A model of a Molten Carbonate Fuel Cell (MCFC) stack with internal reforming is presented. It describes the concentrations in the gas phase, the temperatures and the current densities in this highly integrated system. The differential equations, boundary conditions and the coupling ...

Water adsorption in highly porous materials can be used in heat transformation processes for the efficient use of energy in heat and cold production. One technology for such a thermal heat transformation is the use of water adsorption in highly porous adsorbents like zeolite. To ... En savoir plus
Hunting Lodge St. Hubertus is one of the most prominent Dutch buildings from the early twentieth century. An extensive study of wind and wind-driven rain (WDR) was conducted to provide insight into the moisture load of the building facade, using measurements and CFD simulations. COMSOL ... En savoir plus
This paper studies sound energy flows through an aperture across two coupled spaces using a diffusion equation model. The so-called double sloped sound energy decay is believed to be caused by the sound energy exchange through the aperture coupling the two rooms. The room diffusion ... En savoir plus
An attempt was made, as described in this paper, to assign material properties like shear strength and modulus of elasticity randomly. In this way, the behaviour of a masonry wall with a prefabricated concrete lintel was experimentally tested and simulated using COMSOL. The paper ... En savoir plus
The paper addresses a class of problems for modeling and consequently simulating the electromagnetic field radiation pattern from a two arm Archimedes spiral coil. The performance of particular interest is knowledge of the radiated magnetic field H and electric field E in the ... En savoir plus
Finite element analysis provides new insights into the electrical behavior of conducting adhesives. We show that at a contact between a spherical conducting particle and a flat conducting substrate the current distribution is non-uniform: the current is concentrated at the periphery of ...

Iouri Balachov is a Senior Scientist at SRI International (Menlo Park, CA) where he is leading development of Direct Carbon Fuel Cell technology for clean and efficient power generation from coal, biomass, and a wide variety of carbon containing fuels. Prior to SRI he was an engineer at ... En savoir plus
We have developed a model for computing current and field distributions in multifilamentary superconducting thin films subjected to the simultaneous effects of transport ac current and applied dc field perpendicular to the sample. The model is implemented in COMSOL’s PDE module (general ... En savoir plus
In this paper we present a new model for computing the current density and field distributions in superconductors by means of a periodic space-time formulation for finite elements (FE). By considering a space dimension as time, we can use a static model to solve a time dependent problem. ... En savoir plus
