Transient, two-dimensional (axisymmetric) simulations of a cigarette subject to realistic static and forward smoldering cycles were performed. The computational domain consists of a porous packed bed of tobacco and a filter surrounded by a thin, porous paper and a region of surrounding ... En savoir plus
In biomedical research the use of animal models gives rise to several ethical problems. COMSOL Multiphysics® may be used as a non-animal technique, very useful in overcoming all these concerns. In this presentation a particular application in dermatology is shown. Bioheat equation ... En savoir plus
In a soil pore, water flows through the biofilm, where the density of the latter was assumed to represent a flow resistance. This mechanism was implemented as a local change of fluid viscosity proportional to local biofilm density. It was assumed that diffusive substrate transport is ... En savoir plus
COMSOL Multiphysics® software was used to simulate and analyze the transmission attenuation spectra of the negative curvature hollow-core fiber (NCHCF) over the wavelength from 2.7 μm to 4.2 μm. The effect of thickness of capillaries and the effect of the distance between the capillaries ... En savoir plus
This paper describes the numerical modeling of a key material-stability issue within the realm of Molten Carbonate Fuel Cells (MCFC). The model describes the morphological and attending electrocatalytic evolution of porous NiO electrodes and is apt to predict electrochemical observables ... En savoir plus
Metal honeycombs are used as catalyst supports. They can be considered as complex fins for heat exchange. A simple heat transfer model was compared with 2D simulations using COMSOL Multiphysics. There was a good correlation when the fluid temperature was the same in all cells. However, ... En savoir plus
The effect of the infinite length approximation on evaluating the temperature of the surface of Borehole Heat Exchangers is determined by means of COMSOL Multiphysics. In detail, two 2D models of a BHE are compared: in the first model, the domain is represented by a cross-section of the ... En savoir plus
Non-thermal plasma, generated in atmospheric pressure discharges, has been investigated in our laboratory in order to treat highly diluted (300 ppm to 1000 ppm) volatile pollutant. The collision of electrons created in the discharge with atmospheric air, leads to the formation of ... En savoir plus
This paper aims to demonstrate the simulation of photoacoustic signals using FEM software. The Acoustics Module of the software COMSOL Multiphysics is used to calculate the response of a differential Helmholtz resonator cell. In a second part a preliminary result obtained with the ...
