Successful start of 2D PIV measurements at LTU – now moving on to 3D PIV

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

PIV measurements at the LTU test rig are underway

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
