Comparison of OpenPIV and PIVlab

Image
Since quite a while, I benefit from discussions with the main developer of OpenPIV (Prof. Alex Liberzon  from Tel Aviv University) and other people that contribute to OpenPIV. It is almost a bit like a cooperation, as we share thoughts on different topics, and Alex is really into practical and theoretical PIV application. I think we have a very friendly rivalry in developing useful PIV software. The results are available here:  https://github.com/alexlib/openpiv_pivlab_von_Karman_data You will notice that they are very noisy. But we intentionally decided to make the analysis very challenging for our software. The final interrogation area is e.g. only 6*6 pixels, and no smoothing is allowed. I don't really see a difference between OpenPIV and PIVlab, which is probably a good sign. It might be interesting to include commercial software too in this comparison in the future. By the way: Happy New Year to all PIVlab users (and of course all OpenPIV users too ;-D). The year 2020 has been

Free jet with 4 mm diameter: PIV test

Image
PIVlab's acquisition module can now also control our wireless custom mini seeding generator (all hardware available through OPTOLUTION.com ). That means that a single button click in PIVlab starts the whole measurement. I could add more remote controlled devices to control other hardware via PIVlab too (e.g. start a motor, open a valve, or whatever). Here, I wanted to measure the flow velocity at the exit of the wireless mini seeding generator. Example images can be found below. The field of view in this experiment was about 11 * 9 mm, and the pipe is D6, d4 mm.
