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...

Creator:: Obuskovic, Nevenka S.
Abstract:: Heat transfer to moving packed beds of solids has been studied extensively but predictions are usually specific to the experimenter's own equipment. In order to obtain a more general predictive equation, the heat transfer coefficient was measured for a single vertical tube immersed in a moving packed bed of glass...

Creator:: Imdakm, Abdussalam Omar
Abstract:: Various conditions of heat flux in the range of 46600 to 93300 Btu/hr ft² and water velocity in the range of 1.44 to 2.16 ft/sec were tested under carefully controlled conditions to determine their effect on scale formation, and the characteristics of scale. Inlet temperature and bulk temperature were maintained...

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...

Creator:: Cates, David Lawrence
Abstract:: A bench-scale thermosiphon reboiler system was constructed end used to investigate the scaling behavior of aqueous calcium sulfate under flow boiling conditions. Scaling data were collected at constant heat flux from eight experimental runs. Five different constant heat fluxes were used ranging from 45000 to 93000 Btu/hr. ft², in increments...
