Mathematical Models for Eddy Currents and Magnetostatics: With Selected Applications (Scientific Computation)

This monograph addresses fundamental aspects of mathematical modeling and numerical solution methods of electromagnetic problems involving low frequencies, i.e. magnetostatic and eddy current problems which are rarely presented in the applied mathematics literature. In the first part, the authors introduce the mathematical models in a realistic context in view of their use for industrial applications. Several geometric configurations of electric conductors leading to different mathematical models are carefully derived and analyzed, and numerical methods for the solution of the obtained problems are given. Related issues such as convergence of the approximations and error estimates are discussed. The second part of the monograph presents various coupled problems that involve eddy current or magnetostatic problems, in particular magneto-hydrodynamic problems and magnetic shaping problems concerning the melt flow of electrically conducting metals, induction heating processes, inductively coupled plasmas and ferromagnetic screening modeling. The presentation of each model comes with numerical illustration from industrial applications.

Prof. Jaquez Rappaz is a professor of mathematics at the Chair of Numerical Analysis and simulation, Institute of Analysis and Scientific Computing EPFL in Lausanne, Switzerland. His list of publications including about 100 journal and proceedings papers mainly features contributions to journals related on applied mathematical modeling, numerical analysis (e.g. ZAMM, Numerische Mathematik) and computational physics. Prof. Rachid Touzani is a professor of Applied Mathematics at the Polytech' Clermont-Ferrand - Universite Blaise Pascal, Aubiere, France. His expertise are the topics of magneto-hydrodynamics including liquid metal flow, free boundary problems, and induction heating and models with thin inductors (according to his webpage http: //math.univ-bpclermont.fr/ touzani/) which make up the "application" chapters 8 to 12 in the book draft under consideration
