*** General introduction ***
The dataset in this repository complements the publication: Grille Guerra, A., Scarano, F. & Sciacchitano, A. 
On the scalability of helium-filled soap bubbles for volumetric PIV. Exp Fluids 65, 23 (2024). 
https://doi.org/10.1007/s00348-024-03760-w. 

It is being made public both to act as supplementary data for the publication 
and in order for other researchers to use this data in their own work.

*** Experimental procedures ***
The data was collected in the High Speed Laboratories of the Faculty of Aerospace Engineering
of the Delft University of Technology between October 2022 and February 2023.

The bubble generator was 3D printed in-house, and the geometry is made publicly available in this repository 
(Online_resource_3.zip).

Bubbles were illuminated using a 2000 lumen commercial LED unit and images were taken with a 
Photron Fastcam SA1.1 high-speed camera.

*** Description of the data ***
The dataset contains the electronic supplementary material also available in the online version of the journal 
(two videos and a zipped file with the CAD geometry of the nozzle generator) 
and a digital version of the figures of the publication containing experimental data in Matlab figure format.
