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...

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...

Finite elements analysis of circular cell bulkheads

Creator:: Kittisatra, Likhit
Abstract:: A mathematical model is developed for the analysis of circular cell bulkheads subjected to gravity loads of cell fill, backfill, lateral pressure, and surcharge load using the finite element method. The finite element circular cell model consists of axisymmetric triangular and/or quadrilateral ring elements for soil and cylindrical shell elements...

An investigation of the feasibility of a cutbank slope design method based on the analysis of natural slopes

Creator:: Keener, Quentin Roosevelt
Abstract:: The failure of cutbanks is a major problem encountered by those who construct low-cost roads in naturally forested residual soils. Attempts have been made to lessen the severity of failures by classifying certain soil areas as to their susceptibility to failure, in addition to bringing past design experience into play...

Displacement response of transmission line conductors during random wind gusts

Creator:: Cameron, George Richardson
Abstract:: The mean square displacement response of a point on a transmission line conductor that is subjected to wind gust generated lift forces is computed. The wind gust velocity and wind gust generated lift forces are treated as random processes in both time and space. A lift force, that is velocity...

Modeling of ammonia losses in sprinkler application of animal wastes

Creator:: Pote, Jonathan W. (Jonathan Woodrome)
Abstract:: A model to predict ammonia losses from sprinkler applied animal wastes was developed; in order to accomplish this, a review of literature was performed to determine possible methods of predicting ammonia losses during sprinkling. As adaptability to a large variety of situations was considered of maximum importance, the number of...

Ambient current effects on vertical selective flow withdrawal in a two layer reservoir system

Creator:: Charbeneau, Randall Jay
Abstract:: Withdrawal from a two-layer flow field is examined in terms of the degree of selectivity of the withdrawal flow and its dependence on an ambient current. Selectivity is defined as the bias of withdrawing one layer more strongly than the other; the extreme' case is complete selective withdrawal, where one...

Finite amplitude deep water waves : a comparison of theoretical and experimental kinematics and dynamics

Creator:: Jensen, Robert E.
Abstract:: Problems associated with quantification of deep water wave kinematics and dynamics are examined. Summaries of Stokes' theory and Dean's stream function theory are reported. A computer algorithm is developed to solve the hydrodynamic characteristics for Stokes' fifth and third order and linear theories. Tests are initiated to verify the results...

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...
