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 below. When we have processed the data, we aim at presenting the results at the ISPIV conference that is held in the summer, says Joel Sundström from LTU.
In addition, we hope that we can correlate the measured velocity fields with pressure measurements that were performed simultaneously so that we can use the knowledge acquired from the PIV measurements for the cases that we don’t have any velocity data (Älvkarleby, Porjus, Oksla), Joel Sundström continues.
With the PIV measurements completed, the next step in the LTU test rig is to perform RVR mitigation using IPM. We are currently mounting the IPM system, so hopefully we can test the system during next week, Joel Sundström ends.
*In a previous news item, the stereoscopic measurements were termed 3 dimensional. Note that the stereoscopic measurement provides all three velocity components in a plane; hence the term 3 dimensional is somewhat vague and the phrasing three component two dimensional is perhaps more lucid.
