Book Synopsis Contribution à l'étude de la convection naturelle par la technique polarographique by : Tan Siep Kheng
Download or read book Contribution à l'étude de la convection naturelle par la technique polarographique written by Tan Siep Kheng and published by . This book was released on 1977 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: On étudie expérimentalement le transfert de chaleur entre un cylindre horizontal et un fluide (avec l'air et avec l'eau). On montre comment une technique polarographique permet la mesure du frottement pariétal de vitesse dû à la convection naturelle qui se développe autour d'un cylindre chauffé. On étudie le mouvement d'un panache s'élevant au-dessus d'un cylindre horizontal chauffé par une mesure de la distribution de vitesse et de température dans la zone stable du panache et par mesure de son oscillation, et on étudie un arrangement vertical de cylindres horizontaux, ce qui permet de préciser l'influence du panache inferieur sur les cylindres supérieurs pour le transfert de chaleur entre chaque cylindre et le milieu ambiant.

Book Synopsis Contribution à l'étude de la convection naturelle au dessus de plaques horizontales de différentes topographie by : Sylvie Pretot

This book was released on 1999 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail concerne l'étude théorique et expérimentale de l'influence de la topographie d'une plaque horizontale sur les transferts par convection naturelle laminaire développés en son voisinage. La première partie est consacrée à la modélisation numérique de la convection naturelle qui se développe au-dessus de plaques horizontales soumises à un flux de densité uniforme et constante. Ces plaques de différentes topographies (plane, sinusoïdale et triangulaire) sont placées dans un milieu semi-infini (air, eau et huile). Les équations sont discrétisées en utilisant la technique des volumes de contrôle et le couplage entre les champs de vitesses et de pressions est assuré par l'algorithme SIMPLE. Les profilométries, sinusoïdale et triangulaire, sont ramenées, par une transformation homotopique, à une surface plane. La taille du domaine dans lequel se développe la convection naturelle est déterminée par un calcul itératif. Les résultats sont présentés sous forme de fonctions de courant, d'isothermes, de nombres de Nusselt. Des corrélations permettant de décrire le transfert de chaleur entre la plaque et le fluide, incluant le rapport amplitude sur période des protubérances, sont proposées. Ces résultats montrent que la morphologie de l'écoulement ainsi que les transferts entre la plaque et le fluide sont affectés, notamment par la forme des protubérances. La deuxième partie concerne l'analyse expérimentale par microscopie thermique à balayage et interférométrie holographique des champs de températures et de leurs évolutions spatio-temporelles. les résultats numériques et expérimentaux sont en bon accord.

Book Synopsis Electrochemical and Electrocatalytic Reactions of Carbon Dioxide by : B.P. Sullivan
Download or read book Electrochemical and Electrocatalytic Reactions of Carbon Dioxide written by B.P. Sullivan and published by Elsevier. This book was released on 2012-12-02 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recycling of atmospheric molecules for use as fuels and chemicals is a goal which can only be achieved through a deeper understanding of catalytic processes, particularly electrocatalysis whereby redox transformations can be interfaced with solar or nuclear energy input. Carbon dioxide is a prototypical small molecule in many regards since it is chemically inert. In addition, because of the likely role of carbon dioxide in global temperature cycles, it will be imperative in the future to regulate the output from industrial processes. The purpose of this book is to present a unified discussion of the carbon dioxide chemistry which is necessary for the understanding and design of electrochemically-driven processes for the reduction of carbon dioxide and to provide an impetus for the further development of electrocatalytic carbon dioxide chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: Despite the mechanisms of reservoir sedimentation being well known for a long time, sustainable and preventive measures are rarely taken into consideration in the design of new reservoirs. To avoid operational problems of powerhouses, sedimentation is often treated for existing reservoirs with measures which are efficient only for a limited time.Th

Download or read book Radiation Chemistry written by C.D. Jonah and published by Elsevier. This book was released on 2001-08-23 with total page 777 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the twentieth century, radiation chemistry emerged as a multi-faceted field encompassing all areas of science. Radiation chemical techniques are becoming increasingly popular and are being routinely used not only by chemists but also by biologists, polymer scientists, etc. "Radiation Chemistry: Present Status and Future Trends" presents an overall view of the different aspects of the subject. The chapters review the current status of the field and present the future opportunities in utilizing radiation chemical techniques. This will be of interest to chemists in general and in particular to radiation chemists, chemical kineticists, photochemists, physical-organic chemists and spectroscopists. In view of the diverse nature of the field, the book is a multi-authored effort by several experts in their particular areas of research. Six main areas, both basic and applied, were identified and the book is organized around them. The topics were selected in terms of their relative importance and the contribution of radiation chemistry to the general areas of chemistry, biology and physics. The topics covered are as diverse as gas phase radiation chemistry, the use of radiation chemical techniques, the treatment of water pollutants, the chemical basis of radiation biology, and muonium chemistry. The book also contains an update of the next generation electron accelerators.
