This book was released on 1981 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction of waves and currents and their relationship to the forces on submerged pipelines was investigated at Texas A&M University. A model pipeline in a wave-current test facility is used to obtain experimental force values which are compared to values predicted by various theoretical methods of representing wave propagation in a current. The Morison equation is employed to evaluate the forces on the horizontal cylinder. The major input parameters required by this equation are the water particle kinematics of velocity and acceleration and the coefficients of drag and inertia. Each of these parameters is investigated individually in order to ensure that compensating errors in the force calculations are eliminated. The coefficient of drag is determined from the simultaneous measurements of the horizontal water particle kinematics and the fluid force on the cylinder. Several wave theories for waves propagating in still water are modified to include currents by various combinations of their respective horizontal velocity fields. These water particle kinematics are compared directly to experimentally determined values. The measured forces are compared to the forces obtained by the Morison equation with the coefficients determined in this study and the kinematics predicted by the modified wave theories. The data are also compared to previous results for the individual cases of waves or currents. These comparisons demonstrate the changes of the coefficients of drag for the combined wave and current conditions. The primary purpose of this paper is not to provide explicit prototype design criteria, but to provide the design engineer with an insight into the fluid force parameters of interacting waves and currents. The results are presented in a manner that demonstrates the apparent acceptability of superimposing the velocity fields of the wave and current to predict the total velocity field for the determination of the fluid force by the Morison equation.

Download or read book Hydrodynamics Around Cylindrical Structures written by Jorgen Fredsoe and published by World Scientific. This book was released on 1997-03-17 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the subject of wave/current flow around a cylinder, the forces induced on the cylinder by the flow, and the vibration pattern of slender structures in a marine environment.The primary aim of the book is to describe the flow pattern and the resulting load which develops when waves or current meet a cylinder. Attention is paid to the special case of a circular cylinder. The development in the forces is related to the various flow patterns and is discussed in detail. Regular as well as irregular waves are considered, and special cases like wall proximities (pipelines) are also investigated.The book is intended for MSc students with some experience in basic fluid mechanics and for PhD students.

Book excerpt: The Twenty-Second Symposium on Naval Hydrodynamics was held in Washington, D.C., from August 9-14, 1998. It coincided with the 100th anniversary of the David Taylor Model Basin. This international symposium was organized jointly by the Office of Naval Research (Mechanics and Energy Conversion S&T Division), the National Research Council (Naval Studies Board), and the Naval Surface Warfare Center, Carderock Division (David Taylor Model Basin). This biennial symposium promotes the technical exchange of naval research developments of common interest to all the countries of the world. The forum encourages both formal and informal discussion of the presented papers, and the occasion provides an opportunity for direct communication between international peers.
