  • Shocks and Awe : Damping Selection in Racecars to Maximize Grip

    Creator:
    Takaro, Trevor M. F.
    Abstract:
    This thesis covers the use of a quarter car model to select damping rates for aFormula Student (FS) car, focusing on minimizing vertical tire force variation to improvegrip. A 2 degree of freedom (DOF) quarter car model is cycled over the road frequenciesof interest and the results compared with the...

  • A force plate for measuring contact forces during dependent transfers onboard aircraft

    Creator:
    Schafer, Christopher A.
    Abstract:
    The transfer of air travelers with disabilities between a mobility aid and an aircraft seat is a major source of injury for both the travelers and the airline personnel assisting in the transfer. The risk to both parties might be reduced through the biomechanical study of the transfer task. Such...

  • A Permanent-Magnet Linear Generator Wave Energy Converter for Low Power Ocean Sensors

    Creator:
    Miles, Lillian F.
    Abstract:
    Renewable energy sources are becoming increasingly important due to their low environmental impact and limitless nature. This thesis explores the design of a 250 mW permanent magnet linear generator wave energy converter to power ocean sensors. While many wave energy converters exist, this is a unique application because the wave...

  • An experimental investigation of transition pool boiling

    Creator:
    Aoki, Tadao
    Abstract:
    The heat-transfer phenomena studied in this work were associated with pool boiling from a flat horizontal surface facing upward with the bulk liquid at its saturation temperature. The analysis of boiling sound and the investigation of the transition boiling mechanism constituted the essence of the present study. The distinctively large...

  • Simulaton of a solar heating and cooling system with experimental evaluation

    Creator:
    Layton, William Clifford
    Abstract:
    This thesis is concerned with simulating two forms of energy retrieval. Standard computer programs are routinely used to simulate such energy systems. However, the accuracy of these simulations is not well documented. The main objective of the work presented here is to evaluate the validity of this type of simulation...

  • Experimental study of two-phase gas-liquid flow in a microscale fractal-like branching flow network

    Creator:
    Kwak, Younghoon
    Abstract:
    Two-phase gas-liquid flows in microscale fractal-like branching channel flow networks were experimentally studied to assess the validity of existing void fraction correlations and flow regimes based on superficial gas and liquid velocities. Void fractions were assessed using two different methods. First, void fraction data were acquired using a High-Speed-High-Resolution (HSHR)...

  • Modified linear theory and Kalman filtering for in flight projectile impact point prediction

    Creator:
    Hainz, Leonard C.
    Abstract:
    A method for real time in-flight prediction of the ground impact point of an indirect fire projectile is investigated. The method investigated is comprised of a combination of an impact point predictor and an extended Kalman filter state estimator based on modified linear theory. The modified linear theory model is...

  • Integrated forward light scattering as a measure of aerosol mass concentration

    Creator:
    Tomine, Chris Shinya
    Abstract:
    A mathematical model was developed that relates the ratio, R, of two light flux measurements to the mass concentration, m, of the atmospheric aerosol particles between a source of parallel light (e.g., the sun) and the measuring system. R is defined as the ratio of the light fluxes passing through...

  • A computer imaging method for fluid motion studies in metal casting

    Creator:
    Poland, John H.
    Abstract:
    Significant reductions in the number of defects in parts produced by investment casting can be obtained by improving the flow of the molten metal during pouring. Studies have been done at Oregon State University with simulated casting techniques to determine optimal mold configurations. Better mold layouts have been shown to...

  • Design considerations for a miniature atmospheric engine with a magnet-actuated autonomously-reciprocating in-cylinder regenerator for portable power production

    Creator:
    Yarger, David J.
    Abstract:
    Driven by the need for high energy-density power sources, demand has stimulated the development of small-scale engines. A small-scale engine with a fuel supply could replace batteries and utilize higher energy-density liquid hydrocarbon fuels; such an advance could deliver a new age of portable devices. Currently, operable small-scale engines exist;...
