In this work, a COMSOL model that predicts velocity and concentration fields inside an X-shaped millichannel (4 mm diameter) is developed. Water and a ink low concentration are injected simultaneously in the two inlets of the device. The mass transfer problem is solved by a Fickian model (solute concentration is low compared with the solvent). The parameters in this study are: initial inlet mass ...

The computer simulation with COMSOL Multiphysics has become a widely used technique for the study of various problems in the field of plasma physics. Despite the increasing performance of computers, fully three-dimensional particle simulations still have got extremely high demands on hardware and computer time. Although many problems could be solved by fluid models, results obtained by these ...

Analysis and optimization of air flow distribution inside drying kiln systems contribute to the improvement of the final product quality. The present study reports on the threedimensional numerical solution of air flow within a drying kiln enclosure. The air flow field is examined in different configurations and operation conditions. Depending on the off/on switched fans, we obtain various air ...

A lot of techniques are developed to treat soils polluted by hydrocarbons pollutants: incineration, thermal treatment, extraction, chemical oxidation, bioremediation… Some of these techniques are very energy consuming (incineration, thermal treatment…) and often need a subsequent treatment of the generated gases or liquids. Of all the decontamination methods, bioremediation appears to be the ...

This paper will give a short overview of use of COMSOL Multiphysics for analyzing ancient Greek and Roman catapults with the main focus on the energy storing torsion springs. Catapults have been known and used in the Greek and Roman world from around 399 BC and a fully standardized design for powerful torsion catapults emerged around 270 BC, based on one basic factor, the diameter of the torsion ...
