Infolge des technischen Fortschritts werden Bauelemente und Systeme haufig auch in ihrer Groesse verandert. Aufgrund der Massstabsanderung weisen sie meistens ein geandertes physikalisches Verhalten und damit auch andere Eigenschaften auf.Das in diesem Buch beschriebene Verfahren der Skalierung ermoeglicht ohne grossen zeitlichen und finanziellen Aufwand das Verhalten und die Eigenschaften dieser in ihrer Groesse veranderten Bauelemente und Systeme zu bestimmen bzw. vorherzusagen. Der Leser wird uber zahlreiche Beispiele und Anwendungen verstandlich in die Skalierung der physikalischen Gesetze und der mathematischen Modellierung eingefuhrt. Es gibt wohl derzeit kein vergleichbares Werk, welches die Skalierung uber die physikalischen Gebiete der Mechanik, der Schwingungen und Wellen, der Fluidik, der Thermodynamik und des Elektromagnetismus in dieser Ausfuhrlichkeit darstellt. Erstmals wird auch der Einfluss der mathematischen Methoden auf die Skalierung umfassend behandelt. Das Buch richtet sich an Studierende der Ingenieurwissenschaften und der Physik. Es ist aber auch unentbehrlich fur jeden, der sich mit der Entwicklung von neuen innovativen Produkten und Systemen im Bereich der Miniaturisierung beschaftigt.

This exciting new textbook introduces the concepts and tools essential for upper-level undergraduate study in water resources and hydraulics. Tailored specifically to fit the length of a typical one-semester course, it will prove a valuable resource to students in civil engineering, water resources engineering, and environmental engineering. It will also serve as a reference textbook for researchers, practicing water engineers, consultants, and managers. The book facilitates students' understanding of both hydrologic analysis and hydraulic design. Example problems are carefully selected and solved clearly in a step-by-step manner, allowing students to follow along and gain mastery of relevant principles and concepts. These examples are comparable in terms of difficulty level and content with the end-of-chapter student exercises, so students will become well equipped to handle relevant problems on their own. Physical phenomena are visualized in engaging photos, annotated equations, graphical illustrations, flowcharts, videos, and tables.

In Chapter One, Fujun Wang, Chaoyue Wang, Zhengjun Yang, Peijian Zhou, and Zhifeng Yao propose and examine a dynamic mixed nonlinear SGS model, with the results indicating that this wall-resolved near-wall solution could capture details more accurately. In Chapter Two, Jose Gonzalez and Jesus M. Fernandez present a study wherein the flow in a one stage, single volute centrifugal pump is examined at the Fluid Mechanics Laboratory at the Universidad de Oviedo. In Chapter Three, Hua-Shu Dou, Lulu Zheng, Zuchao Zhu, Xiaoping Chen, and Baoling Cui discuss the evolution of the separating flow and pressure variation distribution around the tongue region in a centrifugal pump. In Chapter Four, Angelo Leto discusses centrifugal pumps for liquid-propellant engines for space propulsion applications. Jamshid H. Karimov, MD, PhD, Shinji Okano, MD, and Kiyotaka Fukamachi, MD, PhD review continuous-flow mechanical circulatory support technology in Chapter Five. Next, Susanta K. Das wraps up the book with an experiment on the effect of impeller vane geometry design on the performance of a centrifugal pump.

This book examines national levee safety with a focus on recommendations and strategic plan implementations of the National Committee on Levee Safety. It is a critical juncture in our nations' history with a burgeoning growth of risk to people and infrastructure as a result of more than 100 years of inattention to levee infrastructure combined with an economy and social fabric that are in a particularly vulnerable state. The current levee safety reality for the United States is stark and uncertain in location, performance and condition of levees and a lack of oversight, technical standards, and effective communication of risks. A look to the future offers two distinct possibilities: one where we continue the status quo and await the certainty of more catastrophes or one where we take reasonable actions and investments in a National Levee Safety Program that turns the tide on risk growth.

This two-volume book is a comprehensive guide to designing, conducting and interpreting experiments in a broad range of topics associated with hydraulic engineering. It is the first substantial effort in hydraulic engineering to assemble in one place descriptions of all the components of experimentation along with a concise outline of essential theory to highlight the intrinsic connection between analytical and experimental research and illustrate the need for their complementary use. Providing end-to-end guidance to support experimentalists is long overdue, as most of the information can only be found in scientific papers or specialized monographs on laboratory and fieldwork practice. The book was prepared for college faculty, researchers, practitioners, and students involved in hydraulics experiments. Written by a team of more than 45 authors well-experienced in hydraulics experimentation, the book takes into account experiments performed under a range of conditions, including well-equipped and -staffed laboratories, and laboratories lacking aspects of advanced instrumentation and expertise. The book could serve as a textbook on hydraulics experiments. Its style is intentionally concise and makes frequent use of convenient summaries, tables and figures to present information. The writers provide specific guidance on methods and instruments currently used in hydraulics experiments, and emphasizes new and emerging measurement technologies and analysis methods. Extensive references enable interested readers to further explore details on each topic. Although the book focuses primarily on laboratory experiments, including hydraulic modelling, it also applies to fieldwork of varying complexity and accessibility.
