This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter deals with the processes by which a single-phase 3-D CFD model of hydrodynamics in a Sulejow dam reservoir was developed, verified, and tested. A simplified volume of fluid (VOF) model of flow was elaborated to determine the effect of wind on hydrodynamics in the lake. A hexahedral mesh with over 17 million elements and a k-ω SST turbulence model were defined for single-phase simulations in steady-state conditions. The model was verified on the basis of the extensive hydrodynamic measurements. Excellent agreement (average error of less than 10%) between computed and measured velocity profiles was found. The simulation results proved a strong effect of wind on hydrodynamics, especially on the development of the water circulation pattern in the lacustrine zone in the lake.

Book excerpt: Dams and their auxiliary structures are built to provide water for human consumption, irrigating lands, generating hydroelectric power, and use in industrial processes. They are critical structures for continuing life and providing public safety. Construction of a dam is a complicated task that requires sophisticated modern technology and technical expertise. Scientists need to review and adjust their perspectives on designing embankments and their related structures, and compaction and consolidation of fill material, behavior of concrete materials, geotechnical and seismological studies of the dam site, total risk analysis, safety monitoring and instrumentation, heightening, hydrological studies, soil conservation, and watershed management. This book intends to provide the reader with a comprehensive overview of the latest information in dam engineering.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Stratification, i.e., density variations in a reservoir, occurs due to temperature variations as a result of surface heat exchange and plays an important role in determining the water quality of a reservoir. This role is determined through the influence of density variations on the movement of water in the reservoir. Therefore, the primary objective of a prediction of stratified flow hydrodynamics in reservoirs is to enable scientists to compute temperature distributions and water transports insofar as they affect various water quality parameters. One objective of the Environmental & Water Quality Operational Study (EWQOS) program of the U.S. Army Corps of Engineers is to provide District and Division offices with a tool for predicting reservoir hydrodynamics over periods of time extending from the initial setup of thermal stratification in the spring through its breakup in the fall. Such a predictive technique will subsequently be used in the prediction of water quality parameters. Both two- and three-dimensional, unsteady, variable density, heat-conducting models have been investigated during the past year. This investigation has centered around an analysis of both the mathematical and numerical bases of individual models as well as their ability to simulate a density underflow.

Book excerpt: Computational fluid dynamics (CFD) is one discipline falling under the broad heading of computer-aided engineering (CAE). CAE, together with computer-aided design (CAD) and computer-aided manufacturing (CAM), comprise a mathematical-based approach to engineering product and process design, analysis and fabrication. In this overview of CFD for the design engineer, our purposes are three-fold: (1) to define the scope of CFD and motivate its utility for engineering, (2) to provide a basic technical foundation for CFD, and (3) to convey how CFD is incorporated into engineering product and process design.

Al-Zubaidi and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hydrodynamic numerical modeling is increasingly becoming a widely used tool for simulating the surface waterbodies including rivers, lakes, and reservoirs. A challenging step in any model development is the verification tests, especially at the early stage of development. In this study, a unique approach was developed by implementing the volume balance principle in order to verify the three-dimensional hydrodynamic models for surface waterbody simulation. A developed and verified three-dimensional hydrodynamic and water quality model, called W3, was employed by setting a case study model to be verified using the volume balance technique. The model was qualified by calculating the error in the accumulated water volume within the domain every time step. Results showed that the volume balance reached a constant error over the simulation period, indicating a robust model setup.

Available in PDF, EPUB and Kindle. Book excerpt: Numerical modeling has become a major tool for managing water quality in surface waterbodies such as rivers, lakes, reservoirs, and estuaries. Since the two-dimensional longitudinal/vertical model CE-QUAL-W2 is a well-known model and it has been applied to thousands of waterbodies around the world successfully, its numerical scheme was adapted to develop a new three-dimensional numerical model for simulating hydrodynamics, temperature, and water quality in surface waterbodies.
