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....

Momentum transfer in climbing-film flow in an annular duct

Creator:: Kim, Duk Hwang
Abstract:: Momentum transfer in an annular duct with upward gas-Iiquid flow was studied under the condition that the liquid flowed as a film only on the inner core of the annulus, the outer wall remaining dry. Previous workers have studied climbing and falling liquid films in tubes or on vertical planes....

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...

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...

Drop size distributions produced by turbulent pipe flow of immiscible liquids

Creator:: Collins, Stanley Browning
Abstract:: Drop size distributions produced by the turbulent pipe flow of dispersions of immiscible liquids were measured photographically. A mathematical model was developed which predicted both the shape of the experimentally observed distributions and the experimentally observed kinetics of the breakup process. The mutually saturated water and organic phases were pumped...

Fouling characteristics of cooling tower water containing corrosion inhibitors

Creator:: Santoso, Elisabeth
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...

A study of climbing-film flow characteristics of various liquids and air in an annular duct

Creator:: Vierra, George Joseph
Abstract:: Momentum transfer in climbing-film flow in an annular duct was investigated. Air and various liquids, with a wide range of viscosities and surface tensions, were investigated. The two phases flowed co-currently upward, the liquid climbing as a thin film on the inner wail while the outer wall remained dry. The...

Turbulent heat transfer in annuli at large diameter ratios

Creator:: Unzicker, William Frank
Abstract:: Heat transfer from the inner wall of an annulus to subcooled water in turbulent parallel flow was studied. The inner core of the annulus consisted of wires varying from 0.0019 to 0.0197 inch in diameter. The outer tube consisted of a 1.01 inch diameter glass tube 24 inches long. Diameter...
