Computational resources have developed to the level that, for the first time, it is becoming possible to apply large-eddy simulation (LES) to turbulent flow problems of realistic complexity. Many examples can be found in technology and in a variety of natural flows. This puts issues related to assessing, assuring, and predicting the quality of LES into the spotlight. Several LES studies have been published in the past, demonstrating a high level of accuracy with which turbulent flow predictions can be attained, without having to resort to the excessive requirements on computational resources imposed by direct numerical simulations. However, the setup and use of turbulent flow simulations requires a profound knowledge of fluid mechanics, numerical techniques, and the application under consideration. The susceptibility of large-eddy simulations to errors in modelling, in numerics, and in the treatment of boundary conditions, can be quite large due to nonlinear accumulation of different contributions over time, leading to an intricate and unpredictable situation. A full understanding of the interacting error dynamics in large-eddy simulations is still lacking. To ensure the reliability of large-eddy simulations for a wide range of industrial users, the development of clear standards for the evaluation, prediction, and control of simulation errors in LES is summoned. The workshop on Quality and Reliability of Large-Eddy Simulations, held October 22-24, 2007 in Leuven, Belgium (QLES2007), provided one of the first platforms specifically addressing these aspects of LES.

A few years ago the Helmholtz Association (HGF) consisting of 15 research Institutions including the German Aerospace Center (DLR) started a network research program called 'Virtual Institutes'. The basic idea of this program was to establish research groups formed by Helmholtz research centers and universities to study and develop methods or technologies for future applications and educate young scientists. It should also enable and encourage the partners of this Virtual Institute after 3 years funding to continue their cooperation in other programs. Following this HGF request and chance the DLR Windtunnel Department of the Institute of Aerodynamics and Flow Technology took the initiative and established a network with other DLR institutes and German u- versities RWTH Aachen, University of Stuttgart and Technical University Munich. The main goal of this network was to share the experience in system analysis, ae- dynamics and material science for aerospace for improving the understanding and applicability of some key technologies for future reusable space transportation s- tems. Therefore, the virtual institute was named RESPACE (Key Technologies for Re- Usable Space Systems).

Fluid Power Circuits and Controls: Fundamentals and Applications, Second Edition, is designed for a first course in fluid power for undergraduate engineering students. After an introduction to the design and function of components, students apply what they've learned and consider how the component operating characteristics interact with the rest of the circuit. The Second Edition offers many new worked examples and additional exercises and problems in each chapter. Half of these new problems involve the basic analysis of specific elements, and the rest are design-oriented, emphasizing the analysis of system performance. The envisioned course does not require a controls course as a prerequisite; however, it does lay a foundation for understanding the extraordinary productivity and accuracy that can be achieved when control engineers and fluid power engineers work as a team on a fluid power design problem. A complete solutions manual is available for qualified adopting instructors.

Particle Image Velocimetry (PIV) is a non-intrusive optical measurement technique which allows capturing several thousand velocity vectors within large flow fields instantaneously. Today, the PIV technique has spread widely and differentiated into many distinct applications, from micro flows over combustion to supersonic flows for both industrial needs and research. Over the past decade the measurement technique and the hard- and software have been improved continuously so that PIV has become a reliable and accurate method for "real life" investigations. Nevertheless there is still an ongoing process of improvements and extensions of the PIV technique towards 3D, time resolution, higher accuracy, measurements under harsh conditions and micro- and macroscales. This book gives a synopsis of the main results achieved during the EC-funded network PivNet 2 as well as a survey of the state of the art of scientific research using PIV techniques in different fields of application.

This textbook presents a systematic study of the qualitative and geometric theory of nonlinear differential equations and dynamical systems. Although the main topic of the book is the local and global behavior of nonlinear systems and their bifurcations, a thorough treatment of linear systems is given at the beginning of the text. All the material necessary for a clear understanding of the qualitative behavior of dynamical systems is contained in this textbook, including an outline of the proof and examples illustrating the proof of the Hartman-Grobman theorem, the use of the Poincare map in the theory of limit cycles, the theory of rotated vector fields and its use in the study of limit cycles and homoclinic loops, and a description of the behavior and termination of one-parameter families of limit cycles. In addition to minor corrections and updates throughout, this new edition includes materials on higher order Melnikov theory and the bifurcation of limit cycles for planar systems of differential equations, including new sections on Francoise's algorithm for higher order Melnikov functions and on the finite codimension bifurcations that occur in the class of bounded quadratic systems.

This volume contains the proceedings of the IUTAM Symposium on Computational Physics and New Perspectives in Turbulence, held at Nagoya University, Nagoya, Japan, in September 2006. Leading experts in turbulence research were brought together at this Symposium to exchange ideas and discuss, in the light of the recent progress in computational methods, new perspectives in our understanding of turbulence. Special emphasis was given to fundamental aspects of the physics of turbulence. The subjects discussed here cover: computational physics and the theory of canonical turbulent flows; experimental approaches to fundamental problems in turbulence; turbulence modeling and numerical methods; and geophysical and astrophysical turbulence. This work should be useful to graduate students and researchers interested in fundamental aspects of turbulence.

The numerical optimization of practical applications has been an issue of major importance for the last 10 years. It allows us to explore reliable non-trivial configurations, differing widely from all known solutions. The purpose of this book is to introduce the state-of-the-art concerning this issue and many complementary applications are presented.

This successful textbook emphasizes the unified nature of all the disciplines of Fluid Mechanics as they emerge from the general principles of continuum mechanics. The different branches of Fluid Mechanics, always originating from simplifying assumptions, are developed according to the basic rule: from the general to the specific. The first part of the book contains a concise but readable introduction into kinematics and the formulation of the laws of mechanics and thermodynamics. The second part consists of the methodical application of these principles to technology. In addition, sections about thin-film flow and flow through porous media are included.

In this authoritative and comprehensive volume, Claude Bardos and Andrei Fursikov have drawn together an impressive array of international contributors to present important recent results and perspectives in this area. The main subjects that appear here relate largely to mathematical aspects of the theory but some novel schemes used in applied mathematics are also presented. Various topics from control theory, including Navier-Stokes equations, are covered.

This is a unique collection of papers, all written by leading specialists, that presents the most recent results and advances in stability theory as it relates to fluid flows. The stability property is of great interest for researchers in many fields, including mathematical analysis, theory of partial differential equations, optimal control, numerical analysis, and fluid mechanics. This text will be essential reading for many researchers working in these fields.

Many fundamental aspects of experimental research never appear in standard scientific reports, since writing space is limited in scientific journals. Often a researcher building a new experiment says: why they do not tell us this clearly ? This book is intended to introduce the experimental researchers, the screwdriver scientists, to state-of-the-art techniques in the study of the dynamics of complex liquids. In Time-Resolved Spectroscopy in Complex Liquids, the contributors concentrate on time-resolved optical spectroscopy, which recently produced many relevant results and new information about complex liquids. This is an emerging topic of soft-matter science, studying the innovative phenomena appearing in molecular liquids when a process of strong intermolecular interaction takes place. In the book, the contributors stress the experimental aspects, even the simple ones. This book succeeds in the full description of the experimental procedure, overcoming the often-ocurring break between introduction and the results discussion.

Thermal and flow processes are ubiquitous in mechanical, aerospace and chemical engineering systems. Experimental methods including thermal and flow diagnostics are therefore an important element in preparation of future engineers and researchers in this field. Due to the interdisciplinary nature of experimentation, a fundamental guidance book is essential in the engineering curriculum and as a technical reference. Thermal and Flow Measurements provides a synthesis of the basic science and engineering of diagnostic methods that students and engineers need to understand, design and apply to measurements in mechanical, aerospace and chemical engineering processes. A clear exposition is given on the basic concepts and application aspects of a wide range of thermal and flow diagnostics, starting from basic sensors, flow visualization, velocimetry, laser optical diagnostics, particle sizing methods, gas sampling methods, to micro-, nano-scale sensors and lidars. The presentation of topics allow readers to see the fundamental principles behind each methodology as well as the application details.

The book covers particle-based methods and also discusses Eulerian-Eulerian and Eulerian-Lagrangian techniques based on finite-volume schemes. Moreover, the possibility of modeling the poly-dispersity of the secondary phases in Eulerian-Eulerian schemes by solving the population balance equation is discussed.

This book deals with the mechanics of solid bodies in contact, a subject intimately connected with such topics as fracture, hardness, and elasticity. Coverage begins with an introduction to the mechanical properties of materials, general fracture mechanics, and the fracture of brittle solids. It then provides a detailed description of indentation stress fields for both elastic and elastic-plastic contact. In addition, the book discusses the formation of Hertzian cone cracks in brittle materials, subsurface damage in ductile materials, and the meaning of hardness. Coverage concludes with an overview of practical methods of indentation testing.

Today, fluid power systems, hydraulic and pneumatic, in alliance with advanced electronics, provide the world with an unprecedented array of applications and systems from heavy-lifting equipment to spray painting, injection moulding, motion control and product assembly. In common with other facets of modern industrial operation, fluid power systems must be examined with a view to obtaining:

• the highest product quality;
• optimised efficiency;
• improved safety;
• maximum profitability.

Modelling, Monitoring and Diagnostic Techniques for Fluid Power Systems covers the background theory of fluid power and indicates the range of concepts necessary for a modern approach to condition monitoring and fault diagnosis in a readable an understandable fashion. The theory is constantly leavened by 15-years-worth of practical measurements by the author, working in association with major fluid power companies, and real industrial case studies a" hot-strip-mill monitoring in conjunction with Corus p.l.c. being just one example.

The comprehensive reference for its subject, this book gives the first integrated exposition of the fluid power applications of many of the techniques it describes: time-encoded signal processing; artificial neural networks and expert systems among others. Advantages and limitations of the different paths are presented to emphasise that the reader should consider the gamut of methods leading to positive decision-making regarding fault diagnosis. Four parts combine to produce a thorough and all-embracing whole:

• an introduction to component behaviour;
• a guide to the modelling methods employed for circuitanalysis;
• methods for doing condition monitoring;
• common faults and breakdowns.

Modelling, Monitoring and Diagnostic Techniques for Fluid Power Systems tells practicing fluid power engineers all they need to know about keeping track of the "health" of their equipment, processes and products. With nearly four hundred references to provide a good overview of the subject and to stimulate further research, this reference will also be invaluable to graduate and senior undergraduate students entering the field.
