  • Turbulent Combustion Analysis of Large Hydrocarbon Fuels in a Reduced Pressure Environment

    Creator:
    Schorn, Nathan E.
    Abstract:
    The aviation industry is pushing for better fuels and gas turbine engines for several reasons: cost, emissions, and to a lesser extent high-altitude relights. One aspect that research has been focused on to help reduce costs, emissions and better understand high-altitude relights is studying the combustion behavior of the fuel...

  • 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...

  • 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....

  • 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...
