By adding Livia Pitorac to the team FDB strengthens the efforts for the upcoming field tests in the AFC4Hydro project. In her PhD work Livia gained valuable experience from power plants, and focused her thesis work on water conduit dynamics motivated by the increased demand for power ramping in the hydropower system. Such dynamics is …
The stereoscopic (i.e., three component two dimensional*) PIV measurements in the LTU test rig have now been finalized. In depth analyses of the acquired data is still underway, but comparisons with the previously performed purely two dimensional PIV measurements show great similarities with the two components that were measured then as seen in the figures …
The PIV measurements at LTU reaches their end – for this time Read More »

The 2D particle image velocimetry (PIV) measurements in the draft tube cone of the LTU test rig have now been finalized with successful outcome. Initial qualitative analyses show expected results, with two examples shown in the figures below. The figures display the axial velocity at the best efficiency point (BEP) to the left, and part load (PL) to the right (the dashed lines …
Successful start of 2D PIV measurements at LTU – now moving on to 3D PIV Read More »
As of last week, a particle image velocimetry (PIV) measurement system has been installed in the LTU test rig. Depending on the optical installation of the PIV system, measurements of either two or three velocity components in the draft tube cone will be performed in a plane passing through the center of the cone. The present optical installation has enabled measurements of two …

Watch our new video, where Prof Xavier Escaler, the project coordinator, gives an introduction to the AFC4Hydro project. AFC4Hydro is funded as a RIA project through the EU H2020 program. The project started June 2019, and is expected complete May 2023. Fig 1- Introduction by project coordinator Xavier Escaler About the video The video has …
On 18th of November 2020 the PhD candidate from UPC, Rafel Roig, participated in the first IAHR Young Professional Congress. He presented a numerical modal analysis of the Kaplan turbine in which the active flow control system will be tested next June. Fig 1 – Numerical Modal Analysis of kaplan turbine runner
The LTU test rig is now up and running, and the initial effort has been spent on performing efficiency measurements along with RVR characterization. “We are still working on the control system of the test rig together with FDB, but we are using a preliminary in-house control system at the moment so we can control …
