monoatomique Modèle fluide COMSOL densité de charge température électronique Radiofrequency plasma capacitive discharge (CCP) inductive discharge (ICP) monatomic plasma Fluid model charge density electron temperature ????? ???? ?????? ?????? ?????? ?????? ???????Index. décimale : 621 Electronique Résumé : "The aim of the present work is to develop a numerical model which permits a multidimensional simulation of the distribution of the different charged particles and neutral species, potential and electric field, electronic temperature and reaction rates in radiofrequency discharges, for electropositive plasma produced in a capacitively coupled reactor (CCP) and in an inductively coupled reactor (ICP), respectively. For this, and after
applying some simplifying assumptions and boundary and initial conditions, we developed a fluid self - consistent model to describe the behaviour of various plasma parameters. The model developed is based on the resolution of the first three moments of the Boltzmann equation. These three moments, which are the continuity equation, the transfer of momentum equation and electron mean energy’s equation, are coupled to the Poisson equation and the
Maxwell equations to form a non-linear and strongly coupled system of equations. We therefore process for its resolution using Comsol Multiphysics commercial software which is based on the finite element method. The analysis of the influence of operating parameters such as pressure and RF frequency and power on the plasma characteristics is also considered in this study.

ElectroniqueTags : microplasma microréacteur volumes finis microdécharge cathode creuse Comsol microreactor finite volume microdischarge hollow cathode ??????????? ?????????? ??? ????? ???? ???? Index. décimale : 621 Electronique Résumé : The present work is to develop a single and multi-dimensional numerical model to describe the transport phenomena of charged and excited species in a cold plasma microreactor. For that, we first developed a simple fluid model using the drift and diffusion approximation containing only the ionization
process in continuous mode and simulated by the finite volume method written in FORTRAN code. Eventually we developed this model by exploiting the commercial software Comsol, for a digital micro-hollow cathode discharge study submitted to radiofrequency excitation. The two dimensional simulation
performed allowed us to do a study on the effect of control parameters, such as pressure, gaz temperature and frequency on the change in the electron density , the electron temperature , potential, and reaction rates of various chemical process.

??????? ???????Index. décimale : 621 Electronique Résumé : The PVT coupling is to combine a photovoltaic (PV) to a thermal heating system (heat sensor), such a system allows to improve the efficiency of the PV module (negative effect of decreased temperature) while extracting heat calories useful heating.
The objective of this study was to evaluate the energy performance of a new hybrid photovoltaic thermal sensor (PV/T) based on a new configuration of the absorber developed within the Unit for Applied Renewable Energy. The study is done as follows; modeling the energy performance of the hybrid prototype MATLAB in one dimension in dynamic mode.
And seen to predict the performance of the system in real conditions a digital 3D simulation with commercial software has been implemented, our choice fell on the Comsol Multiphysics software.
Model validation was performed experimentally; the simulation results are in good agreement with experimental measurements. The advantage of such a structure is the simplicity of implementation by contribution to the model of PV/T tube and energy saving improvement comparing to that in the model PV/T vessel, not to mention the lower cost resulting from the use of galvanizing steel in the manufacture of the absorber compared to copper.
A numerical approach of a second new configuration of PV/T hybrid collector was established under COMSOL to confirm the feasibility of such a design. From the simulation results, we find that this second PVT configuration can effectively reduce the temperature of the photovoltaic module and consequently improve the electrical performance.
