  • Analysis of the Effects of Combustion Products on Forced Ignition and Turbulent Flame Propagation

    Creator:
    Bonebrake, Jonathan M.
    Abstract:
    Practical combustion devices frequently rely upon forced ignition of turbulent fuel/oxidizer mixtures that also contain the product species of combustion. Examples of this include engines that use exhaust gas recirculation (EGR), inter-turbine burners in aircraft engines, and other systems the utilize staged combustion. In this work, the effects of major...

  • Equipment replacement prioritization measures : simulation and testing for a vehicle fleet

    Creator:
    Kriett, Phillip Oliver
    Abstract:
    Oregon Department of Transportation (ODOT) Fleet Services manages a fleet that in 2008 included approximately 5,000 pieces of active equipment worth $340–$390 million. Every biennium, a fixed budget is available to replace a certain amount of this equipment. This research evaluated various measures for establishing equipment replacement priorities. A model...

  • Reduced order multi-legged mathematical model of cockroach locomotion on inclines

    Creator:
    Peterson, Delvin E.
    Abstract:
    While the locomotion performance of legged robots over flat terrain or known obstacles has improved over the past few decades, they have yet to equal the performance of their animal counterparts over variable terrain. This work analyzes a multi-legged reduced order model of cockroach locomotion on variable slopes which will...

  • A comparison of single runs versus multistart for simulated annealing and threshold accepting

    Creator:
    Crews, Matthew
    Abstract:
    Simulated Annealing and Threshold Accepting are two stochastic search algorithms that have been successfully used on a variety of complex and difficult problem sets. Due to their stochastic nature they are not guaranteed to produce the same result for each run. This means that these techniques actually produce a distribution...

  • Incidental Sensor Networks for Human Mobility Detection

    Creator:
    Hoover, Sylvan
    Abstract:
    Transportation systems need to get better by moving ever more people while consuming ever fewer resources. To build better transportation systems, planners need an accurate understanding of how people exercise mobility and tools to apply that understanding to the transportation system. Such an understanding can come through the development of...

  • A Text-based Simulation Framework for the Automated Simulation and Analysis of Manufacturing Assembly Systems

    Creator:
    Fields, Benjamin G.
    Abstract:
    The rapid advancement of manufacturing has led to the creation of a myriad of technologies that facilitate the analysis and simulation of manufacturing processes. These technologies have become a pivotal component in maintaining and improving processes in today’s complex manufacturing environments. Discrete Event Simulation (DES) is one such technology that...

  • 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...

  • Temperature Evolution of Spark Kernels in Quiescent and Cross-flow Conditions

    Creator:
    Okhovat, Sebastian
    Abstract:
    Numerous physical and chemical processes are required for successful ignition of a flammable mixture, many of which have been well characterized. However, one aspect of the ignition process that has received limited consideration is understanding the temperature of the spark kernel. A spark kernel is the volume of heated gas...

  • Performance characterization of an integrated microscale hydrogen combustor recuperator and oil heat exchanger

    Creator:
    Haley, David B. (David Brien)
    Abstract:
    Experiments on a novel, microscale hydrogen combustor heat exchanger (µCHX) are presented in this thesis. The µCHX has been designed to efficiently transfer thermal energy to a heat transfer fluid for use in desorption of hydrogen from a metal hydride storage system of a hydrogen-powered fuel cell vehicle. The experimental...
