  • 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 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...

  • Tracking of Melt Pool Motion Using Numerical Analysis of Laser Powder Bed Fusion

    Creator:
    Cox, Bryce
    Abstract:
    Laser Powder Bed Fusion (LPBF) is a process commonly used to create additively manufactured metal parts. The flexibility and complexity allowed by the LPBF process provides opportunity for significant advancement in multiple industries as parts can be customized in shape and function for specific needs. These benefits can be compounded...

  • 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...

  • 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...

  • 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...

  • Experimental Study of the Impact of Physical and Chemical Properties on Smoldering Combustion in Natural Fuels

    Creator:
    Smucker, Benjamin
    Abstract:
    Smoldering combustion in wildland fires is difficult to extinguish, can transition to flaming combustion, and produces a significant amount of pollutants. It is necessary to understand parameters controlling smoldering in order to help predict the smoldering behavior and potentially mitigate these hazards. The wide variety of natural fuels that occur...
