated. Corrosion inhibitors investigated included zinc-chromate and phosphates. In addition, additives including polyacrylate and phosphonate (HEDP and AMP) were used to determine their effectiveness as antifoulants. The tests were conducted...

Abstract:: The fouling characteristics of simulated cooling tower water flowing over a heated metallic surface has been studied. The bulk temperature of the water was maintained around 95°F. Mainly three different water qualities with respect to calcium hardness level were investigated. The pH was controlled by the addition of hydrochloric acid....

Abstract:: Scaling characteristics of calcium carbonate on a heated surface in cooling tower water was investigated. Bulk temperature was maintained constant at 95°F. Flow velocities and surface temperatures ranged from 3 ft/sec to 10.3 ft/sec and from 105°F to 170°F respectively. City water was used as make-up for two different water...
