Download or read book Topologie des coulements tridimensionnels d coll s written by DÉLERY Jean and published by Lavoisier. This book was released on 2013-06-01 with total page 185 pages. 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.
Download or read book coulements et r actions chimiques 2 Applications aux m langes homog nes r actifs written by PRUD'HOMME Roger and published by Lavoisier. This book was released on 2013-06-01 with total page 254 pages. Available in PDF, EPUB and Kindle. 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.
Download or read book Heat and Moisture Transfer between Human Body and Environment written by Jean-Paul Fohr and published by John Wiley & Sons. This book was released on 2015-12-07 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human adaptation under cold or hot temperatures has always required specific fabrics for clothing. Sports or protective garment companies propose to improve performance or safety. Behind thermal comfort lays many physical/physiological topics: human thermoregulation loop, natural or forced convection, heat and vapor transfer through porous textile layers, solar and infrared radiation effects. This book leads through progressive and pedagogic stages to discern the weight of all the concerned physical parameters.
Download or read book Energy Systems written by Renaud Gicquel and published by CRC Press. This book was released on 2012-01-27 with total page 1064 pages. Available in PDF, EPUB and Kindle. Book excerpt: Considered as particularly difficult by generations of students and engineers, thermodynamics applied to energy systems can now be taught with an original instruction method. Energy Systems applies a completely different approach to the calculation, application and theory of multiple energy conversion technologies. It aims to create the reader’s foundation for understanding and applying the design principles to all kinds of energy cycles, including renewable energy. Proven to be simpler and more reflective than existing methods, it deals with energy system modeling, instead of the thermodynamic foundations, as the primary objective. Although its style is drastically different from other textbooks, no concession is done to coverage: with encouraging pace, the complete range from basic thermodynamics to the most advanced energy systems is addressed. The accompanying ThermoptimTM portal (http://direns.mines-paristech.fr/Sites/Thopt/en/co/_Arborescence_web.html) presents the software and manuals (in English and French) to solve over 200 examples, and programming and design tools for exercises of all levels of complexity. The reader is explained how to build appropriate models to bridge the technological reality with the theoretical basis of energy engineering. Offering quick overviews through e-learning modules moreover, the portal is user-friendly and enables to quickly become fully operational. Students can freely download the ThermoptimTM modeling software demo version (in seven languages) and extended options are available to lecturers. A professional edition is also available and has been adopted by many companies and research institutes worldwide - www.thermoptim.org This volume is intended as for courses in applied thermodynamics, energy systems, energy conversion, thermal engineering to senior undergraduate and graduate-level students in mechanical, energy, chemical and petroleum engineering. Students should already have taken a first year course in thermodynamics. The refreshing approach and exceptionally rich coverage make it a great reference tool for researchers and professionals also. Contains International Units (SI).

Download or read book Thermodynamique optimale en dimensions physiques finies written by FEIDT Michel and published by Lavoisier. This book was released on 2013-06-01 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: La thermodynamique doit aujourd’hui s’adapter à une problématique plus large, le développement durable. Par le biais d’une approche originale utilisant des outils renouvelés, cet ouvrage apporte des réponses à ce challenge sous deux aspects : - un aspect applicatif, par la méthodologie d'optimisation sous contrainte, qui conduit à des solutions optimales faciles à comparer à l'existant, et dessine les voies et potentiels d'amélioration encore disponibles ; - un aspect fondamental, qui correspond à une vision nouvelle de la thermodynamique des machines et des systèmes. Le livre s'écarte de l'approche classique de thermodynamique de l'équilibre, développée par Carnot, pour adopter une méthode qui allie les descriptions des phénomènes dynamiques de transfert et de conversion. À ces aspects pratiques de la vie courante, s'ajoute une vision plus profonde et fondamentale du monde, en particulier la notion d'évolution, intimement liée au second principe de thermodynamique. L’auteur Ingénieur et physicien, Michel Feidt est enseignant-chercheur en thermodynamique et énergétique à l'université de Lorraine. Il anime aussi une équipe de recherche dédiée aux études des systèmes et procédés énergétiques.
