  • Turbulent flow of liquid-liquid dispersions : drop size, friction losses, and velocity distributions

    Creator:
    Ward, John Philip
    Abstract:
    The momentum transfer characteristics of liquid-liquid dispersions were studied under conditions of turbulent flow in a cirular conduit. Experiments were conducted to obtain drop size, friction factors and velocity profiles for three organic phases dispersed in water. The test sections consisted of straight copper tubes 1-inch OD and 0.830-inch ID....

  • Single phase turbulent mixing between adjacent channels in rod bundles

    Creator:
    Galbraith, Kirk Powell
    Abstract:
    The turbulent interchange of matter between parallel adjacent subchannels in a simulated rod bundle for single phase flow was investigated to determine the effects of mass flow rate and rod spacing. The simulated rod bundle was made by placing six 1-inch diameter rods in a square-square array. The overall test...

  • Study of creeping, inertial and turbulent flow regimes in porous media using particle image velocimetry

    Creator:
    Patil, Vishal A.
    Abstract:
    Porous media flows are encountered in many natural and man-made systems such as gas adsorption, filtration, heat exchangers, combustion, catalytic reactors and groundwater hydrology. This study experimentally investigates these flows as function of pore Reynolds number, Re[subscript pore]. The pore Reynolds number is based on the porous bed hydraulic diameter,...

  • Evolution of Turbulence, Heat Content, and Freshwater Lenses in the Diurnal Warm Layer

    Creator:
    Moulin, Aurélie J.
    Abstract:
    Thorough understanding of the mechanisms controlling the temperature structure in the surface mixed layer of the ocean and, in particular, accurate values of sea surface temperature are critical for properly parameterizing air-sea heat exchange and quantifying the amount of heat redistributed below the surface. It is however difficult to obtain...

  • DNS study of Particle-bed-Turbulence Interactions in Oscillatory Flows

    Creator:
    Ghodke, Chaitanya Deepak
    Abstract:
    Turbulent flows over rough surfaces are encountered in many engineering and geophysical applications. Flows of this nature, due to their increasing technological interests, have been a subject of rigorous investigation in recent years. Of the particular interest to the oceanographic community is the study of turbulent oscillatory flow over rough...

  • Turbulence and biophysical fluxes in the near surface ocean

    Creator:
    Hoecker-Martínez, Martín
    Abstract:
    Vertical transports of plankton, momentum, heat, and turbulence are modeled. A novel integration of high resolution turbulence and biophysical modeling is used to show the influence of a Kelvin-Helmholtz instability on the vertical migration of simple gyrotactic organisms. A viscous limit on mixing driven by shear turbulence is proposed. Large...

  • Turbulence in sheared, salt-fingering favorable environment

    Creator:
    Kimura, Satoshi
    Abstract:
    Instability and turbulence in sheared, salt-fingering favorable stratification are studied using three-dimensional direct numerical simulations (DNS). Salt-fingering favorable stratification is gravitationally stable, because the unstable vertical gradient of salinity is stabilized by temperature (warm, salty over cool, fresh water-masses). Salt-fingering instability can occur at the interface of these different water-masses....

  • An experimental/analytical investigation of buoyant jets in shallow water

    Creator:
    Hsiao, Entsung
    Abstract:
    This thesis presents the results of an experimental and analytical study of single-port buoyant turbulent jets discharged into shallow water. The experimental results include the measured downstream dilution, centerline concentration and trajectory. Independent parameters considered were Froude number, submerged depth, discharge angle and velocity ratio. Results indicate that decreasing the...

  • An investigation of upwelling along the Oregon coast

    Creator:
    Smith, Robert Lloyd
    Abstract:
    The oceanic phenomenon of upwelling along the Oregon coast is examined. Upwelling in both the open ocean and coastal regions is discussed. An idealized model is used, envisaging the ocean off Oregon to consist of homogeneous surface and deep layers separated by a pycnocline. The equations of motion are solved...
