Book excerpt: L'évolution des stratégies d'injection du combustible dans les moteurs automobiles a fait apparaître de nouvelles problématiques. Parmi celles-ci, l'existence d'un dépôt de carburant sur les parois de la chambre de combustion a un impact sur les performances environnementales du moteur. En effet, l'évaporation de ce film liquide en proche paroi ne peut qu'influencer de manière sensible la phase de combustion. L'objectif de ce travail était de mettre en place une configuration académique maîtrisée et les diagnostics nécessaires à une première analyse phénoménologique du comportement et de l'évaporation d'un film liquide combustible déposé sur une paroi interagissant avec la combustion en phase gazeuse. L'approche expérimentale choisie a permis de générer un dépôt d'heptane liquide contrôlé sur une paroi verticale. Celle-ci est positionnée dans un écoulement ascendant de prémélange air/méthane dans lequel une flamme oblique est stabilisée sur un barreau. En parallèle, un diagnostic de mesure a été développé pour étudier les propriétés du film. Ce système d'interférométrie à faible cohérence a permis de réaliser une mesure locale simultanée de la température de paroi et de l'épaisseur du film en présence de l'écoulement réactif. Dans un premier temps, l'étude de configurations non réactives a permis de préciser les caractéristiques du film et de son évaporation, lorsque celui-ci s'écoule à contre-courant de l'écoulement gazeux. Plusieurs comportements types ont été mis en évidence et analysés. En présence de la flamme, une première approche a été consacrée à l'évolution des mécanismes qui influencent l'évaporation du film et son comportement par rapport au cas non réactif. Enfin, une analyse phénoménologique de l'impact de l'évaporation au sein de la couche limite sur les caractéristiques du front de flamme a été menée. Celle-ci a permis de mettre en évidence l'effet rétroactif de ce dernier sur le mélange des vapeurs, et une forte diversité des zones réactionnelles dans l'espace.

Book excerpt: Genmix: A General Computer Program for Two-dimensional Parabolic Phenomena explains a computer program called GENMIX. The main intention of the program is to be used as a tool of instructions. The name of the program is a mixture of two considerations: its generality and its concern for mixing processes. The book aims to help the potential user to understand the physical and mathematical basis of the topic computer program. It is also the aim of the book to make the program applicable to practical problems. The book is arranged in such a way as to parallel a course of lectures and associated computer-workshop sessions wherein the student is allowed to do some elementary computations as soon as he has gained some knowledge of the method. The book contains the mathematical, physical, and computer-coding aspects of the program. Concepts such as the boundary layer, two-dimensional, and steady- flow are defined and discussed in depth. The text will be a useful tool for computer instructors and students.

Available in PDF, EPUB and Kindle. Book excerpt: In spite of the potential use of nanomaterials as tissue engineering devices, implants, biosensors, drug delivery devices, etc., there has yet to be a compilation of the risks associated with the in vivo use of nanomaterials. There are numerous and well-known risks because of the size of nanoparticles. For example, nanoparticles can cross cell membranes and enter the cytoplasm undetected. The aim of this book is to provide one of the first (if not the first) detailed views of how cells and tissues in the body deal with nanoparticles. This is important not only for implantable devices, but also for the manufacturing of nanophase materials when particles can be inhaled or enter the body through the skin. Only by compiling research at the intersection of nanoparticles and biological processes can we determine if nanophase materials are safe to be manufactured, handled, and/or implanted for various medical applications.

Available in PDF, EPUB and Kindle. Book excerpt: Calculations in Furnace Technology presents the theoretical and practical aspects of furnace technology. This book provides information pertinent to the development, application, and efficiency of furnace technology. Organized into eight chapters, this book begins with an overview of the exothermic reactions that occur when carbon, hydrogen, and sulfur are burned to release the energy available in the fuel. This text then evaluates the efficiencies to measure the quantity of fuel used, of flue gases leaving the plant, of air entering, and the heat lost to the surroundings. Other chapters consider that it is important to determine the amount of carbon discharged with the ashes, the quantity and composition of any tar produced, so that a carbon balance can be applied. The final chapter describes the various reactions within the furnace atmosphere and between charges and atmosphere. This book is a valuable resource for fuel technologists, heating and ventilating engineers, and plant operators.

Symposium and published by . This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Conference Proceedings contains 38 papers presented at the Propulsion and Energetics Panel 73rd Symposium on 'Aircraft Fire Safety' which was held 22 - 26 May 1989 in Sintra, Portugal. The Symposium was arranged in the following sessions: Review of Fire-Related Aircraft Accidents (3); Fire Safety Standards and Research Programmes (6); Aircraft Internal Fires (9); Aircraft External Fires (2); Fire Safety of Military Weapon Systems (3); Fire Hardening by Advanced Materials and Structural Design (8); Passenger Behaviour in Emergency Situations (3); and Passenger Protective Equipment (4). The Technical Evaluation Report and and Addendum are included at the beginning of the Proceedings. Questions and answers of the discussions follow each paper. The last AGARD review on the subject took place in a Specialists' Meeting in 1975, followed by a Working Group Report in 1979 and Lecture Series in 1982. The purpose of the Symposium was a review of the present state-of-the-art and of the last improvements. Although the safety standards in aviation are already very high, there is still room for improvements. They are listed in the Conclusions and Recommendations of the Technical Evaluation Report and in the Addendum.
