Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was made to determine the ratio of the wave-supported shear stress, phi sub w; to the total shear stress on the water surface, phi sub o. The experimental conditions were designed to correspond to those required for the application of the viscous shear flow theory of wave generation proposed by Brooke Benjamin (1959) and Miles (1962b). The experiments were performed in a wind-wave tunnel, 48 x 3-1/2 x 2 feet, with a mean water depth of 1-1/2 feet. The wind in the 6 in. air space above the water was fully-developed turbulent channel flow. The mean center-line wind speed, U sub xi, was kept constant at 1.20 m/s during all measurements made with the wind blowing over the water. An artificially generated, single-component, wave train of small amplitude provided a known, initial perturbation of the water surface with which the wind could interact. The range of wave frequencies investigated was from 4.0 to 5.2 cps. Wave measurements were made with capacitance wave probes, wind measurements with hot-wire anemometers. (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.

Download or read book An Experimental Investigation of the Structure of a Turbulent Wind Over Water Waves written by Susumu Karaki and published by . This book was released on 1968 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation presents experimental results from a study of the structure of a turbulent boundary layer developed by air flow over water waves in a lab wind-wave channel. It was demonstrated that the sheared flow region is two-layered, similar to rough wall boundary layers. The inner layer, adjacent to the wall, is describable by the 'law of the wall' and the outer flow by the 'defect law.' The data were taken in two-dimensional flow with small favorable pressure gradients. The first part of the two-part investigation involved air flow over an initially still water surface on which waves developed in response to wind excitation. In the second part, air was passed over water waves of a single frequency and varied amplitude. The results indicated that within the range of this study the water surface can be classed as aerodynamically rough at wind speeds greater than 12 fps and the flow structure of the boundary layer corresponds to that over a rough wall. The velocity decrement due to surface roughness is shown to be a function of the local root-mean-square wave height. The effect of wave-induced fluctuations in the air is limited to a very close neighborhood of the wavy surface. For the specific combination of wind and wave speeds of this study it was found that while the amplitudes of the horizontal components of the fluctuation decreased with increasing elevation, the vertical component increased.

Download or read book Oceanographical Engineering written by Robert L. Wiegel and published by Courier Corporation. This book was released on 2013-09-03 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: As is the case with many modern fields of study, oceanographical engineering cuts across the boundaries of several disciplines. Like other scientific endeavors, it aims to understand the nature of the ocean and to make use of this understanding for the benefit of humanity through better ports, safer and more economical operations at sea, and greater use of the oceans' natural resources--food, raw materials, and recreation. This graduate-level text requires a knowledge of fluid mechanics; a background in the motions of sediments in fluids is advisable, as is a concurrent course in structural dynamics. Topics include the theory of periodic waves; tsunamis, storm surges, and harbor oscillations; the effect of structures on waves; waves in shoaling water; tides and sea level changes; currents; shores and shore processes; some characteristics of the oceans' waters; moorings; and other related subjects. Certain portions of the book pertaining to the distribution of temperatures and salinities in the ocean are largely descriptive; other portions, such as the sections on waves, are mathematical. Numerous drawings and photographs supplement the text.
Download or read book Breaking and Dissipation of Ocean Surface Waves written by Alexander Babanin and published by Cambridge University Press. This book was released on 2011-05-19 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wave breaking represents one of the most interesting and challenging problems for fluid mechanics and physical oceanography. Over the last fifteen years our understanding has undergone a dramatic leap forward, and wave breaking has emerged as a process whose physics is clarified and quantified. Ocean wave breaking plays the primary role in the air-sea exchange of momentum, mass and heat, and it is of significant importance for ocean remote sensing, coastal and ocean engineering, navigation and other practical applications. This book outlines the state of the art in our understanding of wave breaking and presents the main outstanding problems. It is a valuable resource for anyone interested in this topic, including researchers, modellers, forecasters, engineers and graduate students in physical oceanography, meteorology and ocean engineering.
