The students at ESPNG have, since 2002, been using COMSOL Multiphysics in order to master physical phenomena and the finite element method. We developed several projects based on the modeling of physics phenomena, and, in this paper, we present projects based on Physical Vapor Transport and Magnetic Levitation. --------------------------------- Keynote speaker's biography: Jean-Marc ...
Numerical Simulation of Moving Boundary Problems with the ALE Method: Validation in the Case of a Free Surface and a Moving Solidification Front
Université de Bretagne Sud
This work investigates numerical simulations of problems involving moving boundaries. The first case concerns the simulation of incompressible Newtonian fluid flow problems with free surfaces in the presence of surface tension (the sloshing problem). The second case deals with a problem of heat transfer in the presence of an advancing solidification front (the Stefan problem).

Our work is to improve the surface texturing process by laser irradiation. In this study, thermal modelling of the laser-matter interaction for a single laser impact case is presented. A 1D modelling was carried out. The purpose was to determine the dimension of the liquid layer and the ablated matter volume. The model accounts for the evolution of material thermodynamic properties, the ...

Various models, based on mass transfer and different isothermal adsorption equilibrium laws, are developed using COMSOL Multiphysics. These isotherms are representative of the adsorption of various pollutant-adsorbent systems frequently found in decontamination processes. Consequences on breakthrough curves are examined and possible applications to decontamination processes are discussed.

This paper deals with the Cage System, developed by Roctool, which heats and transforms composite materials. The simulation shows the importance of the inductor design and position relative to the mold.

In this paper we use the COMSOL Heat Transfer Module to simulate the radiative and conductive heat transfer in an experimental oven fitted with electrical infrared emitters. In particular, we study paint curing temperature and compare our results to experimental data.

In this paper we propose a finite element model (FEM), to solve the micro-magnetic equations. Two bi-dimensional test problems are treated to estimate the validity and the accuracy of this approach.

In this paper, we introduce a kinetic equation coupled with the Navier-Stokes equations in COMSOL Multiphysics in order to simulate internal structural changes of a flowing complex fluid. Two physical applications are considered, the starting of blood flow in a stenosis and a simulation of a laboratory rheometric set-up. Results show good agreement with the experiments' well known ...

Thermoplastic polymers are frequently used in several industries, and represent the most important group of polymeric materials. During the injection moulding process, the cooling phase including solidification is often the most significant part of the manufacturing cycle. In this paper we study the coupling phenomena between the crystallization and the thermal kinetics in the polymer ...

In this paper, we present the modeling of catalytic reactions under non-steadystate conditions. Particularly, we study the Fisher-Tropsch reaction in a pulse reactor.
