Book excerpt: LES ETUDES SUR LES JETS PARIETAUX PEUVENT ETRE CLASSES EN GROS, EN DEUX GROUPES. L'UN CONCERNANT CELLES RELATIVES A L'ETUDE CINEMATIQUE DE L'ECOULEMENT DANS LA ZONE DITE DE REGIME ETABLI, ET LE SECOND CONCERNE CELLES RELATIVES AUX ASPECTS THERMIQUES DU PROBLEME. LE PRESENT TRAVAIL S'INSCRIT AU SEIN DU PREMIER GROUPE D'ETUDES. IL PRESENTE DE MULTIPLES ASPECTS RELATIFS AU JET PARIETAL ET QUI INTERFERENT LES UNS AVEC LES AUTRES. DANS UNE ETUDE BIBLIOGRAPHIQUE APPROFONDIE DU JET PARIETAL (CHAPITRE 1), NOUS AVONS PRESENTE UN ENSEMBLE DE DONNEES THEORIQUES ET EXPERIMENTALES PROVENANT DE LA LITTERATURE. LES RESULTATS PROVENANT DES THEORIES ET SURTOUT LES FORMULES SEMI-EMPIRIQUES SONT COMPAREES LES UNES AUX AUTRES AINSI QU'AUX EXPERIENCES. LA SECONDE PARTIE (CHAPITRE 2) CONSISTE EN UNE ETUDE THEORIQUE D'UN JET PARIETAL, PLAN LAMINAIRE ET A BASSES VITESSES, DELIVRE PAR UNE SOUFFLERIE SUBSONIQUE. CETTE ETUDE THEORIQUE EST BASEE SUR LES EQUATIONS DE NAVIER-STOKES ET LA THEORIE, DUE A GLAUERT ET QUI UTILISE LE CARACTERE AUTO-SEMBLABLE DE L'ECOULEMENT. L'ENSEMBLE DES GRANDEURS GLOBALES CARACTERISTIQUES DU JET PARIETAL EN DECOULENT SOUS FORMES ANALYTIQUES, EXPLICITES. EN EFFET, POUR NOUS APPROCHER DU MIEUX DE LA REALITE DE L'ECOULEMENT, NOUS INTRODUISONS SYSTEMATIQUEMENT L'ORIGINE VIRTUELLE DU JET PARIETAL ET UNE REPARTITION DE VITESSE PARABOLIQUE A LA SORTIE DU JET. AINSI, NOUS AVONS PU AFFINER LES RESULTATS DES CALCULS ET LES RENDRE PLUS PROCHES DES DONNEES FOURNIES PAR LES MESURES. LE TROISIEME CHAPITRE A POUR OBJET LA DESCRIPTION DU DISPOSITIF EXPERIMENTAL, DE LA CHAINE D'APPAREILLAGES AINSI QUE LES PROCEDURES DE MESURES UTILISEES. DANS LE QUATRIEME CHAPITRE SONT PRESENTES LES RESULTATS EXPERIMENTAUX, AVEC CONFRONTATION AUX RESULTATS ANALYTIQUES CONNUS OU ETABLIS AU DEUXIEME CHAPITRE. DIVERS POINTS Y SONT TRAITES, DONT LES PRINCIPAUX SONT: 1) PROFILS DE VITESSE ET TAUX DE TURBULENCE ENTRAINEMENT DU JET: DEBIT VOLUMIQUE ET QUANTITE DE MOUVEMENT COMPARAISON DE LA REGION INTERNE DU JET AVEC UNE COUCHE LIMITE CLASSIQUE DE BLASIUS; 2) MISE EN EVIDENCE DE DIFFERENTES SOUS-COUCHES DANS LA REGION TURBULENTE DE PAROI DU JET; 3) ZONE DE VALIDITE DE LOI LOGARITHMIQUE CLASSIQUE EN REGION INTERNE DU JET PARIETAL LOI EMPIRIQUE POUR LE COEFFICIENT DE FROTTEMENT PARIETAL INFLUENCE DE RUGOSITES SPHERIQUES, REGULIEREMENT DISPOSEES SUR LA PLAQUE, SUR LE CHAMPS DE VITESSE ET SUR LA TURBULENCE EN REGION INTERNE DU JET PARIETAL. LA SIMILITUDE DU JET LIBRE N'ETANT PAS APPLICABLE A L'ENSEMBLE DU JET PARIETAL (GLAUERT), POUR NOTRE PART, DANS LA REGION DU JET OU LE REGIME D'ECOULEMENT EST ETABLI ET TURBULENT, NOUS NOUS SOMMES LIMITES A DES EXPERIENCES DONT NOUS CONFRONTONS LES RESULTATS AUX THEORIES TURBULENTES DU JET PARIETAL; PAR AILLEURS, NOUS AVONS TENTE DES APPROCHES NUMERIQUES DE CES RESULTATS EXPERIMENTAUX, NOTAMMENT EN CE QUI CONCERNE LA REGION EXTERNE DU JET. DES LOIS EMPIRIQUES DU TYPE FORMULATION D'UN JET LIBRE SONT DONNEES POUR CETTE REGION

Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of the world renowned ERCOFTAC (International Symposium on Engineering Turbulence Modelling and Measurements).The proceedings include papers dealing with the following areas of turbulence:·Eddy-viscosity and second-order RANS models ·Direct and large-eddy simulations and deductions for conventional modelling ·Measurement and visualization techniques, experimental studies ·Turbulence control ·Transition and effects of curvature, rotation and buoyancy on turbulence ·Aero-acoustics ·Heat and mass transfer and chemically reacting flows ·Compressible flows, shock phenomena ·Two-phase flows ·Applications in aerospace engineering, turbomachinery and reciprocating engines, industrial aerodynamics and wind engineering, and selected chemical engineering problems Turbulence remains one of the key issues in tackling engineering flow problems. These problems are solved more and more by CFD analysis, the reliability of which depends strongly on the performance of the turbulence models employed. Successful simulation of turbulence requires the understanding of the complex physical phenomena involved and suitable models for describing the turbulent momentum, heat and mass transfer. For the understanding of turbulence phenomena, experiments are indispensable, but they are equally important for providing data for the development and testing of turbulence models and hence for CFD software validation. As in other fields of Science, in the rapidly developing discipline of turbulence, swift progress can be achieved only by keeping up to date with recent advances all over the world and by exchanging ideas with colleagues active in related fields.

Available in PDF, EPUB and Kindle. Book excerpt: The present book contains papers that have been selected from contributions to the First International Symposium on Turbulent Shear Flows which was held from the 18th to 20th April 1977 at The Pennsylvania State University, University Park, Pennsylvania, USA. Attend ees from close to 20 countries presented over 100 contributions at this meeting in which many aspects of the current activities in turbulence research were covered. Five topics received particular attention at the Symposium: Free Flows Wall Flows Recirculating Flows Developments in Reynolds Stress Closures New Directions in Modeling This is also reflected in the five chapters of this book with contributions from research workers from different countries. Each chapter covers the most valuable contributions of the conference to the particular chapter topic. Of course, there were many additional good con tributions to each subject at the meeting but the limitation imposed on the length of this volume required that a selection be made. The realization of the First International Symposium on Turbulent Shear Flows was p- sible by the general support of: U. S. Army Research Office U. S. Navy Research Office Continuing Education Center of The Pennsylvania State University The conference organization was carried out by the organizing committee consisting of: F. Durst, Universitat Karlsruhe, Karlsruhe, Fed. Rep. of Germany V. W. Goldschmidt, Purdue University, West Lafayette, Ind. , USA B. E. Launder, University of California, Davis, Calif. , USA F. W.
