An eigenvalue wave analysis of a fixed semi-immersed rectangular structure

Creator:: Steimer, Robert Bruce
Abstract:: The problem of a fixed rectangular structure of unit width in a train of simple harmonic normally-incident waves is modeled. The solution allows for variable (1) length and draft of structure, (2) differing depths in the three (fore, aft, and beneath the structure) distinct regions, and (3) wave period. The...

Nonlinear diffraction theory by an eigenfunction expansion of the Green's function

Creator:: Chen, Min-Chu
Abstract:: A second-order nonlinear diffraction theory is developed for a large diameter circular cylinder under the action of surface gravity waves of finite amplitude in water of-finite depth. Boundary value problems are derived by using a perturbation expansion and the solutions for the diffracted waves are given in terms of Fredholm...

Random wave velocity field from periodic theory

Creator:: Kobune, Koji
Abstract:: Random waves are often expressed as a mathematical superposition of an infinite number of sinusoidal components. The mean square spectral density of the water surface elevation is often called the wave spectrum. The zero upcrossing wave heights usually have a Rayleigh probability distribution. However, the design wave concept is still...

A numerical model for predicting energy dispersion in thermal plumes issuing from large, vertical outfalls in shallow coastal water

Creator:: Trent, Donald S.
Abstract:: A theoretical study of the heat and momentum transfer resulting from a flow of power plant condenser effluent discharged vertically to shallow, quiescent coastal receiving water is presented. The complete partial differential equations governing steady, incompressible, turbulent flow driven by both initial momentum and buoyancy are solved using finite-difference techniques...

The use of electromagnetic Walsh waves in radar

Creator:: Schaffer, Alvin
Abstract:: The question of the suitability of Walsh functions or similar bi-valued functions used as a radar electromagnetic carrier waveform is considered. Walsh functions are described and effective sinusoidal steady state transfer functions are defined for transmission elements, antenna systems, and propagation media. The argument is made that the unit impulse...

The static and dynamic analysis of discretely represented moorings and cables by numerical means

Creator:: Dominguez, Richard Frank
Abstract:: Computer oriented techniques and procedures are presented for the analysis of single and multiple cable systems. Application is made to a two-point mooring system influenced by surface and subsurface hydrodynamic loading. The effects of the various parameters are presented and the numerical method is compared to exact solutions obtained from...

Design and calibration of a deep ocean nuclear moisture meter

Creator:: Hurley, James Leo
Abstract:: A prototype deep ocean nuclear moisture meter was developed based on the detection of epithermal neutrons backscattered from marine sediment molecules. Development consisted of choosing a source, a detector, containment materials, and associated counting equipment, followed by the construction and calibration of the probe. Thermal neutron response of the probe...
