Bread is a food product which various complex physico-chemical phenomena occur during the cooking process. Thus, phenomena of heat and mass transfer are coupled to the deformation. In addition, bread is a multiphase product (solid, liquid and vapor) and composed of various components (dry matter, water, air and carbon dioxide). A 2D model is developed with COMSOL Multiphysics® 4.3b witch ...

A two-dimensional mathematical model for the absorption and desorption of H2 in LaNi4.8Al0.2 was developed and experimentally validated. The model is composed of an energy balance, a mass balance and a momentum balance. These differential equations are numerically solved by means of the finite element method using the software COMSOL Multiphysics®. From a comparison between theoretical ...

High temperature processes are used in a large variety of industrial application. Simulation helps to solve technological problems and increase energy efficiency in case of industrial scale simulation. We present in this paper a research equipment simulation. The aim is to increase knowledge of temperature field in the crystal growth region in order to give researcher some important information ...

The self-induced ion plating (SIIP) process is a new physical vapor deposition process based on the evaporation of a metallic target (i.e. tin) thanks to a magnetron sputtering system. The aim of this work is to develop a numerical simulation model of the SIIP process in order to predict the target temperature field and from it, the coating profile on the substrate. The simulation of the SIIP ...

Extrusion is one of the important manufacturing methods in many industries. In order to obtain the desired product quality and characteristics, the knowledge of the thermal state of the die is very important. In the present study, a two-dimensional conjugate heat transfer model has been developed for non-Newtonian materials being processed in the extrusion die. The modeling equations for the ...

In this paper, we present a mathematical model for simulating the mass transfer, during the osmotic dehydration of mango cubes. The mass balance equation for the transport of each constituent is established separately for intracellular and extracellular volumes but accounts for the mass exchange across the cell membrane and the shrinkage of whole tissue.

Metal hydrides are a widely-used method for storing and releasing hydrogen chemically under moderate conditions. This paper will present how highly dynamic metal hydride storage has been simulated and optimized using COMSOL Multiphysics. It will be shown how mass, energy and momentum balances were implemented and what boundary conditions were set to resolve various scenarios. The result of the ...

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 ...

The aim of the poster is to present a coupled 2D mathematical model to predict the evolution of drug concentration - in the cornea and in the anterior chamber of the eye - when therapeutic lenses are used (Figure 1). The mathematical model takes into account (i) diffusion processes in several compartments of the eye (therapeutic lens, cornea and anterior chamber); (ii) metabolic consuming ...

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 ...
