This book was released on 2012-12-06 with total page 1083 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid growth of literature on convective heat and mass transfer through porous media has brought both engineering and fundamental knowledge to a new state of completeness and depth. Additionally, several new questions of fundamental merit have arisen in several areas which bear direct relation to further advancement of basic knowledge and applications in this field. For example, the growth of fundamental heat transfer data and correlations for engineering use for saturated media has now reached the point where the relations for heat transfer coefficients and flow parameters are known well enough for design purposes. Multiple flow field regimes in natural convection have been identified in several important enclosure geometries. New questions have arisen on the nature of equations being used in theoretical studies, i. e. , the Validity of Darcy assumption is being brought into question; Wall effects in high and low velocity flow fields have been found to play a role in predicting transport coefficients; The formulation of transport problems in fractured media are being investigated as both an extension of those in a homogeneous medium and for application in engineering systems in geologic media and problems on saturated media are being addressed to determine their proper formulation and solution. The long standing problem of how to adequately formulate and solve problems of multi-phase heat and mass transfer in heterogeneous media is important in the technologies of chemical reactor engineering and enhanced oil recovery.

Available in PDF, EPUB and Kindle. Book excerpt: The present book contains papers that have been selected from contributions to the First International Symposium on Turbulent Shear Flows which was held from the 18th to 20th April 1977 at The Pennsylvania State University, University Park, Pennsylvania, USA. Attend ees from close to 20 countries presented over 100 contributions at this meeting in which many aspects of the current activities in turbulence research were covered. Five topics received particular attention at the Symposium: Free Flows Wall Flows Recirculating Flows Developments in Reynolds Stress Closures New Directions in Modeling This is also reflected in the five chapters of this book with contributions from research workers from different countries. Each chapter covers the most valuable contributions of the conference to the particular chapter topic. Of course, there were many additional good con tributions to each subject at the meeting but the limitation imposed on the length of this volume required that a selection be made. The realization of the First International Symposium on Turbulent Shear Flows was p- sible by the general support of: U. S. Army Research Office U. S. Navy Research Office Continuing Education Center of The Pennsylvania State University The conference organization was carried out by the organizing committee consisting of: F. Durst, Universitat Karlsruhe, Karlsruhe, Fed. Rep. of Germany V. W. Goldschmidt, Purdue University, West Lafayette, Ind. , USA B. E. Launder, University of California, Davis, Calif. , USA F. W. Schmidt, Pennsylvania State University, University Park, Penna.

Available in PDF, EPUB and Kindle. Book excerpt: Depuis plus d'un siècle, les instabilités hydrodynamiques se révèlent un champ d'étude foisonnant et constamment renouvelé, enrichi par un dialogue fructueux de la mécanique avec de nombreuses branches de la physique, en particulier les transitions de phase, l'optique et la chimie non linéaires, l'astrophysique et la géophysique. Des problèmes anciens et fondamentaux comme la transition vers la turbulence sont vivifiés par de nouvelles idées. De nouveaux champs d'étude émergent aussi, comme le contrôle des instabilités, les fluides non newtoniens ou diphasiques, et les milieux granulaires. Cet ouvrage, issu d'un cours de Master de l'université de Toulouse, s'adresse à tout étudiant, chercheur ou ingénieur désirant s'initier à ces questions. Il est structuré par la théorie des systèmes dynamiques, des bifurcations et des ruptures de symétrie. Les phénomènes sont discutés, autant que possible, en termes d'échelles caractéristiques et d'analyse dimensionnelle pour accéder aux mécanismes physiques. Les méthodes asymptotiques ont aussi une large place. De nombreuses études expérimentales sont discutées en détail. Chaque chapitre se termine par des exercices, qui sont souvent des ouvertures vers des problèmes nouveaux. Enfin, onze notices biographiques présentent quelques grands noms attachés à l'étude des instabilités.

Download or read book Instabilité thermoconvective d'un écoulement Poiseuille-Rayleigh-Bénard-Marangoni en canal ouvert à surface libre written by Lahcen Bammou and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plusieurs études tant numériques qu'expérimentales font état de la présence d'instabilités thermiques dans des films liquides chauffés uniformément par le bas pour des conditions aux limites et d'écoulements particuliers. La présence de ces instabilités modifiera les transferts thermiques associés. Le sujet de ce travail de thèse consiste à étudier numériquement les instabilités thermoconvectives d'un écoulement laminaire tridimensionnel de convection mixte dans un canal horizontal à surface libre. Les variations de la tension de surface avec la température (effet Marangoni ou effet thermocapillaire) sont prises en compte. Bien que d'un intérêt certain pour de nombreuses applications industrielles, cette situation a été très peu étudiée d'un point de vue académique dans la configuration considérée ici. Dans cette de configuration plusieurs types de structures thermoconvectives sont susceptibles d'apparaître. Lorsque les forces induites par les courants de convection naturelle, forcée et thermocapillaire sont du même ordre de grandeur, les premiers résultats montrent un développement des instabilités sous forme de rouleaux convectifs longitudinaux stationnaires semblables à ceux rencontrés pour des écoulements de type Poiseuille-Rayleigh-Bénard. A notre connaissance, c'est la première fois que l'écoulement de convection de type Poiseuille-Rayleigh-Bénard associé aux effets Marangoni est étudié. Le nombre et la distribution spatiale des rouleaux convectifs le long du canal dépendent des conditions de l'écoulement. Nous proposons une étude numérique pour ces conditions particulières d'écoulement pouvant conduire à des instabilités avec une évaluation de leur effet sur les transferts de chaleur. Les équations de Navier-Stokes et de l'énergie sont résolues numériquement par la méthode de volumes finis en prenant en compte les effets thermocapillaires. Les résultats présentés concernent l'influence des paramètres contrôlant l'écoulement (nombres de Reynolds, de Rayleigh, de Biot, de Marangoni et le rapport de forme) sur les motifs de l'écoulement et les échanges thermiques. Dans une seconde partie du travail, complémentaire à la première, une analyse de stabilité linéaire de l'écoulement dans un canal ouvert à surface libre d'extension latérale infinie est réalisée en utilisant la méthode spectrale de type collocation Chebyshev pour résoudre un système aux valeurs propres. Les diagrammes de stabilité déterminant les seuils des paramètres conduisant à l'instabilité thermoconvective ont été obtenus et analysés, ainsi que les structures spatiales associées.
