This book was released on 2010-03-10 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Open channel hydraulics has always been a very interesting domain of scienti c and engineering activity because of the great importance of water for human l- ing. The free surface ow, which takes place in the oceans, seas and rivers, can be still regarded as one of the most complex physical processes in the environment. The rst source of dif culties is the proper recognition of physical ow processes and their mathematical description. The second one is related to the solution of the derived equations. The equations arising in hydrodynamics are rather comp- cated and, except some much idealized cases, their solution requires application of the numerical methods. For this reason the great progress in open channel ow modeling that took place during last 40 years paralleled the progress in computer technique, informatics and numerical methods. It is well known that even ty- cal hydraulic engineering problems need applications of computer codes. Thus, we witness a rapid development of ready-made packages, which are widely d- seminated and offered for engineers. However, it seems necessary for their users to be familiar with some fundamentals of numerical methods and computational techniques applied for solving the problems of interest. This is helpful for many r- sons. The ready-made packages can be effectively and safely applied on condition that the users know their possibilities and limitations. For instance, such knowledge is indispensable to distinguish in the obtained solutions the effects coming from the considered physical processes and those caused by numerical artifacts.

This book was released on 2010-09-14 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: This scholarly text provides an introduction to the numerical methods used to model partial differential equations, with focus on atmospheric and oceanic flows. The book covers both the essentials of building a numerical model and the more sophisticated techniques that are now available. Finite difference methods, spectral methods, finite element method, flux-corrected methods and TVC schemes are all discussed. Throughout, the author keeps to a middle ground between the theorem-proof formalism of a mathematical text and the highly empirical approach found in some engineering publications. The book establishes a concrete link between theory and practice using an extensive range of test problems to illustrate the theoretically derived properties of various methods. From the reviews: "...the books unquestionable advantage is the clarity and simplicity in presenting virtually all basic ideas and methods of numerical analysis currently actively used in geophysical fluid dynamics."

Mechanics of environmental fluids is concerned with fluid motion, associated mass and heat transport as well as deformation processes in subsurface systems. In this reference work the fundamental modelling approaches based on continuum mechanics for fluids in the environment are described, including porous media and turbulence. Numerical methods for solving the process governing equations as well as its object-oriented computer implementation are discussed and illustrated with examples. Finally, the application of computer models in civil and environmental engineering is demonstrated.

Download or read book Computational Modeling for Fluid Flow and Interfacial Transport written by W. Shyy and published by Elsevier. This book was released on 2013-10-22 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transport processes are often characterized by the simultaneous presence of multiple dependent variables, multiple length scales, body forces, free boundaries and strong non-linearities. The various computational elements important for the prediction of complex fluid flows and interfacial transport are presented in this volume. Practical applications, presented in the form of illustrations and examples are emphasized, as well as physical interpretation of the computed results. The book is intended as a reference for researchers and graduate students in mechanical, aerospace, chemical and materials engineering. Both macroscopic and microscopic (but still continuum) features are addressed. In order to lay down a good foundation to facilitate discussion of more advanced techniques, the book has been divided into three parts. Part I presents the basic concepts of finite difference schemes for solving parabolic, elliptic and hyperbolic partial differential equations. Part II deals with issues related to computational modeling for fluid flow and transport phenomena. Existing algorithms to solve the Navier-Stokes equations can be generally classified as density-based methods and pressure-based methods. In this book the pressure-based method is emphasized. Recent efforts to improve the performance of the pressure-based algorithm, both qualitatively and quantitatively, are treated, including formulation of the algorithm and its generalization to all flow speeds, choice of coordinate system and primary velocity variables, issues of grid layout, open boundary treatment and the role of global mass conservation, convection treatment and convergence. Practical engineering applications, including gas-turbine combustor flow, heat transfer and convection in high pressure discharge lamps, thermal management under microgravity, and flow through hydraulic turbines are also discussed. Part III addresses the transport processes involving interfacial dynamics. Specifically those influenced by phase change, gravity, and capillarity are emphasized, and both the macroscopic and morphological (microscopic) scales are presented. Basic concepts of interface, capillarity, and phase change processes are summarized to help clarify physical mechanisms, followed by a discussion of recent developments in computational modeling. Numerical solutions are also discussed to illustrate the salient features of practical engineering applications. Fundamental features of interfacial dynamics have also been illustrated in the form of case studies, to demonstrate the interplay between fluid and thermal transport of macroscopic scales and their interaction with interfacial transport.

This book was released on 2013-03-14 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first Symposium on Recent Advances in Problems of Flow and Transport in Porous Media was held in Marrakech in June '96 and has provided a focus for the utilization of computer methods for solving the many complex problems encountered in the field of solute transport in porous media. This symposium has been successful in bringing together scientists, physicists, hydrogeologists, researchers in soil and fluid mechanics and engineers involved in this multidisciplinary subject. It is clear that the utilization of computer-based models in this domain is still rapidly expanding and that new and novel solutions are being developed. The contributed papers which form this book reflect the recent advances, in particular with respect to new methods, inverse problems, reactive transport, unsaturated media and upscaling. These have been subdivided into the following sections: I. Numerical methods II. Mass transport and heat transfer III. Comparison with experimentation and simulation of real cases This book contains reviewed articles of the top presentations held during the International Symposium on Computer Methods in Porous Media Engineering which took place in Giens (France) in October 1998. All of the presentations and the optimism shown during the meeting provided further evidence that computer modeling is making remarkable progress and is indeed becoming an essential toolkit in the field of porous media and solute transport. I believe that the content of this book provides evidence of this and furthermore gives a comprehensive review of the theoretical developments and applications.

Available in PDF, EPUB and Kindle. Book excerpt: Modelling forms a vital part of all engineering design, yet many hydraulic engineers are not fully aware of the assumptions they make. These assumptions can have important consequences when choosing the best model to inform design decisions. Considering the advantages and limitations of both physical and mathematical methods, this book will help you identify the most appropriate form of analysis for the hydraulic engineering application in question. All models require the knowledge of their background, good data and careful interpretation and so this book also provides guidance on the range of accuracy to be expected of the model simulations and how they should be related to the prototype. Applications to models include: open channel systems closed conduit flows storm drainage systems estuaries coastal and nearshore structures hydraulic structures. This an invaluable guide for students and professionals.
