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 ... En savoir plus

Modeling Nanoscale Heat Flow

S. Palaich, and B. Daly
Physics and Astronomy Department, Vassar College, Poughkeepsie, NY, USA

When the dimensions of the material approach is a comparable size to the phonon mean free path, heat flow enters a new regime, the nanoscale. The Fourier and Cattaneo Equations describe bulk heat flow well, but radiative boundary terms must be considered when modeling nanoscale heat ... En savoir plus

COMSOL Multiphysics® Bio-Cellular Tunneling Model

E. Lacatus [1],
[1] Polytechnic University of Bucharest, Romania

The emerging technologies related to AI and Quantum Computing are shifting the nano-bio-info paradigm, reconsidering the presently assumed bioenergetic processes of the living cells. Thus, a key process as ATPase can be considered through a model governed by quantum field theory (QFT) ... En savoir plus

Modeling the Swirling Flow of a Hydrocyclone

B. Chine' [1], F. Concha [2], M. Meneses [3],
[1] Costa Rica Institute of Technology, School of Materials Science and Engineering, Cartago, Costa Rica
[2] Departamento de Ingeniería Metalúrgica, Universidad de Concepción, Concepción, Chile
[3] Costa Rica Institute of Technology, School of Industrial Production Engineering, Cartago, Costa Rica

Hydrocyclones are industrial devices used as processing units in fluid and particle technology. A hydrocyclone is an apparatus consisting of a cylindrical or a cylindrical-conical body with a tangential or involute entrance to admit the fluid inside. There are also two opposite exits, ...

Design of Arrayed Micro-Structures to get Super-Hydrophobic Surface for Single Droplet and Bulk Flow Conditions

A. Mall[1], P. R. Jelia[1], A. Agrawal[1], R. K. Singh[1], and S. S. Joshi[1]

[1] Department of Mechanical Engineering, Indian Institute of Technology Bombay, Maharashtra, India

Surfaces with water contact angle greater than 150º are super-hydrophobic in nature and possess extraordinary water repelling properties. Various researches on wettability of textured surfaces in recent years have shown that texturing surfaces with micron-sized and nanosized patterns ... En savoir plus

COMSOL Multiphysics® Based Identification of Thermal Properties of Mesoporous Silicon by Pulsed Photothermal Method

N. Semmar[1], I. El Abdouni[1], A. Melhem[1]
[1]GREMI-UMR7344, CNRS/University of Orléans, Orléans, France

The silicon is mainly known under its single-crystal shape and polycrystalline. Since a few decades, a new type of morphology is developed: the porous silicon (p-Si). Meso-porous silicon (Mp-Si) is one of promising materials for future microelectronic chips multi-functionalization ... En savoir plus

Determination of the Mechanical Properties in the Avian Middle Ear by Inverse Analysis

P. Muyshondt[1], J. Soons[1], D. de Greef[1], J. Peacock[1], J. Dirckx[1]
[1]University of Antwerp, Antwerp, Belgium

The middle ear of birds is a fascinating mechanical system, as it contains only one bony ossicle, compared to three in mammals, yet its auditory performance is not substantially worse. Its design resembles some currently used middle ear prostheses, so the understanding of its working ... En savoir plus
