Book Description
L'ETUDE EXPERIMENTALE FOURNIT D'UNE PART UNE BANQUE DE DONNEES ORIGINALES SUR LA STRUCTURE LOCALE DES ECOULEMENTS DANS CHAQUE PHASE ET DANS LES VAGUES DE VENT; ET D'AUTRE PART UN ENSEMBLE DE RESULTATS SUR LES INTERACTIONS DYNAMIQUES FLUIDE-FLUIDE ET FLUIDES-PAROIS. ON MET EN EVIDENCE L'EXISTENCE D'UNE STRUCTURE CELLULAIRE IMPORTANTE GENEREE PAR LES VAGUES. ON PROPOSE UN MODELE ANALYTIQUE QUI SOULIGNE LE ROLE FONDAMENTAL DES TERMES DE TRANSPORT DANS LES BILANS DE QUANTITE DE MOUVEMENT ET DE TURBULENCE SOUS LES VAGUES

Book Description
On présente les résultats de modélisation locale de l'écoulement co-courant de gaz et de liquide en canal rectangulaire et en conduite de section circulaire. Le modèle proposé rend compte de la structure cellulaire dans la phase liquide. La validation du modèle à partir des essais expérimentaux en canal rectangulaire et en conduite circulaire s'avère satisfaisante. L'étude asymptotique élaboré permet de générer le champ de l'écoulement secondaire et rend compte de son importance pour la compréhension locale de l'écoulement.

Book Description
This is an up-to-date review of recent advances in the study of two-phase flows, with focus on gas-liquid flows, liquid-liquid flows, and particle transport in turbulent flows. The book is divided into several chapters, which after introducing basic concepts lead the reader through a more complex treatment of the subjects. The reader will find an extensive review of both the older and the more recent literature, with abundance of formulas, correlations, graphs and tables. A comprehensive (though non exhaustive) list of bibliographic references is provided at the end of each chapter. The volume is especially indicated for researchers who would like to carry out experimental, theoretical or computational work on two-phase flows, as well as for professionals who wish to learn more about this topic.

Book Description
This volume of the Advances in Engineering Fluid Mechanics Series covers topics in hydrodynamics related to polymerization of elastomers and plastics. Emphasis is given to advanced concepts in multiphase reactor systems often used in the manufacturing of products. This volume is comprised of 30 chapters that address key subject areas such as multiphase mixing concepts, multicomponet reactors and the hydrodynamics associated with their operations, and slurry flow behavior associated with non-Newtonian flows.

Book Description
L'ETUDE DE LA ZONE DE DEVELOPPEMENT DE LA COUCHE LIMITE INTERFACIALE A NECESSITE LA REALISATION D'UN CONTACTEUR GAZ LIQUIDE DE GRANDES DIMENSIONS. LA STRUCTURE DE LA TURBULENCE EN ECOULEMENT STRATIFIE EST PRECISEE PAR DES MESURES DE LA VITESSE MOYENNE DE L'INTENSITE ET DES FLUCTUATIONS TURBULENTES, ET DE LA CONTRAINTE DE REYNOLDS, AVEC DES DISPOSITIFS A FIL CHAUD, FILM CHAUD AU LASER. IL APPARAIT QUE LE RAPPORT DES FROTTEMENTS A L'INTERFACE ET SUR LE FOND EST LE PARAMETRE DETERMINANT, ET QU'IL EST POSSIBLE, AVEC CES RESULTATS EXPERIMENTAUX, D'AMELIORER LES MODELES EXISTANTS

Book Description
This book is dedicated to the tube flow of viscoelastic fluids and Newtonian single and multi-phase particle-laden fluids. This succinct volume collects the most recent analytical developments and experimental findings, in particular in predicting the secondary field, highlighting the historical developments which led to the progress made. This book brings a fresh and unique perspective and covers and interprets efforts to model laminar flow of viscoelastic fluids in tubes and laminar and turbulent flow of single and multi-phase particle-laden flow of linear fluids in the light of the latest findings.
