  • On the effects of centrifugal forces in air-water two-phase flow regime transitions of an adiabatic helical geometry

    Creator:
    Young, Eric P.
    Abstract:
    Two-phase flow in helical conduits is important in many industries where reaction between components, heat transfer, and mass transport are utilized as processes. The helical design is chosen for the effects of secondary flow patterns that reduce axial dispersion, increased heat transfer, and also their compact design. The first is...

  • A general theory of flooding implementing the cuspoid catastrophe

    Creator:
    Lafi, Abd Y.
    Abstract:
    The flooding phenomenon can be defined as the maximum attainable flow condition beyond which the well defined countercurrent flow pattern can no longer exist. Thus the countercurrent flow limit (CCFL) or the flooding limit may be thought of as the flow condition at which the strong interaction between the two...

  • A study of return to saturation oscillations in the OSU APEX thermal hydraulic testing facility

    Creator:
    Franz, Scott C.
    Abstract:
    The purpose of this paper is to describe the flow oscillations which occur in the AP600 long term cooling test facility at Oregon State University. The AP600 system is an advanced pressurized water reactor design utilizing passive emergency cooling systems. A few hours after the initiation of a cold leg...

  • An on-line advanced plant simulator (OLAPS)

    Creator:
    Samuels, Jeffery W.
    Abstract:
    A PC based on-line advanced plant simulator (OLAPS) for high quality simulations of Portland General Electric's Trojan Nuclear Facility is presented. OLAPS is designed to simulate the thermal-hydraulics of the primary system including core, steam generators, pumps, piping and pressurizer. The simulations are based on a five equation model that...

  • Ultrafiltration of fruit juice and wine

    Creator:
    Flores Gaytan, Jose Humberto
    Abstract:
    The possible effect of oxidation [processing with or without sulfur dioxide (±S0₂)] and of pre-ultrafiltration treatment of juices with enzymes and fining agents on flux, and on juice color, composition and stability was investigated. White Riesling juice was ultrafiltered with a Romicon system operated with a nominal molecular weight cut-off...

  • Carbene rearrangements : intramolecular interaction of a triple bond with a carbene center

    Creator:
    Dan̄ino, José C.
    Abstract:
    The tosylhydrazones of 2-heptanone, 4,4-dimethy1-2- heptanone, 6-heptyn-2-one and 4,4-dimethy1-6-heptyn-2- one were synthesized and decomposed under a variety of reaction conditions: dry lithium and sodium salt pyrolyses, sodium methoxide thermolyses in diglyme and photolyses of the lithium salt in tetrahydrofuran. The saturated analogues 2-heptanone tosylhydrazone and its 4,4-dimethyl isomer afforded the...

  • Performance and stability analysis of gas-injection enhanced natural circulation in heavy-liquid-metal-cooled systems

    Creator:
    Yoo, Yeon-Jong
    Abstract:
    The purpose of this study is to investigate the performance and stability of the gas-injection enhanced natural circulation in heavy-liquid-metal-cooled systems. The target system is STAR-LM, which is a 400-MWt-class advanced lead-cooled fast reactor under development by Argonne National Laboratory and Oregon State University. The primary loop of STAR-LM relies...

    Abstract:
    Influence of abiotic and biotic factors were examined in selected winter wheats previously identified as representing a range of responses to septoria infection. In the greenhouse two and three inoculations identified resistance when disease severity was assessed either for the top four leaves or the flag leaf respectively. Kernel number...

    Abstract:
    The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...

    Creator:
    Suchite, Jose M.
    Abstract:
    Little research has been done in the area of adult Hispanics' transition to college, a complex and challenging process which marks a critical period in their lives. Research suggests adaptation difficulty may cause them to drop out of school usually before completion of the first terms. There is a lack...
