Book Description
This book reponds to the increasing demand of computer mo- delling of electrochemical processes in order to improve their speed and efficiency. The fundamental transport equa- tions in dilute solutions are given and it is established in detail under what circumstances a potential model with non- linear boundary conditions, involved by electrode reactions, can beused. Attention is directed towards the most impor- tant solution techniquesFEM, FDM and BEM and towards the solution of the non-linear system of equations (Successive Substitution, Newton-Raphson). Using the BEM, several two- dimensional and axisymmetrical examples of current density distributions are given and quantitative data, obtained in a copper electro-refining cell, are compared with calculated results. Applying Faraday's Law and the BEM, simulation of electro-deposition, electro-chemical levelling and machining are treated. Accuracy and stabilityare emphasized.

Book Description
The boundary element method (BEM) is a modern numerical techniquewhich has enjoyed increasing popularity over the last two decades,and is now an established alternative to traditional computationalmethods of engineering analysis. The main advantage of the BEM isits unique ability to provide a complete solution in terms ofboundary values only, with substantial savings in modelling effort. This two-volume book set is designed to provide the readers with acomprehensive and up-to-date account of the boundary element methodand its application to solving engineering problems. Each volume isa self-contained book including a substantial amount of materialnot previously covered by other text books on the subject. Volume 1covers applications to heat transfer, acoustics, electrochemistryand fluid mechanics problems, while volume 2 concentrates on solidsand structures, describing applications to elasticity, plasticity,elastodynamics, fracture mechanics and contact analysis. The earlychapters are designed as a teaching text for final yearundergraduate courses. Both volumes reflect the experience of theauthors over a period of more than twenty years of boundary element research. This volume, Applications in Thermo-Fluids and Acoustics, provides acomprehensive presentation of the BEM from fundamentals to advancedengineering applications and encompasses: Steady and transient heat transfer Potential and viscous fluid flows Frequency and time-domain acoustics Corrosion and other electrochemical problems. A unique feature of this book is an in-depth presentation of BEMformulations in all the above fields, including detaileddiscussions of the basic theory, numerical algorithms and practicalengineering applications of the method. Written by an internationally recognised authority in the field,this is essential reading for postgraduates, researchers andpractitioners in civil, mechanical and chemical engineering andapplied mathematics.

Book Description
Selected from papers presented at the 8th Scientific Computation in Electrical Engineering conference in Toulouse in 2010, the contributions to this volume cover every angle of numerically modelling electronic and electrical systems, including computational electromagnetics, circuit theory and simulation and device modelling. On computational electromagnetics, the chapters examine cutting-edge material ranging from low-frequency electrical machine modelling problems to issues in high-frequency scattering. Regarding circuit theory and simulation, the book details the most advanced techniques for modelling networks with many thousands of components. Modelling devices at microscopic levels is covered by a number of fundamental mathematical physics papers, while numerous papers on model order reduction help engineers and systems designers to bring their modelling of industrial-scale systems within the reach of present-day computational power. Complementing these more specific papers, the volume also contains a selection of mathematical methods which can be used in any application domain.

Book Description
Metal-air is a promising battery system that uses inexpensive metals for its negative electrode while unlimited, free and non-toxic oxygen is used for its positive electrode, however, only primary systems have been commercialized so far. Electrochemical Power Sources: Fundamentals, Systems, and Applications – Metal–Air Batteries: Present and Perspectives offers a comprehensive understanding of metal-air batteries as well as the solutions to the issues for overcoming the related difficulties of the secondary (rechargeable) system. Although metal-air batteries are widely studied as low-cost high-energy systems, their commercialization is limited to primary ones due to currently limited cycle life and insufficient reliability. For realization of the secondary systems, this book offers comprehensive understanding of metal-air batteries, including the details of both electrodes, electrolyte, cell/system, modelling and applications. Electrochemical Power Sources: Fundamentals, Systems, and Applications – Metal–Air Batteries: Present and Perspectives provides researchers, instructors, and students in electrochemistry, material science and environmental science; industry workers in cell manufacturing; and government officials in energy, environmental, power supply, and transportation with a valuable resource covering the most important topics of metal-air batteries and their uses. - Outlines the general characteristics of metal-air compared with conventional batteries - Offers a comprehensive understanding of various metal-air, featuring zinc, and lithium - Contains comparisons and issues among various metal-air batteries and research efforts to solve them - Includes applications and market prospects

Book Description
The application of BEM in all fields of engineering and science has progressed at an accelerate rate since the first book on the method appeared in the late seventies. In particular the advantages of BEM for potential problems are essential to solve a whole range of electrical engineering problems. Previous volumes in this series have focussed on the state of the art in other fields while this volume discusses only problems related to electrical engineering. The book reviews a series of important applications such as the design of semiconductor devices and their thermal analysis. The following two chapters concentrate on the study of galvanic corrosion and cathodic protection. Chapter 4 deals with the design of capacitance transducers. The next three chapters concentrate on the applications of the method to simulate electrochemical problems with special reference to Plating Process. The last chapter in the book discusses the case of inverse problems in electrical engineering and presents some applications including their use in tomography.
