Book Description
Cette thèse traite des phénomènes de propagation des ondes de pression dans les systèmes d'admission et d'échappement des moteurs à combustion interne. Ces derniers sont constitués d'éléments tubulaires reliés entre eux par différents type de singularités (coude, jonction, collecteur, boîtier papillon,) qui affectent la forme des ondes engendrées par l'ouverture et la fermeture des soupapes. La démarche mise en œuvre pour comprendre et analyser les phénomènes observés consiste à améliorer le logiciel SELENDIA (développé au laboratoire) simulant le fonctionnement d'un moteur complet. L'objectif est de remplacer la méthode de vidange remplissage pour les systèmes d'admission et d'échappement par une modélisation unidimensionnelle. La première étape repose sur la détermination du schéma numérique le mieux adapté à la résolution des équations de la dynamique des gaz. Puis, chacune des singularités est caractérisée par une étude au moyen d'un code de calcul CFD accompagnée d'une validation expérimentale sur un tube à chocs. L'ensemble des modèles développés est ensuite intégré au sein du logiciel de simulation du fonctionnement des moteurs. La validation de toute la procédure est finalement réalisée par comparaison avec des mesures effectuées sur un moteur test, instrumenté spécifiquement pour cette étude. Le logiciel ainsi obtenu se présente comme un moyen d'analyse des phénomènes observés au banc d'essais, mais aussi d'assistance à la conception et à l'optimisation des moteurs à combustion interne.

Book Description
This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.

Book Description
This didactic book presents the main elements of acoustics, aeroacoustics and vibrations. Illustrated with numerous concrete examples linked to solid and fluid continua, Acoustics, Aeroacoustics and Vibrations proposes a selection of applications encountered in the three fields, whether in room acoustics, transport, energy production systems or environmental problems. Theoretical approaches enable us to analyze the different processes in play. Typical results, mostly from numerical simulations, are used to illustrate the main phenomena (fluid acoustics, radiation, diffraction, vibroacoustics, etc.).
