Download or read book Ocean and Ship Wave Modification by a Surface Wake Flow Pattern written by O. M. Griffin and published by . This book was released on 1988 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean surface waves are altered by interactions with mean and fluctuating surface currents. These waves may be ambient or ship-generated, or may be a combined system produced by both sources of generation. An important wave-current interaction is caused by the interaction of the waves with the surface wake produced by the passage of a surface ship. Remote observations of a ship wake using synthetic aperture radar (SAR) show distinct features such as a dark trailing centerline region and bright-line images aligned at some angle to the ship's path. The dark region of relatively low radar backscatter is usually associated with a 'dead winter' region which is relatively devoid of short wave components, while the bright line feature suggests a region of enhanced radar return within the apparent angular confines of the ship's Kelvin wave pattern. In this report the interactions of ship generated Kelvin waves and ambient waves with the momentum wake of a surface vessel are studied to assess the effectiveness of the momentum wake in the generation of these remotely-observed features. Other factors such as the limiting wave steepness at the onset of wave breaking also are considered. Keywords: Ocean waves, Wake detection, Marine hydrodynamics, Wake, Ship waves. (JHD).

Download or read book Ambient Free Surface Wave Modification by a Submerged Vortex Pair written by Scott Fish and published by . This book was released on 1989 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research examines how free surface gravity waves travelling over a fluid are modified by the presence of a submerged pair of vortex singularities. The understanding of vortex flows near a free surface has become goal in the hydrodynamics community over the last decade due to its possible importance in determining the influence of vortical ship wakes on radar images of the ocean surface, a theory for vortical influence on ambient free surface waves has not been addressed. The inclusion of ambient surface wave modification by submerged vortices are taken by concentrating on three questions. First, what is the important physical mechanism of influence of the vortex on free surface ambient waves? Second, in formulating a typical vortex model of the flow involving a rising pair, what parameters are significant in determining the form of the ambient wave modification? And finally, how can this information be useful in the practical problem of radar imaging of ship wakes? Careful analytic analysis of the free surface boundary conditions will show that the induced surface current generated by the vortices provides the physical mechanism of ambient wave modification. A numerical model is described which is utilized to determine the relative importance of parameters derived in the analytic analysis on this physical mechanism. In addition, spectral analysis is performed to highlight the use of simulation results in evaluation of conditions applicable to the problem of radar remote sensing of ship wakes.

Available in PDF, EPUB and Kindle. Book excerpt: This new edition introduces the fundamentals of passive microwave remote sensing of oceans, including the physical principles of microwave radiometry, novel observational data, their interpretation, and applications. It not only demonstrates and examines the recent advantages and state of the art of microwave data but also provides guidance for explaining complex ocean studies and advanced applications. All chapters are thoroughly updated with detailed analysis of space‐based microwave missions, and a new chapter on space‐based microwave radiometer experiments has been added. This book discusses the power of microwave remote sensing as an efficient tool for diagnostics of ocean phenomena in research and education. Features New to this Edition: • Includes a new chapter and additional data, images, illustrations, and references. • Uses ocean microwave data, acquired from different platforms, to illustrate different methods of analysis and interpretation. • Updates information on recent and important satellite missions dedicated to microwave remote sensing of oceans. • Offers more detailed analysis of multiband microwave data and images. • Provides examples of microwave data that cover different ocean environmental phenomena and hydro‐physical fields, including global and local ocean features. • Presents additional material on advanced applications, including detection capabilities. This book is intended for postgraduate students and professionals working in fields related to remote sensing, geography, oceanography, civil, environmental, and geotechnical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Ship Hydrodynamics: Fluid Mechanics, Ship Resistance and Propulsion Lothar Birk, University of New Orleans, USA Bridging the information gap between fluid mechanics and ship hydrodynamics Fundamentals of Ship Hydrodynamics is designed as a textbook for undergraduate education in ship resistance and propulsion. The book provides connections between basic training in calculus and fluid mechanics and the application of hydrodynamics in daily ship design practice. Based on a foundation in fluid mechanics, the origin, use, and limitations of experimental and computational procedures for resistance and propulsion estimates are explained. The book is subdivided into sixty chapters, providing background material for individual lectures. The unabridged treatment of equations and the extensive use of figures and examples enable students to study details at their own pace. Key features: • Covers the range from basic fluid mechanics to applied ship hydrodynamics. • Subdivided into 60 succinct chapters. • In-depth coverage of material enables self-study. • Around 250 figures and tables. Fundamentals of Ship Hydrodynamics is essential reading for students and staff of naval architecture, ocean engineering, and applied physics. The book is also useful for practicing naval architects and engineers who wish to brush up on the basics, prepare for a licensing exam, or expand their knowledge.
