About the Journal
Welcome to the collection of final two-page abstracts and full-length papers (author's choice about which to submit) for the 14th International Symposium on Particle Image Velocimetry (ISPIV21). Particle Image Velocimetry (PIV) is an advanced optical measurement technique for non-intrusive analysis of microscopic and macroscopic flow fields in transparent fluids with high resolution. Thanks to the enormous developments in recent years in the fields of lasers, light emitting diodes (LEDs), digital cameras, computer performance, memory capacity, and processing algorithms, very precise measurements are now possible in many research areas and the field of application is being continuously expanded. Due to its performance and efficiency, PIV is also increasingly used in industry to answer various research questions. The technique can be extended by complementary techniques (e.g. laser-induced fluorescence) to simultaneously measure scalars such as concentration, pressure and temperature. At the same time, the measured 2D or 3D flow fields can be used to determine physical quantities that cannot be measured with other techniques. The measurement technology thus provides deep insights into the flow phenomena, no matter how high the flow velocities are.
This biannual symposium series brings together leading PIV experts and users from all over the world to exchange and discuss the latest innovative developments and applications of the technology. The 14th edition of this symposium series was originally planned as an in-person meeting in Chicago, Illinois USA for August 1-4, 2021, following successful previous symposia in Munich (2019) and Busan (2017). However, owing to COVID-19 circumstances, it was moved to a virtual modality. In addition to these written contributions, authors also pre-recorded 15-minute presentations of their work that were shared with conference participants on demand. Finally, live keynote presentations were given by leading researchers in the PIV field: Prof. Yizheng Liu (Shanghai Jiao Tong University), Prof. Markus Raffel (German Aerospace Center, DLR), and Prof. Minami Yoda (Georgia Tech).
