Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose of this work was to study the response of gravity water waves to wind excitation, and in particular the applicability of the Miles inviscid shear-flow theory of gravity wave growth, by conducting experiments in a laboratory wind-wave channel under conditions approximating the assumptions of the mathematical model. The secondary objective was to document features of the coupled wave-response/wind-excitation system for comparison with the assumptions of Miles' theory. Mechanically generated wave profiles were measured with capacitance wire sensors and wave energy was calculated at seven stations spaced at 10-ft intervals along the channel test section. Waves varied in length from about 2.5 to 6.5 ft and maximum wind speeds ranged from 12 to 44 fps. Two sources of evidence indicate that without some modification the Miles inviscid theory may be inapplicable to gravity wave growth on a sufficiently rough water surface. First, the measured growth rates were significantly larger than theory predicts. Second, the superposed ripple standard deviations were larger than the respective critical layer thicknesses. Measured energy growth is not inconsistent with the energy transfer expected from flow separation. (Author).
Download or read book The Interaction of Ocean Waves and Wind written by Peter Janssen and published by Cambridge University Press. This book was released on 2004-10-28 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was published in 2004. The Interaction of Ocean Waves and Wind describes in detail the two-way interaction between wind and ocean waves and shows how ocean waves affect weather forecasting on timescales of 5 to 90 days. Winds generate ocean waves, but at the same time airflow is modified due to the loss of energy and momentum to the waves; thus, momentum loss from the atmosphere to the ocean depends on the state of the waves. This volume discusses ocean wave evolution according to the energy balance equation. An extensive overview of nonlinear transfer is given, and as a by-product the role of four-wave interactions in the generation of extreme events, such as freak waves, is discussed. Effects on ocean circulation are described. Coupled ocean-wave, atmosphere modelling gives improved weather and wave forecasts. This volume will interest ocean wave modellers, physicists and applied mathematicians, and engineers interested in shipping and coastal protection.

This book was released on 2012-12-06 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: A primary aim of the NATO Science Committee since its estab lishment in 1958 has been to· further international scientific co operation among scientists from the member countries of the Alliance. Almost all fields of basic science have received sub stantial support for the purposes of enhancing exchange of inform ation, providing opportunities for advanced instruction and collaborative research. Up to 1977, more than 10,000 fellowships have been awarded to allow scientists to complete their scientific education in another country and more than 1,500 joint research projects involving scientists in at least two different countries per project have been financed by the Committee. In addition, more than 800 advanced study institutes have been held under NATO auspices which have allowed more than sixty thousand scientists to get together to hear leading scientists lecture on advanced research topics on the frontier of research of many disciplines and to discuss the most recent results of their research activi ties. The Science Committee also identifies specific areas as deserving special encouragement or preferential support for limited periods. A variety of mechanisms - research grants, study visits, conferences, etc. - is utilized to stimulate greater international activity. This effort is embodied in several individual programmes, each guided by a special programme panel of internationally eminent experts. Air-sea interaction is one of these programmes.
Download or read book Stratified Flows written by Chia-Shun Yih and published by Elsevier. This book was released on 2012-12-02 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stratified Flows is the second edition of the book Dynamics of Nonhomogenous Fluids. This book discusses the flow of a fluid of variable density or entropy in a gravitational field. In this edition, corrections have been made; unnecessary parts have been omitted; and new sections as well as notes on results related to the subject have been added. This book includes a general discussion of the effects of density or entropy and the structure of stratified flows; waves of small amplitude; the Eigenvalue problem; dependence of phase velocity on wavelength; wave motion; steady flows of finite amplitude; and types of solutions for steady flows. This edition also covers other topics such as hydrodynamic stability; flows in porous media; and the analogy between gravitational and electromagnetic forces. This text is recommended for those in the field of physics who would like to be familiarized with stratified flows and its related concepts.
Download or read book Internal Gravity Waves written by Bruce R. Sutherland and published by Cambridge University Press. This book was released on 2010-09-02 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of internal gravity waves provides many challenges: they move along interfaces as well as in fully three-dimensional space, at relatively fast temporal and small spatial scales, making them difficult to observe and resolve in weather and climate models. Solving the equations describing their evolution poses various mathematical challenges associated with singular boundary value problems and large amplitude dynamics. This book provides the first comprehensive treatment of the theory for small and large amplitude internal gravity waves. Over 120 schematics, numerical simulations and laboratory images illustrate the theory and mathematical techniques, and 130 exercises enable the reader to apply their understanding of the theory. This is an invaluable single resource for academic researchers and graduate students studying the motion of waves within the atmosphere and ocean, and also mathematicians, physicists and engineers interested in the properties of propagating, growing and breaking waves.
Download or read book Wind Over Wave Couplings written by S. G. Sajjadi and published by OUP Oxford. This book was released on 1999-04-29 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most familiar phenomena on the planet, water waves remain an elusive question for science. The way in which wind blows over water and causes waves is a very active area of research for applied mathematicians, as well as for oceanographers and engineers. The basic mechanisms are still a matter of controversy, although the use of modern techniques of asymptotic and non-linear analysis and large-scale computation, as well as experimental structures, are beginning to reveal the underlying mechanics. These studies are resulting in increasingly powerful methods of forecasting waves and of gauging and controlling their effects on such things as sediment, pollution, and offshore structures. This volume covers the wide range of current research on the relationship between wind and waves and includes contributions from many of the leading authorities in the field.
