  • The Mira 2 Rocket Engine: Applying Lessons Learned for an Improved Iteration

    Creator:
    Dimas-Harms, Colton R.
    Abstract:
    In this paper, I present the design of Mira 2, a small-scale, liquid bipropellant rocket engine, with a specific focus on its oxidizer-centered pintle injector. Building upon the valuable lessons and insights gained from the empirical testing of its predecessor, Mira 1, the Mira 2 engine incorporates several improvements and...

  • Interactions of a fully modulated inclined jet with a crossflow

    Creator:
    Dano, Bertrand P. E.
    Abstract:
    Jets in crossflow are used in a wide range of engineering applications and have been studied for more than 60 years. The transversal penetration and structure of a jet placed in a crossflow is known to be strongly three-dimensional. It is believed that, by using a pulsed jet inclined in...

  • An approach to reduced-order modeling and feedback control for wave energy converters

    Creator:
    Shoori J., Hesam E.
    Abstract:
    Wave energy holds great promise to be part of the alternative energy portfolio that will provide independence from fossil fuels. As wave energy converter (WEC) technologies mature, designing effective control strategies to extract maximum energy, extend device life, coordinate WEC operation within an array, or mitigate negative impacts of a...

  • Flow characteristics of semi-confined impinging jet arrays

    Creator:
    Dano, Bertrand P. E.
    Abstract:
    The present study proposes to investigate the flow structure of different arrays of jets impinging on a flat surface enclosed by three walls, creating a channel that forces the air to leave in one preferential direction, generating a self sustain crossflow. Details of both the mean and some turbulence quantities...

  • Predicting Properties of Bio-jet Fuels using Machine Learning and ATR-FTIR Spectroscopy

    Creator:
    Mayer, Morgan A.
    Abstract:
    High-potential molecules derived from biomass sources may suitably replace or supplement traditional nonrenewable hydrocarbon fuels to reduce pollution and fuel processing costs. Due to expensive and time-consuming property testing, models that predict key properties from optical data would initially vet potential additives before investment and bench-scale testing. Attenuated Total Reflection...

  • Computational modeling of Lorentz force induced mixing in alkali seeded diffusion flames

    Creator:
    Thompson, Jon Ira
    Abstract:
    Lorentz forces provide a unique method for the control and mixing of gas flows without the physical intrusion of objects into the flow. Lorentz forces arise when an electric current is passed through a volume in the presence of a magnetic field. The interaction between the electric current and the...

  • Computational Modeling of Smoldering Combustion in Wildland Fuels

    Creator:
    Jayasuriya, Waduge Jayani A.
    Abstract:
    Smoldering combustion in wildland fires is a critical phenomenon that needs in-depth study because it can initiate with weaker ignition sources, can persist for long periods, is difficult to suppress, and can transit to flaming combustion. Cellulose, hemicellulose, and lignin are the major organic constituents within biomass, in varying proportions...

  • A numerical study of solid fuel combustion in a moving bed

    Creator:
    Ko, Daekwun
    Abstract:
    Coal continues to be burned by direct combustion in packed or moving bed in small size domestic furnaces, medium size industrial furnaces, as well as small power stations. Recent stringent restrictions on exhaust emissions call for a better understanding of the process of combustion of coal in beds. The present...

  • A study of laser generated Rayleigh and Lamb waves in graphite/epoxy composites

    Creator:
    Park, Heeyong
    Abstract:
    The application of laser generated ultrasonics was first demonstrated in the mid-seventies and has shown good potential when applied to isotropic materials. However, its use with composite materials is still in the early stages of development. This study explores the potential for application of laser generated Rayleigh and Lamb waves...
