Numerical Modeling of Falling Aluminum Particle Oxidation in Air

A. Davidy
Israel Military Industry, Ramat-Hasharon, Israel

Because of its high enthalpy of combustion, aluminum has been added to energetic materials. In this paper, a two dimension thermal model is developed and assessed to describe the interrelated processes of Aluminum particle oxidation by using the software COMSOL Multiphysics. The thermal ...

Simulation Of Soil Remediation Polluted By Hydrocarbons Using A Non-Thermal Atmospheric Plasma

J. Rojo, S. Ognier, and S. Cavadias
Laboratoire de Génie des Procédés Plasmas et Traitements de Surfaces, University Pierre et Marie Curie, Paris, France

A lot of techniques are developed to treat soils polluted by hydrocarbons pollutants: incineration, thermal treatment, extraction, chemical oxidation, bioremediation… Some of these techniques are very energy consuming (incineration, thermal treatment…) and often need a subsequent ...

Simulation of Chemotractant Gradients in Microfluidic Channels to Study Cell Migration Mechanism in Silico

P. Wallin[1], E. Bernson[1], J. Gold[1]
[1]Chalmers University of Technology, Applied Physics, Biological Physics, Gothenburg, Sweden

Cell migration of endothelial cells along gradients is an important process in vivo and an interesting target for cancer therapeutics. Microfluidics offer very powerful tools to study such migration processes in detail in the lab. In this study, we describe a model to simulate molecular ... En savoir plus

Finite Element Study of the Mass Transfer in Annular Reactor

Y. M. S. El-Shazly[1], S. W. Eletriby[1]
[1]Alexandria University, Alexandria, Alexandria, Egypt.

The annular reactor is a very useful design to carry many chemical reactions. In this study, COMSOL Multiphysics® software was used to study the isothermal mass transfer from the inner side of the outer tube of the annular reactor in the range of 200 En savoir plus

Studying PEM Fuel Cells using Equation Based Simulation

J. Blackburn [1], N. McCartney [1],
[1] National Physical Laboratory, London, UK

We present computer simulation results for PEM fuel cells using COMSOL Multiphysics® software. We have developed novel PDE equations at NPL from first principles and these are more realistic than models typically used in literature. The theory includes Maxwell-Stephan and Nernst-Planck ...

Design of an Anisokinetic Probe for Sampling Radioactive Particles from Ducts of Nuclear Facilities

P. Geraldini [1],
[1] Sogin Spa, Rome, Italy

The aim of this study is to design a new concept of shrouded probe that meets the ISO 2889 requirements and it is suitable for small-ducts installation. In order to reduce the construction costs they have been considered standard stainless steel welding fittings manufactured according to ... En savoir plus

Simulation of a Nozzle in a Borehole

E. Holzbecher [1], F. Sun [2],
[1] German University of Technology in Oman, Muscat, Oman, Germany
[2] Georg-August-Universität, Göttingen, Germany

In boreholes nozzles have to be found advantageous to increase the infiltration rate of water into the subsurface ground. Studies and practice in the field shows that the infiltration of water into permeable aquifers can be improved, if the flow in the borehole is modified. Due to the ... En savoir plus

CFD/Electromagnetics Interactions via Realistic Heat and Mass Transfer to Moist Substrates

G. Ruocco[1], M. V. De Bonis[2]
[1]Engineering College, University of Basilicata, Potenza, Italy
[2]Institute of Food Science and Production, National Research Council, Bari, Italy

Localized convection heat and mass transfer can be intensified and optimized by providing exposure to electromagnetic energy. Conjugate heat and mass transfer are configured by solving the momentum, heat and mass transfer simultaneously in both solid (substrate, comprising of a two-phase ... En savoir plus

Design, Fabrication and Simulation of Microchannel Network for MEMS

V. Jain[1], A. K. Sharma[2], P. Kumar[2]
[1]Thapar University, Patiala, Punjab, India
[2]Indian Institute of Technology Roorkee, Roorkee, Uttar Pradesh, India

The greatest challenge being faced for realization of Micro-Electro Mechanical System (MEMS) technology is the lack of a simple, quick and reliable method for the fabrication of 3-D microchannel in the range of micrometers. A novel fabrication technique which opens possibilities for the ... En savoir plus

Transport Phenomena and Shrinkage Modeling During Convective Drying of Vegetables

S. Curcio[1] and M. Aversa[1]
[1]Department of Engineering Modeling, University of Calabria, Arcavacata di Rende, CS, Italy

The aim of the present work is the formulation of a theoretical model describing the transport phenomena involved in food drying process. The attention has been focused on the simultaneous transfer of momentum, heat and mass occurring in a convective drier where hot dry air flows, in ... En savoir plus
