  • Traveling to Africa: An Orientation

    Creator:
    Converse, Bradley R.
    Abstract:
    After traveling to Africa and experiencing the struggles and confusion of interacting with a new culture, I saw the need for some sort of orientation device that would adequately prepare first timers, but also not be too lengthy and daunting for a person that will only be spending a few...

  • Optimization of Pulsed Laser Deposited Piezoelectric Thin Films for Microelectromechanical Systems

    Creator:
    Kearney, Dylan R.
    Abstract:
    Lead zirconate titanate (PZT) is well known to exhibit some of the strongest piezoelectric responses, explaining why it is at the heart of piezoelectric-based microelectromechanical systems (MEMS) research. The use of pulsed laser deposition (PLD) to synthesize PZT offers many advantages over alternative deposition techniques, mainly regarding its ability to...

  • 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...

  • Life cycle analysis of mass timber and reinforced concrete three-story structures

    Creator:
    Brown, David
    Abstract:
    With growing awareness of the negative impacts of the built environment, solutions for dramatic environmental, economic, and social improvements are sparking in all sectors, especially within the construction industry. The work of this thesis aims to quantify and compare social, economic, and environmental impacts of a three-story mass timber structure...

  • Identification of Barriers to Industrial Energy Efficiency Improvement in the Pacific Northwest

    Creator:
    Martz, Allison M.
    Abstract:
    The US industrial sector accounts for about one-third of the nation’s energy consumption and is predicted to grow twice as quickly as other sectors through 2050. International organizations such as the International Energy Agency project energy efficiency improvements will account for over 40% of greenhouse gas emissions reductions through 2040....

  • 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...

  • Turning Brake Cylinder Housing

    Creator:
    Radcliffe, Noah
    Abstract:
    The purpose of this project is to assist the OSU Baja Racing vehicle in turning more sharply. This is done using a turning brake, which locks one rear wheel to facilitate turning on a smaller radius. This project focuses on the development of a custom cylinder housing for the turning...

  • 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...

  • Trailing Edge Flap Optimization for an Upper-Surface Blown Aircraft Wing

    Creator:
    Kelly, Bryan R.
    Abstract:
    Integrated Distributed Electric Augmented Lift (IDEAL) applies upper surface blowing in a novel way to achieve electric short take-off and landing to meet the growing need for urban air transportation. Additional research on propulsion airframe interaction (PAI) with trailing edge flaps at low Reynolds numbers was necessary to advance the...
