DLR has to submit two deliverables in Workpackage 4. These contain several measurement techniques applied at a straight turbine cascade. The measurements are divided in two parts. This report includes measurements with and without cooling. The second part contains measurements with the former cooling configuration and air jet vortex generators (AJVG ́s), additionally. The second report will be delivered at the end of the project. The profile contour was designed by RRD and handed over at the beginning of the project. Besides do other partners numerical simulations for these flow cases. The following measurement techniques are applied: Schlieren technique, Infrared thermography, Hot-wire anemometry, Pressure tapping’s, Wake traverses. The hot-wire anemometry was deployed to investigate the inflow conditions. These results were already handed over to the partners, who adopt the numerical part, for their inlet boundary conditions. The measurements are utilized to compare them with the numerical results. This report is subdivided in the description of the wind tunnel system, the metrology, a subsequent chapter about uncertainties estimations and the presentation of the measurements will be done in the chapter Results and Discussion.
