Book excerpt: EDDY CURRENTS Understand the theory of eddy currents with this essential reference Eddy currents are electrical current loops produced when a conductor passes through a magnetic field, or is otherwise subject to a change in magnetic field direction. These currents play a significant role in many industrial processes and areas of electrical engineering. Their properties and applications are therefore a subject of significant interest for electrical engineers and other professionals. Eddy Currents: Theory, Modeling and Applications offers a comprehensive reference on eddy currents in theory and practice. It begins with an introduction to the underlying theory of eddy currents, before proceeding to both closed-form and numerical solutions, and finally describing current and future applications. The result is an essential tool for anyone whose work requires an understanding of these ubiquitous currents. Eddy Currents readers will also find: Professional insights from an author team with decades of combined experience in research and industry Detailed treatment of methods including finite difference, finite element, and integral equation techniques Over 100 computer-generated figures to illustrate key points Eddy Currents is a must-have reference for researchers and industry professionals in electrical engineering and related fields.

Download or read book Eddy Current Nondestructive Evaluation written by Nicola Bowler and published by Springer. This book was released on 2019-08-02 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the topic of eddy current nondestructive evaluation, the most commonly practiced method of electromagnetic nondestructive evaluation (NDE). It emphasizes a clear presentation of the concepts, laws and relationships of electricity and magnetism upon which eddy current inspection methods are founded. The chapters include material on signals obtained using many common eddy current probe types in various testing environments. Introductory mathematical and physical concepts in electromagnetism are introduced in sufficient detail and summarized in the Appendices for easy reference. Worked examples and simple calculations that can be done by hand are distributed throughout the text. These and more complex end-of-chapter examples and assignments are designed to impart a working knowledge of the connection between electromagnetic theory and the practical measurements described. The book is intended to equip readers with sufficient knowledge to optimize routine eddy current NDE inspections, or design new ones. It is useful for graduate engineers and scientists seeking a deeper understanding of electromagnetic methods of NDE than can be found in a guide for practitioners.
Download or read book Eddy Diffusion in the Antarctic Intermediate Water written by Albert Dennis Kirwan and published by . This book was released on 1964 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper the use of an eddy diffusivity tensor in the conservation of salt equation is investigated from two points of view. First it is found that the order of tensor assumed specifies the amount of information that can be obtained about the eddy flux. Secondly a method is developed for calculating each component of the eddy diffusivity tensor and/or its derivative from a record of the mean salinity and velocity fields. This method in essence treats the components of the diffusivity tensor as coefficients in a regression equation. This procedure allows confidence limits to be established for the tensor. In order to apply these results to observations from the ocean, an objective analysis scheme was developed. This scheme provided a means for estimating the salinity and geostrophic current fields along sigma t surfaces of the Antarctic Intermediate Water. The picture of the Intermediate Water obtained from this analysis is discussed and compared with the classic Meteor reports. Using this objective procedure, five different methods for calculating diffusivity were employed to determine the components of the diffusivity tensor. These methods included simple one dimensional diffusion, a balance of horizontal and vertical diffusion in the absence of a mean current, the general methods developed in this research which allowed for both horizontal and vertical mixing, and a finite difference scheme. The magnitude of the coefficients obtained by each of the different methods were comparable with each other and with those of previous investigators. However, in general the confidence limits on the estimates of the components of the diffusivity tensor were of the same order of magnitude as the estimates themselves. Significant improvement in the confidence limits was obtained by analyzing a much smaller region. An error analysis was made for the entire computational procedure. This analysis indicated that a combination of errors and/or terms neglected in the diffusion equation could account for the large uncertainties in the calculations.
