  • Heat transfer in magnetic fluids at low Reynolds number

    Creator:
    Choi, Sang Hyouk
    Abstract:
    This study was concerned with the flow of a magnetic self-propelled ferrohydrodynamic fluid in a horizontal circular tube subjected to axially varying temperature and magnetic field. The first phase of the study involved the analytical solution to the governing equations for the velocity and temperature profiles within the fully developed...

  • Large displacement, high Reynolds number oscillating cylinder

    Creator:
    Chan, Yau Wai
    Abstract:
    Hydrodynamic forces on a cylinder oscillating horizontally underwater with its axis perpendicular to the motion were measured at the Oregon State University Wave Research Facility. The cylinder had an outer diameter of 12 inches and a length of 12 feet. For the data presented herein, the maximum displacement of the...

  • Structural factors affecting wear of cobalt base hard facing alloys

    Creator:
    Gifford, Raymond Warren
    Abstract:
    This paper is a metallurgical study of the microstructure of a cobalt base hard facing alloy to determine the cause for inconsistant wear properties. Wear tests on a Stellite 6 alloy, deposited using oxyacetylene welding techniques, resulted in a wide range of weight losses. Microscopic examination has revealed the probable...

  • Experimental and analytical characterization of bidirectional reflectance data for engineering materials

    Creator:
    Zaworski, Joseph Robert
    Abstract:
    Bidirectional reflectance is a fundamental property used for the analysis of radiative heat transfer. It is a form of reflectivity in which the spectral and directional dependencies of both the beam incident on a surface and the beam reflected from the surface are specified. A new system has been designed...

  • Experiments on a low aspect ratio wing at low Reynolds numbers

    Creator:
    Morse, Daniel R.
    Abstract:
    At the start of the 21st century much of the focus of aircraft design has been turned to unmanned aerial vehicles (UAVs) which generally operate at much lower speeds in higher risk areas than manned aircraft. One subset of UAVs are Micro Air Vehicles (MAVs) which usually are no larger...

  • A numerical study of inertial flow features in moderate Reynolds number flow through packed beds of spheres

    Creator:
    Finn, Justin Richard
    Abstract:
    In this work, flow through synthetic arrangements of contacting spheres is studied as a model problem for porous media and packed bed type flows. Direct numerical simulations are performed for moderate pore Reynolds numbers in the range, 10 ≤ Re ≤ 600, where non-linear porescale flow features are known to...

  • Implementing a Multi-Agent Approach to a Graph-Based Topology Optimization

    Creator:
    Bai, Gaofeng
    Abstract:
    In order to solve some classic problems in traditional topology optimization, such as unknown material distribution, checker-boarding and curse of dimensionality, this thesis introduces a new method to construct a mechanical structure that can reduce mass and increase stiffness. It uses a graph to represent the skeleton of a structure....

  • Rational Fuel Design for Low Temperature Internal Combustion Engines

    Creator:
    Daly, Shane R.
    Abstract:
    This work introduces a new methodology to design transportation fuels offering improved efficiency and reduced emissions, aimed to complement both traditional and emerging engine technologies. Many of these emerging technologies are centered around exploiting low temperature combustion (LTC) strategies that offer improved efficiency and reduced emissions. However, a standardized fuel...

  • An experimental investigation of drilling mud discharged into a flowing stratified environment

    Creator:
    Mohebbi, Behrooz
    Abstract:
    An experimental study of the short-term fate of a drilling mud discharged into a flowing stratified environment was conducted to determine its dilution and settling characteristics. The drilling mud used in this test had a specific gravity of 1.184 and a composition of 12 percent by weight high-gravity solids (BaSO₄)...

    Abstract:
    The “why” of any situation is one of the most important questions to ask. Inventors have ideas every day. Some ideas are the brilliant ideas that lead to a better tomorrow. To protect these ideas, inventors turn to patents, a governmental grant of the right to stop others, for a...
