  • Geometric and wall pressure characterization of patient abdominal aortic aneurysm

    Creator:
    Aslani, Elham
    Abstract:
    In this study, we have characterized a series of patient Abdominal Aortic Aneurysms (AAAs) based on their geometric parameters, wall pressure distributions and ages. Abdominal aortic aneurysms (AAAs) are localized aortic dilations that have been estimated to occur in 5 to 7 percent of the U.S. population over age 60....

  • Measuring and modeling solids movement in a large, cold fluidized-bed test facility

    Creator:
    Daous, Muhammad A.
    Abstract:
    Solids movement in large-particle fluidized beds was studied in an 18 in x 18 in (46 cm x 46 cm) tube-filled, cold fluidized bed test facility. Direct measurement of local solid mass flux in two dimensions at various locations inside the bed was made possible by a new instrument developed...

  • A liquid sulfur dioxide battery

    Creator:
    Schaer, Michael Jon
    Abstract:
    A liquid sulfur dioxide battery, such as K/KCl SbCl₅ (0.25 molar) + IBr₃ (15 %wt) + SO₂ (1)/carbon matrix is shown to have an open circuit voltage greater than 3.70 volts and an initial voltage of 3.15 volts, decreasing to 2.40 volts in 10 minutes at a current density of...

  • Automation of a low-temperature calorimeter

    Creator:
    Beyer, R. P. (Richard P.)
    Abstract:
    An adiabatic calorimeter operating over the range 5 to 300 K has been automated. Instrumentation includes computer controlled data acquisition, a low-thermal emf multiplexer for switching low-level dc signals, and automatic analog shield controls. Temperature measurements are made with platinum and germanium resistance thermometers, and the thermometer resistances are determined...

  • Thermally activated electrochemical cells using a stabilized zirconia electrolyte

    Creator:
    Clark, Dwight Pocock
    Abstract:
    The performance of solid metallic anodes on a solid electrolyte was determined experimentally and data on cell current, cell voltage, open-circuit cell potential, and cell energy are presented. Fifteen-mole percent calcia-stabilized zirconia was used as the electrolyte, a platinum-oxygen electrode was used as the cathode, and 1000° C was 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...

  • Calcium carbonate scaling in a deluged dry cooling system

    Creator:
    Barton, Kathleen Patricia
    Abstract:
    Scaling characteristics of calcium carbonate on a heated surface in a deluged dry cooling system were investigated. Bulk temperature of the deluge water was maintained constant at 90°F. Air flow velocity was maintained constant at 181 cfm., and deluge water flow was maintained at the minimum level that provided thorough...

  • A study of carbon anode polarization in fused carbonate fuel cells

    Creator:
    Hauser, Victor Emerald
    Abstract:
    The graphite anode reaction in a fused carbonate electrolyte is studied theoretically and experimentally. Data on open circuit cell potentials indicate, for operation below 900°C, only a small fraction of the free energy of reaction is converted to electrical work. Anode polarization measurements were made for current densities of up...

  • 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...
