Free-Surface Flow by Nikolaos D. Katopodes Pdf

Free Surface Flow: Environmental Fluid Mechanics introduces a wide range of environmental fluid flows, such as water waves, land runoff, channel flow, and effluent discharge. The book provides systematic analysis tools and basic skills for study fluid mechanics in natural and constructed environmental flows. As the prediction of changes in free surfaces in rivers, lakes, estuaries and in the ocean directly affects the design of structures that control surface waters, and because planning for the allocation of fresh-water resources in a sustainable manner is an essential goal, this book provides the necessary background and research. Helps users determine the transfer of solute mass through the air-water interface Presents tactics on the impact of free shear flow in the environment and how to quantify mixing mechanisms in turbulent jets and wakes Gives users tactics to predict the fate and transport of contaminants in stratified lakes and estuaries

Free-Surface Flow: by Nikolaos D. Katopodes Pdf

Free-Surface Flow: Shallow-Water Dynamics presents a novel approach to this phenomenon. It bridges the gap between traditional books on open-channel flow and analytical fluid mechanics. Shallow-water theory is established by formal integration of the Navier-Stokes equations, and boundary resistance is developed by a rigorous construction of turbulent flow models for channel flow. In addition, the book presents a comprehensive description of shallow-water waves by mathematical analysis. These methods form the foundation for understanding flood routing, sudden water releases, dam and levee break, sluice gate dynamics and wave-current interaction. Bridges the gap between traditional books on open-channel flow and wave mechanics. Presents a comprehensive description of shallow-water waves by characteristic and bicharacteristic analysis. Presents techniques for wave control and active flood mitigation.

Hydrodynamics of Free Surface Flows by Jean-Michel Hervouet Pdf

A definitive guide for accurate state-of-the-art modelling of free surface flows Understanding the dynamics of free surface flows is the starting point of many environmental studies, impact studies, and waterworks design. Typical applications, once the flows are known, are water quality, dam impact and safety, pollutant control, and sediment transport. These studies used to be done in the past with scale models, but these are now being replaced by numerical simulation performed by software suites called “hydro-informatic systems”. The Telemac system is the leading software package worldwide, and has been developed by Electricité de France and Jean-Michel Hervouet, who is the head and main developer of the Telemac project. Written by a leading authority on Computational Fluid Dynamics, the book aims to provide environmentalists, hydrologists, and engineers using hydro-informatic systems such as Telemac and the finite element method, with the knowledge of the basic principles, capabilities, different hypotheses, and limitations. In particular this book: presents the theory for understanding hydrodynamics through an extensive array of case studies such as tides, tsunamis, storm surges, floods, bores, dam break flood waves, density driven currents, hydraulic jumps, making this a principal reference on the topic gives a detailed examination and analysis of the notorious Malpasset dam failure includes a coherent description of finite elements in shallow water delivers a significant treatment of the state-of-the-art flow modelling techniques using Telemac, developed by Electricité de France provides the fundamental physics and theory of free surface flows to be utilised by courses on environmental flows Hydrodynamics of Free Surface Flows is essential reading for those involved in computational fluid dynamics and environmental impact assessments, as well as hydrologists, and bridge, coastal and dam engineers. Guiding readers from fundamental theory to the more advanced topics in the application of the finite element method and the Telemac System, this book is a key reference for a broad audience of students, lecturers, researchers and consultants, right through to the community of users of hydro-informatics systems.

Free-Surface Flow by Nikolaos D. Katopodes Pdf

Free-Surface Flow: Computational Methods presents a detailed analysis of numerical schemes for shallow-water waves. It includes practical applications for the numerical simulation of flow and transport in rivers and estuaries, the dam-break problem and overland flow. Closure models for turbulence, such as Reynolds-Averaged Navier-Stokes and Large Eddy Simulation are presented, coupling the aforementioned surface tracking techniques with environmental fluid dynamics. While many computer programs can solve the partial differential equations describing the dynamics of fluids, many are not capable of including free surfaces in their simulations. Provides numerical solutions of the turbulent Navier-Stokes equations in three space dimensions Includes closure models for turbulence, such as Reynolds-Averaged Navier-Stokes, and Large Eddy Simulation Practical applications are presented for the numerical simulation of flow and transport in rivers and estuaries, the dam-break problem and overland flow

Air Entrainment in Free-surface Flow by I.R. Wood Pdf

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.

Computer Modeling of Free-Surface and Pressurized Flows by M. Hanif Chaudhry,L. Mays Pdf

Computers are widely used for the analysis, design, and operation of water resource projects. This gives accurate results, allowing the analysis of complex systems which may not have been possible otherwise, and the investigation and comparison of several different alternatives in a short time, thereby reducing the project costs, optimizing design, and efficient utilization of resources. This volume compiles an edited version of the lecture notes specially prepared by 14 well-known European and North American researchers. Part I deals with free-surface flows. Governing equations are derived and their solution by the finite-difference, finite-element, and boundary-integral methods are discussed. Then, turbulence models, three-dimensional models, dam-break flow models, sediment transport models, and flood routing models are presented. Part II is related to the modeling of steady and transient pressurized flows. Governing equations for both single and two-component flows are derived and numerical methods for their solution are presented. The modeling of water quality in pipe networks, of cooling water systems, and slow and rapid transients is then discussed.

Transient Free Surface Flows in Building Drainage Systems by John Swaffield Pdf

Climate change will present a series of challenges to engineers concerned with the provision of both building internal appliance drainage networks and rainwater systems within the building boundary, generally identified as the connection to the sewer network. Climate change is now recognised as presenting both water shortage and enhanced rainfall design scenarios. In response to predictions about immanent climate change Transient Free Surface Flows in Building Drainage Systems addresses problems such as the reduction in water available to remove waste from buildings, and conversely, the increase in frequency of tropical-type torrential rain. Starting with introductory chapters that explain the theories and principles of solid transport, free surface flows within drainage networks, and attenuating appliance discharge flows, this book allows readers from a variety of backgrounds to fully engage with this crucial subject matter. Later chapters apply these theories to the design of sanitary and rainwater systems. Case studies highlight the applicability of the method in assessing the appropriateness of design approaches. In this unique book, research in modelling for free surface flows at Edinburgh’s Heriot-Watt University is drawn on to provide a highly authoritative, physics-based study of this complex engineering issue.

Free-Surface Hydraulics by Dr J M Townson Pdf

Free-Surface Hydraulics is a unified, pragmatic account of the water surface and its underlying mechanics. Based on the author's 30 years experience of research and teaching in civil engineering hydraulics, this text is designed to help students achieve a coherent understanding More...of a subject often obscured by empirical detail and unstructured approaches. The text leads progressively from hydrostatics, through steady and unsteady flows, to waves and tides. The author draws a careful distinction between kinematic and dynamic motions - the latter he treats at some length by the method of characteristics, regarded as one of the more rigorous approaches to unsteady flow. A special feature is the final chapter, devoted to the disruption of free surfaces by air and bubble motion, especially in pipes.

Conceptual Models of Flow and Transport in the Fractured Vadose Zone by National Research Council,Commission on Geosciences, Environment, and Resources,Board on Earth Sciences and Resources,U.S. National Committee for Rock Mechanics,Panel on Conceptual Models of Flow and Transport in the Fractured Vadose Zone Pdf

Fluid flow and solute transport within the vadose zone, the unsaturated zone between the land surface and the water table, can be the cause of expanded plumes arising from localized contaminant sources. An understanding of vadose zone processes is, therefore, an essential prerequisite for cost-effective contaminant remediation efforts. In addition, because such features are potential avenues for rapid transport of chemicals from contamination sources to the water table, the presence of fractures and other channel-like openings in the vadose zone poses a particularly significant problem, Conceptual Models of Flow and Transport in the Fractured Vadose Zone is based on the work of a panel established under the auspices of the U.S. National Committee for Rock Mechanics. It emphasizes the importance of conceptual models and goes on to review the conceptual model development, testing, and refinement processes. The book examines fluid flow and transport mechanisms, noting the difficulty of modeling solute transport, and identifies geochemical and environmental tracer data as important components of the modeling process. Finally, the book recommends several areas for continued research.

Air Bubble Entrainment in Free-Surface Turbulent Shear Flows by Hubert Chanson Pdf

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
