Particle Image Velocimetry (PIV) has now matured as a versatile and robust tool for flow measurements. PIV is a technique able to measure instantaneous velocity fields in 2D and 3D domain at many points simultaneously, opening the path to field measurements of quantities such as vorticity and strain. The range of application in fluid dynamics research covers a wide spectrum, from microscopic to macroscopic scales of the atmospheric flows, from iposonic to hypersonic regime. The recent hardware and data-processing advances, especially in the fields of time-resolved PIV and volumetric Lagrangian Particle Tracking (LPT), have established PIV as a prominent technique in experimental fluid mechanics research and a must-have tool for top-class laboratories.

In recent years, PIV has undergone important changes, which have demonstrated the potential of further extending its reach. Leveraging physical principles opens the scenario to measuring thermodynamic variables and achieve a complete flow description. Blending with machine-learning techniques, low-order modelling and data-assimilation methods are also contributing to enriching the output of PIV measurements. To date, PIV is the most prominent candidate to become a complete flow measurement tool, capable to provide a complete flow description in terms of kinematic and thermodynamic variables.

The aim of this course is to discuss the fundamentals of the technique and initiate the attendees to the most recent developments in the field of PIV and LPT. The course will provide a complete overview of planar and volumetric PIV and LPT, including examples of application in a wide range of flows. A review of the state-of-art methods for data post-processing will also be included. The lectures will include practical examples with code writing of PIV image processing and data post-processing, with emphasis on the “human factor” in PIV image analysis and on the importance of robust algorithms to reduce measurement uncertainty. To this purpose, a PIV-interactive-session will be proposed, where the attendees will be invited to analyze images with their custom-made software or with open software available online.

The course is primarily directed to forthcoming PIV practitioners who wish to become expert users and/or developers of PIV. No previous knowledge is required besides basic understanding of fluid flows. The lecture series is currently organized as an online event. If the COVID situation will allow for it, the course will be given in both online and on-site format.

In this case, two visits and a laboratory demo will be organized on Wednesday and Thursday, as indicated in the course program, for the participants on site.

The lecture series will host a poster session, which will allow the participants to further exchange and interact with the lecturers. All the participants are encouraged to submit a 1-page abstract before 1 October 2021 to Ms. Evelyne Crochard, crochard@vki.ac.be.

This lecture series will take place online an on-site.
