Book Synopsis Etude expérimentale et théorique de l'interaction aérodynamique entre un tourbillon d'extrémité d'aile et une surface portante en oscillation by : Frédéric Pous

This book was released on 1989 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse s'inscrit dans le cadre des études sur l'interaction tourbillon-surface portante, que l'on rencontre dans l'aérodynamique des voilures tournantes. Les travaux effectués sous le double aspect expérimental et théorique, visent à caractériser les effets instationnaires engendrés par un tourbillon d'extrémité sur un profil aval bidimensionnel oscillant en mouvement de tamis longitudinal. Dans un premier temps, l'étude expérimentale complète du tourbillon d'extrémité émis par la demi-aile montre que les caractéristiques instantanées de celui-ci sont fortement modifiées par l'oscillation du profil aval. Dans un deuxième temps, le comportement global, ainsi que les grandeurs locales sur le profil recepteur, sont évalués expérimentalement. En régime non décollé l'effet principal de l'interaction se situe sur le coefficient de moment, tandis que le décrochage dynamique reste prépondérant pour les grandes incidences géométriques. Sur le plan théorique, le code de calcul, repose sur la méthode des singularités, couplée à une configuration de nappe plane et rigide, formée de tourbillons en fer à cheval. L'influence réciproque du recepteur sur l'émetteur est introduite par l'intermédiaire de la loi expérimentale d'évolution de la circulation du tourbillon émis. Des confrontations calcul-expérience ont été réalisées dans différentes configurations d'écoulement en régimes stationnaire ou instationnaire et les résultats de ces confrontations montrent un bon accord, principalement sur les grandeurs instantanées
Book Synopsis Analyse expérimentale des paliers aérodynamiques by : Pierre Matta
Download or read book Analyse expérimentale des paliers aérodynamiques written by Pierre Matta and published by . This book was released on 2009 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les paliers aérodynamiques sont utilisés dans des machines de grande précision et de petite taille où se trouvent réunis les grandes vitesses de rotations avec les très faibles jeux. Plusieurs études numériques ont été faites pour déterminer les coefficients dynamiques des paliers à air mais les validations expérimentales sont toujours nécessaires. Un dispositif d'essai a été développé pour tester les paliers à air fonctionnant à une vitesse maximale de 60000 tr/min et sous différentes charges statiques. Les essais ont été faits sur des paliers aérodynamiques circulaires mais le dispositif peut tester d'autres types de paliers. Les excitations dynamiques sont appliquées par deux pots vibrants ou par un marteau d'impact et une méthode d'identification des coefficients dynamiques a été développée. Deux paliers aérodynamiques circulaires de 30 mm et 40 mm de diamètre avec L/D = 1 et un jeu radial de 22 μm ont été testés. Les résultats obtenus pour différentes vitesses de rotation et charges statiques ont été comparés avec le calcul théorique.

Book Synopsis Flows and Chemical Reactions in Heterogeneous Mixtures by : Roger Prud'homme
Download or read book Flows and Chemical Reactions in Heterogeneous Mixtures written by Roger Prud'homme and published by John Wiley & Sons. This book was released on 2014-12-03 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book - a sequel of previous publications 'Flows and Chemical Reactions' and 'Chemical Reactions in Flows and Homogeneous Mixtures' - is devoted to flows with chemical reactions in heterogeneous environments. Heterogeneous media in this volume include interfaces and lines. They may be the site of radiation. Each type of flow is the subject of a chapter in this volume. We consider first, in Chapter 1, the question of the generation of environments biphasic individuals: dusty gas, mist, bubble flow. Chapter 2 is devoted to the study at the mesoscopic scale: particle-fluid exchange of momentum and heat with determination of the respective exchange coefficients. In Chapter 3, we establish simplified equations of macroscopic balance for mass, for the momentum and energy, in the case of particles of one size (monodisperse suspension). Radiative phenomena are presented in Chapter 5.

Book Synopsis Acoustics, Aeroacoustics and Vibrations by : Fabien Anselmet
Download or read book Acoustics, Aeroacoustics and Vibrations written by Fabien Anselmet and published by John Wiley & Sons. This book was released on 2016-01-07 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 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.).

Download or read book Biomimicry written by Janine M. Benyus and published by Harper Collins. This book was released on 2009-08-11 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Repackaged with a new afterword, this "valuable and entertaining" (New York Times Book Review) book explores how scientists are adapting nature's best ideas to solve tough 21st century problems. Biomimicry is rapidly transforming life on earth. Biomimics study nature's most successful ideas over the past 3.5 million years, and adapt them for human use. The results are revolutionizing how materials are invented and how we compute, heal ourselves, repair the environment, and feed the world. Janine Benyus takes readers into the lab and in the field with maverick thinkers as they: discover miracle drugs by watching what chimps eat when they're sick; learn how to create by watching spiders weave fibers; harness energy by examining how a leaf converts sunlight into fuel in trillionths of a second; and many more examples. Composed of stories of vision and invention, personalities and pipe dreams, Biomimicry is must reading for anyone interested in the shape of our future.
