  • 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...

  • Reliability Analysis of a Freeze Desalination System

    Creator:
    Boschetti Tofano, Francisco A.
    Abstract:
    The unsustainable use of fresh water sources and unavailability of fresh water in certain parts of the world have created a demand for water desalination systems. Desalination methods are effective at producing consumable water, but often require large scale setups, high energy consumption, and careful maintenance. A team of students...

  • Computational Modeling of Smoldering Combustion in Wildland Fuels

    Creator:
    Jayasuriya, Waduge Jayani A.
    Abstract:
    Smoldering combustion in wildland fires is a critical phenomenon that needs in-depth study because it can initiate with weaker ignition sources, can persist for long periods, is difficult to suppress, and can transit to flaming combustion. Cellulose, hemicellulose, and lignin are the major organic constituents within biomass, in varying proportions...

  • A Field Study on Marching Band Members' Workload Assessment

    Creator:
    Wells, Robyn R.
    Abstract:
    Marching band activities consist of both physically and cognitively demanding tasks. The demands that this activity has on players has largely been unstudied. The goal of this study was to investigate the effects of players’ experience level, role, and gender on the workload of marching band players via a field...

  • The Design of a High-Vacuum Chamber Testing Environment

    Creator:
    Robinson, Kimbert J.
    Abstract:
    The intention of this undergraduate research project was to design and build a fully functional high-vacuum chamber testing environment for use in the development of ion propulsion engines. This project was conducted in an effort to aid ongoing projects between the Deep Space Propulsion Group (DSPG) at Oregon State University...

  • Investigation and Implementation of a Liquid Feeding System for the Apis mellifera Honey bee under Laboratory Conditions

    Creator:
    Meador, Brett W.
    Abstract:
    Studying honey bee behavior is a very important aspect of horticulture, especially in recent years as honey bee colonies face population decline, or colony collapse. While studying honey bees, researchers often keep honey bees in captivity, where it can be challenging to meet nutritional and hydration requirements using existing liquid...

  • Selective Laser Melting of H13 Tool Steel for Rapid Tooling

    Creator:
    Katancik, Michael
    Abstract:
    The current knowledge on the microstructural evolutions and mechanical properties of selective laser melting (SLM) produced H13 tool steel components is limited. This research is focused on optimization of SLM processing parameters for H13 tool steel and investigation of microstructure and mechanical properties of H13 tool steel components after SLM...

  • Temperature Evolution of Nonreacting Spark Kernels at Sub-Atmospheric Pressures

    Creator:
    Caplan, Daniel L.
    Abstract:
    In the event of a mid-flight flameout of a gas turbine engine, reignition is paramount to occupant safety. Ignition at high altitude can be challenging, due in part to the potentially lower ambient pressures. An understanding of the effects of sub-atmospheric pressures on the temperature evolution of spark kernels is...

  • Melting Stage Analysis for Indirect Freeze Desalination

    Creator:
    Pratt, Mason G.
    Abstract:
    To investigate the melting stage of indirect freeze desalination three numerical models were developed. A zeroth, first, and second order analyses modeled the melting of ice around the outside of a pipe as a function of time. The zeroth order analysis assumes the system to be steady state. The first...

  • Comparison of the Accuracy and Applicability of Forebody Wake Effect Models for Parachute System Design

    Creator:
    Kemling, Gabriel H. and Blunck, David L.
    Abstract:
    The forebody wake effect (FWE) is important to consider when designing parachute systems because it can affect parachute performance. Parachutes work by altering the aerodynamic properties of an attached forebody to control a descent. The FWE can reduce parachute drag, causing the system to descend faster than desired. This drag...
