  • Large-strain softening of aluminum in shear at elevated temperature

    Creator:
    Alhajeri, Saleh N.
    Abstract:
    Pure aluminum deformed in torsion (shear) at elevated temperatures reaches a broad "peak" stress and then undergoes about a 17% decrease in flow stress with deformation to roughly 1-2 equivalent uniaxial strain. Beyond this strain the flow stress is approximately constant. The sources for this softening are unclear. The suggested...

  • Thermal characterization technique for thin dielectric films

    Creator:
    Indermuehle, Scott W.
    Abstract:
    A phase sensitive measurement technique that permits the simultaneous determination of two independent thermal properties of thin dielectric films is presented. Applying the technique results in a film's thermal diffusivity and effusivity, from which the thermal conductivity and specific heat can be calculated. The technique involves measuring a specimen's front...

  • Thermal contact resistances in a thermal conductivity test system

    Creator:
    Schneider, Donald A.
    Abstract:
    The thermal contact conductance (TCC) between two machined pieces of stainless steel was studied. A guarded hot plate thermal conductivity test fixture was designed and built for the experiment. Factors investigated included the contact pressure, surface roughness, interface material and average test temperature. The contact pressure at the interface ranged...

  • Temperature measurement, electrical characteristics, and lorentz mixing of alkali seeded flames

    Creator:
    Pattee, Heidi Ann
    Abstract:
    When trace quantities of an alkali element are added to a flame, its optical and electrical properties change significantly. Addition of alkali seed to both premixed and diffusion flames has been used in the development of two new techniques, one for flame temperature measurement and the other for enhanced mixing....

  • Transient fuel pin temperature calculations using describing functions

    Creator:
    Guidotti, Timothy E.
    Abstract:
    An important element in rector safety and fuel performance assessments is the efficient calculation of the time dependent temperature profiles within reactor fuel pins. Because the fuel pins have temperature dependent thermal properties, the governing partial differential equations are nonlinear. Traditionally, finite difference or finite element methods have been used...

  • Modeling the thermal inkjet firing process

    Creator:
    Davis, Colin C.
    Abstract:
    A numerical model has been developed to simulate the firing of an inkjet printhead. The model evaluates the heat generation and diffusion within the thin film structure, the phase change and vapor bubble growth in the ink, and the subsequent flow of ink from the orifice. The heat transfer is...

  • Constrained thin film desorption through membrane separation

    Creator:
    Thorud, Johnathan D.
    Abstract:
    A constrained thin film desorption scheme has been experimentally tested to determine the desorption rates for water from an aqueous lithium bromide mixture through a confining membrane. Variable conditions include the inlet concentration, pressure differential across the membrane, and channel height. Desorption takes place in a channel created between two...

  • Modeling of geothermal power plants using the binary fluid cycle

    Creator:
    Walter, Ronald A.
    Abstract:
    In light of the current world-wide energy situation, the utilization of the immense reserves of geothermal energy is being actively pursued. The thermal energy contained in a geothermal reservoir is mainly stored in rocks, but is also held in liquid water and/or steam. The generation of electrical power from these...

  • Composite and adhesive technology applied to chain saw guide bars

    Creator:
    Gabel, Preston S.
    Abstract:
    Increased competition in the market place for both occasional and professional chain saw users has led to a desire for improved performance in chain saw guide bars. One aspect of improved performance is lower bar weight. The primary focus of this research was to establish the feasibility of a lower...
