Corrosion and contact ohmic resistance of the stainless steel current collectors in molten carbonates is one of the greatest obstacles to widespread application of molten carbonate fuel cells (MCFC). We simulate the variation of material parameters values, accounting for the impact of corrosion of the metallic current collectors on the performance of the porous cathode. Furthermore, we couple a ...

Modelling and Experimental Validation Possibilities of Heat Transfer Room Model

M. Zalesak, and V. Gerlich
Tomas Bata University in Zlin, Zlin, Czech Republic

The study presents first authors experience with COMSOL Multiphysics environment used as a possible modeling tool of thermal building behavior. The idea of the project was to gain thermal response to changed boundary conditions with the application of COMSOL environment as a modeling tool for 3D buildings or 3D building segments. The room as building segment was implemented in the COMSOL ...

Investigation Of Bone Marrow Stem Cells In The Bone Marrow Niche In An In Vitro System

P. Lezuo, M. Stoddart, and M. Alini
AO Research Institute, Davos, Grison, Switzerland

We aim to develop an in vitro culture system to mimic the human bone marrow stem cell niche in an artificial perfusion bioreactor environment to culture human adult stem cells. State of the art human bone marrow stem cell research shows that even smallest changes in the physical, thermo dynamical or biochemical environment induce a differentiation of human bone marrow stem cells into other cell ...

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 model. Poiseuille formula is used to check the bidirectional interaction. 2D axisymmetric and full 3D models have ...

Numerical Sensitivity Analysis of a Complex Glass Forming Process by Means of Local Perturbations

C. Janya-Anurak, T. Bernard, and H. Birkenhofer
Fraunhofer Institute of Optronics
System Technologies and Image Exploitation IOSB
Karlsruhe, Germany

Over the last few years, Finite Element Models have become increasingly important as tool for the design of process control strategies or process optimization. Some processes possess complex spatio-temporal coupled and nonlinear dynamic. For process optimization it is very important to know the impact of parameters and state variables to the relevant process “output” parameters. In the glass ...

Improving Fuel Usage in Microchannel Based Fuel Cells

P. Fodor, and J. D'Alessandro
Dept. of Physics
Cleveland State University
Cleveland, OH

In this work a miniaturized fuel cell design based on microchannels, into which the liquid fuel and oxidizer streams are fed through T shaped connectors, is optimized for improved fuel usage. This particular design exploits the laminar nature of the fluid flow at small Reynolds numbers to keep the fuel and oxidizer confined in the vicinity of the corresponding electrodes without the need of a ...

[1]Christian Michelsen Research, Bergen, Norway
[2]Luzmon Norway, Bergen, Norway
[3]Michelsen Medical, Bergen, Norway

The design challenge for thermostimulation equipment is to get a combination of high electric field strength and high temperature within the muscle tissue without causing pain or skin burns. In the present work, COMSOL Multiphysics is used to simulate the temperature distribution and electric field distribution within body tissue for varying body composition and varying design parameters of the ...

Laser Activated Gold Nanorods for the Photothermal Treatment of Cancer

F. Rossi[1], F. Ratto[1]
[1]CNR - Institute of Applied Physics "Nello Carrara", Sesto Fiorentino, Italy

Photothermal therapy through Gold Nanorods (GNRs) is a new approach for the minimally invasive treatment of cancerous tissue. In order to design the proper settings, it is important to study the thermal effect that are induced close to the nanoparticle (nanoscale model), in the close vicinity and in the cancerous tissue (microscale model). A temperature dependent 2D-model of this particular ...
