A Multiphase Model to Analyze Transport Phenomena In Convective Drying

S. Curcio, and M. Aversa
Department of Engineering Modelling, University of Calabria, Rende, Italy

In the modern food industry one of the most important problems to face is to preserve products from deterioration: a widely used solution is the convective foods drying. Drying is based on a simultaneous transfer of both heat and water that takes place when dry and warm air flows around ... Mehr lesen

Solid Oxide Fuel Cell Material Structure Grading in the Direction Normal to the Electrode/Electrolyte Interface Using COMSOL Multiphysics®

M. Andersson[1], B. Sundén[1]
[1]Department of Energy Sciences, Lund University, Lund, Sweden

Fuel cells (FCs) are promising as an energy producing device, which at this stage of development will require extensive analysis and benefit from numerical modeling at different time- and length scales. COMSOL Multiphysics® is used to describe an intermediate temperature solid oxide fuel ... Mehr lesen

Bio-Effluents Tracing in Ventilated Aircraft Cabins

G. Petrone[1], L. Cammarata[1], and G. Cammarata[1]
[1]Department of Industrial and Mechanical Engineering, University of Catania, Catania, Italy

Ventilation and Indoor Air Quality (IAQ) are issues of very high interest, determining comfortable conditions for occupants and no-contaminated local atmosphere. The aircraft cabins are more confined and have a higher occupant density than other indoor environments such as offices or ... Mehr lesen

The use of plasmas for the treatment industrial effluents provides a new alternative to the decontamination of wastewater. The strong oxidizing species (O,O3, OH) generated by the plasma, at room temperature, can oxidise organic pollutants present in the water. Our simulation deals with ... Mehr lesen

Scattering of mm-Waves by Turbulent Structures in Magnetically Confined Fusion Plasmas

O. Chellaï [1], S. Alberti [1], I. Furno [1], T. Goodman [1], M. Baquero [1]
[1] Centre de Recherches en Physique des Plasmas, Ecole Polytechnique Fédérale de Lausanne, Suisse

In magnetically confined fusion devices, electron cyclotron resonance heating (80-170 GHz) is characterized by a local RF-power deposition at the electron cyclotron resonance [1]. A mm-wave RF Gaussian beam is launched from a dedicated antenna and propagates through the highly turbulent ... Mehr lesen

Lamb Waves and Dispersion Curves in Plates and It’s Applications in NDE Experiences Using Comsol Multiphysics

P. Gómez, J. P. Fernandez, and P. D. García
Hydro-Geophysics & NDE Modeling Unit
University of Oviedo
Mieres, Spain

In this paper, a model for numerically obtaining lamb wave modes and dispersion curves in plates is presented. It is shown that COMSOL Multiphysics can be employed to simulate the behavior of guided waves in dispersive plates, which is useful for NDE applications. A two dimensional ... Mehr lesen
