    Book SynopsisCovering classical aerodynamic theories and applications made possible by computational aerodynamics, this book provides a discussion on lift and drag from an overall dynamical approach, and after stating the governing Navier-Stokes equation, covers potential flows and panel method.Trade Review“The book ‘is aimed to be a comprehensive textbook’: the classical subject matter, including the transition and stability theory in Chapter 9, would be a useful addition to the literature of any undergraduate or graduate student; the computational sections contain little in terms of fundamentals of numerics but, accepting that useful computational results are the focus, results are presented for several applications that would be of interest to many aerodynamicists.” (The

    Book SynopsisThe why, what and how of the electric vehicle powertrain Empowers engineering professionals and students with the knowledge and skills required to engineer electric vehicle powertrain architectures, energy storage systems, power electronics converters and electric drives. The modern electric powertrain is relatively new for the automotive industry, and engineers are challenged with designing affordable, efficient and high-performance electric powertrains as the industry undergoes a technological evolution. Co-authored by two electric vehicle (EV) engineers with decades of experience designing and putting into production all of the powertrain technologies presented, this book provides readers with the hands-on knowledge, skills and expertise they need to rise to that challenge. This four-part practical guide provides a comprehensive review of battery, hybrid and fuel cell EV systems and the associated energy sources, power electronics, machines, and drives. Introduces and holisTrade ReviewHayes and Goodarzi have focused their considerable talent and experience to teaching the inner workings of the electric car. Readers, whether engineers, students, or the interested public will find this book a treasure trove of knowledge on modern automotive technology. In conclusion, what a great book! —John M Miller, J-N-J Miller Design Services PLLC, Longview, Texas, USA I highly recommend 'Electric Powertrain: Energy Systems, Power Electronics and Drives for Hybrid, Electric and Fuel Cell Vehicles' by Dr John G. Hayes and Dr G. Abas Goodarzi. I use this book as my core teaching text on my module Transportation Power and Systems 3, which I teach to third year BEng and MEng Mechanical Engineering undergraduates in Queen's University Belfast. This book captures the fundamentals and in-depth aspects of the key elements of the course I teach including drive cycles, power trains for hybrids, vehicle dynamics, batteries and machines. The worked examples are excellent. The text book is very well laid out with superb well thought-out practical problems at the end of each chapter. This book is very relevant to those who wish to expand their knowledge of hybrid vehicles. It seamlessly integrates the electrical, civil and mechanical disciplines in this growing and multidisciplinary area. This is especially important considering the sustainable direction of land-based transport will take over the next decade as we strive to combat global warming and reduce greenhouse gas emissions. —Dr

    Book SynopsisThis student version of the popular bestseller, Life Cycle Assessment Handbook, is not a watered-down version of the original, but retains all of the important information and valuable lessons provided in the first book, along with helpful problems and solutions for the student learning about Life Cycle Assessment (LCA). As the last several decades have seen a dramatic rise in the application of LCA in decision making, the interest in the life cycle concept as an environmental management and sustainability tool continues to grow. The LCA Student Handbook offers a look at the role that life cycle information, in the hands of companies, governments and consumers, may have in improving the environmental performance of products and technologies. It concisely and clearly presents the various aspects of LCA in order to help the reader better understand the subject. The international success of the sustainability paradigm needs the participation of many stakeholders, including citizens,Table of ContentsPreface ix 1 Introduction to Life Cycle Assessment 1

    Book SynopsisElectromagnetism for Engineers An easily accessible textbook to introduce the power of electromagnetism Electromagnetism can be a difficult subject to grasp and to teach. Much of what we take for granted in modern life is enabled by electromagnetic effects, but it isn't always easy to understand the impact of electromagnetism compared to other areas of engineering, such as mechanics, which are more tangibly observed and felt. Although electromagnetism is a crucial and important branch of physics with elegant mathematics, many students can find the study of electromagnetism inaccessible. It is crucial for students of electrical and electronic engineering and physics to have a strong understanding of electromagnetism and how it impacts communications, power generation and transmission, semiconductor devices, motors, and more. Electromagnetism for Engineers aims to develop a student's understanding of electromagnetism in the context of real effects and how they apply to such applicationsTable of ContentsPreface ix Acknowledgements xi About the Author xii Symbols xiii About the Companion Website xv Part I Fundamentals of Electricity and Magnetism 1 1 Charge and Electric Fields 3 2 Electric Fields in Materials 15 3 Currents and Magnetic Fields 37 4 Magnetic Fields in Materials 51 5 The Maxwell Equations of Elecromagnetism 71 Part II Applications of Electromagnetism 83 6 Transmission Lines 85 7 Electromagnetic Waves in Dielectric Media 115 8 Antennas 131 9 Electromagnetic Waves at Dielectric Interfaces 143 10 Electromagnetic Waves in Conducting Media 161 11 Waveguides 173 12 Three-Phase Electrical Power 187 Epilogue 203 Index 205

    Book SynopsisAn essential guide to modern circuit board design based on simple physics and practical applications The fundamentals taught in circuit theory were never intended to work above a few megahertz, let alone at a gigahertz. While electronics is grounded in physics, most engineers' education in this area is too general and mathematical to be easily applied to the problem of high speed circuits. Left to their own devices, many engineers produce layouts that require expensive revisions in order to finally meet specifications.

  • Wind Energy Handbook

    John Wiley & Sons Inc Wind Energy Handbook

    1 in stock

    Book SynopsisFully updated and authoritative reference to wind energy technology written by leading academic and industry professionals The newly revised Third Edition of the Wind Energy Handbook delivers a fully updated treatment of key developments in wind technology since the publication of the book's Second Edition in 2011. The criticality of wakes within wind farms is addressed by the addition of an entirely new chapter on wake effects, including 'engineering' wake models and wake control. Offshore, attention is focused for the first time on the design of floating support structures, and the new 'PISA' method for monopile geotechnical design is introduced. The coverage of blade design has been completely rewritten, with an expanded description of laminate fatigue properties and new sections on manufacturing methods, blade testing, leading-edge erosion and bend-twist coupling. These are complemented by new sections on blade add-ons and noise in the aerodynamics chapters, which now also include a description of the Leishman-Beddoes dynamic stall model and an extended introduction to Computational Fluid Dynamics analysis. The importance of the environmental impact of wind farms both on- and offshore is recognized by expanded coverage, and the requirements of the Grid Codes to ensure wind energy plays its full role in the power system are described. The conceptual design chapter has been extended to include a number of novel concepts, including low induction rotors, multiple rotor structures, superconducting generators and magnetic gearboxes. References and further reading resources are included throughout the book and have been updated to cover the latest literature. As in previous editions, the core subjects constituting the essential background to wind turbine and wind farm design are covered. These include: The nature of the wind resource, including geographical variation, synoptic and diurnal variations, and turbulence characteristicsThe aerodynamics of horizontal axis wind turbines, including the actuator disc concept, rotor disc theory, the vortex cylinder model of the actuator disc and the Blade-Element/Momentum theoryDesign loads for horizontal axis wind turbines, including the prescriptions of international standardsAlternative machine architecturesThe design of key componentsWind turbine controller design for fixed and variable speed machinesThe integration of wind farms into the electrical power systemWind farm design, siting constraints, and the assessment of environmental impact Perfect for engineers and scientists learning about wind turbine technology, the Wind Energy Handbook will also earn a place in the libraries of graduate students taking courses on wind turbines and wind energy, as well as industry professionals whose work requires a deep understanding of wind energy technology.Table of ContentsAbout the Authors xxi Preface to Second Edition xxiii Preface to Third Edition xxv Acknowledgements for the First Edition xxix Acknowledgements

    Book SynopsisDiscover a comprehensive exploration of recent developments and fundamental concepts in the applications of metasurfaces. In Electromagnetic Metasurfaces: Theory and Applications, distinguished researchers and authors Karim Achouri and Christophe Caloz deliver an introduction to the fundamentals and applications of metasurfaces and an insightful analysis of recent and future developments in the field. The book describes the precursors and history of metasurfaces before continuing on to an exploration of the physical insights that can be gleaned from the material parameters of the metasurface. You'll learn how to compute the fields scattered by a metasurface with known material parameters being illuminated by an arbitrary incident field, as well as how to realize a practical metasurface and relate its material parameters to its physical structures. The authors provide examples to illustrate all the concepts discussed in the book to improve and simplify reaTable of ContentsPreface ix 1 Introduction 1 1.1 Metamaterials 1 1.2 Emergence of Metasurfaces 4 2 Electromagnetic Properties of Materials 9 2.1 Bianisotropic Constitutive Relations 10 2.2 Temporal Dispersion 14 2.2.1 Causality and Kramers-Kronig Relations 15 2.2.2 Lorentz Oscillator Model 17 2.3 Spatial Dispersion 23 2.4 Lorentz Reciprocity Theorem 27 2.5 Poynting Theorem 32 2.6 Energy Conservation in Lossless-Gainless Systems 38 2.7 Classi_cation of Bianisotropic Media 41 3 Metasurface Modeling 43 3.1 E_ective Homogeneity 44 3.1.1 The Homogeneity Paradox 44 3.1.2 Theory of Periodic Structures 44 3.1.3 Scattering from Gratings 46 3.1.4 Homogenization 47 3.2 E_ective Zero Thickness 50 3.3 Sheet Boundary Conditions 53 3.3.1 Impedance Modeling 54 3.3.2 Polarizability Modeling 57 3.3.3 Susceptibility Modeling 60 3.3.4 Comparisons between the Models 66 4 Susceptibility Synthesis 69 4.1 Linear Time-Invariant Metasurfaces 69 4.1.1 Basic Assumptions 69 4.1.2 Birefringent Metasurfaces 76 4.1.3 Multiple-Transformation Metasurfaces 78 4.1.4 Relations between Susceptibilities and Scattering Parameters 81 4.1.5 Surface-Wave Eigenvalue Problem 92 4.1.5.1 Formulation of the Problem 92 4.1.5.2 Dispersion in a Symmetric Environments 96 4.1.6 Metasurfaces with Normal Polarizations 100 4.1.7 Illustrative Examples 104 4.1.7.1 Polarization Rotation 104 4.1.7.2 Multiple Nonreciprocal Transformations 109 4.1.7.3 Angle-Dependent Transformations 112 4.2 Time-Varying Metasurfaces 117 4.2.1 Formulation of the Problem 117 4.2.2 Harmonic-Generation Time-Varying Metasurface 120 4.3 Nonlinear Metasurfaces 121 4.3.1 Second-Order Nonlinearity 122 4.3.1.1 Frequency-Domain Approach 123 4.3.1.2 Time-Domain Approach 128 5 Scattered Field Computation 133 5.1 Fourier-Based Propagation Method 134 5.2 Finite-Di_erence Frequency-Domain Method 141 5.3 Finite-Di_erence Time-Domain Method 147 5.3.1 Time-Varying Dispersionless Metasurfaces 150 5.3.2 Time-Varying Dispersive Metasurfaces 156 5.4 Spectral-Domain Integral Equation Method 164 6 Practical Implementation 173 6.1 General Implementation Procedure 174 6.2 Basic Strategies for Full-Phase Coverage 178 6.2.1 Linear Polarization 179 6.2.1.1 Metallic Scattering Particles 179 6.2.1.2 Dielectric Scattering Particles 188 6.2.2 Circular Polarization 194 6.3 Full-Phase Coverage with Perfect Matching 198 6.4 Effects of Symmetry Breaking 207 6.4.1 Angular Scattering 208 6.4.2 Polarization Conversion 215 7 Applications 223 7.1 Angle-Independent Transformation 224 7.2 Perfect Matching 229 7.3 Generalized Refraction 234 7.3.1 Limitations of Conventional Synthesis Methods 234 7.3.2 Perfect Refraction using Bianisotropy 239 8 Conclusions 245 9 Appendix 249 9.1 Approximation of Average Fields at an Interface 249 9.2 Fields Radiated by a Sheet of Dipole Moments 252 9.3 Relations between Susceptibilities and Polarizabilities 255 Bibliography 260

    Book SynopsisPARTIAL DISCHARGES (PD) DETECTION, IDENTIFICATION AND LOCALIZATION Explore state-of-the-art partial discharge measurement techniques In Partial Discharges (PD) Detection, Identification and Localization, a team of distinguished electrical engineers delivers a comprehensive treatment of the behavior, modeling, measurement, monitoring, localization, and evaluation of partial discharges. It includes coverage of all major advancements in the field that have occurred over the last few decades. It also discusses partial discharge phenomena, detection methods, and strategies for analyzing and processing collected data. Mechanisms of insulation failure are explored, as is the denoising of partial discharge measurement data and the localization of partial discharge in large, high-voltage equipment. Non-electric principles and procedures are discussed, and the book offers a variety of tables, figures, and photographs to illustrate the concepts discussed within.
