A detailed presentation of the cooperative research activity undertaken by 20 European teams to contribute to the development of particle image velocimetry. This research was performed over a period of two years, in the frame of a European Brite-Euram contract and was greatly enhanced by its cooperative aspect. This text presents extensive comparisons of both recording and analysis of PIV images. A database has been built, which is presented in detail and which is accessible via the Internet. Industrial application in a large wind tunnel, validation of up-to-date numerical predictions and new developments including extension to 3C are also addressed in the different chapters of this book. In addition, 25 individual contributions are provided in the form of scientific papers which cover various aspects of the development of the method (PTV, video recording, stereo-PIV, holo-PIV). The study should be of interest to scientists and engineers active in the field.

This practical guide provides comprehensive information on PIV. The third edition extends many aspects of Particle image Velocimetry, in particular the tomographic PIV method, high-velocity PIV, Micro-PIV, and accuracy assessment.

The Particle Image Velocimetry (PIV) measurement technique has undergone a strong development in the last 10 years. This book presents the proceedings of an international workshop held in Zaragoza, Spain, on March 31st and April 1st, 2003, containing contributions from worldwide leading teams in the development of the PIV method. Most of these papers have been funded by the EC via the European EUROPIV 2 consortium to improve the performances of this measurement technique toward applications in the European Aeronautical industry, including results which are of strong interest for the worldwide community in Fluid Dynamics.

The book presents a synopsis of the main results achieved during the 3 year EU-project "Advanced Inflight Measurement Techniques (AIM)" which applied advanced image based measurement techniques to industrial flight testing. The book is intended to be not only an overview on the AIM activities but also a guide on the application of advanced optical measurement techniques for future flight testing. Furthermore it is a useful guide for engineers in the field of experimental methods and flight testing who face the challenge of a future requirement for the development of highly accurate non-intrusive in-flight measurement techniques.

The development of Particle Image Velocimetry (PIV), a measurement technique, which allows for capturing velocity information of whole ?ow ?elds in fractions of a second, has begun in the eighties of the last century. In 1998, when this book has been published ?rstly, the PIV technique emerged from laboratories to applications in fundamental and industrial research, in par- lel to the transition from photo-graphicalto video recording techniques. Thus this book, whose objective was and is to serve as a practical guide to the PIV technique, found strong interest within the increasing group of users. The early progress made with the PIV technique might best be char- terized by the experience gained during our aerodynamic research at DLR (Deutsches Zentrum fur ¨ Luft- und Raumfahrt) at that time. The ?rst app- cations of PIV outside the laboratory, in wind tunnels, as performed in the mid-eighties were characterized by the following time scales: time required to set up the system and to obtain well focused photo-graphical PIV recordings was 2 to 3 days, time required to process the ?lm was 0. 5 to 1 day, time - quired to evaluate a single photo-graphicalPIV recording by means of optical evaluation methods was 24 to 48 hours. When the ?rst edition of this book was published in 1998, with electronic cameras and computers, it was pos- ble to focus on-line, to capture several recordings per second, and to evaluate a digital recording within seconds.
