PIV is an optical, mild intrusive measuring technique largely applied in many engineering fields to study and optimize fluid dynamic problems. Once a highly expensive tool, in the last years it has become a more accessible and diffuse technology in research facilities and industries thanks to the reduction of the costs of digital sensors (SCMOS) and laser sources.
The course will focus on the theoretical and practical aspects of the Particle Image Velocimetry including the theoretical background (such as geometrical and physical optics), the component selection criteria to optimize an experiment set-up and the post processing algorithms.
Application examples to real cases will be discussed, highlighting the actual peculiarities of setting up a PIV experiment for a given problem.
While the course will mainly focus on basics Set-Up as the 2D Mono and Stereo PIV, advanced techniques such as the Dual Pane, the Tomo-PIV and particle tracing techniques will be also introduced at the end of the course.
The course will end with and experimental activity that will involve the students in the main steps of a PIV experimental champaign such as: the cameras set-up, the calibration procedure, the acquisition and the application of pre and post-processing filter to the recordings.
