Download or read book Air Entrainment in Free surface Flow written by I.R. Wood and published by Routledge. This book was released on 2018-04-24 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is aimed at the practising hydraulic engineer. Work on it commenced at Professor Naudascher's instigation in 1982. Over the next six years all or some of the authors discussed progress at IAHR sponsored conferences at Esslingen, Melbourne, Lausanne and Beijing. With the authors scattered throughout the world, and all with other responsibilities, progress was bound to be slow. Completion was further delayed by the great increase in published technical literature in this area over the period 1982-1988. This literature continues to expand and with it our understanding of the air water flow phenomena. The monograph must therefore be seen as the authors' views on the state of the art around 1988. More recent references have been included for completeness.This monograph has been a joint effort with most authors making suggestions and contributions to more than one chapter. Nevertheless, the chapter authors are primarily responsible for the material in their chapters.Throughout the monograph symbols are defined when they are fist introduced and a list of symbols is included at the end of each chapter.Many other people have contributed to this monograph, but the authors would particularly like to acknowledge the assistance given by Professor John McNown who has read, commented on and improved the style of the complete monograph.
Download or read book Fluid Mechanics of Environmental Interfaces Second Edition written by Carlo Gualtieri and published by CRC Press. This book was released on 2012-11-21 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Fluid Mechanics (EFM) studies the motion of air and water at several different scales, the fate and transport of species carried along by these fluids, and the interactions among those flows and geological, biological, and engineered systems. EFM emerged some decades ago as a response to the need for tools to study problems of flow and transport in rivers, estuaries, lakes, groundwater and the atmosphere; it is a topic of increasing importance for decision makers, engineers, and researchers alike. The second edition of the successful textbook "Fluid Mechanics of Environmental Interfaces" is still aimed at providing a comprehensive overview of fluid mechanical processes occurring at the different interfaces existing in the realm of EFM, such as the air-water interface, the air-land interface, the water-sediment interface, the surface water-groundwater interface, the water-vegetation interface, and the water-biological systems interface. Across any of these interfaces mass, momentum, and heat are exchanged through different fluid mechanical processes over various spatial and temporal scales. In this second edition, the unique feature of this book, considering all the topics from the point of view of the concept of environmental interface, was maintained while the chapters were updated and five new chapters have been added to significantly enlarge the coverage of the subject area. The book starts with a chapter introducing the concept of EFM and its scope, scales, processes and systems. Then, the book is structured in three parts with fifteen chapters. Part one, which is composed of four chapters, covers the processes occurring at the interfaces between the atmosphere and the surface of the land and the seas, including the transport of dust and the dispersion of passive substances within the atmosphere. Part two deals in five chapters with the fluid mechanics at the air-water interface at small scales and sediment-water interface, including the advective diffusion of air bubbles, the hyporheic exchange and the tidal bores. Finally, part three discusses in six chapters the processes at the interfaces between fluids and biotic systems, such as transport processes in the soil-vegetation-lower atmosphere system, turbulence and wind above and within the forest canopy, flow and mass transport in vegetated open channels, transport processes to and from benthic plants and animals and coupling between interacting environmental interfaces. Each chapter has an educational part, which is structured in four sections: a synopsis of the chapter, a list of keywords that the reader should have encountered in the chapter, a list of questions and a list of unsolved problems related to the topics covered by the chapter. The book will be of interest to graduate students and researchers in environmental sciences, civil engineering and environmental engineering, (geo)physics, atmospheric science, meteorology, limnology, oceanography, and applied mathematics.
Download or read book Air Bubble Entrainment in Free Surface Turbulent Shear Flows written by Hubert Chanson and published by Elsevier. This book was released on 1996-10-11 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book develops an analysis of the air entrainment processes in free-surface flows. These flows are investigated as homogeneous mixtures with variable density. Several types of air-water free-surface flows are studied: plunging jet flows, open channel flows, and turbulent water jets discharging into air. Experimental observations reported by the author confirm the concept that the air-water mixture behaves as a homogeneous compressible fluid in each case. This book will be of great interest to professionals working in many fields of engineering: chemical, civil, environmental, mechanical, mining, metallurgy, and nuclear. Covers new information on the air-water flow field: air bubble distributions, air-water velocity profiles, air bubble sizes and bubble-turbulence interactions Features new analysis is developed for each flow configuration and compared successfully with model and prototype data Includes over 372 references and more than 170 figures with over 60 photographs Presents useful information for design engineers and research-and-development scientists who require a better understanding of the fluid mechanics of air-water flows

Available in PDF, EPUB and Kindle. Book excerpt: Water. Except for air, it is the most important ingredient to all life on Earth. It surrounds us every day. We are literally bathed in it, we cook our food with it, and we need a steady stream of it in our bodies every single day just to survive. But water, and the study of it, is one of the most important and unheralded branches of engineering, affecting every other aspect of engineering in almost every industry. We harness its power for energy, we inject massive blasts of it into the earth to extract oil, gas, and minerals, and we use it in nearly every single industrial application, including food processing, refining, manufacturing, and waste disposal, just to name a few. Hyraulic modeling is, essentially, the understanding and prediction of fluid flow and its applications in industrial, municipal, and environmental settings, whether in a creekbed, locked in the pores of rocks deep in the earth, or in the ocean. Mathematical models, which started out with mechanical pencils and drafting tables originally, have been increasingly relied upon over the last few decades, due to the invention, growth, and refinement of computers. Physical modeling, however, is still practiced in laboratories, and it is the intersection of physical and mathematical modeling of fluid flow that is most successful in creating models that are safer, less costly, and are better for the environment. Hydraulic Modeling introduces and explores this incredibly important science, from the most basic tenets to valuable real-world applications that are used in industry today. It is the only volume on the market to offer a thorough coverage of the subject without adding lots of useless fluff or inapplicable appendices. It is a must-have for any engineer, scientist, or student working with hydraulic modeling, as a daily reference or a textbook.
Download or read book Gas Transfer at Water Surfaces written by W. Brutsaert and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transfer across the surface of environmental waters is of interest as an important phase in the geophysical and natural biochemical cycles of numer ous substances; indeed it governs the transition, one way or the other, be tween the dissolved state in the water and the gaseous state in the atmo sphere. Especially with increasing population and industrialization, gas transfer at water surfaces has become a critical factor in the understanding of the various pathways of wastes in the environment and of their engineering management. This interfacial mass transfer is, by its very nature, highly complex. The air and the water are usually in turbulent motion, and the interface be tween them is irregular, and disturbed by waves, sometimes accompanied by breaking, spray and bubble formation. Thus the transfer involves a wide variety of physical phenomena occurring over a wide range of scales. As a consequence, scientists and engineers from diverse disciplines and problem areas, have approached the problem, often with greatly differing analytical and experimental techniques and methodologies.

Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic engineering of dams and their appurtenant structures counts among the essential tasks to successfully design safe water-retaining reservoirs for hydroelectric power generation, flood retention, and irrigation and water supply demands. In view of climate change, especially dams and reservoirs, among other water infrastructure, will and have to play an even more important role than in the past as part of necessary mitigation and adaptation measures to satisfy vital needs in water supply, renewable energy and food worldwide as expressed in the Sustainable Development Goals of the United Nations. This book deals with the major hydraulic aspects of dam engineering considering recent developments in research and construction, namely overflow, conveyance and dissipations structures of spillways, river diversion facilities during construction, bottom and low-level outlets as well as intake structures. Furthermore, the book covers reservoir sedimentation, impulse waves and dambreak waves, which are relevant topics in view of sustainable and safe operation of reservoirs. The book is richly illustrated with photographs, highlighting the various appurtenant structures of dams addressed in the book chapters, as well as figures and diagrams showing important relations among the governing parameters of a certain phenomenon. An extensive literature review along with an updated bibliography complete this book.
