Zusammenfassung:	In this work on-road flow measurement for automotive demands is implemented by means of a large-scale stereoscopic PIV, which was introduced by Sciacchitano et al. (2015) under the name Ring of Fire. In this work the whole wake region was investigated with a stereo camera configuration. The test vehicle was a Volkswagen up! traveling at a speed of 33.33 m/s, resulting in a Reynolds number of 3.30 ... In this work on-road flow measurement for automotive demands is implemented by means of a large-scale stereoscopic PIV, which was introduced by Sciacchitano et al. (2015) under the name Ring of Fire. In this work the whole wake region was investigated with a stereo camera configuration. The test vehicle was a Volkswagen up! traveling at a speed of 33.33 m/s, resulting in a Reynolds number of 3.30 x 106 based on the vehicle height. Measurements were acquired at a rate of 6 kHz with a measurement plane of approximately 2.8 x 2.2 m2. Time-resolved data was processed by means of cross correlation and the Shake-The-Box approach. Resulting non-dimensional, ensemble-averaged streamwise velocity fields of the wake compare well to literature and show that the on-road flow topologies of the wake can be resolved by both approaches.
