DLR Flow Field Measurements - European Research Project AITEB -

Kurzfassung

This report documents results from flow field measurements at the new DLR cascade test rig which was designed and built up for experimental investigations within work package 3 of the framework V project AITEB. The cascade represents the tip region of shrouded nozzle guide vanes with the additional presence of leakage effects. Results from surface pressure measurements, oil flow visualization, probe traverses and particle image velocimetry with varying leakage gap geometries, leakage blowing rates and low and high inlet turbulence intensities are described and discussed in detail.
