Pore-level displacement of heavy-oil during thermal operations such as SAGD and CSS is a complex multi-scale phenomenon. As gravity drainage is the main depletion mechanism within the intergranular pore space, the surface tension-related phenomena are dominant in intra-granular micro ... En savoir plus
The use of plasmas for the treatment industrial effluents provides a new alternative to the decontamination of wastewater. The strong oxidizing species (O,O3, OH) generated by the plasma, at room temperature, can oxidise organic pollutants present in the water. Our simulation deals with ... En savoir plus
The conventional route to hydrogen production is by steam reforming of methane (MSR) in a multitubular packed bed. With the increasing use of biodiesel as a renewable fuel, interest has grown in steam reforming of the excess glycerol produced as a side product (GSR). We use COMSOL ... En savoir plus
The present study deals with a twodimensional modeling and simulation of a thermal swing adsorption (TSA) process used for the capture of CO2 from CO2/N2 mixture. The models are described by partial differential equations (PDEs) including conservation equations, models for equation of ... En savoir plus
Electric resistances are widely used as heating elements in domestic and industrial equipment; since process water contains calcium carbonate and calcium bicarbonate, limescale plays an important role on global efficiency of water-heating systems. Calcium carbonate has a very low thermal ... En savoir plus
In this paper a new method for turbulent combustion modeling is introduced in COMSOL Multiphysics®. The method is called Flamelet Generated Manifolds (FGM). The method is based on the concept of flamelets, elemental reaction layers in combustion. The only hypothesis is that the turbulent ... En savoir plus
The geomechanical effects related to CO2 injection into the Krechba formation at In Salah, Algeria, are considered through a coupled modeling approach to simulate simultaneously CO2 migration in the aquifer and the surrounding formations, as well as the poro-elastic stress changes ...

Proper storage of grains depends on minimizing attacks of insects, fungi, mites, etc. Development of such pests can be controlled by controlling the temperature of the storage chamber. Hence, before designing grain storage chambers, mathematical modeling and numerical simulations should ... En savoir plus
Introduction: This work presents the design of a novel flow cell based miniaturized electrochemical respirometer to monitor organic content in water samples semi-continuously, in contrast to current Biochemical Oxygen Demand, BOD, methods. Simulation techniques has been used to ... En savoir plus
A finite element model of a polymer electrolyte membrane fuel cell (PEMFC) is described in this paper. We divide the PEMFC into two separate and parallel 2D regions which are connected by the 1D regions representing the membrane electrode assembly (MEA). COMSOL Multiphysics® was used as ...
