PIV data near hub of VT-400 axial turbine

Stereo Particle Image Velocimetry (PIV a standard method see e.g. https://link.springer.com/article/10.1007/s00348-005-0991-7) measurement inside an axial turbine VT-400 (see e.g. https://doi.org/10.1051/epjconf/201611402143). The measured area is oriented in axial × radial direction near the hub between the stator and rotor wheel. Therefore it covers the wake past stator wheel and secondary structures near the hub. Due to limited optical instrumentation, the data cover lot of surroundings, therefore a massive cut-off is needed (see the attached presentation "duda-ES2022.pptx" from conference PSE 2022). The main data are organized in the zip file "ExportedVectorFields.zip": there are 5 folders for studied regimes. Each contain several snapshots in form of csv table. It is a standard export from Dantec Dynamic Software, therefore it should be openable in TecPlot (But I have used my own codes to open, cut, filter and to calculate the mean characteristics). The overview can be found in the file "Figures.svg"; use Inkscape to open it and look around for all figures. Two attached movies show the opened turbine with laser alignment (no measuring during the movie) and a fog generator fogging into the inlet.
