  • Experimental study of subcooled water spray cooling using flow symmetric micro-structured surfaces

    Creator:
    Tulchinsky, Alex M.
    Abstract:
    Spray impingement cooling has been shown to be a leading candidate for future high heat flux cooling applications. In general, spray cooling curves consist of three heat flux regimes; single-phase, two-phase and critical heat flux (CHF). CHF is considered the design limit for almost all two-phase cooling applications, as a...

  • Local heat transfer rate and bubble dynamics during jet impingement boiling

    Creator:
    Mani, Preeti
    Abstract:
    Characterization of local boiling trends, in addition to the typically reported area-averaged trends, is essential for the robust design and implementation of phase change technologies to sensitive heat transfer applications such as electronics cooling. Obtaining the values of heat fluxes corresponding to locally varying surface temperatures has been a challenge...

  • Performance and flow stability characteristics in two-phase confined impinging jets

    Creator:
    Sabo, Michael D.
    Abstract:
    Advances in electronics fabrication, coupled with the demand for increased computing power, have driven the demand for innovative cooling solutions to dissipate waste heat generated by these devices. To meet future demands, research and development has focused on robust and stable two-phase heat transfer devices. A confined impinging jet is...

  • Submerged jet impingement boiling thermal management

    Creator:
    Cardenas, Ruander
    Abstract:
    Technologies such as avionics and power electronics are driving the demand for thermal management schemes towards high heat fluxes and low surface temperatures. Typically, these applications require the dissipation of heat fluxes in the rage of 100-1000 W/cm² while maintaining surface temperatures lower than about 85 °C. Phase-change heat transfer...

  • A mathematical method of evaluating the reliability of electronic equipment

    Creator:
    Lindquist, Claude S.
    Abstract:
    Reliability, the probability that a system will not fail but will perform correctly at least until some arbitrary time, is becoming an increasingly important concept in electronic system design. This probability is evaluated using probability density functions which are obtained analytically by forming mathematical expressions describing the failure distributions of...

  • Micro adiabatic combustion engine : concept development, simulation and combustion experiments

    Creator:
    Chewning, Scott R.
    Abstract:
    The current proliferation of portable electronic devices for personal communication, business and entertainment has created a demand for high energy density power supplies. A hydrocarbon fuel with a conversion efficiency of over 15% can provide greater energy density than current battery technology for these applications. Current micro-scale heat engines do...

  • Development, fabrication, and characterization of transparent electronic devices

    Creator:
    Hoffman, Randy L.
    Abstract:
    The objective of this thesis is to provide an initial demonstration of the feasibility of constructing highly transparent active electronic devices. Such a demonstration is successfully achieved in the fabrication of ZnO-based thin film transistors (TFTs) exhibiting transparency greater than ~90% in the visible portion of the electromagnetic spectrum and...
