  • Friction losses for water flowing in non-circular ducts

    Creator:
    Mohandes, Abdolhosein
    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...

  • 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...

  • A study of two-phase liquid-liquid flow in pipes

    Creator:
    Soot, Peet Mati
    Abstract:
    The pressure drop for two-phase liquid-liquid flow is theoretically predicted for each flow regime. Empirical correlations, which are applicable in all flow regimes, are also presented for holdup as well as pressure drop. The experimental study covered bubble and drop flow regimes. The discontinuous phase was injected by nozzle into...

  • Fouling characteristics of a desalted crude oil

    Creator:
    Lin, Dah-cheng
    Abstract:
    The fouling characteristics of a desalted crude oil were investigated in a systematic investigation. There are two main parts in this study, the dry bulk tests (dehydrated crude oil) and the wet bulk tests (to which desalter brine was added). Three barrels of desalted crude oil provided by Amoco Oil...

  • 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...

  • 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...

  • 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...

  • 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...
