“…For a narrower field of view and/or reduced spatial resolution, this same setup can be used with a camera frame rate of 200 kHz to produce PIV data up to 100 kHz. PETAL's custom-built burst-mode laser systems [9] have successfully produced PIV data up to 1 MHz [10] in other experiments. With the region of interest being in the middle of the vane passage, there are no measurements from physical instruments such as hot wire anemometers or pitot-static probes that can be used for direct comparison with the PIV results.…”

“…A comprehensive review of recent PIV measurements in rotating turbomachinery applications was performed by Woisetschläger and Göttlich [9], with a special focus on the facilities at Graz University of Technology and at German Aerospace Center DLR. The transonic test turbine facility at Graz University features 24 stator and 36 rotor blades rotating at 10,600 rpm, while the centrifugal compressor at German Aerospace DLR features 13 main and 13 splitter blades rotating at up to 50,000 rpm.…”

“…The first derivative of the position with respect to the time is the velocity, which is of outstanding importance for instance in the understanding and characterization of fluid mechanics including the riddle of turbulence [8]. Current reviews for micro fluidic flow measurements [9] and meso-and macroscopic optical flow velocity field measurements based on Mie scattering [10] illustrate the huge application potential, e.g., for aerodynamic studies in turbomachinery [11,12], for thermoacoustic phenomena in flame flows [13,14], for transient two-phase flow phenomena in fast fuel injections shorter than one millisecond [15,16]. Further flows of interest are large scale flows such as occurring on the sun surface with velocity fluctuations up to ±1000 m/s [17] or small scale flows in micro channels in the order of mm/s [18].…”

“…Woisetschläger and Göttlich [28] provide an in-depth discussion on the application of PIV to the study of turbomachinery fluid dynamics. CO2 PLIF and VV require the same basic configuration as standard PIV techniques: a system for seeding the flow with trace GTP-19-1552 Sangan particles; a means of introducing the laser to the test region; and windows to provide a view of the illuminated flow to the cameras.…”
