Book excerpt: En mécanique des fluides, les mesures non intrusives sont fondamentales pour améliorer la connaissance du comportement des écoulements. Les cartes de vitesse, de température et de concentration, ainsi que la granulométrie des particules dans les écoulements diphasiques, permettent de mieux appréhender les phénomènes physiques, pour ensuite valider les codes de calculs. Les mesures de vitesse (ainsi que de températures et de concentrations de différentes espèces) par des techniques spectroscopiques reposant sur la diffusion des molécules sont bien adaptées à la caractérisation des écoulements rapides et réactifs , elles reposent sur la fluorescence induite par laser, la diffusion Raman Anti-Stokes cohérente ou l'emploi de diodes laser accordables. Dans les écoulements diphasiques, la détermination de la granulométrie des particules par des moyens optiques, ainsi que les principes de diffusion de la lumière sont détaillés. Pour chaque technique, les principes de base sont décrits, ainsi que les dispositifs optiques et de traitements des signaux. Les principales mesures de sécurité pour utiliser des sources laser intenses sont rappelées.

Download or read book Vélocimétrie laser pour la mécanique des fluides (Traité MIM, série Géomécanique ) written by BOUTIER Alain and published by Lavoisier. This book was released on 2012-06-01 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: En mécanique des fluides la mesure de la vitesse est fondamentale pour améliorer la connaissance du comportement de l'écoulement. Les cartes de vitesse d'un écoulement sont d'une aide précieuse pour en comprendre la structure moyenne et fluctuante, pour ensuite de valider les codes de calculs. La vélocimétrie laser est une technique optique de mesure des vitesses : elle est basée sur la diffusion de la lumière par de fines particules utilisées comme traceurs de l'écoulement, ce qui permet de déterminer la vitesse locale du fluide ainsi que ses fluctuations. Cet ouvrage présente les différentes techniques de vélocimétrie laser, ainsi que leurs spécificités : mesures locales ou dans un plan, mesures moyennes ou instantanées, mesures tridimensionnelles. L'ensemencement en particules des écoulements est décrit avec les produits couramment utilisés ainsi que les générateurs d'aérosols appropriés. Le post-traitement des données permet d'extraire une information synthétique des mesures et de se comparer aux prévisions issues des codes de calcul.
Book Synopsis Laser Metrology in Fluid Mechanics by : Alain Boutier
Download or read book Laser Metrology in Fluid Mechanics written by Alain Boutier and published by John Wiley & Sons. This book was released on 2013-02-20 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: In fluid mechanics, non-intrusive measurements are fundamental in order to improve knowledge of the behavior and main physical phenomena of flows in order to further validate codes. The principles and characteristics of the different techniques available in laser metrology are described in detail in this book. Velocity, temperature and concentration measurements by spectroscopic techniques based on light scattered by molecules are achieved by different techniques: laser-induced fluorescence, coherent anti-Stokes Raman scattering using lasers and parametric sources, and absorption spectroscopy by tunable laser diodes, which are generally better suited for high velocity flows. The size determination of particles by optical means, a technique mainly applied in two-phase flows, is the subject of another chapter, along with a description of the principles of light scattering. For each technique the basic principles are given, as well as optical devices and data processing. A final chapter reminds the reader of the main safety precautions to be taken when using powerful lasers.

Book excerpt: This volume includes revised and extended versions of selected papers presented at the Tenth International Symposium on Applications of Laser Techniques to Fluid Mechanics held at the Calouste Gulbenkian Foundation in Lisbon, during the period of July 10 to 13, 2000. The papers describe instrumentation developments for Velocity, Scalar and Multi-Phase Flows and results of measurements of Turbulent Flows, and Combustion and Engines. The papers demonstrate the continuing and healthy interest in the development of understanding of new methodologies and implementation in terms of new instrumentation. The prime objective of the Tenth Symposium was to provide a forum for the presentation of the most advanced research on laser techniques for flow measurements, and communicate significant results to fluid mechanics. The application of laser techniques to scientific and engineering fluid flow research was emphasized, but contributions to the theory and practice of laser methods were also considered where they facilitate new improved fluid mechanic research. Attention was placed on laser-Doppler anemometry, particle sizing and other methods for the measurement of velocity and scalars, such as particle image velocimetry and laser induced fluorescence.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of two decades of research work which started with an accidental observation. One of my students, Dipl. phys. Volkmar Lenz, - ticed that the speckle pattern of laser light scattered by a cuvette containing diluted milk performed a strange motion every time he came near the cuvette with his thumb. After thinkingabout this e?ect we came to the conclusion that this motion can only be caused by scatteringparticles with di?erent velocities, as in the case of the di?raction pattern of an optical grating: A linear motion of the grating does not change the pattern whereas a rotation of the grating does. The observed speckle motion could then be explained qualitatively as produced by the inhomogeneous velocity of the convection within the cuvette which was produced by the heat of the thumb. The theoretical treatment of this e?ect revealed that the velocity gradient of the light scattering medium is responsible for the speckle motion. The idea to use this e?ect for developingmeasurement techniques for velocity gradients arose almost immediately. For that purpose we had to develop not only experimental set-ups to measure the pattern velocity but also the theory which describes the connection between this velocity and the velocity gradient. The result of this work together with the description of a method developed by another group forms the contents of this book. I am indebted to the students who worked in my laboratory and developed the measurement techniques. These were, in temporal order, Dr.

Book Synopsis Laser Systems in Flow Measurement by : Tariq Durrani
Download or read book Laser Systems in Flow Measurement written by Tariq Durrani and published by Springer. This book was released on 1977 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now well established that laser flow-measuring systems have important advantages over more conventional techniques both for industrial and laboratory applications. These fundamental advantages are indicated by the enormous research effort which has gone into their development over the last decade and by the number of commercial systems which have become available. Although the field is still developing, the most important theoretical results required for relating the system outputs to the fluid flow parameters have now been formulated and a book on the subject therefore seems timely. In the text we have tried to collect together the most important results both from our own papers and from publications by other authors and to present these in a concise and easily readable form. Emphasis has been placed on the fundamental theory and limitations associated with the various techniques rather than on detailed description of specific systems. We have also included a number of new results on areas such as photon counting in turbulent and periodic flows, frequency domain and time domain analysis of laser Doppler velocimeter signals, effect of background noise on system performance, and on cross-correlation techniques for diffusing flows.

Available in PDF, EPUB and Kindle. Book excerpt: For this sixth volume 01 proceedings stemming lrom a Symposium on the Applications 01 Laser Techniques to Fluid Techniques, we have selected thirty one papers which are presented in live chapters. They represent some 01 the best papers presented at the Sixth Symposium which was again held at the Calouste Gulbenkian Foundation in Lisbon, this time lrom 20 to 23 July 1992. The total number of papers at the Symposium was slightly larger than in 1990 and was selected from a much increased number of abstracts, with a considerably smaller of accepted manuscripts. Thus, this volume represents some 01 the best 01 the best. The topics we have chosen to include are Laser Anemometer Optics and Processing, Two-Phase Flow Instrumentation, Whole-Field Velocimetry, Complex Flow Applications and Engine and Combusting Flows, and they show that there continues to be a healthy interest in the development 01 understanding of the methodology and its implementation in terms 01 new instrumentation, and this is emphasised by the increasing number 01 companies which have attended the Symposium in recent years in order to demonstrate their range 01 products. At the same time, it is clear that there is an increasing range of applications 01 the corresponding laser techniques and this is represented, in part, by the chapters concerned with Complex and Engine and Combusting Flows. In general, we are very pleased with the way the application 01 laser techniques has grown and hope that this se ries 01 Symposia has played its part.
