Der volle Inhalt der Quellemathématique du transport d'électrons confinés dans une nanostructure
dans le but d'implémenter des simulations numériques. Dans de tels
dispositifs nanométriques, les ordres de grandeurs ne jouent pas le
même rôle dans chaque direction. Les électrons peuvent être
extrêmement confinés dans une ou plusieurs directions. Un modèle
quantique est nécessaire pour décrire le confinement. Dans la
direction non confinée, le transport est supposé de nature classique.
Nous proposons alors un système couplé quantique/classique.
Les collisions intervenant lors du transport induisent un régime
diffusif des porteurs de charges. Le modèle diffusif est obtenu grâce
à une limite de diffusion d'un modèle cinétique. L'analyse
mathématique de cette limite de diffusion et du modèle diffusif couplé
sont présentées. Une simulation numérique du transport dans un
nanotransistor est obtenue avec ce modèle.

Der volle Inhalt der QuelleIn their common uses as electrical insulators, organic solid materials are constitutive of electric power transmission cables, power control and conversion circuits as well as (micro) electronic components or embedded systems (thermal coating of satellites, batteries of accumulators, etc.). Under various constraints of use (electric field, radiation, temperature, humidity ...) they can accumulate charges in their bulk which could affect the reliability of the systems in which they are employed. One of the commonly used means to study the electrical behavior of these charges is to measure the spatiotemporal distribution of charges by subjecting the dielectrics to a continuous potential difference between two electrodes. However, this method does not always allow clearly distinguishing the contribution of charges due to generation on the one hand and the one due to transport phenomena on the other hand. This study proposes an alternative approach, consisting in generating charges (electrons) within the electrical insulation using an electron-beam under vacuum. The charges are hence deposited at a known position and in a controlled quantity. Other physical processes related to the implantation of electrons must then be taken into account in order to predict and model the behavior of these irradiated materials. Low-density polyethylene (LDPE) films, prepared by thermal molding, were irradiated by a 80 keV electron-beam with a current flux of 1 nA/cm2. Space charge measurements using the Pulsed Electro-Acoustic (PEA) method, performed first in-situ and then ex-situ under DC electrical polarization, confirm an effective localization of charges within the material. The results under electrical polarization after irradiation show an important amount of positive charges in the irradiated zone of the dielectric. The electrical characterizations of irradiated LDPE films show a completely different behavior compared to the same non-irradiated material, suggesting a modification of the chemical structure of the material. Physico-chemical measurements (infrared spectroscopy, Photoluminescence and Differential Scanning Calorimetry-DSC) on these irradiated PEbd films do not show a significant degradation of the chemical structure of the dielectric which would explain the observed electrical behavior under post-irradiation polarization. Additional measurements show the reversible behavior of the irradiated then polarized PEbd, which would be only related to the presence of the charges generated by the beam. The experimental data of this study have simultaneously fed a numerical model of charge transport, developed to take into account the irradiation constraints. This model allows reproducing the in-situ results of charge implantation by the electron beam as well as the majority of the electrical processes observed on irradiated and polarized LDPE. It confirms the impact of the electron-beam deposited charge on the behavior under polarization and allows concluding on the origin of the positive charges observed after irradiation, which would be due to injection at the electrodes as well as to the creation of electron-hole pairs by the electron-beam during irradiation

Der volle Inhalt der QuelleReducing CO2 and pollutant emission is the essential challenge when dealing with climate change problems. In the transport sector, exhaust gas recirculation (EGR) technology is often used in turbocharged gasoline spark ignition (SI) engines to increase fuel economy, inhibit knock tendency, and reduce NOx emissions. However, high EGR ratios are still difficult to achieve, as they result in reduced heat release and engine stability. As increasing turbulence level and advance spark ignition systems could not bring sufficient improvements at such extreme conditions, growing interest is cast onto the combustion chemistry under high dilution. The present work aims to understand the combustion chemistry of highly-diluted gasoline premixed flames and to establish a detailed kinetic mechanism by multi-scale modeling to predict combustion characteristics with sufficient accuracy at highly-diluted conditions.This work adopts a multi-scale modeling approach, and targets on the laminar flame speed (SL) of a gasoline surrogate, which is named toluene reference fuel with ethanol addition (TRFE) and consist of isooctane, n-heptane, toluene, and ethanol. For micro-scale modeling, the reaction between ketene and hydroxyl radical, which might be important to the SL at highly-diluted conditions, is studied theoretically using ab initio electronic structure methods for the potential energy surface (PES) and Rice–Ramsperger–Kassel–Marcus Theory coupled with Master Equation (RRKM/ME) for the rate coefficients. Detailed PES is obtained, dominant pathways are identified, and their phenomenological rate coefficients are derived to be utilized in combustion modeling. For macro-scale modeling, firstly, important kinetic, thermodynamic, and transport parameters to the laminar flame speed at highly-diluted conditions, are firstly identified using sensitivity analysis based on a starting mechanism. Sensitive reactions are found to mostly involve HO2, C2--C3 species and fuel radicals. Secondly, in the sub-mechanisms where these reactions lies, diluted flames of the corresponding fuels are studied and chemical detail of the dilution effects are explored. The starting mechanism is updated by state-of-the-art kinetics parameters found in the literature for each sub-mechanisms. Finally, a detailed mechanism suitable for laminar flame speed calculations at highly-diluted conditions is established after validation. A mathematical SL correlation is generated for the use in computational fluid dynamic (CFD) simulations

Der volle Inhalt der QuelleThis theoretical and experimental study aims to determine the effect of various parameters - heat transfer rate, fill charge, tilt angle, operating temperature - on the global thermal resistance of a two-phase closed thermosyphon. The experimental set-up is made of a cylindrical copper tube, filled with R-113. The heat flux supplied to the evaporator section vanes between 0 and 10 W/cm2. The condenser section is cooled by a forced convective water flow. The performances are better. For high operating temperatures and, at a fixed temperature, the global thermal resistance exhibits an optimum value as the heat transfer rate increases An optimum tilt angle was found. A thermosyphon model was developed. The condenser section is divided into elliptical sub volumes, corresponding to the intersection of the tilted tube with vertical planes. The local heat transfer coefficient is calculated using the Nüsselt theory, modified to take into account the elliptical geometry and the way film flow. The heat transfer coefficient of the evaporator is calculated using various correlations from the literature. A comparison between the theoretical experimental results was carried out. Although the model does not well predict the transition from the laminar to the turbulent flow of the condensate film, the heat transfer rate and the global thermal resistance predicted by the model are m good agreement with the experimental results

Der volle Inhalt der QuelleTo react to the continual changes in the energetic demand, it is necessary to convert petroleum residues into high value fractions. To upgrade the heaviest part of the crude oil the removal of impurities, as sulfur or metals, is a necessary step. Residue hydrotreatment in fixed bed, under high hydrogen pressure achieves high removal performances, with a industrial catalysts optimized staging. This work presents an insight on different geographical origin residues reactivities. A hydrotreatment kinetic model was developed attemping to simulate the different residues performances. Despite the recent improvements, residues remain very difficult to describe and characterize in details. The comparison of different residues rea ctivities has shown a specific behaviour for each residue. One of the key reactivity parameters seems to be the residues molecules size. Small size residues react easier because more molecules access the catalytic sites. The developed model shows the interest of considering diffusion and steric hindrance inside the catalysts and the importance of a residue description in fractions allowing to consider a complex kinetic network. Finally, this new model is able to take into differences in terms of residues characteristics and then leads to fairly good simulations of residues performances
