Download or read book Air Entrainment Relationship with Water Discharge of Vortex Drop Structures written by Cody N. Pump and published by . This book was released on 2011 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vortex drop shafts are used to transport water or wastewater from over-stressed existing sewer systems to underground tunnels. During the plunge a large amount of air is entrained into the water and released downstream of the drop shaft into the tunnel. This air is unwanted and becomes costly to treat and move back to the surface. Determining the amount of air that will be entrained is a difficult task. A common method is to build a scale model and measure the air discharge and scale it back to prototype. This study investigated a possible relationship between the geometry of the drop structure, the water discharge and the amount of air entrained. The results have shown that air entrainment is still not entirely understood, however we are close to a solution. Using a relationship of the air core diameter, drop shaft length and terminal velocity of the water, a likely exponential relationship has been developed.

Download or read book Hydraulic and Civil Engineering Technology VII written by M. Yang and published by IOS Press. This book was released on 2022-12-23 with total page 1428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering technology is of crucial importance to the infrastructure on which modern societies depend, and keeping abreast of the latest research and developments in the field is of vital importance. This book presents the proceedings of HCET 2022, the 7th International Technical Conference on Frontiers of Hydraulic and Civil Engineering Technology, originally due to be held, in Sanya, China, from 25-27 September 2022, but instead held as a fully virtual event on Zoom due to continued uncertainty related to the Covid 19 pandemic. HCET is a platform for the dissemination of research results on the latest advances in the areas of hydraulic and civil engineering technology and environmental engineering, and provides an opportunity for scientists, researchers and engineers from around the world to exchange their findings, discuss developments, and possibly establish a basis for collaboration. A total of 275 submissions were received from international contributors, and all were subjected to a rigorous peer-review process, with each paper reviewed by a minimum of two experts. Papers were also checked for quality and plagiarism, after which, 163 papers were accepted for presentation and publication. Topics covered include the research and development of concrete structure design and analysis, structural mechanics and structural engineering, geological exploration and earthquake engineering, building technology, urban planning, energy, environment and advanced engineering science and applications. The book offers a state-of-the-art overview of recent developments, and will be of interest to all those working in the fields of hydraulic and civil engineering technology.

Download or read book Wastewater Hydraulics written by Willi H. Hager and published by Springer Science & Business Media. This book was released on 2010-11-25 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second, enlarged edition of this established reference integrates many new insights into wastewater hydraulics. This work serves as a reference for researchers but also is a basis for practicing engineers. It can be used as a text book for graduate students, although it has the characteristics of a reference book. It addresses mainly the sewer hydraulician but also general hydraulic engineers who have to tackle many a problem in daily life, and who will not always find an appropriate solution. Each chapter is introduced with a summary to outline the contents. To illustrate application of the theory, examples are presented to explain the computational procedures. Further, to relate present knowledge to the history of hydraulics, some key dates on noteworthy hydraulicians are quoted. A historical note on the development of wastewater hydraulics is also added. References are given at the end of each chapter, and they are often helpful starting points for further reading. Each notation is defined when introduced, and listed alphabetically at the end of each chapter. This new edition includes in particular sideweirs with throttling pipes, drop shafts with an account on the two-phase flow features, as well as conduit choking due to direct or undular hydraulic jumps.

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.

Download or read book Free Surface Hydraulics written by Dr J M Townson and published by CRC Press. This book was released on 2014-04-21 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
