Book excerpt: Les écoulements avec réactions chimiques peuvent intervenir dans des domaines variés tels que la combustion, le génie des procédés, l’aéronautique, l’environnement atmosphérique et aquatique. Les exemples d’application choisis dans ce volume portent principalement sur les mélanges réactifs homogènes susceptibles d’intervenir dans les propulseurs, en génie des procédés et en combustion : - propagation du son et écoulements monodimensionnels non diffusifs dans les tuyères pouvant comporter des déséquilibres des modes internes d’énergie des molécules ; - réacteurs chimiques idéaux, stabilisation de leurs points de fonctionnement stationnaires dans le cas homogène à mélange parfait et instruments classiques d’analyse expérimentale et théorique tels les bilans de population, la distribution des temps de séjour et celle des âges ; - flammes laminaires et turbulentes en séparant bien celles qui sont prémélangées de celles qui ne le sont pas et qui ne relèvent pas des mêmes mécanismes, mais qui interviennent conjointement dans le cas des flammes triples. Écoulements et réactions chimiques 2 apporte également des précisions sur l’analyse dimensionnelle, la thermodynamique statistique avec couplage entre modes internes d’énergie et réactions chimiques, l’apparition et la dissipation de la turbulence fluide ainsi que son traitement statistique, les bifurcations, les flammes en milieu confiné et de diffusion.

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.).

Available in PDF, EPUB and Kindle. Book excerpt: Le passage du bidimensionnel au tridimensionnel exige une remise en question de plusieurs notions (points de décollement et de recollement, bulbe de décollement, zone de recirculation, ligne de courant limite…) dont l’emploi en trois dimensions est inadéquat, voire dangereux. La théorie des singularités des systèmes d’équations différentielles de Poincaré permet l’introduction de concepts tels que les points singuliers, les lignes de séparation (ou d’attachement), les surfaces de séparation (ou d’attachement) et de règles topologiques qui permettent une description cohérente des écoulements tridimensionnels. Le décollement peut ainsi être défini de façon précise et le mécanisme de formation des tourbillons, du type trombe ou en fer à cheval, décrit rationnellement. Ces notions forment une grammaire qui est appliquée à la description d’écoulements décollés typiques se formant sur des ailes, sur des fuselages, devant des obstacles, derrière un arrière-corps ou autour d’un véhicule automobile. Le bidimensionnel est reconsidéré à la lumière des concepts du tridimensionnel, ce qui montre son caractère exceptionnel.

Available in PDF, EPUB and Kindle. Book excerpt: The first part aims at providing the physical and theoretical framework of the analysis of density variations in fully turbulent flows. Its scope is deliberately educational. In the second part, basic data on dynamical and scalar properties of variable density turbulent flows are presented and discussed, based on experimental data and/or results from direct numerical simulations. This part is rather concerned with a research audience. The last part is more directly devoted to an engineering audience and deals with prediction methods for turbulent flows of variable density fluid. Both first and second order, single point modeling are discussed, with special emphasis on the capability to include specific variable density / compressibility effects.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The Second European Turbulence Conference was held at the Technische Univer sitat Berlin, Federal Republic of Germany, from August 30th to September 2nd 1988 under the auspices of the European Mechanics Committee. It was primar ily devoted to fundamental aspects of turbulence, and aimed at bringing together engineers, physicists, and mathematicians. The scientific committee - serving also as Sub-committee of the European Turbulence Conference - consisted of the following members: G. Comte-Bellot (Lyon), H.-H. Fernholz and H.E. Fiedler (both from Berlin) as co-chairmen of the conference, U. Frisch (Nice), J.C.R. Hunt (Cambridge), E. Krause (Aachen), M. Landahl (Stockholm), A.M. Obukhov (Moscow), and G. Ooms (Amsterdam). The conference programme comprised 6 invited lectures and 94 contributions, presented either orally or at poster sessions. There were 165 participants from 18 countries. All papers published in these conference proceedings were, with the exception of the invited ones, again refereed by the members of the scientific committee. The main research topics discussed at this meeting were stability and gener ation of turbulence, effects of rotation, stratification and buoyancy forces, novel instrumentation, manipulation and control, boundary layers with separation and reattachment, computer simulation, turbulent diffusion, image analysis and flow visualization, vorticity dynamics and turbulence, and large-scale structures. We have taken the liberty of regrouping some papers following the submitted final versions for this volume. Authors may therefore find their paper under a different heading from that in the conference programme.

Book excerpt: for the fluctuations around the means but rather fluctuations, and appearing in the following incompressible system of equations: on any wall; at initial time, and are assumed known. This contribution arose from discussion with J. P. Guiraud on attempts to push forward our last co-signed paper (1986) and the main idea is to put a stochastic structure on fluctuations and to identify the large eddies with a part of the probability space. The Reynolds stresses are derived from a kind of Monte-Carlo process on equations for fluctuations. Those are themselves modelled against a technique, using the Guiraud and Zeytounian (1986). The scheme consists in a set of like equations, considered as random, because they mimic the large eddy fluctuations. The Reynolds stresses are got from stochastic averaging over a family of their solutions. Asymptotics underlies the scheme, but in a rather loose hidden way. We explain this in relation with homogenizati- localization processes (described within the §3. 4 ofChapter 3). Ofcourse the mathematical well posedness of the scheme is not known and the numerics would be formidable! Whether this attempt will inspire researchers in the field of highly complex turbulent flows is not foreseeable and we have hope that the idea will prove useful.

This book was released on 2013-10-08 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flows with chemical reactions can occur in various fields such as combustion, process engineering, aeronautics, the atmospheric environment and aquatics. The examples of application chosen in this book mainly concern homogeneous reactive mixtures that can occur in propellers within the fields of process engineering and combustion: – propagation of sound and monodimensional flows in nozzles, which may include disequilibria of the internal modes of the energy of molecules; – ideal chemical reactors, stabilization of their steady operation points in the homogeneous case of a perfect mixture and classical instruments of experimental and theoretical analysis such as population balances, and the distribution of residence and passage times; – laminar and turbulent flames, separating those which are premixed from those which are not and which do not exhibit the same mechanisms, but which also occur in the case of triple flames. Flows and Chemical Reactions in Homogeneous Mixtures provides information on dimensional analysis, statistical thermodynamics with coupling between internal modes and chemical reactions, the apparition and damping of fluid turbulence as well as its statistical processing, bifurcations, flames in a confined medium and diffusion. Contents 1. Flows in Nozzles. 2. Chemical Reactors. 3. Laminar and Turbulent Flames. Appendix 1. Dimensionless Numbers, Similarity. Appendix 2. Thermodynamic Functions. Appendix 3.

Book excerpt: Part textbook, part exploratory work, this book aims to raise the awareness of students, physicists, and engineers in turbulence on the modeling of gravitationally induced turbulent mixing flows as produced, for instance, by Rayleigh-Taylor instabilities. The discussion is centered on the differences between single-fluid and two-fluid approaches, and it is illustrated with a 0D analysis of two specific elementary models in common use. Important deviations are shown to appear on many features, among others the prominence of directed energy, the simultaneous restitution of test cases, the responses to variable acceleration and shocks, and the behavior of various length scales.
