This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'impact négatif de l'automobile sur l'environnement a entraîné une sévérisation des normes législatives pour protéger celui-ci. Les difficultés rencontrées lors de l'amélioration du rendement du moteur à allumage commandé, résultent principalement de son fonctionnement inefficace à charges partielles. La distribution variable est capable d'améliorations concernant la réduction de la consommation de carburant, surtout dans une zone d'utilisation fréquente : basses charges et bas régimes. Une alternative à l'étude expérimentale est l'approche par simulation numérique, CFD en utilisant le logiciel ANSYS-Fluent. Dans cette thèse de doctorat, le but principal a été de déterminer les vitesses d'écoulement du fluide pendant le processus d'admission pour deux lois de levée de la soupape, pour un moteur entraîné à 815 tr/min et une ouverture du papillon de gaz de 21.6°. Dans ce but, on a utilisé deux modèles de simulation numérique: un modèle bidimensionnel et un modèle tridimensionnel. L'étude réalisée par simulation numérique a permis de clarifier quelques aspects importants concernant les vitesses d'écoulement de l'air dans le cylindre et le degré de turbulence.

Book excerpt: L'ETUDE DES ECOULEMENTS PULSES A L'ECHAPPEMENT D'UN MOTEUR A COMBUSTION INTERNE EST AXEE PRINCIPALEMENT SUR LA CONNAISSANCE DES PARAMETRES PHYSIQUES DU FLUIDE. LA METHODE DES VOLUMES FINIS UTILISES POUR LA SIMULATION DES ECOULEMENTS PULSES EST BASEE SUR LE SCHEMA AUX DIFFERENCES DE GODOUNOV. NOUS AVONS TESTE LA CAPACITE DU MODELE POUR DEUX TYPES D'ECOULEMENT, A TRAVERS UN TUBE DROIT ET SURTOUT DANS UNE JONCTION. LES SIMULATIONS REALISEES POUR DIFFERENTS REGIMES ET CHARGES D'UN MOTEUR ONT PERMIS DE DEMONTRER QUE L'EMPLOI D'UNE TELLE METHODE NUMERIQUE DECRIVAIT D'UNE FACON TRES SATISFAISANTE LE PHENOMENE PHYSIQUE OBSERVE; POUR L'ECOULEMENT BIDIMENSIONNEL, LES RESULTATS OBTENUS SONT TRES SATISFAISANTS. L'UTILISATION DES TERMES DE FROTTEMENT DANS LES EQUATIONS NOUS MONTRENT QU'ILS SONT DES TERMES CORRECTIFS QUI APPARAISSENT NETTEMENT AVEC L'AUGMENTATION DE LA VITESSE D'ECOULEMENT

Book excerpt: "The Ladybird is a long tale or novella by D. H. Lawrence. It was first drafted in 1915 as a short story entitled The Thimble. Lawrence rewrote and extended it under a new title in December 1921 and sent the final version to his English agent on 9 January 1922. It was collected with two other tales, The Captain's Doll and The Fox, and the three novellas were then published in London by Martin Secker in March 1923 under the title The Ladybird and in New York by Thomas Seltzer as The Captain's Doll in April 1923."

This book was released on 2011-12-15 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Yearbook of European Legal Studies provides a forum for the scrutiny of significant issues in EU Law, the law of the European Convention on Human Rights, and Comparative Law with a 'European' dimension, and particularly those issues which have come to the fore during the year preceding publication. The contributions appearing in the collection are commissioned by the Centre for European Legal Studies (CELS) Cambridge, a research centre in the Law Faculty of the University of Cambridge specialising in European legal issues. The papers presented are at the cutting edge of the fields which they address, and reflect the views of recognised experts drawn from the University world, legal practice, and the institutions of both the EU and its Member States. Inclusion of the comparative dimension brings a fresh perspective to the study of European law, and highlights the effects of globalisation of the law more generally, and the resulting cross fertilisation of norms and ideas that has occurred among previously sovereign and separate legal orders. The Cambridge Yearbook of European Legal Studies is an invaluable resource for those wishing to keep pace with legal developments in the fast moving world of European integration.
