  • 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...

  • An analytical model for predicting truck performance on interstate highways

    Creator:
    Cantwell, William Curtis
    Abstract:
    This thesis describes a Truck Performance Simulation Model developed for use in a United States Department of Transportation university research project entitled "The Energy, Economic and Environmental Consequences of Increased Vehicle Size and Weight." The performance of the truck is found by specifying its engine, driveline and tire characteristics and...

  • Fluid forces on and flow configurations around a circular cylinder near a plane boundary

    Creator:
    Tavolacci, Don
    Abstract:
    The flow configurations around and the forces acting on a circular cylinder with its axis parallel to a nearby plane boundary and subjected to a uniform flow were investigated. The flow conditions, which were perpendicular to the cylinder axis and parallel to the plane boundary were investigated experimentally and theoretically....

  • Combustion gas emissions spectra of Otto cycle engine operating on H₂, CO, and gasoline using a calibrated vidicon detector spectrometer

    Creator:
    Freeburn, Scott Alan
    Abstract:
    The capabilities of the Tektronix Model J2C/7J20 Rapid Scanning Spectrometer for the determination of molecular species resulting from Otto cycle combustion were experimentally investigated after a literature search of the subject area. Combustion of hydrogen-air, carbon monoxideair, and gasoline-air mixtures in the combustion chamber of a Cooperative Fuel Research engine...

  • Vibrations of suspended cables

    Creator:
    Gale, John Gregg
    Abstract:
    The equations of motion of an elastic cable suspended in a viscous medium from two arbitrary points are derived. These are then linearized for the undamped, inextensible case, and it is found that the equations describing the in-plane motion of the cable are then independent of the equation describing the...

  • A portable pumping system for hydraulic excavation of commercial crab pots

    Creator:
    Chang, Terrill John
    Abstract:
    The design and testing of a portable pumping system for use in the hydraulic excavation of commercial crab pots buried by ocean sediment was undertaken. The resulting portable system retained the four major components of the pumping systems presently used by commercial fishermen: engine, pump, fire hose, and nozzle. Because...

  • Polycarbonate as a photoplastic stress freezing material

    Creator:
    Broderick, John Justin
    Abstract:
    Dead weight creep tests were conducted on polycarbonate in order to determine if it is a linear viscoelastic material; or if it is not, then to determine the feasibility of photoplastic stress freezing. Secondary objectives were: the determination of the parameters in the creep compliance of a four element viscoelastic...

  • A numerical analysis of ice fog produced by automobiles

    Creator:
    Nelson, William George
    Abstract:
    A model of an exhaust plume was developed and programmed on a digital computer. The purpose of the model was to predict the concentration and size distribution of ice particles produced from automobile exhaust during arctic conditions. The model accounted for the nucleation, growth, and freezing of the condensed water...

  • Combustion mechanisms in wood fired boilers

    Creator:
    Tuttle, Kenneth Lewis
    Abstract:
    A program of research has been established at Oregon State University to study wood residue combustion using an experimental spreader-stoker combustor. This research was conducted to increase the understanding of combustion occurring in wood fired boilers. Using Douglas Fir screened to 3/8-3/4 inches, two 4x4 factorial experiments were conducted varying...
