Computational Building Physics using Comsol: Research, Education and Practice

J. van Schijndel
Eindhoven University of Technology,
Eindhoven, The Netherlands

Jos van Schijndel completed his MSc in 1998 at the Department of Applied Physics at the Eindhoven University of Technology (TUe). In 2007 he obtained a PhD degree at the TUe on integrated heat, air and moisture modeling. Currently, he is assistant professor focusing on Computational ... Saiba Mais

Thermal Simulation of an Evaporation Reactor

H. Rouch, and S. Desbois
Villard de Lans, France

In this article we present Simulations results of an evaporation reactor for optical layer applications. The thermal simulation concern the source of the evaporated material. An experimental problem is ralated to the shape of the material powder surface: due to the evaporation rate, the ... Saiba Mais

Modelling Failure Mechanims in Sands Under Extreme Loads Using COMSOL

J. Mwebesa, D. Kalumba, and R. Kulabako
Makerere University
Kampala, Uganda

Studies by Nishaat (2009) showed that Terzaghi\'s bearing capacity model didn\'t adequately predict the bearing capacity failure in Philippi Dune sands. Nishaat carried out her investigation using a physical model that was built in a geotechnical laboratory. The failure surfaces she ... Saiba Mais

[1]Department of Micro- and Nanotechnology, Technical University of Denmark, Lyngby, Denmark
[2]Sunstone Capital, Copenhagen, Denmark

Lab-on-a-chip devices for cell culturing are becoming imperative in order to satisfy the needs for point-of-care or decentralized laboratory testing. Towards that goal we have developed miniaturized membrane based cell culture chambers for use within the field of chromosome analysis. The ... Saiba Mais

Fluid Structure Interaction Applied to Upper Aorta Blood Flow

J. Anza[1], and M. Esteves[2]
[1]Department of applied mathematics, University of the Basque Country, Bilbao, Spain
[2]University of the Basque Country, Bilbao, Spain

This work deals with the computer simulation of the blood flow, the arterial wall deformation and their 3D bidirectional interaction, including initial stresses and root displacements. The flow is laminar and steady with flexible walls modeled with a hyperelastic Demiray material ... Saiba Mais

COMSOL Multiphysics in Modeling MOCVDs

Y. Shimogaki
Shimogaki Laboratory
Department of Materials Engineering,
The University of Tokyo

This paper showed that: * SAG-MOCVD is a powerful tool to fabricate OEICs and is also effective to extract true surface kinetics during MOCVD. * GaAs-MOCVD process was examined by SAG analysis where it was seen that below 600ºC, surface kinetics shows non-linear behavior. * Surface ... Saiba Mais

The Gas Electron Multiplier (GEM) technology has been proven to tolerate rate larger than 50 MHz/cm² without noticeable aging and to provide the sub-millimeter resolution on working chambers up to 45x45 cm² [1]. A new GEM tracker is under development for the upgrade of the SBS ... Saiba Mais

Zero Dispersion Modeling in As2S3-Based Microstructured Fibers

P. Gagnon[1], H. Manouzi[1], M. El Amraoui[1], Y. Messaddeq[1]
[1]Laval University, Quebec City, QC, Canada

An important step in designing a microstructured optical fiber is the computation and management of its dispersion curve. It is well-known that computing chromatic dispersion can be done analytically for certain geometries (e.g. step-index fibers), but no such analytical methods is known ... Saiba Mais
