An analytical model is developed to examine the response and
efficiency of a vertical rigid, hinged, floating breakwater. The
boundary value problem describing the flow field yields a well-posed
Sturm-Liouville problem which is solved by separation of variables
for the velocity potentials. The equation of breakwater motion about
the breakwater...
By assuming the linear superposition principle to be valid, the
hydrodynamic forces on a horizontal cylinder under waves and current
are examined. In this study, towing a cylinder in waves is used to
simulate a cylinder under waves and current. The experimental
technique is proved valid through theoretical considerations and...
Directional wave spectra have been estimated in this study based
upon simultaneous subsurface measurements of current and pressure.
Two previously developed methods, the stochastic and deterministic
approaches, have been reviewed and restudied. It is demonstrated by
means of the Correlation Theorem that the stochastic and deterministic
approaches are, under certain...
The objective of this study is the development and
verification of an analytical solution for an unsteady
flow field partially occupied by a permeable structure.
Flow is induced by a small amplitude incident wave
train and the permeable structure may contain multilayered
anisotropic but homogeneous material. The analytical
solution developed...
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...
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...
