Modeling Magnetic Configurations for Improved Separations of Magnetic and Non-Magnetic Materials

S. Khushrushahi[1], T.A. Hatton[1], M. Zahn[1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

Magnetic separation of magnetic liquid phases/particles from non-magnetic liquid phases/particles are needed for applications such as cleaning up oil spills by separating oil and water liquid phases or separating magnetic materials from non-magnetic materials in biomedical and ... En savoir plus

Analysis of Dielectrophoretic Force by Using COMSOL

Taewoo Lee[1]
[1]Department of Biomedical Engineering, Yonsei University, Seoul, South Korea

Dielectrophoresis is a phenomenon in which a force is exerted on a dielectric particle when it is subjected to a non-uniform electric field. In this research, we analyze dielectrophoretic (DEP) force using a geometry containing two electrodes, one with SiO2 and one without, with a gap ... En savoir plus

Determination and Verification of the Forchheimer Coefficients for Ceramic Foam Filters using COMSOL CFD Modeling

M.W. Kennedy[1], K. Zhang[1], J.A. Bakken[1], R.E. Aune[1]
[1]Norwegian University of Science and Technology, Trondheim, Norway

Experiments have been conducted with water at velocities from ~0.015-0.77 m/s to determine the permeability of 50 mm thick commercially available 30, 40, 50 and 80 Pores Per Inch (PPI) Ceramic Foam Filters (CFF) used for liquid metal filtration. Measurements were made using two different ... En savoir plus

High Temperature Process Simulation

O. Geoffroy, and H. Rouch
INOPRO, Villard de Lans, France

The crystal growth industry uses high temperature processes. To improve production efficiency, a good knowledge of thermal effects is necessary. We show in this article a methodology to get reliable data by mixing simplified models, sensitivity studies and parameters adjustments. The ... En savoir plus

Fluid Dynamics Modeling of an Industrial Wet Chemical Process Bath for the Si-Solar Cell Production

L. Mohr [1], M. Zimmer [1], A. Moldovan [1], M. Menschick [2], B. Mandlmeier [2],
[1] Fraunhofer Institut for Solar Energy Systems ISE, Freiburg, Germany
[2] Singulus Technology AG, Fürstenfeldbruck, Germany

Silicon solar cells are produced in a series of different process steps in which wet-chemical etching and rinsing steps have a considerable influence on the quality of the wafers. Etching baths are used for surface structuring or intended etch back. Examples therefore are texturing, ... En savoir plus

Electrohydrodynamic Micropump Modeling for Performance Optimization

A. Mulye[1], S. Potnis[2]
[1]Northeastern University, Boston, MA, USA
[2]VIT, Mumbai, Maharashtra, India

We present an optimized and efficient design of an electrohydrodynamic (EHD) micropump for high performance in microscale and biological applications. We are targeting two major applications, a parylene C design for electrically-actuated medicine delivery, and a silicon-based pump design ... En savoir plus

Hybrid Resistive-Capacitive and Ion Drift Model for Solid Gas Dielectrics

Nils Lavesson [1], Charles Doiron [2],
[1] ABB Corporate Research, Västerås, Sweden
[2] ABB Corporate Research, Baden-Dättwil, Switzerland

INTRODUCTION: Many electrical insulation systems use a combination of gas and solid media. Typical examples considered here include the combination of solid epoxy insulation and SF6 in a gas insulated subsystem (GIS). To understand how such a system performs under DC voltages, accurate ...

COMSOL Multiphysics® Simulation of Energy Conversion and Storage Concepts Based on Oxide Crystals

C. Cherkouk[1], M. Zschornak[1], J. Hanzig[1], M. Nentwich[1], F. Meutzner[1], M. Urena[1], T. Leisegang[2], D. C. Meyer[1]
[1]Institute of Experimental Physics, Technische Universität Bergakademie, Freiberg, Germany
[2]Fraunhofer-Technologiezentrum, Freiberg, Germany

A mathematical model based on a finite element method (FEM) is presented as an initial approach for a system converting waste heat energy into chemical energy. This system consists of a pyroelectric LiNbO3 plate placed into a cylinder which undergoes a laminar water flow with an ... En savoir plus

Aerodynamic Analysis of a Ski Jumper: a CFD Approach

R. Latchman [1], A. Pooransingh [1],
[1] The University of the West Indies, St. Augustine, Trinidad and Tobago

At the 2006 Winter Olympics, the jump length difference between first and second place was only 5cm. This illustrates why ski jumpers are constantly tinkering with their posture in order to gain even the smallest of advantages. Experiments such as those shown in Figures 1 and 2 (b), ...
