Rotating Magnetic Field Eddy current technique is a promising technique for inspection of flaws in metallic tubular components. Three primary coils, 120 degrees apart in space, are excited with three phase current source, by virtue, a rotating magnetic field polarised in radial direction is generated. This radial field interacts with metallic tube and generates ...

Interactions of Magnetic Particles in a Rotational Magnetic Field

A. Weddemann, A. Auge, F. Wittbracht, S. Herth, A. Hütten
Bielefeld University, Germany

Particle-particle interactions are usually neglected when considering the behaviour of magnetic particle's so called magnetic beads in e.g. a microfluidic device. However, if the particle density exceeds a critical limit, this assumption might not lead to proper results anymore. In this paper the particle-particle interaction of magnetic beads in an external magnetic field will be discussed. It ...

Using COMSOL Multiphysics in Eddy Current Non Destructive Testing Context

L. Santandrea, and Y. Le Bihan
Laboratoire de Génie Electrique de Paris, Gif-sur-Yvette, France

Eddy current testing (ECT) is widely used to check the integrity of electrically conducting parts and notably to detect flaws. It is based on the interaction between a probe and the part under testing. The finite element method (FEM) is well fitted to the modelling of these kinds of problems because of its large flexibility which allows to deal with complex probe and part configurations. In this ...

High temperature super conducting (HTS) cables are gaining attentions for their ability to transmit more power compared to their convention counterparts with essentially no resistance and electromagnetic emissions. They are also appropriate for solving the grid congestion problem in the power corridors with their reduced size and weight. But the AC loss that occurs in the HTS cables reduces the ...

Estudo Numérico da Eletroquimioterapia em Tumor Cutâneo com Diferentes Configurações de Eletrodos - new

A eletroquimioterapia é um tratamento de câncer que utiliza a combinação de agentes quimioterápicos e campos elétricos. A base teórica por trás dessa aplicação é a eletroporação. Esse fenômeno biológico consiste na abertura de poros na membrana celular devido à aplicação de pulsos elétricos. Este trabalho analisa o comportamento do campo elétrico gerado por pulsos elétricos aplicados em ...

FEM Modeling in Robust Design for Graphene-Based Electromagnetic Shielding

S. Elia [1], G. Granata [1], P. Lamberti [1], V. Tucci [1],
[1] University Of Salerno, Italy

Electromagnetic shielding design is usually approached referring to nominal values of the main parameters. This could lead to malfunctioning devices and its performance differ widely from what was really aimed at or, worse, the final design product could even be physically unrealizable. This work presents a robust approach to the design of EM Shielding based on Graphene (Gph) layers. It is a two ...

Computation of Electrical Parameters for Different Conducting Bodies Using Finite Element Method

S. Musa and M. Sadiku
College of Engineering, Prairie View A&M University, Prairie View, TX, USA

Accurate and efficient computation of electrical parameters for different conducting bodies represents an essential part of spacecraft modern integrated circuits. In this paper, we will illustrate modeling of inhomogeneous quasi-TEM shielded rectangular, cylindrical, and triangular transmission lines using COMSOL Multiphysics. Excellent agreement with some results obtained previously is ...

[1]Laboratoire des Matériaux et du Génie Physique (LMGP), Grenoble INP - CNRS, France
[2]IRIS Technologies, Grenoble, France

Despite its real advantages compare to seeded sublimation growth, SiC solution growth has never given convincing results. The difficulty of stabilizing the growth front, and thus avoiding any polycrystal formation results from a poor description and understanding of the coupled phenomena that occur in the crucible. This paper addresses the coupled electromagnetism, heat transfer and fluid ...
