Advanced Measurement Techniques Used in the Joined Measurement Campaign
A joint measurement campaign has been performed by the MARS project partners NUAA, CNRS (Poitiers) and DLR. The objective was to apply advanced measurement techniques to the actuator types which turned out to be most promising in the previous investigations. The selected devices were synthetic jet actuators from NUAA and plasma actuators from CNRS. Both actuator types were investigated in a backward facing step (BFS) geometry. Additional measurements took place using the synthetic jet actuator in a NACA-0015 profile from NUAA. For the measurements, a tomographic PIV and a long-distance microscopic stereo PIV measurement system—both capable to provide time-resolved data—have been set up by DLR in the one meter wind tunnel (1MG) at DLR Göttingen. The successful completion of this intercontinental experimental cooperation provides results which are a valuable data base for comparison with and validation of numerical methods.
