Flow Accelerated Corrosion (FAC) of carbon steel has been studied world-wide for more than twenty years and is now fairly well understood. The influence of several parameters like water chemistry (pH, dioxygen content), temperature, hydrodynamic or mass transfer conditions (flow velocity, geometry) and steel composition on the corrosion kinetics has been demonstrated both theoretically (“Berge ...
Low-pressure glow discharges are of topical interest for a lot of technological applications like plasma light sources, plasma processing for surface modification, and plasma chemistry. Therefore, a detailed understanding of the fundamental processes of glow discharges is required to e.g. optimize the discharge parameters in these plasma applications. Theoretical investigations can help to ...

Les décharges luminescentes à pression atmosphérique sont étudiées expérimentalement en laboratoire pour la valorisation des alcanes et notamment la production d'hydrogène à partir du méthane. La modélisation des dispositifs usuels est complexe compte tenu de l'aspect non stationnaire des décharges. Afin d'évaluer le poids des paramètres de réglage d'un réacteur nous avons ...

Designers of electromagnetic and electromechanical devices often need to predict external magnetic fields of devices with good accuracy. This paper considers a less common approach to the open boundary problems, which is built on the spatial harmonic analysis (SHA) of the field over a basis boundary of the finite element (FE) domain. It is important that the spatial harmonic analysis of complex ...
Computations of the earth’s and other solar planets’ magnetic moments with the aid of a FEMLAB electromagnetic module
Retired, Hughes Space & Communications Co. (Now Boeing Co.)
Computations have been performed of Earth’s and other solar planets’ magnetic moments with the aid of a FEMLAB Electromagnetic Module. The FEMLAB library has a specific program that calculates magnetic field strength and distribution resulting from a circular current source. This program has been adapted with 38 concentric loops to simulate the conductive currents circulating within the ...

This paper presents and discusses HazRes’ research and results associated with the simulation and modelling of hydrogen release and dispersion events in indoor enclosed environments, using COMSOL Multiphysics. HazRes has developed a gas dispersion model in COMSOL, which takes into account the effects of buoyancy, localized ventilation effects and turbulence generated by obstacles on the ...
Boundary Conditions Identification for Thermostatic Cauchy Problem by Minimizing an Energy-like Function
LDMS, UMR CNRS-INSA 5006, ISTIL - Université Claude Bernard, Lyon
An energy-like error function is introduced in the context of the ill-posed problem of boundary data recovering, which is commopnly known as a Cauchy problem. Here the problem is converted into an optimization problem. Numerical simulations highlight the efficiency and robustness of the proposed method.

This presentation is concerned with the modelling of deformable non-Newtonian Flow using COMSOL Multiphysics. This general modelling approach has more concrete applications such as paper coating in a metering size press, meniscus location by PIDS to mention a few.

The mathematical modeling of the diffusion and reaction of toxic compounds in mammalian cells is tough task due to their very complex geometry. The heterogeneity of the cell, particularly the cytoplasm, and the variation of the cellular architecture, greatly affects the behavior of these toxic compounds. Homogenization techniques have been implemented for the numerical treatment of the model. ...

The evaporation process of microscopic drops was investigated by depositing them onto atomic force microscope (AFM) cantilevers and measuring the deflection of the cantilever in response to the presence of the drop. We could thus improve a previously presented FE simulation model by comparing the simulations of the cantilever’s transversal deflection to 3-D images of the cantilever’s ...
