Motion picture study of a vertical climbing film in an annular duct

Creator:

Scott, Bruce Douglas

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...

Deposition characteristics of magnesium silicate and calcium carbonate in cooling tower water

Creator:

Lee, Sai Heep

Abstract:

Deposition characteristics of magnesium silicate and calcium carbonate on a heated surface in cooling tower water using city water as make-up was investigated. Flow velocity, bulk temperature and calcium hardness were maintained constant at 5.3 ft/ sec, 95°F and 150 ppm as CaCO₃ respectively whereas surface temperature varied from 105°F...

Calcium carbonate scaling characteristics of cooling tower water

Creator:

Coates, Kenneth Edwin

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...

Fouling characteristics of cooling tower water : pH effect

Creator:

Roy, Bhasker Vilva

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....

Effects of water quality and surface temperature on the scaling characteristics of cooling tower water

Creator:

Lahm, Lawrence

Abstract:

The fouling of cooling tower water was investigated as a function of heater surface temperature and water quality. In particular, the effects on fouling of the addition of calcium in excess of the amounts required for saturation were examined. First, the average bulk water temperature was 97 ± 1 degree...
