DOWNLOAD EBOOKAdvances in Turbulence VII contains an overview of the state of turbulence research with some bias towards work done in Europe. It represents an almost complete collection of the invited and contributed papers delivered at the Seventh European Turbulence Conference, sponsored by EUROMECH and ERCOFTAC and organized by the Observatoire de la Côte d'Azur. New high-Reynolds number experiments combined with new techniques of imaging, non-intrusive probing, processing and simulation provide high-quality data which put significant constraints on possible theories. For the first time, it has been shown, for a class of passive scalar problems, why dimensional analysis sometimes gives the wrong answers and how anomalous intermittency corrections can be calculated from first principles. The volume is thus geared towards specialists in the area of flow turbulence who could not attend the conference as well as anybody interested in this rapidly moving field.

DOWNLOAD EBOOKCE MEMOIRE RELATE UN TRAVAIL CONSACRE A LA MODELISATION DE LA TURBULENCE, ETUDIEE DANS LE CADRE PARTICULIER DE LA SIMULATION D'INTERACTIONS ONDE DE CHOC-COUCHE LIMITE TURBULENTE. DANS UNE PREMIERE PARTIE, UNE REVUE DES DIFFERENTS TYPES DE MODELES EST EFFECTUEE SELON UNE HIERARCHIE ALLANT DES MODELES LES PLUS SIMPLES, BASES SUR LA DETERMINATION D'UNE LONGUEUR DE MELANGE, A DES MODELES PLUS COMPLEXES PRENANT EN COMPTE LES CARACTERES ANISOTROPE ET TRIDIMENSIONNEL DE LA TURBULENCE. LA SECONDE PARTIE DE CE MEMOIRE EST CONSACRE A LA MISE EN UVRE ET A LA VALIDATION D'UN MODELE DE TURBULENCE A DEUX EQUATIONS DE TRANSPORT (K,EPSILON) DE JONES-LAUNDER EN FORMULATION BAS NOMBRE DE REYNOLDS. ON PRESENTE L'INTEGRATION DE CE MODELE DANS UN CODE DE CALCUL TRIDIMENSIONNEL, CANARI, RESOLVANT LES EQUATIONS DE NAVIER-STOKES MOYENNEES. CE CODE DE CALCUL EST CARACTERISE PAR UNE METHODE NUMERIQUE FONDEE SUR UNE APPROCHE VOLUMES FINIS UTILISANT UN SCHEMA EXPLICITE CENTRE DE TYPE LAX-WENDROFF. UN TRAVAIL D'IMPLANTATION D'UN MODELE DU SECOND ORDRE DE TYPE ASM DONT LE CODE EST EGALEMENT CONSIDERE. LA VALIDATION EST EFFECTUEE SUR DIFFERENTS CAS EXPERIMENTES D'ECOULEMENTS INTERNES TRANSSONIQUES. ON PRESENTE UNE ANALYSE PARTICULIEREMENT DETAILLEE D'UN CAS D'INTERACTION ONDE DE CHOC-COUCHE LIMITE FORTEMENT TRIDIMENSIONNELLE POUR LAQUELLE ON DISPOSE DE NOMBREUSES DONNEES EXPERIMENTALES POUR LE CHAMP MOYEN ET LE CHAMP TURBULENT. LES RESULTATS OBTENUS AVEC LE MODELE (K,EPSILON) SONT EGALEMENT COMPARES AVEC CEUX OBTENUS EN UTILISANT UN MODELE DE LONGUEUR DE MELANGE INITIALEMENT DEVELOPPE DANS LE CODE. CES COMPARAISONS METTENT EN EVIDENCE LA NETTE AMELIORATION APPORTEE PAR L'UTILISATION DU MODELE (K,EPSILON), NOTAMMENT DANS LES REGIONS OU L'ECOULEMENT EST FORTEMENT DECOLLE

DOWNLOAD EBOOKThis 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.).
