Aboard the International Space Station, carbon dioxide is removed from the atmosphere using a four-bed adsorptive separation process, referred to generally as a 4-Bed Molecular Sieve (4BMS). Experience with the current 4BMS design in space has led to a list of areas for improvement for a ... En savoir plus
A three-dimensional model of particle saltation using computational fluid dynamics (CFD) is presented. This model domain reproduces a flat and irregular terrain with uniform roughness. The domain extends 2 m in X, 0.5 m in Y and 0.5 in Z for both cases. The model includes the motion of ... En savoir plus
In a recent publication (Limitations of Breakthrough Curve Analysis in Fixed-Bed Adsorption, Ind. Eng. Chem. Res. 2016, 55, 4734-4748) the authors discussed the a priori prediction of the axial dispersion coefficient from available correlations versus obtaining it and also mass transfer ... En savoir plus
A finite element model for underground corrosion is presented. The model is capable of predicting regions experiencing high levels of corrosion due to differential aeration and helps identify "corrosion hotspots" where physical examination of the buried asset is not feasible. ... En savoir plus
As in industrial countries, people spend most of their time indoors and the stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality, one approach for abating indoor air pollution is the integration or retrofitting of a ...

In solution, sodium dodecyl sulfate (SDS) (structure shown in Fig. 1) can form a boundary film on metal surfaces. Previous studies have extensively investigated the characteristics of such surfactant films experimentally [1][2][3]. A dependency of SDS surface concentration and film ... En savoir plus
Marangoni flow affects the heat and mass transfer occurring in the molten metal regions in welding and additive manufacturing processes. It originates from the surface tension gradient (∂γ/∂T) induced at the melt pool surface due to the temperature difference. The flow pattern within ... En savoir plus
This paper shows the solution of mathematical model of supercritical fluid extraction process, given by Sovova H., 1994, through COMSOL Multiphysics® software. Sovova et al., 1994 used this model for the supercritical CO2 extraction of grape seed. Extraction was performed with different ... En savoir plus
In the present work, COMSOL Multiphysics® software was used to solve a mass transfer based mathematical model (Stastova et al., 1996) which is a modified form of Sovova H.,1994 model. The modification has been brought about by introducing the term ‘Grinding efficiency’ in the model and ... En savoir plus
Darcian and non-Darcian porous media are characterized by the porosity of medium. To capture miscible viscous fingering in both types of porous media, a new model built with COMSOL® software is presented by coupling of two different physics interfaces (hydrodynamics and transport of ...
