The axial injection torch (AIT) produces high-density plasmas by coupling microwave power to a flowing gas. The plasma is imposed by defining its electron density and temperature whose maximum are given by optical emission spectroscopy diagnostics. Our study of an AIT with COMSOL ... En savoir plus

A model was developed to simulate the reaction, concentration field, flow field, and temperature distribution inside a Claus reactor for converting hydrogen sulfide to sulfur. The model considered two ideal reactors, a continuous stirred tank reactor and a plug flow reactor. As expected, ... En savoir plus

The advent of Micro/Nano fluidic technologies has enabled researchers from various fields to use these advancements for analysis and experiments. In this work we present such a device that can be used for analyzing coagulation of blood in a microchannel by measuring the displacement of ... En savoir plus

In this work we tackle a more theoretical aspect of micro-injection molding, to better understand physics during the process, through numerical simulations of cavity filling. We developed a two phase flow approach by the use of COMSOL Multiphysics®. In a first step, a Level Set model is ... En savoir plus

A quantification of spatial and temporal evolution of laser-induced plume would enhance the comprehension of high speed imaging results and allow optimizing the acquisition conditions for the emission spectroscopy. What temperature and concentrations of the evaporating species are ... En savoir plus

We have simulated the ultrasound-induced acoustophoretic motion of microparticles suspended in an aqueous solution. The full first-order thermoviscous acoustics equations have been implented on a rectangular microfluidic 2D domain excited with an ultrasound field tuned to resonance near ... En savoir plus

Cake batters are complex fat-in-water emulsions with four bulk phases (aqueous, fat, gas, and solid starch granules). The process of cake baking is very complex since a change in thermo-physical properties of batter take place during this process. The aim of this project is to develop an ... En savoir plus

The heat transfer rate and borehole design represent great challenges to thermal equipment designer of the ground-coupled heat pump. The present model represents a mathematical numerical technique implemented to tackle such problem. A thermal assessment was established to estimate the ... En savoir plus

Single turn coils are used in pulsed magnetic technologies for which both magneto-harmonic and transient magnetic analysis are required. We suggest studying one single turn coil example made of a conducting massive coil, an optional conducting field shaper and an internal conducting tube ... En savoir plus

The use of an acoustic field to control the boiling process has the potential to increase the overall rate of heat transfer and delay the critical transition to film boiling. This system is being investigated through the development of a model of a single boiling bubble near a flat, ... En savoir plus
