  • An Improved Chemical Kinetic Model Reduction in pyMARS for Liquid Propellants

    Creator:
    Moore, Cailin J.
    Abstract:
    The aerospace industry uses chemical kinetic models when designing propulsion systems to acquire specific details about the rate of chemical reactions, heat release, and combustion stability. These models, however, are too large and stiff to be useful as they can take weeks to run computations on. The pyMARS python package...

  • Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

    Creator:
    Bowen, Michael S.
    Abstract:
    Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

  • Design for Clean Technology Adoption: Application of Discrete Choice Analysis and the Theory of Planned Behavior for Development Engineering

    Creator:
    Pakravan, Mohammad H.
    Abstract:
    Clean technologies can address multiple challenges associated with climate change, environmental protection, and human health. However, the impact desired by introduction of such technologies is achievable only if new options effectively replace inefficient, conventional practices. This ‘design for adoption’ requires understanding of user motivations, associated beliefs, context of use, and...

  • Design of 3D-Printed Soft Pneunet Actuator for Robotic Fruit Harvesting

    Creator:
    Wilhelm, Lissette J. H.
    Abstract:
    This work details the development of 3D printed TPU pneunet actuators for use in apple picking for agricultural soft robotics. These actuators increase the force capabilities of soft pneunets and simplify manufacturing. Grippers based on these actuators are ideal for apple picking because they are compliant, yet exert sufficient force...

  • Soot Modeling: GPU Accelerated Direct Simulation Monte Carlo

    Creator:
    Lorson, Paige
    Abstract:
    For this project, we designed a soot modeling software to produce a full particle density function. This model uses the Direct Simulation Monte Carlo with a full conditioning particle selection method to capture soot nucleation and coagulation in a diffusion flame. We investigate the use of graphic processing units as...

  • Simulating Soot Formation and Growth using a Parallel Coupled Monte Carlo Method

    Creator:
    Peters, Jordan
    Abstract:
    Small hydrocarbon particles such as soot and soot precursors pose a serious threat to human health and Earth's climate. Understanding the mechanisms by which soot particles form and grow is the first step to reducing the prevalence of these particles. Computational simulations are used to investigate combusting systems which are...

  • Ignition of Fuel Beds by Firebrands

    Creator:
    Bean, Derek R.
    Abstract:
    The severity of wildfires around the globe is increasing. At the same time, urban development is expanding outward into areas where severe fires occur. There is an increased risk of home loss to fires in areas where severe fires and urban expansion meet. Ignition of homes or nearby fuel is...

  • 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...

  • Effect of Active Trailing Edge Motion Upon Airfoil Energy Harvester

    Creator:
    Strahl, Jordan D.
    Abstract:
    The application of a flapping foil with prescribed trailing edge motion to energy harvesting in a low reduced frequency (k = fc/U∞) regime was experimentally studied. The effects of the phase and amplitude of the applied trailing edge motion upon time-variant power extraction capability have been measured and are interpreted....

  • The COVID-19 pandemic’s effect on outdoor recreation

    Creator:
    Davis, Jensen
    Abstract:
    In the spring of 2020, the COVID-19 pandemic began. This prompted quarantines, mask mandates, and stopped many businesses and services. This study asked the question of what people decided to do in terms of their recreation habits in response to the pandemic. We took a sample of Oregon State University...
