A 3D-PTV demo of a weakly turbulent jet, with some air bubbles. The jet
is injected vertically upwards inside a glass tank full of water. The
water is seeded with tracer particles at a rather high seeding density.
The jet is weakly turbulent at a Reynolds number in the order of a few
hundred ~500, and a nozzle diameter of ~ 1cm. The flow is generated by a
peristaltic pump.
This dataset holds both raw data (images and binary "blob" files) that
can be used to generate Lagrangian tracer trajectories, and a segment of
post-processed data. Furthermore, there are videos and visualizations
of the processed data and raw videos of the experimental apparatus.
There is also a small number of python scripts that can help in the
processing. The data open for free use, under a humble request of citation.
