Webinar: Three-dimensional measurements in flows
The Francophone Laser Velocimetry Association (AFVL) is organizing a joint day on the theme " Three-dimensional measurements in turbulent flows ". This 47th Thematic Day (JT47) took place on November 18, 2020, by videoconference.
In less than 10 years, the progress made in 3D measurements in turbulent flows is considerable. This day was an opportunity to discuss different aspects of these methods and their recent developments (equipment, reconstruction, precision, application domain, post-processing, etc.). Velocity measurements in turbulent flows were a focal point of this day, but 3D measurements for surface deformations or scalar (density) measurement were also discussed. This day brought together about forty participants in a video conference.
Date: 18 November 2020Link: https://www.afvl.fr/index.php/les-evenements/les-journees-afvl/138-47ieme-jtChallenge: The first challenges on Lagrangian Particle Tracking (LPT) and on Data Assimilation (DA) from LPT data
- Time-series, four-pulse- and two-pulse pairs of synthetic particle images with various ppp-values created by four virtual camera views of tracer particles in the TBL flow are provided together with the calibration data in order to challenge the latest LPT code developments.
- A large number of randomly distributed 3D particle tracks over many time-steps representing the flow are provided as starting points of a data assimilation challenge.
