This book was released on 1995 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: UN DES PROBLEMES IMPORTANTS DANS L'ETUDE DES ECOULEMENTS DE COUCHE LIMITE EST LA COMPREHENSION ET LA MODIFICATION DU PASSAGE DE L'ETAT LAMINAIRE A L'ETAT TURBULENT. ETANT DONNE QUE CETTE TRANSITION EST GOUVERNEE PAR L'APPARITION D'INSTABILITES, NOUS NOUS INTERESSONS ICI A LEUR MODIFICATION. POUR CELA NOUS CONSIDERONS LE CAS DE L'ECOULEMENT DE POISEUILLE PLAN DEFINI PAR UN FLUIDE S'ECOULANT, ENTRE DEUX PLAQUES PLANES RIGIDES INFINIES, SOUS L'EFFET D'UN GRADIENT DE PRESSION. ON ENVISAGE ALORS DEUX MANIERES DE MODIFIER LES INSTABILITES DANS CE TYPE D'ECOULEMENT. DANS UNE PREMIERE PARTIE ON CHANGE LES CONDITIONS AUX LIMITES EN SUBSTITUANT L'UNE DES PLAQUES RIGIDES PAR UNE SURFACE SOUPLE ELASTIQUE MISE EN MOUVEMENT SOUS LES CONTRAINTES DU FLUIDE. CETTE ETUDE S'INSPIRE DES TRAVAUX DE CARPENTER ET GARRAD (1985). DANS LA DEUXIEME PARTIE, NOUS MODIFIONS LA LOI DE COMPORTEMENT DU FLUIDE: LE FLUIDE NEWTONIEN EST REMPLACE PAR UN FLUIDE NON-NEWTONIEN DECRIT PAR UNE LOI DE COMPORTEMENT NON-LINEAIRE DE TYPE GIESEKUS (1982). NOUS EFFECTUONS DANS CES DEUX PARTIES NON SEULEMENT UNE ETUDE LINEAIRE CLASSIQUE DES INSTABILITES MAIS EGALEMENT L'ETUDE DE L'EVOLUTION FAIBLEMENT NON-LINEAIRE DES PERTURBATIONS AU VOISINAGE DU SEUIL CRITIQUE DE LA STABILITE LINEAIRE QUI CONDUIT AU CALCUL D'UNE EQUATION D'AMPLITUDE DE TYPE GINZBURG-LANDAU

This book was released on 1998 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'ECOULEMENT POISEUILLE PLAN MULTICOUCHE DE FLUIDES OLDROYD-B MODELISE LE PROCESSUS DE COEXTRUSION. L'ETUDE DE LA STABILITE LINEAIRE DE L'ECOULEMENT MONOCOUCHE MET EN EVIDENCE L'EXISTENCE D'UN SPECTRE CONTINU, POUVANT ENTRAINER UNE FAUSSE INSTABILITE ET D'UN SPECTRE DISCRET, DONT ON PRECISE LE COMPORTEMENT EN FONCTIONS DES PARAMETRES. PUIS, PROCEDANT A L'ANALYSE NON-LINEAIRE, LA NATURE SOUS-CRITIQUE DE LA BIFURCATION DE HOPF EST DEMONTREE. LES RESULTATS DE LA STABILITE DE L'ECOULEMENT BI-COUCHE RAPPELES, LA STABILITE DE L'ECOULEMENT SYMETRIQUE TROIS COUCHES EST ETUDIEE AUX LONGUES ONDES ET AUX ONDES MODEREES. DEUX MODES DITS VARIQUEUX ET SINUEUX, OBSERVES LORS D'EXPERIENCES DE COEXTRUSION CONCENTRIQUE, DESTABILISENT L'ECOULEMENT. L'ETUDE DE LA STABILITE EST ETENDU AU CAS D'UN ECOULEMENT NON SYMETRIQUE. L'IMPORTANCE DES SAUTS DE LA DERIVEE PREMIERE DE LA VITESSE DE L'ECOULEMENT DE BASE AUX INTERFACES EST NOTEE ET PERMET D'IDENTIFIER L'INTERFACE RESPONSABLE DE L'INSTABILITE. LA CONVEXITE DU PROFIL DES VITESSES, DIRECTEMENT LIEE A CES SAUTS, S'AVERE UNE CONDITION NECESSAIRE A LA STABILITE. DES ZONES DE RESONNANCE, DONT UNE CONDITION NECESSAIRE D'EXISTENCE EST EXPRIMEE EN FONCTION DU SIGNE DES SAUTS, CONDUISENT A UNE INSTABILITE INDEPENDANTE DU CARACTERE NON-NEWTONIEN DES FLUIDES. ENFIN, LA STABILITE AUX LONGUES ONDES DE L'ECOULEMENT TROIS COUCHES, LA COUCHE CENTRALE ETANT FINE PAR RAPPORT AUX DEUX COUCHES EXTERIEURES, EST CONSIDEREE ET DEUX VALEURS PROPRES INTERFACIALES SONT IDENTIFIEES : L'UNE CORRESPONDANT A CELLE PROVENANT DES DEUX COUCHES EXTERIEURES TANDIS QUE L'AUTRE TRADUIT L'INFLUENCE DE LA COUCHE MINCE. DE CETTE MANIERE, ON DONNE DES REGLES SIMPLES PERMETTANT DE CHOISIR LES CONSTANTES RHEOLOGIQUES DU FLUIDE CENTRAL DE SORTE QUE LA STABILITE SOIT DONNEE PAR LA VALEUR PROPRE ASSOCIEE AUX DEUX COUCHES EXTERIEURES.

Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.
Book Synopsis Biotransformation of Waste Biomass into High Value Biochemicals by : Satinder Kaur Brar
Download or read book Biotransformation of Waste Biomass into High Value Biochemicals written by Satinder Kaur Brar and published by Springer Science & Business Media. This book was released on 2013-09-24 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agro-industrial wastes are end-products emerging after industrial processing operations and also from their treatment and disposal e.g. solid fruit wastes and sludge. The agro-industrial wastes are often present in multiphase and comprise multicomponent. Nevertheless, these wastes are a goldmine as they possess valuable organic matter which can be diverted towards high value products ranging from polymers to antibiotics to platform chemicals. There have been plenty of books published on bioenergy, enzymes and organic acids, among others. However, this emerging field of biochemical has not yet been covered so far which is an important entity of the biorefinery model from waste biomass and needs to be understood from fundamental, applied as well as commercial perspective which has been laid out in this book.
