Microalgae Cell Separation and Concentration in a Microfluidic Channel Under Dielectrophoresis (DEP) Effect

A. Barai[1], N. Boldt[2], M. Birkholz[1]
[1]IHP - Leibniz-Institut für innovative Mikroelektronik, Germany
[2]Technische Universität Berlin, Germany

Microalgae biomass is an essential part of the global ecosystem. Not only is it responsible for 50% of the global oxygen but also proved to be useful in the development of organic polymers, antioxidants, pharmaceuticals, and feedstocks for aquatic animals. It is considered as an ... En savoir plus

Design and Manufacturing of A Linear Induction Motor for the 2019 EPFloop Prototype in the Framework of the SpaceX Hyperloop Competition

A. Hodder[1], S. Rametti[1], N. Bollier[1], M. Seydoux[1], T. Dimier[1], M. Jufer[1], L. Benedetti[1], N. Riva[1]
[1]EPFLoop, Switzerland

The EPFLoop team from Ecole Polytechnique Fédérale de Lausanne has developed a capsule thanks to which it won the 3rd place in SpaceX’s Hyperloop Pod Competition in 2018. This year the EPFLoop team has been selected again to participate at the 2019 Competition held at the SpaceX ... En savoir plus

MultiPhysics Analysis of Trapped Field in Multi-Layer YBCO Plates

P. Masson[1], and R. Meinke[1]
[1]Advanced Magnet Lab, Palm Bay, Florida, USA

Superconductors have the unique capability of trapping magnetic flux. This feature has the potential to enable and improve several applications including high power density rotating machines. Current material used as trapped flux magnets (TFM) is single domain YBCO that present numerous ... En savoir plus

FE Modeling of Surfaces with Realistic 3D Roughness: Roughness Effects in Optics of Plasmonic Nanoantennas

J. Borneman[1], A. Kildishev[1], K. Chen[1], and V. Drachev[1]

[1]School of Electrical and Computer Engineering and Birck Nanotechnology Center, Purdue University, West Lafayette, Indiana, USA

COMSOL Multiphysics has been widely used to model the near and far-field electromagnetics (specifically, transmission and reflection spectra) of gold and silver nanoantenna arrays. We use a moving 3D mesh, thus preserving the DOF number and simply morphing the structure of the mesh ... En savoir plus

Multiphysics Modelling of a Micro Valve

F. Bircher[1] and P. Marmet[1]

[1]Institute of Print Technology, Bern University of Applied Sciences, Burgdorf, Switzerland

Electromagnetic micro valves are currently developed empirically or the different physics are treated separately. To accelerate the development-process and for a better understanding of the overall system, a multiphysics simulation is built up. This simulation considers the ... En savoir plus

Particle Flow Control by Magnetically Induced Dynamics of Particle Interactions

F. Wittbracht[1], A. Weddemann[1], A. Auge[1], and A. Hütten[1]

[1]Department of Physics, Thin Films and Physics of Nanostructures, Bielefeld University, Bielefeld, Germany

In this work, we show that dipolar magnetic coupling can be used to control the particle flow through microfluidic structures without changing the state of motion of the carrier liquid. Also no external magnetic gradient fields are employed; the total external magnetic force applied is ... En savoir plus

The Optical Properties of a Truncated Spherical Cavity Embedded in Gold

A. Pors[1], O. Albrektsen[2], S.I. Bozhevolnyi[2], and M. Willatzen[1]
[1]Mads Clausen Institute, University of Southern Denmark, Sønderborg, Denmark
[2]Institute of Sensors, Signals and Electrotechnics, University of Southern Denmark, Odense, Denmark

The use of plasmonic effects to dramatically enhance the electromagnetic field near the surface of a metallic nanostructured surface has grown into a large research area in the effort to take advantage of the surface enhanced field. In this paper the electromagnetic field near a nano ... En savoir plus

Accuracy of Fully Coupled Loudspeaker Simulation Using COMSOL

M. Hedges[1][2] and Y.W. Lam[1]
[1]Acoustics Research Centre, School of Computing, Science & Engineering, University of Salford, Salford, United Kingdom
[2]Monitor Audio Ltd., Rayleigh, Essex, United Kingdom

Loudspeaker simulation is used to inform the designer as to the performance of a design. In recent years the Finite Element Method (FEM) has been used to model the mechanical and acoustical attributes of a loudspeaker with varying success. This paper shows how a model that incorporates ... En savoir plus

A Model for High Temperature Inductive Heating

S.A. Halvorsen[1]
[1]Teknova AS, Kristiansand, Norway

COMSOL Multiphysics has been applied to develop a model for inductive heating. A coarse, lumped model of the interior of a high temperature reactor is coupled to finite element models for the electromagnetic field, the temperature distribution outside the reactor, and mechanical stresses ...

Modelling of SiC Chemical Vapour Infiltration Process Assisted by Microwave Heating

G. Maizza[1] and M. Longhin[1]
[1]Dipartimento di Scienza dei Materiali ed Ingegneria Chimica, Politecnico di Torino, Torino, Italy

The excessive presence of residual SiC matrix inter-fiber pores is often the main cause for the very poor mechanical strength and toughness of SiC/SiC composites manufactured by CVI (Chemical Vapour Infiltration) process. This work presents a micro/macro Microwaveassisted Chemical Vapour ... En savoir plus
