Dynamics of single point ocean moorings of a buoy--a numerical model for solution by computer

Creator:: Nath, John H.
Abstract:: A numerical model was developed which predicts the dynamic response of a single mooring line and a buoy of forty feet diameter to sinusoidal waves, wind and current in all deep waters. All forces and reactions were considered to be in one plane. The basic equations for the mooring line...

Random wave forces on cylinders

Creator:: Hsu, Ming-kuang
Abstract:: The in-line force power spectrum is predicted by the frequency domain maximum force coefficient [C[subscript μn](z,f[subscript n])] vs. Keulegan-Carpenter number [K[subscript n] (z,f[subscript n])] relationship. The frequency domain Keulegan- Carpenter number is defined as the velocity from the amplitude spectrum at f divided by the respective frequency and diameter of...

Hydrodynamic forces on a horizontal cylinder under waves and current

Creator:: Teng, Chung-chu
Abstract:: 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...

Large displacement, high Reynolds number oscillating cylinder

Creator:: Chan, Yau Wai
Abstract:: Hydrodynamic forces on a cylinder oscillating horizontally underwater with its axis perpendicular to the motion were measured at the Oregon State University Wave Research Facility. The cylinder had an outer diameter of 12 inches and a length of 12 feet. For the data presented herein, the maximum displacement of the...

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...

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...
