  • Modeling hop kilning with respect to energy consumption and drying kinetics

    Creator:
    Thomas, Matthew W.
    Abstract:
    Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...

  • 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...

  • Multi-Scale Study of Ember Production and Transport under Multiple Environmental and Fuel Conditions

    Creator:
    Hudson, Tyler R.
    Abstract:
    Spot fires caused by lofted embers (i.e., firebrands) can be a significant factor in the spread of wildland fires. Embers can be especially dangerous near the wildland-urban interface (WUI) because of the potential for the fire to be spread near or on structures. Many studies have investigated the transport of...

  • Ergonomic Analysis of the Global Formula Racing Driver Interface

    Creator:
    Davis, Sean M.
    Abstract:
    Between Oregon State University and DHBW Ravensberg, Global Formula Racing produces two Formula style vehicles every year for competition. This thesis has served as a pre-development project in the ergonomics and driver interface of the team's vehicles. This project will determine the position of the seat back, steering wheel, and...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...
