This book was released on 1996 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: NOUS PROPOSONS DANS CE TRAVAIL UNE ETUDE DE FAISABILITE POUR L'ESTIMATION DU FLUX INCIDENT ET DES PROFILS INTERNES DE TEMPERATURE DANS UN MATERIAU SEMI-TRANSPARENT A PARTIR DE MESURES INTERNES DE TEMPERATURE EN REGIME TRANSITOIRE. UNE METHODE EST PROPOSEE POUR RESOUDRE CE PROBLEME: IL S'AGIT D'UNE METHODE DE RETOUR VERS LA SURFACE, QUI PREND EN COMPTE LES TERMES SOURCES CALCULES A PARTIR DE L'EQUATION DE TRANSFERT RADIATIF (ETR). L'ORIGINALITE DE CE TRAVAIL CONSISTE A FAIRE L'INVERSION SUR L'EQUATION DE L'ENERGIE CONTRAIREMENT AU PROBLEME INVERSE DE RAYONNEMENT OU L'INVERSION EST EFFECTUEE A PARTIR DE L'ETR. LE CAS D'UNE PLAQUE PLANE PARALLELE MONODIMENSIONNELLE SEMI-TRANSPARENTE NON-DIFFUSANTE AVEC DES PROPRIETES THERMOPHYSIQUES VARIABLES ET COMPRISE ENTRE DEUX PAROIS OPAQUES EST ETUDIE. TOUTEFOIS, L'ALGORITHME D'INVERSION DE L'EQUATION DE L'ENERGIE NECESSITE LA SOLUTION DIRECTE DE L'ETR, CELLE-CI EST RESOLUE DE DEUX FACONS DIFFERENTES: POUR LE CAS DE PROPRIETES CONSTANTES LA SOLUTION EXACTE A ETE UTILISEE ET POUR LES CAS PLUS GENERAUX NOUS AVONS CONSIDERE UN MODELE GRIS PAR BANDES TRAITE PAR LA METHODE DES ORDONNEES DISCRETES. POUR RESOUDRE L'EQUATION DE L'ENERGIE NOUS AVONS CHOISI LA METHODE DES DIFFERENCES FINIES. LA FAISABILITE DE CETTE APPROCHE EST DEMONTREE PAR UNE SIMULATION NUMERIQUE EN UTILISANT DES DONNEES EXACTES ET BRUITEES SUIVANT DES CAS-TESTS PROPOSES DANS LA LITTERATURE. CETTE ETUDE MONTRE QUE LA CONTRIBUTION DU RAYONNEMENT COMPLIQUE L'ALGORITHME D'INVERSION MAIS N'ENGENDRE PAS D'INSTABILITE PARTICULIERE

This book was released on 1995 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL A POUR OBJET L'ANALYSE DU COUPLAGE CONDUCTION-CONVECTION FORCEE EN REGIME THERMIQUE VARIABLE, DANS LE CAS D'UN ECOULEMENT FLUIDE ENTRE PLAQUES PARALLELES EPAISSES. IL S'AGIT DE PRECISER LA FONCTION DE TRANSFERT OBTENUE POUR UNE EXCITATION PERIODIQUE IMPOSEE A L'ENTREE DU FLUIDE. L'ETUDE COMPREND TROIS PARTIES: LA PREMIERE EST CONSACREE A L'ANALYSE THEORIQUE DANS LE CAS D'UN ECOULEMENT LAMINAIRE A PLAN DIRECTEUR. LE COUPLAGE EST TRAITE EN ECRIVANT L'EGALITE DES FLUX ET DES TEMPERATURES A L'INTERFACE (CONDITION LIMITE DITE DE TYPE 4). UNE SOLUTION ANALYTIQUE A ETE DEVELOPPEE MOYENNANT L'HYPOTHESE D'UN PROFIL DE VITESSE UNIFORME (SLUG FLOW). CE PROBLEME EST EGALEMENT RESOLU A L'AIDE DU MODELE QUASI-STATIONNAIRE, LE COUPLAGE A L'INTERFACE EST ALORS ASSURE EN INTRODUISANT LA NOTION DE COEFFICIENT DE CONVECTION. LA DEUXIEME PARTIE CONCERNE LA SIMULATION NUMERIQUE D'UN ECOULEMENT FLUIDE EN REGIME LAMINAIRE ENTRE DEUX PLAQUES PARALLELES. LE CHAMP DYNAMIQUE EST CONSIDERE ETABLI PARABOLIQUE. LA REPONSE THERMIQUE EST ETUDIEE EN FONCTION DES DIFFERENTS PARAMETRES DU PROBLEME, TELS QUE LA FREQUENCE DU SIGNAL D'ENTREE ET LES CARACTERISTIQUES THERMOPHYSIQUES DU FLUIDE ET DU SOLIDE. LE MODELE NUMERIQUE UTILISANT UNE FORMULATION EXPLICITE AUX DIFFERENCES FINIES EST VALIDE PAR RAPPORT A LA SOLUTION EXACTE DEVELOPPEE DANS LA PREMIERE PARTIE. EN REGIME TURBULENT, DES PROFILS CLASSIQUES DE DISTRIBUTION DE VITESSE ET DE VISCOSITE SONT UTILISES DANS UN MODELE PSEUDO-LAMINAIRE. LES RESULTATS SONT ALORS COMPARES A CEUX OBTENUS SIMPLEMENT PAR L'UTILISATION DU NOMBRE DE NUSSELT. LA TROISIEME PARTIE EST RELATIVE A L'ETUDE EXPERIMENTALE D'UN ECOULEMENT D'EAU DANS UN CANAL RECTANGULAIRE DE SECTION 300 X 20 MM#2 ET DE LONGUEUR 3 M. LES PAROIS SONT EN ACIER INOXYDABLE DE 5 MM D'EPAISSEUR. LE FLUIDE ABORDE LE CANAL AINSI DEFINI AVEC UNE TEMPERATURE D'ENTREE EVOLUANT SELON UNE LOI TEMPORELLE PERIODIQUE. ON S'INTERESSE A LA DISTRIBUTION DE TEMPERATURE LONGITUDINALE DANS L'AXE DU CANAL ET A LA PAROI. EN PRATIQUE, NOUS DISPOSONS DE DEUX PARAMETRES, A SAVOIR LE NOMBRE DE REYNOLDS ET LA FREQUENCE DU SIGNAL D'ENTREE. LES RESULTATS EXPERIMENTAUX SONT CONFRONTES AUX MODELES PRECEDENTS

LE TRAVAIL EXPERIMENTAL REPOSE SUR LA MISE EN OEUVRE D'UNE PROCEDURE DE DETERMINATION DU COEFFICIENT DE TRANSFERT PAROI-FLUIDE ET DE SES VARIATIONS SPATIO-TEMPORELLES PAR THERMOGRAPHIE INFRAROUGE

Book excerpt: LA SOLUTION DE CE TYPE DE PROBLEMES EXIGE CELLE DES PROBLEMES AUX VALEURS PROPRES QUI NE SONT PAS DES SYSTEMES CONVENTIONNELS DE STURM-LIOUVILLE DONT LA RESOLUTION AVEC DES TECHNIQUES CLASSIQUES NE SONT PAS GARANTIES D'OUBLI DE VALEURS PROPRES AU COURS DE LEUR CALCUL. POUR RENDRE FIABLE LE MODELE ANALYTIQUE, ON DEVELOPPE UN ALGORITHME EFFICACE POUR LA RESOLUTION DES PROBLEMES AUX VALEURS PROPRES RESULTANT D'UNE PAROI MULTICOUCHE SEULE ET DE PLUSIEURS PAROIS COMPOSITES PLANE MULTIPLEMENT COUPLEES. ON PROPOSE UNE PROCEDURE DE LINEARISATION DES EQUATIONS REGISSANT LES ECHANGES THERMIQUES DANS DES FOURS DE TRAITEMENT THERMIQUE CHAUFFES PAR DES RESISTANCES ELECTRIQUES. COMME EXEMPLE D'APPLICATION, ON SIMULE LE FONCTIONNEMENT D'UN FOUR A CHARGE

Download or read book Brazilian Studies in Philosophy and History of Science written by Décio Krause and published by Springer Science & Business Media. This book was released on 2011-01-27 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, The Brazilian Studies in the Philosophy and History of Science, is the first attempt to present to a general audience, works from Brazil on this subject. The included papers are original, covering a remarkable number of relevant topics of philosophy of science, logic and on the history of science. The Brazilian community has increased in the last years in quantity and in quality of the works, most of them being published in respectable international journals on the subject. The chapters of this volume are forwarded by a general introduction, which aims to sketch not only the contents of the chapters, but it is conceived as a historical and conceptual guide to the development of the field in Brazil. The introduction intends to be useful to the reader, and not only to the specialist, helping them to evaluate the increase in production of this country within the international context.

Download or read book Metamorphoses written by Emanuele Coccia and published by John Wiley & Sons. This book was released on 2021-06-09 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are all fascinated by the mystery of metamorphosis – of the caterpillar that transforms itself into a butterfly. Their bodies have almost nothing in common. They don’t share the same world: one crawls on the ground and the other flutters its wings in the air. And yet they are one and the same life. Emanuele Coccia argues that metamorphosis – the phenomenon that allows the same life to subsist in disparate bodies – is the relationship that binds all species together and unites the living with the non-living. Bacteria, viruses, fungi, plants, animals: they are all one and the same life. Each species, including the human species, is the metamorphosis of all those that preceded it – the same life, cobbling together a new body and a new form in order to exist differently. And there is no opposition between the living and the non-living: life is always the reincarnation of the non-living, a carnival of the telluric substance of a planet – the Earth – that continually draws new faces and new ways of being out of even the smallest particle of its disparate body. By highlighting what joins humans together with other forms of life, Coccia’s brilliant reflection on metamorphosis encourages us to abandon our view of the human species as static and independent and to recognize instead that we are part of a much larger and interconnected form of life.

Available in PDF, EPUB and Kindle. Book excerpt: From the Preface to the first edition (1906): "A few of the most modern books on the Theory of Functions devote some pages to the establishment of certain results belonging to our subject, and required for the special purposes in hand... But we may fairly claim that the present work is the first attempt at a systematic exposition of the subject as a whole."
