Download or read book Bubble Injection Under Breaking Waves written by James B. Tannahill and published by . This book was released on 1996 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wave energy dissipation due to bubble penetration and inferred turbulent penetration from breaking waves in the surf zone is related to the total energy of dissipation. Bubble injection is inferred from void fraction measurements obtained using a 2.3 meter vertical array of eight conductivity sensors extending from the bottom through the water surface. Potential energy and dissipation associated with bubble injection are calculated and compared with total wave dissipation. Total wave dissipation is calculated from the energy flux balance measured using an array of seven pressure sensors in the surf zone. Percent of total wave potential energy of the bubbles due to spilling breakers is on the order of 0.18% to 0.62%, consistent with past measurements in the surf zone. Percent of the bubble potential energy dissipation rates to total wave dissipation in the cross shore direction is on the order of 8% to 20%. The potential energy dissipation is largest immediately after injection, decaying exponentially after that. Bubble potential energy dissipation results within 1.2 seconds even for void fraction events greater than 36% and usually in less than 1.0 seconds. Energy dissipation was found linearly related (0.95 correlation coefficient) with the ratios of wave height to water depth, a measure of the percent of breaking waves within the surf zone.
Download or read book Void Fraction Under Breaking Waves written by R. J. Piret and published by . This book was released on 1999 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bubble injection due to breaking waves within the surf zone is inferred by measuring void fraction using a 3 m vertical array of eight conductivity cells in conjunction with video pixel intensity. Void fraction errors associated with the conductivity measurements are examined, including vertical variations in the temperature and conductivity (measured), proximity effects near the surface, and estimates of the surface elevation using pressure sensors. Energy loss is due to conversion of kinetic and potential energy of a wave to buoyant potential energy by the injection of air into the water column, which is then lost as the bubbles raise to the surface and escape to the atmosphere. Void fractions up to 40% were observed in intense breaking events penetrating to depths over 0.5 m confined within the crest trough region. Production of potential energy due to buoyancy of bubbles was nearly instantaneous with the majority of energy dissipating within 0.25 s. Pixel intensity qualitatively correlated with surface elevation and injection events. Crests in cross shore intensity time stack plots are clearly visible and show good correlation with breaking events. However, pixel intensity values did not correlate quantitatively with surface elevation or production of buoyant potential energy.

Download or read book Sea Salt Aerosol Production written by Ernie R. Lewis and published by American Geophysical Union. This book was released on 2004-01-09 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 152. Sea salt aerosol (SSA) exerts a major influence over a broad reach of geophysics. It is important to the physics and chemistry of the marine atmosphere and to marine geochemistry and biogeochemistry generally. It affects visibility, remote sensing, atmospheric chemistry, and air quality. Sea salt aerosol particles interact with other atmospheric gaseous and aerosol constituents by acting as sinks for condensable gases and suppressing new particle formation, thus influencing the size distribution of these other aerosols and more broadly influencing the geochemical cycles of substances with which they interact. As the key aerosol constituent over much of Earth's surface at present, and all the more so in pre-industrial times, SSA is central to description of Earth's aerosol burden.

Download or read book Color of Inland and Coastal Waters written by Dmitry Pozdnyakov and published by Springer Science & Business Media. This book was released on 2003-01-31 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inorganic and organic water constituents, often called color-producing agents (CPAs), responsible for water color are generally referred to as water quality parameters. Utilization of water color for assessment of water quality parameters can be achieved by using the established techniques in aquatic optics attained over many decades. Aquatic optics can be subdivided according to whether the natural water body is salty (marine), inland or fresh (limnological), or coastal (often brackish). The authors describe the transformation of water color under varying natural and anthropogenically-driven conditions and, for the first time in a quantitative manner, a closed circle of issues related to remote sensing of water quality in optically complex waters generally inherent to inland and marine coastal waters. Primarily, the text synthesizes the solutions of problems in remote sensing, incorporating mathematics, hydrobiology/hydochemistry, atmospheric optics and ecology.

Download or read book The Acoustic Bubble written by T Leighton and published by Academic Press. This book was released on 2012-12-02 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Acoustic Bubble describes the interaction of acoustic fields with bubbles in liquid. The book consists of five chapters. Chapter 1 provides a basic introduction to acoustics, including some of the more esoteric phenomena that can be seen when high-frequency high-intensity underwater sound is employed. Chapter 2 discusses the nucleation of cavitation and basic fluid dynamics, while Chapter 3 draws together the acoustics and bubble dynamics to discuss the free oscillation of a bubble and acoustic emissions from such activity. The acoustic probes that are often applied to study the behavior of a bubble when an externally-applied acoustic field drives it into oscillation is deliberated in Chapter 4. The last chapter outlines a variety of effects associated with acoustically-induced bubble activity. The bubble detection, sonoluminescence, sonochemistry, and pulse enhancement are also covered. This publication is a good reference for physics and engineering students and researchers intending to acquire knowledge of the acoustic interactions of acoustic fields with bubbles.

Download or read book Propagation Modeling for Wireless Communications written by Indrakshi Dey and published by CRC Press. This book was released on 2022-05-03 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the various approaches and tools used for modelling different propagation environments and lays the foundation for developing a unified theoretical framework for future integrated communication networks. In the case of each type of network, the book uses basic concepts of physics, mathematics, geometry and probability theory to study the impact of the dimension and shape of the propagation environment and relative transmit-receive position on the information flow. The book provides an introduction into wireless communication systems and networks and their applications. For both systems and networks, the basic hard (encoder, modulator, etc.) and soft components (information, signal, etc.) are discussed through schematic block diagrams. Next each of the modes of communication, namely radio waves, acoustic waves, magnetic induction, optical waves, biological particles (molecules, aerosols, neural synapse etc.) and quantum field, are discussed. For each communication scenario presented, the impact of different environmental factors on the propagation phenomenon is articulated, followed by different channel modelling (deterministic, analytical, and stochastic) techniques that are used to characterize the propagation environment. Finally future trends in wireless communication networks are examined and envisioned for next generations 6G/7G of communication systems, like space information networks, sea-to-sky internet of vehicles, and internet of bio-nano things. Based on the future trends of integrated networks, the book drives the need for a generalized channel model irrespective of the media and mode of information transfer. The primary audience for the book is post-graduate students, researchers and academics in electronics and communications engineering, electrical engineering and computer science.

This book was released on 1996-01-11 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding and constructively using natural sound in the ocean has become of prime importance with the shift of emphasis to protecting the environment and exercising responsible global resource management which has followed the end of the Cold War. Especially now that we realise that marine mammals and other inhabitants of the oceans are threatened by our acoustic pollution of their environment, the use of natural sound as a non-intrusive remote sensing probe has become particularly germane. This was the first meeting on the subject since the fall of Soviet-Western barriers, and the proceedings include significant work from premier researchers in the former Soviet Union. It was also the first meeting which specifically addressed the new and exciting idea of using natural sound in applications for monitoring the marine environment. The proceedings include a number of papers on various aspects of this topic. Further new work on the basic physics of sound production and propagation is also included. This volume includes leading-edge work from the foremost researchers in the field, including Bill Carey, Lawrence Crum, Nikolai Dubrovskii, David Farmer, Brian Kerman, Bill Kuperman, Michael Longuet-Higgins, Hank Medwin, Ken Melville, A Prosperetti and many others.
