  • 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...

  • 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...

  • Single- and multi-functional arrayed microchannel fluidic devices

    Creator:
    Fisher, Luke W.
    Abstract:
    Novel fluidic devices that utilize an array of microchannels to achieve their designed purpose are discussed. Examples of devices include: fuel reforming using Microreactors, chip cooling using microchannel heat sinks, and microchannel devices used for biological applications. The devices that have directly contributed to this research include: a microchannel water...

  • Sampling submicrometer particles suspended in near sonic and supersonic free jets of air

    Creator:
    Martone, Joseph Arthur
    Abstract:
    This experiment is concerned with sampling submicrometer particles in near sonic and supersonic flows. The study employed a high volume condensation aerosol generator to produce stearic acid particles having a geometric mean diameter of 0.8 μm and a geometric standard deviation of 1.28. The aerosol was diluted with dry air...

  • An investigation of the removal of ozone by activated charcoal

    Creator:
    Liffick, Glenn Lonngren
    Abstract:
    The removal of ozone from an air stream by activated-cocoanut charcoal was investigated from the literature and experimentally. The experimental investigation showed that activated-cocoanut charcoal can be used to remove concentrations of ozone less than 1.0 ppm with high efficiencies. The mechanism of the ozone removal appeared to be a...

  • A model of ciliary streaming in the respiratory system

    Creator:
    Chambers, Alan B.
    Abstract:
    The respiratory tract is lined with a mucous blanket which is motivated by a ciliated epithelium. This blanket includes a lower serous layer of fluid through which the cilia beat and an upper viscid layer into which particulates from the inhaled air are deposited. The movement of the mucous blanket...

    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...

  • Design and performance of a small scale waste heat recovery unit

    Creator:
    Ward, Christopher
    Abstract:
    A microchannel heat exchanger was designed for diesel waste heat recovery and its performance was evaluated. The 21x15x8 cm unit was constructed from diffusion brazed stainless steel lamina and weighed 11 kg. Operating from a 13.4 kW generator with an exhaust temperature of 500 °C the unit delivered 11.1 kW...
