  • A numerical study of the response of Lake Kinneret to wind forcing

    Creator:
    Vernieres, Guillaume
    Abstract:
    Lake Kinneret is Israel's only fresh water lake (unless you count the Dead Sea). It spans roughly 20km from north to south, and about 12km at its widest east west extent. It is not quite 50m deep at its deepest point. In late spring, the lake stratifies significantly and remains...

  • A modeling study of katabatic flows

    Creator:
    Smith, Craig M.
    Abstract:
    A modeling study is undertaken to better understand the physics of katabatic flows. This study is divided into three topics; a comparison between a large eddy simulation (LES) and a mesoscale model of katabatic flows, a sensitivity study of katabatic flows to various physical parameters, and an investigation into the...

  • Discrete-time blade pitch control for wind turbine torque regulation with digitally simulated random turbulence excitation

    Creator:
    Sharif-Razi, Ali-Reza
    Abstract:
    A time domain simulation model which approximates the three-dimensional velocity fluctuations of wind turbulence has been developed. This model is used in a discrete time control algorithm to regulate the output torque of a wind turbine by changing the pitch angle of the turbine blade. The wind model provides a...

  • Dynamics of the nearshore wave bottom boundary layer

    Creator:
    Foster, Diane Lyn
    Abstract:
    This thesis presents an examination of the nearshore wave bottom boundary layer under conditions of significant sediment response. Using both field observations and simple models, the response of the bottom boundary layer to random waves is shown to have a complex behavior. First, the linearized wave bottom boundary layer governing...

  • Shear waves in a circular wave basin

    Creator:
    Berkery, Lynn A.
    Abstract:
    Shear waves, which are instabilities of the longshore current, are of interest to nearshore research because they can act as a cross-shore mixing mechanism for the current. The best method to study them is in a controlled environment, such as circular wave tank where continuous longshore currents can be generated....

  • Numerical computation of free surface water flow

    Creator:
    Kuhnert, Jorg
    Abstract:
    The present thesis is a report of investigations on a model for computing the water flow in the wave tank of the OSU Wave Laboratory. A wave board, established at one end of the 100 m long, 4 m wide and 6 m deep wave tank, produces water waves by...

  • Field validation of a nearshore circulation model for alongshore-nonuniform flows

    Creator:
    Wilson, Gregory W.
    Abstract:
    We investigate, theoretically and experimentally, the problem of modeling depth-integrated (2DH) surf zone circulation on an alongshore-nonuniform natural beach, with waves approaching from an arbitrary angle. An approximate theoretical model is developed, which captures the important effect of advection in the alongshore dynamics, and shows that a nondimensional parameter Re[subscript]s...

  • Modeling shallow-water hydrodynamics : rotations, rips, and rivers

    Creator:
    Long, Joseph W.
    Abstract:
    Hydrodynamic models are used as a diagnostic tool to understand the temporal variability of shallow-water processes that are difficult to completely resolve with traditional field measurements. For all simulations, modeled quantities are qualitatively or quantitatively compared with available measurements to gain confidence in conclusions derived from the modeled results. In...

  • Fractal solutions to the long wave equations

    Creator:
    Ajiwibowo, Harman
    Abstract:
    The fractal dimension of measured ocean wave profiles is found to be in the range of 1.5-1.8. This non-integer dimension indicates the fractal nature of the waves. Standard formulations to analyze waves are based on a differential approach. Since fractals are non-differentiable, this formulation fails for waves with fractal characteristics....
