  • Fluidized Bed Reactor Engines

    Creator:
    Lavrich, Zoe A.
    Abstract:
    Repurposing internal combustion engines as petrochemical reactors (i.e., Reactor engines) could offer a smaller, scalable alternative to traditional full scale chemical processing facilities. For many chemical processes, incorporating catalyst particles in fluidized beds is expected to result in superior performance over both monoliths and packed beds. Conversion of ethane into...

  • Design and Optimization of a 1 kW Hybrid Powertrain for Unmanned Aerial Vehicles

    Creator:
    Brown, Sean P.
    Abstract:
    A 1 kW series hybrid powertrain was developed at Oregon State University for use in unmanned aerial vehicles (UAVs). This powertrain was designed to give mission flexibility and increased flight time to fixed-wing vertical takeoff and landing UAVs and multirotor UAVs. The powertrain components, an internal combustion engine and a...

  • A modeling and empirical study of a novel bimodal natural gas internal combustion engine with fuel compression capability

    Creator:
    Elgin, Robert C., III
    Abstract:
    Given the current abundant supply and cheap price of natural gas (NG) in the United States, there is a significant opportunity to use this fuel for transportation. However, there are few fueling stations for consumers. To address this need, a dual-mode engine has been developed where in one mode all...

  • Development and Application of a Reduced Chemical Kinetics Model for Low-Speed Pre-Ignition Investigation

    Creator:
    Tran, Khang NV.
    Abstract:
    Gasoline direct injection engines, with downsized boosted technology, present a promising option for enhancing power density and reducing fuel consumption for next-generation engine designs to meet stringent fuel economy and emission standards. However, these developments in the low-speed and high-load operating regime are challenged by the occurrence of a new...

  • Chemometrics-based Approach for Predicting Low Temperature Combustion Engine Fuel Performance

    Creator:
    Daly, Shane
    Abstract:
    Low temperature combustion (LTC) engines offer improved efficiency and reduced emissions over traditional gasoline spark-ignited and diesel compression-ignition engines. The ability to produce fuels optimized for LTC engines could help increase efficiency and therefore improve fuel economy, insomuch that Federal fuel economy standards could be met. Currently, a fuel performance...

  • Design of a heat exchanger network to challenge controller design methods

    Creator:
    Pashak, Jeffrey J.
    Abstract:
    A simple heat exchanger network has been studied as an example of a dynamically interactive process. The process is relatively simple, requiring only temperature measurements and flow rate manipulations. Equations are presented for the design of a physical process having a specified steady-state Relative Gain Array and specified dynamic characteristics....
