Multiscale models in low frequency electromagnetism

​Welcome to a seminar arranged by the Electromagnetics Laboratory (abbreviated EM-Lab), which is an assembly of senior researchers and teachers with activities in the scientific field of electromagnetics. EM-Lab is hosted by the Department of Electrical Engineering at Chalmers.​  ​
Speaker: Prof. Ruth V. Sabariego, KU Leuven, Dept. Electrical Engineering (ESAT), EnergyVille, Belgium

Title: Multiscale models in low frequency electromagnetism

Abstract: The behavior and performance of electromagnetic AC devices may be considerably altered by the eddy current effects (skin and proximity effects) in its (laminated iron) cores and windings. With the ever-increasing working frequencies in power converters, these high frequency effects cannot be neglected in the resolution stage of the FE modeling of electromagnetic devices (e.g. electrical machines, transformers, inductors). The classical a posteriori loss estimation becomes insufficient for certain design aspects. The eddy-current effects must be accounted for in the early stages of the design. For real-life applications, the 2D/3D modeling of the individual laminations/material structure and turns is excluded because of the huge computational cost. Alternative methods are thus indispensable. Homogenization methods are then indispensable and a viable alternative. That is the topic of this talk. 

Biography: Ruth V. Sabariego is currently associate professor with EnergyVille, Department of Electrical Engineering at the KU Leuven, Belgium. She graduated in Telecommunication Engineering in 1998 at the University of Vigo, Spain. In October 2000, she joined the Department of Electrical Engineering and Computer Science, University of Liège, Belgium, where she received the PhD degree in Applied Sciences in 2004 and stayed as a post-doctoral researcher till September 2013. Her primary area of expertise involves applied mathematics and computational electromagnetics with a current focus on multi-physics and multiscale modelling. She is (co-)author of some 230 journal and conference papers.
