  • Experimental Investigations of the Unsteady Aerodynamics of Oscillating Airfoils Operating in the Energy Harvesting Regime

    Creator:
    Siala, Firas F.
    Abstract:
    The rising global trend to reduce dependence on fossil fuels has provided significant motivation toward the development of alternative energy conversion methods and new technologies to improve their efficiency. Recently, oscillating energy harvesters have shown promise as highly efficient and scalable turbines, which can be implemented in areas where traditional...

  • 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...

  • Experiments on a low aspect ratio wing at low Reynolds numbers

    Creator:
    Morse, Daniel R.
    Abstract:
    At the start of the 21st century much of the focus of aircraft design has been turned to unmanned aerial vehicles (UAVs) which generally operate at much lower speeds in higher risk areas than manned aircraft. One subset of UAVs are Micro Air Vehicles (MAVs) which usually are no larger...

  • 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...

  • Study of Energy Harvesting Performance of Oscillating Airfoils using a Discrete Vortex Model

    Creator:
    Kamrani Fard, Kiana
    Abstract:
    The energy harvesting performance of oscillating airfoils is studied using a discrete vortex model (DVM) with a leading-edge separation criterion. The airfoil undergoes a combined sinusoidal heaving and pitching motion at reduced frequencies of k = 0.06 − 0.16, with heaving amplitude of h0 = 0.5c, and pitching amplitude of...

  • Applications of the thermal wave technique in liquid thermal conductivity measurements and flow field diagnostics

    Creator:
    Wang, Zhefu
    Abstract:
    The thermal wave technique has been explored for the use of liquid thermal conductivity measurement and flow property diagnostics in this dissertation. For liquid thermal conductivity measurements, an experimental technique based on the thermal wave approach is developed. A stainless steel strip functions as both a heating element and a...
