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...

Turbulent mixing across adjacent subchannels in packed rod bundles using conductivity measurement

Creator:: Chan, Pui Yuen
Abstract:: Turbulent mixing across adjacent subchannels in packed rod bundles was studied using conductivity measurement and sodium chloride solution as the tracer. Single phase water was the fluid investigated. The packed rod bundles were seven stainless steel tubes, 1.905 cm in diameter and 152.4 cm long, arranged in hexagonal close-packed configuration...

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...

Local and average heat transfer coefficients in a fluidized bad heat exchanger

Creator:: Noe, Alphonse Roman
Abstract:: Local and average heat transfer coefficients for heat transfer from internal tubes to a fluidized bed were investigated. A fluidized bed heat exchanger was compared to a baffled and an unbaffled exchanger in terms of power and heat transfer surface area requirements. The fluidized bed heat exchanger consisted of a...

Natural and forced turbulent mixing in rod bundles

Creator:: Jovanovic, Goran N.
Abstract:: The effects of mass flow rate and subchannel configuration on the turbulent interchange between adjacent subchannel in simulated rod bundle were investigated. The simulated rod bundle was made by arranging seven 1.913 cm diameter acrylic plastic rods in an equilateral triangular pattern in a tube 8.89 cm inside diameter. The...

The effect of copolymer and iron on the fouling characteristics of cooling tower water containing corrosion inhibitors

Creator:: Abu-Al-Saud, Abdullah A.
Abstract:: Various antifoulant treatment programs and the considerations necessary for the effective use of such programs were examined. Two different groups of tests, with and without iron contamination, have been carried out on the effectiveness of several of the state-of-the-art copolymers (PA, HEDP, AA/HPA, AA/MA, SS/MA and AA/SA) in the inhibition...
