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 ...

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).

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.

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.

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 ...

We present simulations of drops spreading on heterogeneous surfaces. The droplet height is the solution of a time-dependent non-linear fourth order partial differential equation, which is solved using COMSOL Multiphysics. In the fully wetting case, we compare our results with experimental data and with previous results reported in the literature. The simulation results reveal how ...

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.

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 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 ...
