  • Simulation of random, nonlinear wave forces on a circular cylindrical pile

    Creator:
    Tuah, Hang
    Abstract:
    Two types of linear random wave simulation methods are investigated; viz., (1) Deterministic Spectral Amplitude (DSA) and (2) Nondeterministic Spectral Amplitude (NSA). These linear simulations are extended to second-order in a perturbation expansion in the frequency domain by utilizing a Fast Fourier Transform (FFT). The nonlinear interaction matrix for waves...

  • Forces on a transverse circular cylinder in a steady uniform flow near a plane boundary

    Creator:
    Hafen, Blaine
    Abstract:
    An experimental study was conducted to determine the hydrodynamic forces on smooth and roughened circular cylinders as influenced by a nearby plane boundary. The ambient flow was perpendicular to the cylinder and parallel to the boundary. Measurements were taken in a water channel and a wind tunnel to obtain the...

  • Toward wave energy in Oregon : predicting wave conditions and extracted power

    Creator:
    Oskamp, Jeffrey A.
    Abstract:
    Knowledge of wave conditions in nearshore regions supports the development of ocean wave energy technology by providing wave climatology for device design considerations, and power output estimates. By modeling wave transformation over the continental shelf, wave conditions were predicted in nearshore regions where potential wave energy conversion sites are located....

  • Large scale model testing of the FMC submerged wave attenuation device

    Creator:
    Huber, David S.
    Abstract:
    This report describes the hydrodynamic testing and evaluation of a one-tenth scale model of the FMC Wave Attenuation Device. The purpose of the test was to quantify the wave attenuation characteristics and structural loading induced by a test program of monochromatic incident waves on the submerged structure. The device was...

  • Flow visualization for wake formation under solitary wave flow

    Creator:
    Seiffert, Betsy Rose
    Abstract:
    The use of data extracted from particle image velocimetry (PIV) along with vector and tensor visualization techniques provides a valuable tool for understanding a complex flow field. By studying a simple geometric structure such as a cylinder under a simple transient waveform, fundamental mechanisms of wake development under solitary wave...

  • The static and cyclic pullout behavior of plate anchors in fine saturated sand

    Creator:
    Petereit, Ralph A.
    Abstract:
    Anchors resistant to tensile loads are commonly used in civil engineering practice. Anchors in the marine environment are most frequently used for the mooring of vessels. Only recently, with the expansion of the offshore industry, has the need to develop more reliable anchor systems become necessary. Embedded plate anchors are...

  • Wave field patterns generated by wave energy converters

    Creator:
    McNatt, J. Cameron
    Abstract:
    The eventual deployment of wave energy converters (WECs) on a commercial scale will necessitate the grouping of devices into arrays or "wave farms," in order to minimize overhead costs of mooring, maintenance, installation, and electrical cabling for shoreward power delivery. Closely spaced WECs will interact hydrodynamically through diffracted and radiated...

  • Use of benthic sediments as indicators of marina flushing

    Creator:
    Noble, Scott Morgan
    Abstract:
    This report presents the findings of a sediment analysis program formulated to determine the flushing potential of various shaped small boat marina basins. Chemical tests regarding volatile solids, Kjeldahl nitrogen, grease and oil, and sulfides were performed with the results compared to established sediment quality criteria. These results were used...

  • Airphoto analysis of estuarine circulation

    Creator:
    Weise, Harry Gordon
    Abstract:
    Aerial photography has become a valuable method of acquiring information on estuarine current circulation patterns. The method provides a comprehensive picture of nearly simultaneous surface water movements. It represents a significant improvement over conventional surface float and current meter methods because large areas may be covered in great detail with...
