Book Description
This book will provide the necessary theoretical background and a description of plasma-related devices and processes that are used industrially for physicists and engineers. It is a self-contained introduction to the principles of plasma engineering with comprehensive references. This volume also includes the terminology, jargon and acronyms used in the field of industrial plasma engineering - indexed when they first appear in the text - along with their definitions and a discussion of their meaning. It is aimed at assisting the student in learning key terminology and concepts, and providing the in-service engineer or scientist with a technical glossary. An extensive index and appendices enhance the value of this book as a key reference source. These incorporate a list of the nomenclature used in mathematical expressions in the text, physical constants, and often-used plasma formulae. SI units are used throughout. Intended for students from all engineering and physical science disciplines, and as a reference source by in-service engineers. Coverage: * basic information on plasma physics and the physical processes important in industrial plasmas * sources of ion and electron beams and ionizing radiation used in industrial applications * physics and technology of DC and RF electrical discharges.

Book Description
For the efficient utilization of energy resources and the minimization of environmental damage, thermoelectric materials can play an important role by converting waste heat into electricity directly. Nanostructured thermoelectric materials have received much attention recently due to the potential for enhanced properties associated with size effects and quantum confinement. Nanoscale Thermoelectrics describes the theory underlying these phenomena, as well as various thermoelectric materials and nanostructures such as carbon nanotubes, SiGe nanowires, and graphene nanoribbons. Chapters written by leading scientists throughout the world are intended to create a fundamental bridge between thermoelectrics and nanotechnology, and to stimulate readers' interest in developing new types of thermoelectric materials and devices for power generation and other applications. Nanoscale Thermoelectrics is both a comprehensive introduction to the field and a guide to further research, and can be recommended for Physics, Electrical Engineering, and Materials Science departments.

Book Description
The book describes the results of investigations of the electrophysical, chemical, gas-dynamic and other processes in low-temperature plasma, their diagnostics, modelling and application in various areas of science and technology. Special attention is given to the problems associated with physico-chemical processes and chemical reactions in nonequilibrium and (quasi) equilibrium low-temperature plasma. Kinetic and thermodynamic aspects of plasmochemical reactions and their mechanisms, determined mainly by reactions under electron impacts and reactions of vibrationally excited molecules, are discussed.

Book Description
Describes the rotordynamic considerations that are important to the successful design or troubleshooting of a turbomachine. Shows how bearing design, fluid seals, and rotor geometry affect rotordynamic behavior (vibration, shaft whirling, bearing loads, and critical speeds), and describes two successful computational methods for rotordynamic analysis in terms that can be understood by practicing engineers. Gives descriptive accounts of the state of the art in several areas of the field and presents important mathematical or computational concepts, describing equations and formulas in physical terms for better understanding. Also offers tips for troubleshooting unstable machines and provides practical interpretations of vibration measurements.

Book Description
This book provides an introduction to the theory of turbulence in fluids based on the representation of the flow by means of its vorticity field. It has long been understood that, at least in the case of incompressible flow, the vorticity representation is natural and physically transparent, yet the development of a theory of turbulence in this representation has been slow. The pioneering work of Onsager and of Joyce and Montgomery on the statistical mechanics of two-dimensional vortex systems has only recently been put on a firm mathematical footing, and the three-dimensional theory remains in parts speculative and even controversial. The first three chapters of the book contain a reasonably standard intro duction to homogeneous turbulence (the simplest case); a quick review of fluid mechanics is followed by a summary of the appropriate Fourier theory (more detailed than is customary in fluid mechanics) and by a summary of Kolmogorov's theory of the inertial range, slanted so as to dovetail with later vortex-based arguments. The possibility that the inertial spectrum is an equilibrium spectrum is raised.

Book Description
Computational aeroacoustics (CAA) is a relatively new research area. CAA algorithms have developed rapidly and the methods have been applied in many areas of aeroacoustics. The objective of CAA is not simply to develop computational methods but also to use these methods to solve practical aeroacoustics problems and to perform numerical simulation of aeroacoustic phenomena. By analysing the simulation data, an investigator can determine noise generation mechanisms and sound propagation processes. This is both a textbook for graduate students and a reference for researchers in CAA and as such is self-contained. No prior knowledge of numerical methods for solving partial differential equations (PDEs) is needed, however, a general understanding of partial differential equations and basic numerical analysis is assumed. Exercises are included and are designed to be an integral part of the chapter content. In addition, sample computer programs are included to illustrate the implementation of the numerical algorithms.
