Numerical Modelling of Eddy Currents (Hardcover). This item is unavailable.Numerical Modelling of Eddy Currents (Hardcover)

Hardcover. Great progress has been made in developing and using numerical methods for solving electromagnetic field problems at low frequency recently. Many of these problems refer to eddy currents which appear in various electromagnetic devices.Originally such problems were tackled by analytical solutions which are limited to simple geometries and linear materials. In practice though all electromagnetic devices have complex boundaries, includenon-linear materials, and may be treated exclusively by numerical methods.This book gives systematically the matehmatical simulation of existing methods and discusses thesiscretization of relevant equations. The methods described are: finite difference, finite sums, finite element, boundary element, and some variants. Physical connotations of methods and problems are also given. Eddy currents appear in electromagnetic devices (e.g. the cores of transformers or rotors in electric motors) whenever a magnetic field varies through a conductor. Very often they are undesirable representing a power loss. The prediction of eddy currents is therefore of great practical importance. This book looks at numerical modelling methods for the prediction of eddy currents. This item is printed on demand.
