Book Description
The instability of fluid flows is a key topic in classical fluid mechanics because it has huge repercussions for applied disciplines such as chemical engineering, hydraulics, aeronautics, and geophysics. This modern introduction is written for any student, researcher, or practitioner working in the area, for whom an understanding of hydrodynamic instabilities is essential. Based on a decade's experience of teaching postgraduate students in fluid dynamics, this book brings the subject to life by emphasizing the physical mechanisms involved. The theory of dynamical systems provides the basic structure of the exposition, together with asymptotic methods. Wherever possible, Charru discusses the phenomena in terms of characteristic scales and dimensional analysis. The book includes numerous experimental studies, with references to videos and multimedia material, as well as over 150 exercises which introduce the reader to new problems.

Book Description
This book presents five sets of pedagogical lectures by internationally respected researchers on nonlinear instabilities and the transition to turbulence in hydrodynamics. The book begins with a general introduction to hydrodynamics covering fluid properties, flow measurement, dimensional analysis and turbulence. Chapter two reviews the special characteristics of instabilities in open flows. Chapter three presents mathematical tools for multiscale analysis and asymptotic matching applied to the dynamics of fronts and localized nonlinear states. Chapter four gives a detailed review of pattern forming instabilities. The final chapter provides a detailed and comprehensive introduction to the instability of flames, shocks and detonations. Together, these lectures provide a thought-provoking overview of current research in this important area.

The foremost authorities in cardiac anesthesia cover topics particular to this specialized field, such as extracorporeal circulation, transesophageal echocardiography, the physiology and pharmacology of anticoagulation, cardiac catheterization, invasive cardiology, and congenital heart disease. Ideal for residents, fellows, and practicing anesthesiologists, this important text provides comprehensive, practical guidance for all aspects of cardiac anesthesia.
Book Description
Turbulence est un livre d’initiation au monde fascinant de la turbulence dans les fluides au sens général : l’eau des rivières et des océans, l’air dans le sillage des véhicules aériens ou terrestres, les granulations solaires, la tache rouge de Jupiter... On y rencontre aussi bien l’imprévisibilité introduite par Henri Poincaré que l’effet papillon du météorologue Edouard Lorenz. Le lecteur comprendra mieux la trainée aérodynamique et la diffusion des polluants dans l’environnement, ou encore les instabilités qui dégénèrent en tourbillons cohérents. Les résultats récents sont présentés et l’auteur propose même des apports sur les écoulements des fluides biologiques ou sur le défi de la turbulence pour les modèles météorologiques et climatiques.L’objectif de l’ouvrage est de faire comprendre les concepts et de présenter des résultats sans équations dans un domaine où il est aisé de remplir un livre de formules mathématiques. L’accent est mis fortement sur les résultats de simulations numériques. Malgré la difficulté du sujet, le style clair et précis permet une lecture agréable et on se surprend à réfléchir sur le concept de turbulence en biologie, histoire et philosophie.Ce livre s’adresse à un public scientifique de niveau master (en mécanique, physique, mathématiques) et bien sûr aux universitaires, chercheurs, enseignants et au public cultivé de ce niveau.Polytechnicien, Marcel Lesieur est professeur émérite de Grenoble Institut National Polytechnique. Il a créé un groupe pionnier dans l’utilisation du calcul scientifique pour la modélisation et la simulation de la turbulence. Auteur de multiples publications, il a oeuvré dans les grands laboratoires mondiaux, à l’USC Los Angeles, Stanford, au NCAR Boulder du Colorado... Membre senior de l’Institut Universitaire de France puis membre de l’Académie des sciences, il offre dans cet ouvrage un aperçu de sa passion pour la turbulence et nous fait bénéficier de ses grandes qualités pédagogiques.

Book Description
obtained are still severely limited to low Reynolds numbers (about only one decade better than direct numerical simulations), and the interpretation of such calculations for complex, curved geometries is still unclear. It is evident that a lot of work (and a very significant increase in available computing power) is required before such methods can be adopted in daily's engineering practice. I hope to l"Cport on all these topics in a near future. The book is divided into six chapters, each· chapter in subchapters, sections and subsections. The first part is introduced by Chapter 1 which summarizes the equations of fluid mechanies, it is developed in C~apters 2 to 4 devoted to the construction of turbulence models. What has been called "engineering methods" is considered in Chapter 2 where the Reynolds averaged equations al"C established and the closure problem studied (§1-3). A first detailed study of homogeneous turbulent flows follows (§4). It includes a review of available experimental data and their modeling. The eddy viscosity concept is analyzed in §5 with the l"Csulting ~alar-transport equation models such as the famous K-e model. Reynolds stl"Css models (Chapter 4) require a preliminary consideration of two-point turbulence concepts which are developed in Chapter 3 devoted to homogeneous turbulence. We review the two-point moments of velocity fields and their spectral transforms (§ 1), their general dynamics (§2) with the particular case of homogeneous, isotropie turbulence (§3) whel"C the so-called Kolmogorov's assumptions are discussed at length.

Book Description
This book covers the major problems of turbulence and turbulent processes, including physical phenomena, their modeling and their simulation. After a general introduction in Chapter 1 illustrating many aspects dealing with turbulent flows, averaged equations and kinetic energy budgets are provided in Chapter 2. The concept of turbulent viscosity as a closure of the Reynolds stress is also introduced. Wall-bounded flows are presented in Chapter 3 and aspects specific to boundary layers and channel or pipe flows are also pointed out. Free shear flows, namely free jets and wakes, are considered in Chapter 4. Chapter 5 deals with vortex dynamics. Homogeneous turbulence, isotropy and dynamics of isotropic turbulence are presented in Chapters 6 and 7. Turbulence is then described both in the physical space and in the wave number space. Time dependent numerical simulations are presented in Chapter 8, where an introduction to large eddy simulation is offered. The last three chapters of the book summarize remarkable digital techniques current and experimental. Many results are presented in a practical way, based on both experiments and numerical simulations. The book is written for a advanced engineering students as well as postgraduate engineers and researchers. For students, it contains the essential results as well as details and demonstrations whose oral transmission is often tedious. At a more advanced level, the text provides numerous references which allow readers to find quickly further study regarding their work and to acquire a deeper knowledge on topics of interest.
