  • Cryogenic Single-Phase Heat Transfer in a Microscale Pin Fin Heat Sink

    Creator:
    Truong, Eric D.
    Abstract:
    A combined experimental and computational fluid dynamics (CFD) study of single-phase liquid nitrogen flow through a microscale pin-fin heat sink is presented. Such cryogenic heat sinks could find use in applications such as high performance computing, spacecraft thermal management, and hydrogen storage thermal management. A circular pin fin heat sink...

  • Experimental Design Approach for Evaluation of Airfoil-Driven Energy Harvesting

    Creator:
    Strahl, Jordan D.
    Abstract:
    An experimental setup has been partially developed to investigate the impact of an actively controlled trailing edge component upon the energy harvesting performance of an oscillating airfoil in a pitching and heaving regime. While previous and current efforts have and continue to function to characterize the performance of such a...

  • The Influence of Gas Extraction on Bubble Dynamics

    Creator:
    Juarez, Corey D.
    Abstract:
    A new thermal management method for hotspots on microprocessors is under development that employs confined pool boiling with vapor extraction at pre-determined nucleation sites. Extraction is accomplished by locating a vacuum chamber constructed out of a glass tube and a hydrophobic membrane directly above a nucleation site. In order to...

  • Automated Trunk Diameter Measurement

    Creator:
    Sankari, Pico
    Abstract:
    This thesis describes an automated method to estimate tree trunk width in a commer-cial apple orchard. Trunk cross sectional area, which is an important consideration with regards to nutrient uptake, is a feature being integrated in a decision support system for precision Nitrogen management. The data used to generate the...

  • Design and Testing of a Tethered, Coaxial Rotor Micro Air Vehicle

    Creator:
    Shryer, Jacob R.
    Abstract:
    Unmanned Aerial System (UAS) technology is a rapidly developing technological marketspace. This thesis focuses on micro, tethered, coaxial UASs and the development of an electrically-tethered observation platform (ETOP). The thesis details the current status of the technology as well as current products on the market. Stability considerations, critical when adding...

  • Phase Separation in Microscale Convective Boiling

    Creator:
    Lewis, Kevin Terrence
    Abstract:
    It is hypothesized that extracting the vapor from two-phase flow in a microchannel will result in a lowered pressure drop required to drive the flow. The goal of this thesis is to construct an experimental device that will test this hypothesis by comparing a number of phase separating test conditions...

  • TO PAY OR NOT TO PAY, THAT IS THE QUESTION

    Creator:
    Oster, Sidney C.
    Abstract:
    The “why” of any situation is one of the most important questions to ask. Inventors have ideas every day. Some ideas are the brilliant ideas that lead to a better tomorrow. To protect these ideas, inventors turn to patents, a governmental grant of the right to stop others, for a...

  • Effects of thermal stressing on the turbulent flame speed of jet fuel

    Creator:
    Alkhalifa, Ammar M.
    Abstract:
    Gas turbine engines for propulsion applications can use fuel as a coolant, exposing the fuel to high temperatures well within the ranges associated with thermal decomposition. Species produced as a result of these processes have been shown to correlate with changes in the combustion performance of the fuels. In this...

  • Effects of Dilution on Turbulent Consumption Speeds of Jet Fuel

    Creator:
    Walters, Ian
    Abstract:
    Combustion systems for transportation applications typically use large hydrocarbon fuels in turbulent premixed or partially premixed environments. Combustion products can enter the reaction region through natural recirculation or combustion control mechanisms. The objective of this study is to characterize how dilution by combustion products affects the turbulent consumption speed for...

  • Effects of nickel addition In Cu-Zr-Hf-Al metallic glass matrix

    Creator:
    Miska, John
    Abstract:
    Metallic glasses (also referred to as amorphous metals) have been gaining interest in the materials science community in recent years. These amorphous materials demonstrate promising properties compared to their crystalline counterparts that include much higher strength and elastic strain limit, better corrosion and wear resistance, superior soft magnetism, and an...
