Book excerpt: L'UN DES FACTEURS LIE AU DECLENCHEMENT DE LA TURBULENCE EN CIEL CLAIR EST UN CISAILLEMENT IMPORTANT DU A DES FORTS GRADIENTS VERTICAUX DE VENT DANS UN FLUIDE STABLE. LE BUT PRINCIPAL ETAIT D'ETUDIER SUR UN MODELE DE LABORATOIRE, DES CONDITIONS DE DECLENCHEMENT DE LA TURBULENCE DANS LES ECOULEMENTS LIBRES STRATIFIES ET D'ESSAYER DE TROUVER DES CORRELATIONS SEMI-EMPIRIQUES ENTRE LES CONDITIONS INITIALES DONNANT NAISSANCE A LA TURBULENCE ET LES CARACTERISTIQUES DE CELLE-CI. COMME PREMIERE ETAPE, LE BUT A ETE L'ETUDE STRICTEMENT DYNAMIQUE (SANS STRATIFICATION THERMIQUE) DES CONDITIONS DE DECLENCHEMENT ET DE LA STRUCTURE D'UN ECOULEMENT TURBULENT, QUASI-BIDIMENSIONNEL, ETABLI DANS UN CANAL, CREE PAR DES PERTES DE CHARGES A L'ENTREE. POUR LA CREATION DE CES DERNIERES ET LA REALISATION DES PROFILS DES V, ON A UTILISE PLUSIEURS DISTRIBUTIONS GEOMETRIQUES DE GRILLAGE A MAILLES FINES, ET ON S'EST PLACE A LA SORTIE D'UN JET LIBRE SE DEVELOPPANT DANS UN CANAL BIDIMENSIONNEL. INTERPRETATION ET SYNTHESE DES RESULTATS.

Available in PDF, EPUB and Kindle. Book excerpt: Turbulence is a dangerous topic which is often at the origin of serious fights in the scientific meetings devoted to it since it represents extremely different points of view, all of which have in common their complexity, as well as an inability to solve the problem. It is even difficult to agree on what exactly is the problem to be solved. Extremely schematically, two opposing points of view have been advocated during these last ten years: the first one is "statistical", and tries to model the evolution of averaged quantities of the flow. This com has followed the glorious trail of Taylor and Kolmogorov, munity, which believes in the phenomenology of cascades, and strongly disputes the possibility of any coherence or order associated to turbulence. On the other bank of the river stands the "coherence among chaos" community, which considers turbulence from a purely deterministic po int of view, by studying either the behaviour of dynamical systems, or the stability of flows in various situations. To this community are also associated the experimentalists who seek to identify coherent structures in shear flows.

This book was released on 2012-12-06 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The General Assembly of the International Union of Theoretical and Applied Mechanics in its meeting on August 28, 1994, selected for 1996 only four Mechanics Symposia, of which ours is the only one related to Fluid Mechanics: Variable Density Low Speed Turbulent Flows. This IUTAM Symposium, organized by the Institut de Recherche sur les Phenomenes Hors Equilibre (Marseille), is the logical continuation of the meetings previously organized or co-organized - on the French or European level, such as Euromech 237, Marseille, 1988 - by the same research group ofMarseille. This meeting focused specifically on the structure of turbulent flows in which density varies strongly : the effect of this variation on the velocity and scalar fields is in no sense negligible. We were mainly concerned with low-speed flows subjected to strong local changes of density as a consequence of heat or mass transfer or of chemical reactions. Compressible turbulent flows - such a!" supersonic ones - were also considered in order to underline their similarities to and their differences from low-speed variable density flows.
