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 ...

This paper presents the modeling of high pressure discharge lamps, which are complex molecular systems, using COMSOL Multiphysics. The model accounts for the momentum, mass and energy conservation equations.

Solid extruded polymeric materials such as crosslinked polyethylene are widely used in the electrical insulation of underground high voltage power transmission cables. This paper treats the combined effect of space charge and cavities, on the electric field, and potential and temperature distribution within the insulation. The model is a 3D stationary linear COMSOL Multiphysics model and the ...
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).

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.

This paper summarizes the numerical contribution to a project for the detection of bioparticles present in a small volume of a liquid sample. Dielectrophoresis (DEP) is used to enhance their transport toward the surface of a detector. The mathematical model is composed of the electrokinetics equation for the DEP force-field calculation, and the advection-diffusion equation for the particle ...

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.

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 ...

In this paper, we create models with the use of COMSOL Multiphysics to predict evolution of temperatures and crust formation in meat during barbecuing and oven roasting. Sensitivity to parameters is analysed and predictions are compared to experimental data from literature.

In this paper, we investigate the compressional wave generation in droplets and use different techniques to correlate the compressional wave generation to the shape of the droplets. Results show a good correlation between eigenmodes predicted by the theory and those experimentally observed.
