Detection of Pressure or Flow Rate Variations in MR Valves through Magnetic Flux Analysis

Yves Perriard, Yoan René Cyrille Civet, Daniel Grivon

Magneto-Rheological (MR) fluids consist in a suspension of ferromagnetic particles dispersed in a fluid carrier. If excited by a magnetic source, the nearby magnetic field induces the particles magnetization with the formation of chainlike structures align ...

This communication extends a previously reported analytical circuit that models the plane wave scattering by 2-D arrays of planar patches/apertures embedded in a layered media. In this extension, it is assumed that the current/electric field spatial profil ...

Leakage Flux Modelling of Multi-Winding Transformer using Permeance Magnetic Circuit

Drazen Dujic, Min Luo, Jost Allmeling

The size and position difference of the windings determine the leakage flux path and give rise to unbalance of the short-circuit impedances, which strongly affects the transient behaviour of the transformer. This work proposes a new approach of modelling w ...

Equivalent Admittance Approach for the Scattering of Patch/Slot-Based Frequency Selective Surfaces

Juan Ramon Mosig, Maria Garcia Vigueras

The equivalent admittance of a 2-D array of printed metallic patches/apertures is obtained here by extending a precedent equivalent circuit approach reported by some of the authors. The goal of the present extension is to cover more complex situations like ...

Dynamic cantilever magnetometry of individual CoFeB nanotubes

Anna Fontcuberta i Morral, Dirk Grundler

We investigate single CoFeB nanotubes with hexagonal cross section using dynamic cantilever magnetometry (DCM). We develop both an analytical model based on the Stoner-Wohlfarth approximation and a broadly applicable numerical framework for analyzing DCM m ...

2016

Lumped magnetic circuit provides possibility for fast transient simulation of magnetic component together with power electronics circuit. The simplified geometry representation however is not able to completely reflect the real field distribution, especial ...

AC Magnetoelectrical Susceptibility Study of Multiferroics

Abhisek Datta

Multiferroics are materials in which ferroelectric and magnetic e.g., ferromagnetic or antiferromagnetic orders co-exist. Some of these show the magnetoelectric effect which is the coupling between electric and magnetic degrees of freedom leading to induct ...

Cu codoping control over magnetic precipitate formation in ZnCoO nanowires

Simon Granville

Using electrodeposition, we have grown nanowires of ZnCoO with Cu codoping concentrations varying from 4-10 at. %, controlled only by the deposition potential. We demonstrate control over magnetic Co oxide nano-precipitate formation in the nanowires via th ...

Fluid Flow Analysis of a New Finned Piston Reciprocating Compressor Using Pneumatic Analogy

Alfred Rufer, Mahbod Heidari

The goal of this paper is to investigate the fluid flow analysis in a novel multilayered finned reciprocating compressor, adopting a so-called “pneumatic-Electric” analogy using a lumped methodology. This machine includes two sets of concentric annular fin ...
