This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans cette thèse, nous étudions des écoulements caractérisés par un faible nombre de Mach. Dans une première partie, nous développons un schéma numérique permettant la résolution des équations de Navier-Stokes à faible nombre de Mach. L'équation de continuité est résolue par une méthode de volumes finis, tandis que l'équation de conservation de la quantité de mouvement et l'équation d'évolution de la température sont résolues par éléments finis. Le schéma ainsi développé assure la préservation des états constants. Dans une seconde partie, nous faisons l'analyse d'un modèle de type faible Mach spécifique, dans lequel la pression thermodynamique est considérée constante, et la viscosité est une fonction particulière de la température. Nous montrons l'existence, l'unicité et la régularité des solutions, ainsi qu'un résultat de principe du maximum pour la température. Enfin dans une troisième partie, nous développons un schéma numérique permettant de simuler les équations de ce modèle. L'accent est mis sur la discrétisation de l'équation de température, qui est de type volumes finis. Plusieurs schémas sont étudiés et comparés sur des critères de précision et de respect du principe du maximum. L'équation de conservation de la quantité de mouvement est discrétisée par éléments finis, définissant un nouveau schéma combiné.

Available in PDF, EPUB and Kindle. Book excerpt: The future evolution of the debris environment will be forecast on the basis of traffic models and possible hazard mitigation practices. The text shows how large trackable objects will have re-entry pinpointed and predictions made on related risk assessment for possible ground impact. Models will also be described for meteoroids which are also a prevailing risk.

Download or read book Optimal Shape Design for Elliptic Systems written by O. Pironneau and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of optimal shape design can be arrived at by asking the following question: "What is the best shape for a physical system?" This book is an applications-oriented study of such physical systems; in particular, those which can be described by an elliptic partial differential equation and where the shape is found by the minimum of a single criterion function. There are many problems of this type in high-technology industries. In fact, most numerical simulations of physical systems are solved not to gain better understanding of the phenomena but to obtain better control and design. Problems of this type are described in Chapter 2. Traditionally, optimal shape design has been treated as a branch of the calculus of variations and more specifically of optimal control. This subject interfaces with no less than four fields: optimization, optimal control, partial differential equations (PDEs), and their numerical solutions-this is the most difficult aspect of the subject. Each of these fields is reviewed briefly: PDEs (Chapter 1), optimization (Chapter 4), optimal control (Chapter 5), and numerical methods (Chapters 1 and 4).

Available in PDF, EPUB and Kindle. Book excerpt: Aerodynamics, from a modern point of view, is a branch of physics that study physical laws and their applications, regarding the displacement of a body into a fluid, such concept could be applied to any body moving in a fluid at rest or any fluid moving around a body at rest. This Book covers a small part of the numerous cases of stationary and non stationary aerodynamics; wave generation and propagation; wind energy; flow control techniques and, also, sports aerodynamics. It's not an undergraduate text but is thought to be useful for those teachers and/or researchers which work in the several branches of applied aerodynamics and/or applied fluid dynamics, from experiments procedures to computational methods.

Available in PDF, EPUB and Kindle. Book excerpt: "This report consists of lecture notes of an AGARD Fluid Dynamics Panel Special Course. These notes provide the latest information on the development and use of dynamic experiments in wind tunnels from several of the NATO nations. They address current oscillatory and rotary test techniques, experimental results for typical configurations, and the use of these data for flight mechanics applications. Subject included are: dynamic lift, wing rock, fluid dynamics of rotary flows, mathematical modelling, non-linear data representation, vortex manipulation for control enhancement, and correlations of predictions based on rotary and oscillatory wind-tunnel and flight-test results. The complete course notes are contained in two volumes. The main part of the notes is contained in AGARD Advisory Report 265 (ADA235179). The present volume includes papers on: Unsteady aerodynamics of slender wings; Dynamic stall effects and applications to high performance aircraft; Oscillatory test techniques; Large amplitude oscillations; Oscillatory data for typical configurations; and Forebody vortex control."--Stinet.
