  • Effect of Active Trailing Edge Motion Upon Airfoil Energy Harvester

    Creator:
    Strahl, Jordan D.
    Abstract:
    The application of a flapping foil with prescribed trailing edge motion to energy harvesting in a low reduced frequency (k = fc/U∞) regime was experimentally studied. The effects of the phase and amplitude of the applied trailing edge motion upon time-variant power extraction capability have been measured and are interpreted....

  • Temperature Evolution of Nonreacting Spark Kernels at Sub-Atmospheric Pressures

    Creator:
    Caplan, Daniel L.
    Abstract:
    In the event of a mid-flight flameout of a gas turbine engine, reignition is paramount to occupant safety. Ignition at high altitude can be challenging, due in part to the potentially lower ambient pressures. An understanding of the effects of sub-atmospheric pressures on the temperature evolution of spark kernels is...

  • A Manufacturing Process Design for Producing a Membrane-based Energy Recovery Ventilator with High Aspect Ratio Support Ribs

    Creator:
    Kawula, Steven P.
    Abstract:
    Heating, ventilation, and air conditioning systems represent nearly half of building energy usage in the United States. Recent building regulations requiring increased air turnover within buildings will result in even greater air conditioning usage. To alleviate these concerns, membrane-based heat-and-moisture exchangers known as energy recovery ventilators have been developed to...

  • Power Cycle Selection and Optimization for a Small Modular Reactor

    Creator:
    Kissick, Sean M.
    Abstract:
    As a way to improve safety and economics, one area of research and commercialization of new nuclear power plants has focused on the development of small modular reactors (SMRs). NuScale Power has developed a 50 MWe natural convection cooling SMR coupled with a regenerative Rankine cycle. Current estimates place the...

  • 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...

  • 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...

  • Computational modeling of a diffusion bonded microchannel under high pressure and temperature

    Creator:
    Pratte, William
    Abstract:
    Diffusion bonded microchannels provide significant benefits by reducing space requirements while improving thermal efficiency when used in heat exchangers. In particular, these microchannels have potential to improve efficiencies for combining concentrated solar power with supercritical CO2 Brayton cycles, where structures operate at high temperatures (760 ˚C) and high pressures (25...

  • Two-Color Laser Induced Fluorescence Imaging of Fluid Temperature for Free Convection and Vapor Condensation

    Creator:
    McAfee, Rachel
    Abstract:
    The development of a continuous and reliable cooling method for computer chips is an evolving subject requiring continuous research in both computer science and thermal management. Two-color laser induced fluorescence (LIF) provides a non-invasive way to investigate electronics cooling fluid behavior. Dielectric fluids are of particular interest as they allow...

  • Manufacturing Process Design for a Stamped Microchannel High-Temperature Recuperator

    Creator:
    Song, Chuankai
    Abstract:
    Microchannel high temperature recuperators have the advantage of higher heat transfer coefficients and lower size and weight than traditional high temperature recuperators. However, the industrial application of microchannel recuperators are restricted by the high cost of photochemical machining and diffusion bonding. The objective of this paper is to introduce a...

  • Fouling Characterization in Hypersaline Wastewater Treatment

    Creator:
    Messer, Morgan S.
    Abstract:
    Water supplies are diminishing worldwide and by 2025 two thirds of the population could be living in regions of water scarcity (local demand for water is greater than water supply). One method to increase available water sources is to use desalination technologies to separate water from saline solutions. While desalination...
