  • The experimental characterization of membrane behavior in two-phase gas extraction

    Creator:
    Cappello, Nicholas C.
    Abstract:
    Understanding the behavior of hydrophobic membranes is important for applications where separating a gas from a liquid-gas mixture is beneficial. For example, in-situ vapor extraction can be used in microscale heat sinks to improve heat transfer and flow stability. In this study, gas is experimentally evaluated flowing through flexible polytetrafluoroethylene...

  • Predicting rebound of planar elastic collisions

    Creator:
    Cruz-Conde Gret, Raphaël
    Abstract:
    Impact is a large and complex field. It embraces both structures as simple as a nail, and more complex systems, such as a car collision. A central feature of impact theory is finding the dependence between the velocities before and after impact. The transformation law of the velocities in an...

  • Rebound predictions of mechanical collisions

    Creator:
    Lai, Liang-Ju
    Abstract:
    Predictions of mechanical collisions between two bodies frequently cannot be completed by the impulse-momentum equation together with a complete description of the motion of the system at the initial contact. Additional account must be taken of the deformations and frictional interaction induced by the impulsive reaction force, where the bodies...

  • Energy resource conservation in new large power plants

    Creator:
    King, David C.
    Abstract:
    This thesis evaluates new, large power generating plants of the various types expected to be practicable in the time span of the next 50 years. By using thermodynamic principles, the plants are evaluated on the basis of conservation of energy; the basic assumption is that the best policy is the...

  • Nonlinear adaptive control of highly maneuverable high performance aircraft

    Creator:
    Cho, Sul
    Abstract:
    This thesis presents an effective control design methodology using a one-step-ahead prediction adaptive control law and an adaptive control law based on a Lyapunov function. These control law were applied to a highly maneuverable high performance aircraft, in particular, a modified F/A-18. An adaptive controller is developed to maneuver an...

  • Discrete-time explicit model reference adaptive control for robotic manipulators

    Creator:
    Yuh, Junku
    Abstract:
    In this dissertation a direct approach to discrete-time model reference adaptive control (MRAC) based on hyperstability theory is proposed to control industrial robotic manipulators. For industrial robots and manipulators, which usually have highly nonlinear and complex dynamic equations and often have unknown inertia characteristics, it is very difficult to achieve...

  • Laminate mixing in microscale fractal-like merging channel networks

    Creator:
    Enfield, Kent E.
    Abstract:
    A two-dimensional model was developed to predict concentration profiles from passive, laminar mixing of concentration layers formed in a fractal-like merging channel network. Both flat and parabolic velocity profiles were used in the model. A physical experiment was used to confirm the results of the model. Concentration profiles were acquired...

  • An Improved Chemical Kinetic Model Reduction in pyMARS for Liquid Propellants

    Creator:
    Moore, Cailin J.
    Abstract:
    The aerospace industry uses chemical kinetic models when designing propulsion systems to acquire specific details about the rate of chemical reactions, heat release, and combustion stability. These models, however, are too large and stiff to be useful as they can take weeks to run computations on. The pyMARS python package...

  • 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...
