COMSOL Multiphysics^® as a General Platform for the Simulation of Complex Electrochemical Systems

A. Lavacchi[1]
[1]Department of Chemistry, University of Firenze, Sesto Fiorentino, FI, Italy

Microelectrodes demonstrate that modeling is crucial for understanding the behavior of complex electrochemical systems. The use of the finite element methods in electrochemistry may be of much more general interest for its ability to handle complex geometries. In this context a ... 詳細を見る

Current Density Simulations in the Electrodeposition from Ionic Liquids: Effects of the Conductivity

I. Perissi[1], C. Borri[1], S. Caporali[1], and A. Lavacchi[1]
[1]Department of Chemistry, University of Firenze, Sesto Fiorentino, FI, Italy

The overall goal of this work is the use of COMSOL Multiphysics® in the modeling of the current density distributions for the electrodeposition of aluminum coatings from ionic liquids. The local current distribution is strongly dependant on the conductivity and on the geometry of the ... 詳細を見る

An Agglomerate Model for the Rationalisation of MCFC Cathode Degradation

[3]ENEA Casaccia, Dipartimento TER, Centro Ricerche Casaccia, S. Maria di Galeria, Roma, Italy

This paper describes the numerical modeling of a key material-stability issue within the realm of Molten Carbonate Fuel Cells (MCFC). The model describes the morphological and attending electrocatalytic evolution of porous NiO electrodes and is apt to predict electrochemical observables ... 詳細を見る

Large Scale 3D Flow Distribution Analysis in HTPEM Fuel Cells

C. Siegel[1][2], G. Bandlamudi[1][2], N. van der Schoot[1], and A. Heinzel[1][2]
[1]Zentrum für BrennstoffzellenTechnik GmbH, Duisburg, Germany
[2]Institut für Energie- und Umweltverfahrenstechnik, University of Duisburg-Essen, Duisburg, Germany

Accurate bipolar-plate and flow-field layout is one crucial task for optimizing fuel cells. These cell components perform several functions, including charge transport or gas and water transport throughout the cell just to name a few. Overall, the design depends on the fuel cell ... 詳細を見る

Contactless Excitation of MEMS Resonant Sensors by Electromagnetic Driving

M. Baù[1], V. Ferrari[1], and D. Marioli[1]
[1]Department of Electronics for Automation, University of Brescia, Brescia, Italy

A contactless electromagnetic principle for the excitation of mechanical vibrations in resonant structures has been investigated. The principle relies on no specific magnetic property of the resonator except electrical conductivity and can be adopted for employing the structures as ... 詳細を見る

Droplet Generation by Means of a Two-Fluid Probe

B.P. Cahill[1], M. Quade[1], G. Gastrock[1], K. Lemke[1], J. Metze[1], and D. Beckmann[1]

[1]Institut für Bioprozess und Analysenmesstechnik e.V., Rosenhof, Heilbad Heiligenstadt, Germany

This paper presents a simulation of the operation of a new type of droplet generation probe. This probe, consisting of two concentrically-arranged tubings, is immersed in a beaker of cell medium so that oil is pumped through the outer tubing at a pumping speed less than fluid is drawn ... 詳細を見る

Control of Rolling Direction for Released Strained Wrinkled Nanomembrane

P. Cendula[1], S. Kiravittaya[1], J. Gabel[1], and O.G. Schmidt[1]

[1]Institute for Integrative Nanosciences, Dresden, Germany

Strained wrinkled and flat nanomembranes have different bending properties when they are released from the underlying substrate. This is caused by increased bending rigidity of the wrinkled film in one direction. We provide theoretical and numerical analysis of the directional rolling of ... 詳細を見る

Thickness Optimization of a Piezoelectric Converter for Energy Harvesting

M. Guizzetti[1], V. Ferrari[1], D. Marioli[1], and T. Zawada[2]

[1]Dept. of Electronics for Automation, University of Brescia, Brescia, Italy
[2]Meggitt, Ferroperm Piezoceramics A/S, Kvistgaard, Denmark

The conversion of mechanical energy from environmental vibrations into electrical energy is a key point for powering sensor nodes toward the development of autonomous sensor systems. Piezoelectric energy converters realized in a cantilever configuration are the most studied for this ... 詳細を見る

Multiphysics Modelling of a Micro Valve

F. Bircher[1] and P. Marmet[1]

[1]Institute of Print Technology, Bern University of Applied Sciences, Burgdorf, Switzerland

Electromagnetic micro valves are currently developed empirically or the different physics are treated separately. To accelerate the development-process and for a better understanding of the overall system, a multiphysics simulation is built up. This simulation considers the ... 詳細を見る

Modeling Flow of Magnetorheological Fluid through a Micro-channel

N.M. Bruno[1], C. Ciocanel[1] and A. Kipple[2]
[1]Department of Mechanical Engineering, Northern Arizona University, Flagstaff, Arizona, USA
[2]Dept. of Electrical Engineering and Computer Sciences, Northern Arizona University, Flagstaff, Arizona, USA

This paper presents the approach taken through the utilization of COMSOL Multiphysics 3.5a, to develop a model that simulates the flow of a magnetorheological (MR) fluid through a micro-channel. The model was developed as an aid in the analysis of a micropump that produces flow by means ... 詳細を見る
