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).

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 A Laboratory Study of Wind Wave Current Interactions Part I written by and published by . This book was released on 1975 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two series of experiments were performed to study the interactions between both the wind-induced drift layer and the surface wave spectrum and a spatially varying subsurface current field. In the first, measurements were made of the response of the drift layer and surface wave spectrum to an appreciable, but unknown, current gradient. This was accomplished by forcing the current from a 90 cm-deep diffuser section onto a 68.7 cm-deep flat beach. The flow, thereby, experienced a current gradient which diminished to, and remained essentially at, zero a short distance downstream of the beach leading edge. Relaxation times inferred from the data are on the order of 1 to 3 minutes. For the second test series, the beach was set at an angle of 2.65 deg to produce strain rates. Here again, the results indicate that the response of the drift layer lags behind that of the current, as strained by the beach. The measurements of surface wave spectra taken for each of the conditions tested are presently being analyzed in detail; however, some preliminary results are presented.

Book excerpt: It is confirmed that the velocity distribution essentially follows the logarithmic law near the water surface and the velocity-defect law toward the outer edge of the boundary layer. Calculated from these distributions, the wind stresses and surface roughnesses are divided into two groups separated by the occurrence of wave-breaking phenomenon. For sufficiently low wind velocity, U, the surface roughness is dictated by ripples and the wind-stress coefficient varies with U to the -1/2 power. The average height of the basic gravity wave is proportional to the surface roughness at higher wind velocities; the stress coefficient is then proportional to U. In addition, it is found that the Charnock's expression holds only at high wind velocities, and that the constant of proportionality determined from the experiment correlates very well with the field observations. Finally, the wind-stress coefficient is shown to be larger than the friction coefficient for turbulent flow along a solid rough surface; the difference is shown to be the wave drag of the wind over the water surface.

Download or read book Shock Wave Boundary Layer Interactions written by Holger Babinsky and published by Cambridge University Press. This book was released on 2011-09-12 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines. SBLIs have the potential to pose serious problems in a flowfield; hence they often prove to be a critical - or even design limiting - issue for many aerospace applications. This is the first book devoted solely to a comprehensive, state-of-the-art explanation of this phenomenon. It includes a description of the basic fluid mechanics of SBLIs plus contributions from leading international experts who share their insight into their physics and the impact they have in practical flow situations. This book is for practitioners and graduate students in aerodynamics who wish to familiarize themselves with all aspects of SBLI flows. It is a valuable resource for specialists because it compiles experimental, computational and theoretical knowledge in one place.
