An MHD Modeling of High-Temperature SiC Solution Growth

F. Mercier[1], D. Chaussende[1], J.M. Dedulle[1,2] and J. Lefebure[1]
[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 ... En savoir plus

Blistering of Industrial Floors on Concrete Substrate: The Role of Air Overpressure

P. Devillers[1], S.V. Aher[2], G. Fau[3], B. Tranain[3], and C. Buisson[1]
[1]Centre des Matériaux de Grande Diffusion, Ecole des Mines d’Alès, France
[2]Department of Civil Engineering, Indian Institute of Technology Kanpur, Kanpur, Uttar Pradesh, India
[3]Centre Scientifique et Technique du Bâtiment, Champs sur Marne, France

A three dimensional COMSOL Multiphysics, transient analysis, diffusion model has been adopted to model the transfers of water in the industrial concrete floors. To take into account the different initial saturation levels at the different levels of the slab, the model is divided into ... En savoir plus

Designing a Smart Skin with Fractal Geometry

S. Ni, C. Yang Koh, S. Kooi, and E. Thomas
Institute for Soldier Nanotechnologies
Dept. of Materials Science and Eng.
MIT
Cambridge, MA

Recently, the concepts of fractal geometry have been introduced into electromagnetic and plasmonic metamaterials. With their self-similarity, structures based on fractal geometry should exhibit multi-band character with high Q factors due to the scaling law. However, there exist few ... En savoir plus

Sulfur Deactivation Effects on Catalytic Steam Reforming of Methane Produced by Biomass Gasification

P. Sadooghi[1], R. Rauch[1]
[1]Vienna University of Technology, Vienna, Austria

Sulfur, which is incorporated in the biomass structure, is released into the product gas during gasification as hydrogen sulfide. Hydrogen sulfide is known to deactivate nickel based steam reforming catalysts by chemisorption on the metal surface during steam reforming process. ... En savoir plus

Hierarchical Modeling of Polymer Electrolyte Membrane Fuel Cells

J. Dujc[1], J.O. Schumacher[1]
[1]Zurich University of Applied Sciences (ZHAW), Institute of Computational Physics (ICP), Winterthur, Switzerland

A finite element model of a polymer electrolyte membrane fuel cell (PEMFC) is described in this paper. We divide the PEMFC into two separate and parallel 2D regions which are connected by the 1D regions representing the membrane electrode assembly (MEA). COMSOL Multiphysics® was used as ...

Simulation of Formwork Filling by Cement Fluid: The Effect of the Formwork Structure on Yield-stress Fluid

J. Park[1], N. Banerjee[1], M. Alfi[1], D. Feys[1]
[1]Missouri University of Science & Technology, Rolla, MO, USA

The flow of self-consolidating concrete (SCC) in formwork fillings was simulated as the flow of a single phase yield-stress fluid between two infinite plates by COMSOL Multiphysics®. The flow of SCC with varied rheological properties (yield stress and plastic viscosity) was verified in ... En savoir plus

Cryogenic Heat Sink for Helium Gas Cooled Superconducting Power Devices

L. Graber[1], N.G. Suttell[1], D. Shah[1], D.G. Crook[1], C.H. Kim[1], J. Ordonez[1], S. Pamidi[1]
[1]Center for Advanced Power Systems, Florida State University, Tallahassee, FL, USA

Heat sinks for cryogenic applications using helium gas as the coolant are not readily available. They require to be designed specifically for the intended application. A finite element model was developed to study the feasibility and optimize the design. The FEM computing package COMSOL ... En savoir plus

Property and Performance Prediction of Meta Composites for Novel Applications

C. Thiagarajan[1]
[1]ATOA Scientific Technologies Private Limited, Whitefield, Bangalore 560066, India.

Metacomposites are new class of materials with unusual properties that can be engineered using existing materials with usual properties. The unusual properties of metacomposites are derived from the structure, analogues to atomic arrangement in crystal lattice. These material exhibits ... En savoir plus

Passive Cooling of Power Electronics: Heat in the Box

M. Berger[1], W. Schernus[1]
[1]West Coast University of Applied Sciences, Heide, Germany

Results presented are a contribution to the design of a 5kW-DC-AC-converter for applications in forklifts. The device is located in a closed environment and entirely operated with passive cooling. Due to concurrent engineering approach and environmental conditions correct prediction of ... En savoir plus

COMSOL Thermal Model for a Heated Neural Micro-Probe

M. Christian[1], S. Firebaugh[1], A. Smith[1]
[1]United States Naval Academy, Annapolis, MD, USA

This project utilizes the heat transfer module of the COMSOL Multiphysics environment to model the effects that an ohmic heating probe will have on neural tissue. The model quantifies the thermal impact of active components embedded on a neural micro probe by solving the Penne’s bioheat ... En savoir plus
