This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'écoulement de Couette plan peut être considéré comme le prototype d'une couche cisaillée avec un comportement de transition sous-critique, étant donné que cet écoulement est linéairement stable pour tout nombre de Reynolds. La transition doit par conséquent y être déclenchée par des perturbations d'amplitude finie, et ce travail a précisément pour objet la description de tels états non-linéaires. En un premier temps, nous abordons la question de l'existence d'équilibres non-linéaires bidimensionnels. Pour cela, nous avons suivi numériquement des ondes progressives non-linéaires présentes dans l'écoulement de Poiseuille, jusqu'à obtenir des équilibres non-linéaires 2D pour Couette plan. Le principal résultat est que des équilibres dans Poiseuille plan, (ondes progressives) évoluent, lorsque l'on atteint la limite de Couette, vers des états non-linéaires stationnaires, avec une structure spatiale isolée. Les solutions calculées ainsi existent jusqu'à des nombres de Reynolds autour de 1500. Ces états non-linéaires constituent un nouvel état de base pour une étude de stabilité secondaire, par rapport à des perturbations secondaires 2D et 3D. Comme dans l'écoulement de Poiseuille plan ou la couche limite de Blasius, les perturbations 3D dominent clairement la dynamique au voisinage de ces états, étant donné que les facteurs d'amplification temporelle des modes 3D sont d'un ordre de grandeur plus élevé que ceux des perturbations 2D. De plus, les modes secondaires présentent aussi une structure isolée dans la direction longitudinale, tandis que les longueurs d'ondes transverses sont du même ordre de grandeur que celles observées dans Poiseuille plan. Enfin, nous présentons des calculs d'ondes non-linéaires 3D issues de points de bifurcation secondaire, qui ont permis d'atteindre des solutions existant jusqu'à re=1000. Ces états possèdent une structure spatialement isolée dans la direction longitudinale et périodique dans la direction transverse, en accord qualitatif avec des études expérimentales.

Download or read book Genmix written by D Brian Spalding and published by Elsevier. This book was released on 2014-05-18 with total page 393 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Calculations in Furnace Technology written by Clive Davies and published by Elsevier. This book was released on 2016-05-13 with total page 287 pages. 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.

Download or read book Emissions from Continuous Combustion Systems written by W. Cornelius and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume documents the proceedings of the Symposium on Emissions from Continuous Combustion Systems that was held at the General Motors Research Laboratories, Warren, Michigan on September 27 and 28, 1971. This symposium was the fifteenth in an annual series presented by the Research Laboratories. Each symposium has covered a different technical discipline. To be selected as the theme of a symposium, the subject must be timely and of vital interest to General Motors as well as to the technical community at large. For each symposium, the practice is to solicit papers at the forefront of research from recognized authorities in the technical discipline of interest. Approximately sixty scientists and engineers from academic, government and industrial circles in this country and abroad are then invited to join about an equal number of General Motors technical personnel to discuss freely the commissioned papers. The technical portion of the meeting is supplemented by social functions at which ample time is afforded for informal exchanges of ideas amongst the participants. By such a direct interaction of a small and select group of informed participants, it is hoped to extend the boundaries of research in the selected technical field.
