  • Experimental Design Approach for Evaluation of Airfoil-Driven Energy Harvesting

    Creator:
    Strahl, Jordan D.
    Abstract:
    An experimental setup has been partially developed to investigate the impact of an actively controlled trailing edge component upon the energy harvesting performance of an oscillating airfoil in a pitching and heaving regime. While previous and current efforts have and continue to function to characterize the performance of such a...

  • Radiation Emissions from Turbulent Diffusion Flames Burning Large Hydrocarbon Fuels

    Creator:
    Zeuthen, Eric D.
    Abstract:
    The purpose of this study is to measure and compare radiation emissions from flames burning large hydrocarbon fuels to assist in understanding how the molecular composition changes radiation emissions. Radiative heat transfer is significant because it is a primary mode of heat transfer for many combustion devices. This study also...

  • Radiation from an infinite plane to parallel rows of infinitely long tubes - hottel extended

    Creator:
    Qualey, Douglas L.
    Abstract:
    A two-dimensional model for predicting the rate of radiation heat transfer for the interior of an industrial furnace is described. The model is two-dimensional due to the assumptions of the heat source as an infinite radiating plane and the heat sink as rows of parallel tubes that are both infinite...

  • An analytical model for fatigue crack propagation

    Creator:
    Anderson, James L.
    Abstract:
    Beginning with the basic equations from the theory of elasticity and employing a model of crack propagation based on the concept of a constant plastic energy absorption per unti of crack extension, the commonly accepted power law of fatigue crack propagation was derived. This derivation uses an extension of the...

  • 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...

  • 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...

  • 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...

  • Combustion Characteristics of a Jet Fuel and its Surrogate in MILD Conditions

    Creator:
    Weide, Parker D.
    Abstract:
    This research seeks to identify how changes in temperature and oxygen concentration in the reaction zone affects liftoff heights for moderate or intense low-oxygen dilution (MILD) combustion of a jet fuel and a surrogate fuel. MILD combustion offers a method of burning fuels with reduced CO and NOx production by...

  • Investigation of Destratification in Warehouses

    Creator:
    Polander, Michael D.
    Abstract:
    A significant source of energy consumption comes from maintaining desired indoor environment conditions in warehouses and other industrial facilities. In efforts to combat the raising energy costs, studies into more efficient heating and cooling strategies has been a topic of consideration for a number of years. One of the areas...
