The rate of liquid copper oxidation plays an important role in the separation of impurities from copper during fire refining. A finite elements numerical model using FEMLAB 3.1 for the oxidation of liquid copper during top blowing of oxygen/nitrogen mixtures is presented and compared to experimental results. In this model, surface tension driven flow arising from gradients of oxygen ...

The subject of this investigation is a recently developed Electric Swing Adsorption (ESA) system (adsorption cycle with electrothermal desorption step, which is performed by direct heating of the adsorbent particles by passing electric current through them), with an adsorber assembled of two annular, radial-flow, cartridge-type fixed-beds, with in-vessel condensation. Three FEMLAB models were ...

The thermoplastics injection-molding process of has become one of the most important polymer processing operations in the production of molded parts with geometric complexity and high precision. Modeling and computer simulation of this process is not an easy task. Commercial computer packages have been designed for the simulation of the injection molding process. These programs allow the ...

A lixiviation-mechanical coupled model is developed for fiber reinforced concrete within this framework; both the influence of chemical degradation on short and long term mechanical behavior and the influence of mechanical loading on the diffusion coefficient can be considered. The elastic mechanical properties are written as function of chemical damage. A Drucker–Prager typed criterion with ...

Drying of biomaterials such as foodstuffs involves mass, momentum and energy transport along with large shrinkage of the porous material, which have significant effects on their final quality. Foodstuffs exhibit non-linearity when undergoing large deformations that affect the transport process in a critical way. Thus, it becomes important to perform a two-way coupling of the multiphase transport ...

Tissue engineering (TE) is a multidisciplinary field involving principles of engineering and life sciences to improve the health and quality of life by repairing, restoring, maintaining, or enhancing tissue and organ function using cells, scaffolds, and growth factors alone or in combination. There are several artificial tissues that are already being used which include fabricated skin, ...

Targeted drug delivery systems have been wildly studied in cancer therapy due to the toxicity of most of chemotherapeutic drugs. Nanoparticles can be attached to the small molecules of the drugs and serve as drug carriers to deliver the drug molecules into the area of interest. In this research, polymeric microspheres containing biodegradable poly(D, L-lactide-co-glycolide) (PLGA), magnetic ...

This work demonstrated the importance and feasibility of experimental image to simulation workflow. The workflow is successfully applied to a food processing study, where multiphysics and multiscale modeling based on 3D experimental image reconstruction contributes to the preservation of corn, one of the major food sources for the world population.

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 the degradation of methyl red by a Glidarc humid air plasma producing active species, mainly OH, that can ...
