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 ... Read More

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 ... Read More

Fast 2D Simulation of Superconductors: A Multiscale Approach

V.M. Rodriguez-Zermeno[1], M.P. Sørensen[1], N.F. Pedersen[2], N. Mijatovic[2], and A.B. Abrahamsen[3]
[1]DTU Mathematics, Lyngby, Denmark
[2]DTU Electrical Engineering, Lyngby, Denmark
[3]Materials Research Division, Risø, DTU, Roskilde, Denmark

This work presents a method to calculate AC losses in thin conductors such as the commercially available second generation superconducting wires through a multiscale meshing technique. The main idea is to use large aspect ratio elements to accurately simulate thin material layers. For a ... Read More

Modeling of Silicon Transport into Germanium Using a Simplified Crystal Growth Technique

[3]Department of Mechanical Engineering, University of Constantine, Constantine, Algeria

A numerical simulation study, using COMSOL Multiphysics®, was carried out to examine the temperature and concentration fields in the dissolution process of silicon into germanium melt. This work utilized a simplified configuration which may be considered to be similar material ... Read More

Optimizing Bio-Inspired Flow Channel Design on Bipolar Plates of PEM Fuel Cells

X. Wang[1], J. Peitzmeier [2], and S. Kapturowski[3]
[1]Oakland University, Rochester, MI, USA
[2]Michigan Technological University, Houghton, MI, USA
[3]The State University of New York at Buffalo, Buffalo, NY, USA

The flow channel design on bipolar plates affects proton exchange membrane (PEM) fuel cell performance by influencing reactant distribution and water removal in an operating fuel cell. The fuel cell performance can be improved by varying the type, size, or arrangement of channels. Two ... Read More

Cavity Sprayer Flow Optimization for Medical Devices Industry

T. Selvam, V.P. Kotte, and M. Marimuthu

HCL Technologies Ltd, Chennai, Tamil Nadu, India

Globally in Otolaryngology industry, Sinusitis is one of the most common diseases related to the nose. Sinusitis is caused when the cilia fail to move the mucus. As a result sinus tissue gets infected that leads to blockage of the sinuses. All the sinusitis can not be cured through drugs ... Read More
