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 Internal Flow written by E. M. Greitzer and published by Cambridge University Press. This book was released on 2007-02-26 with total page 739 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the analysis and behaviour of internal flows encountered in propulsion systems, fluid machinery (compressors, turbines and pumps) and ducts (diffusers, nozzles and combustion chambers). The focus is on phenomena that are important in setting the performance of a broad range of fluid devices. The authors show that even for complex processes one can learn a great deal about the behaviour of such devices from a clear understanding and rigorous use of basic principles. Throughout the book they illustrate theoretical principles by reference to technological applications. The strong emphasis on fundamentals, however, means that the ideas presented can be applied beyond internal flow to other types of fluid motion. The book equips students and practising engineers with a range of new analytical tools. These tools offer enhanced interpretation and application of both experimental measurements and the computational procedures that characterize modern fluids engineering.
