Fuel cells (FCs) are promising as an energy producing device, which at this stage of development will require extensive analysis and benefit from numerical modeling at different time- and length scales. COMSOL Multiphysics® is used to describe an intermediate temperature solid oxide fuel ... En savoir plus

In this paper, we present the numerical modelling of a free-burning arc and its application to the understanding of optical mirage effect which could occur in a TIG (Tungsten Inert Gas) device used in welding applications. En savoir plus

Predictive food microbiology currently first requires experimental data for growth on fresh produce and then fitting an empirical or semi-empirical model to the data, making extrapolation to other conditions (temperature, type of produce) difficult. Herein, we develop a mechanistic ... En savoir plus

Computational fluid dynamics (CFD) modeling is a useful tool to gain an insight into various high temperature metallurgical processes such as the magnesium refining and the magnesium solid oxide membrane (SOM) electrolysis. In both processes, argon gas was used to stir the molten salt ... En savoir plus

Single stage centrifugal pumps are widely used in several engineering fields such as: room conditioning, energetic cycles, automotive industry, home care, etc. Thus, the possibility of simulate their behaviour, in terms of pressure increase and mass flow rate, is helpful in reducing ...

We demonstrate cartogram construction, where a geographical map is distorted to represent some measure, for example population, while trying to keep the shape of regions recognizable. We then apply this cartogram construction technique to optimize thermocouple locations. A heat ... En savoir plus

In our project, we propose an innovative software solution to the problem of electrical arcing risk prediction in high-voltage on-board electronic equipment intended for long-term self-contained use, e.g. in spacecraft conditions. It completely based on so-called “decomposition” approach ... En savoir plus

This paper presents some results of numerical simulations carried out to investigate the basic hydrodynamic interactions between the laminar flow in the water column above triangular bedforms and the Darcian flow in the underlying permeable sediments. The flow was described by the Navier ... En savoir plus

The present study manifests the several ground breaking flow phenomena arising out of hydrodynamic interactions between two microorganisms swimming inside a microchannel with close proximity. The results theorized in the present investigation scrutinizes the varying behavior of the ... En savoir plus

Modeling and simulation softwares are very useful tools when we have to analyse and understand the different phenomena occurring during metal foams processing, because several simultaneous physical mechanisms have to be accounted for. In this work we use Comsol Multiphysics 4.2 to model ... En savoir plus
