Fluid Flow Simulation of Preconcentration Membranes Using Finite Elements Tools

R. Inglés[1], J. Pallares[2], J.L. Ramirez[1], and E. Llobet[1]

[1]Dept. of Electronic, Electrical and Automatic Control Engineering, Universitat Rovira i Virgili, Tarragona, Spain
[2]Department of Mechanical Engineering School of Chemical
Engineering Universitat Rovira i Virgili, Tarragona, Spain

We use finite elements simulations in order to study the fluid flow behavior in a chamber of a preconcentrator. We realized that most part of the fluid does not affect our preconcentrator because it is going out the chamber at high distance above it and parallel to the preconcentrator. ... En savoir plus

Thermo-fluid Dynamics Modelling of Hydrogen Absorption and Desorption in a LaNi_4.8Al_0.2 Hydride Bed

D. Baldissin[1] and D. Lombardo[1]
[1]Compumat S.r.l., Torino, Italy

A two-dimensional mathematical model for the absorption and desorption of H2 in LaNi4.8Al0.2 was developed and experimentally validated. The model is composed of an energy balance, a mass balance and a momentum balance. These differential equations are numerically solved by means of the ... En savoir plus

Chemical Reactions in a Microfluidic T-Sensor: Numerical Comparison of 2D and 3D Models

R. Winz[1][2], N. Schröder[1], W. Wiechert[1], and E. von Lieres[1]
[1]Institute of Biotechnology 2, Research Centre Jülich, Jülich, Germany
[2]Research Center for Micro and Nanochemistry, University of Siegen, Siegen, Germany

In recent years lab-on-microchip technology has become a powerful tool for micro-scale analysis of biochemical processes. In the studied system the overall process consists of transport, convection, diffusion, reaction and adsorption processes. Two compounds A and B, contained in a ... En savoir plus

Modeling Contact Line Dynamics in Evaporating Menisci

J. Plawsky[1], A. Chatterjee[1], and P.C. Wayner Jr.[1]
[1]Department of Chemical and Biological Engineering, Rensselaer Polytechnic Institute, Troy, New York, USA

The Constrained Vapor Bubble is a fundamental fluid mechanics experiment that is scheduled to run aboard the International Space Station starting in August 2009. The experiment is focused on looking at evaporation and condensation processes at the contact line, where vapor, liquid and ... En savoir plus

An Analysis of Heat Conduction with Change of Phase with Application to the Solidification of Copper

J. Michalski[1], and E. Gutirrez-Miravete[2]
[1]Hamilton-Sundstrand
[2]Rensselaer at Hartford, Hartford, Connecticut, US

The goal of this study was to determine the possibility of using the finite element in COMSOL Multiphysics program to obtain a high accuracy solution to a moving boundary problem, specifically, the solidification of copper. A one-dimensional geometry in Cartesian coordinates was used to ... En savoir plus

COMSOL® and MATLAB® Integration to Optimize Heat Exchangers Using Genetic Algorithms Technique

Genetic Algorithms (GA) have proved to be a complete and effective approach for solving optimization problems. This article presents the integration between COMSOL® and a GA optimization tool coded in MATLAB® for the optimization of two thermal systems: a constant area fin in 2D and a ... En savoir plus

Simulation of Manufacturing Process of Ceramic Matrix Composites

S. Yushanov, J. Crompton, and K. Koppenhoefer
ACES of Columbus, LLC, Columbus, OH, USA

Improved performance of aeroengines requires the development of new manufacturing technologies for ceramic matrix composites (CMCs). This has been simulated using COMSOL Multiphysics. Specialized simulation technologies have been developed to describe the infiltration of molten material ... En savoir plus

Non-Isothermal Kinetics of Water Adsorption in Compact Adsorbent Layers on a Metal Support

G. Füldner, and L. Schnabel
Fraunhofer Institute of Solar Energy Systems, Freiburg, Germany

Water adsorption in highly porous materials can be used in heat transformation processes for the efficient use of energy in heat and cold production. One technology for such a thermal heat transformation is the use of water adsorption in highly porous adsorbents like zeolite. To ... En savoir plus
