The Particle Image Velocimetry is undoubtedly one of the most important technique in Fluid-dynamics since it has a spatial character that allows to obtain a direct and instantaneous visualization of the flow field in a non-intrusive way. It represents the point of arrival of an intense research on the laser techniques and its origin dates back at the beginning of 80’s when Meynart, a doctoral student of the Von Karman Institute, while explorying the Laser Speckle Velocimetry technique, guessed the importance of capturing the movements of individual particles instead of speckles. The rising PIV technique immediately captured the scientific world interest but its spread was initially limited by. | THE PARTICLE IMAGE VELOCIMETRY -CHARACTERISTICS LIMITS AND POSSIBILE APPLICATIONS Edited by Giovanna Cavazzini THE PARTICLE IMAGE VELOCIMETRY -CHARACTERISTICS LIMITS AND POSSIBILE APPLICATIONS Edited by Giovanna Cavazzini The Particle Image Velocimetry - Characteristics Limits and Possibile Applications Edited by Giovanna Cavazzini Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2012 InTech All chapters are Open Access distributed under the Creative Commons Attribution license which allows users to download copy and build upon published articles even for commercial purposes as long as the author and publisher are properly credited which ensures maximum dissemination and a wider impact of our publications.
