  • Numerical and Experimental Investigation of Wing Flutter Suppression via Distributed Propulsion

    Creator:
    Anderson, Cole J.
    Abstract:
    In a seminal paper published in 1982, scientist have warned that humanity was pushing earth’s ecosystems beyond their capacities to support the web of life. One response to the concern was outlined by NASA with its vision for advanced fixed wing transport aircraft to be environmentally compatible and have revolutionary...

  • Stability and Liftoff of Non-premixed Large Hydrocarbon Flames in MILD Conditions

    Creator:
    Walters, Eric M.
    Abstract:
    The Moderate or Intense Low-oxygen Dilution (MILD) combustion regime has received interest from the industrial furnace and gas turbine engine industries due to attractive properties of reduced NO[subscript x] emissions and high thermal efficiency. MILD combustion is characterized by low oxygen concentrations (i.e. 3%-9% by volume) and high reactant temperatures....

  • Modeling convective boiling flow with in-situ local vapor extraction

    Creator:
    Salakij, Saran
    Abstract:
    The pressure drop of convective boiling flow may be reduced by extracting vapor locally since the entire generated vapor does not have to travel through the entire channel length. In this study, the theoretical model was developed to simulate a convective boiling flow through a fractal-like branching microchannel network with...

  • Crystallization Rates of AIST and Ge Thin Films by Optical and Electron Microscopy

    Creator:
    Bird, Victoriea L.
    Abstract:
    The amorphous to crystalline phase change is of great interest for the production and operation of phase change memory and germanium electronic devices. Phase change memory relies on the ability to differentiate between differences in optical or electrical properties between the amorphous and crystalline phases of a single material. Amorphous...

  • Ground Gen Airborne Wind Energy Conversion Systems: Tools for Conceptual Design and Rapid Prototyping

    Creator:
    Muschler, Alexander
    Abstract:
    Airborne Wind Energy System (AWES) are quickly coming to fruition, with increased energy production while reducing the cost of implementation and materials. This thesis develops a new computational model for a tethered AWES and characterizes a new rapid prototyping method with the objective of supporting the design and rapid prototyping...

  • Energy Harvesting Performance of a Flapping Foil with Leading Edge Motion

    Creator:
    Prier, Michael W.
    Abstract:
    Force data for a flapping foil energy harvester with active leading edge motion operating in the low reduced frequency range is collected to determine how leading edge motion affects energy harvesting performance. The foil pivots about the midchord and operates in the low reduced frequency range of 0.06, 0.08, and...

  • Automated Synthesis of Hybrid Energy Network Optimization using A* & Ensemble Forecasting

    Creator:
    Luc, Jonathan H.
    Abstract:
    This thesis describes a method for automatically generating and evaluating small-scale off-grid energy systems. Such systems are comprised of components such as solar panels, residential-scale wind turbines, batteries, inverters and charge controllers. These disparate components are assembled into feasible networks through the use of topological optimization and graph grammar rules....

  • Determination of cutting forces with asymmetric wedged blades

    Creator:
    Phan, Andrew Vinh
    Abstract:
    Cutting operations using blades appear in several different industries such as food processing, surgical operations, gardening equipment, and so forth. As our society continues to increase our technological prowess, there is an ongoing need to better understand the underlying causes of simple tasks such as cutting so that cutting operations...

  • The fracture toughness of medium density fiberboard and other fiber bridging composites

    Creator:
    Matsumoto, Noah T.
    Abstract:
    In many composites, fiber bridging develops as part of the fracture process. Fiber bridging invalidates many toughness evaluation methods such as the ASTM E399 and complicates the identification of crack length, which is a necessary parameter in energy methods. In order to measure the toughness of fiber bridging composites, an...

  • Modeling, control, and estimation of flexible, aerodynamic structures

    Creator:
    Ray, Cody W.
    Abstract:
    Engineers have long been inspired by nature's flyers. Such animals navigate complex environments gracefully and efficiently by using a variety of evolutionary adaptations for high-performance flight. Biologists have discovered a variety of sensory adaptations that provide flow state feedback and allow flying animals to feel their way through flight. A...
