Unsteady flow data from the transonic test turbine obtained by Laser-Doppler-Velocimetry: 

Experimental investigations in transonic turbines have been performed at the Institute for Thermal Turbomachinery and Machine Dynamics over the last five years. The experimental data and the stage geometry are offered to the scientific community in order to support the understanding of unsteady three-dimensional transonic flow through cooperative CFD simulation.

The data focuses on unsteady flow phenomena in transonic turbines (stator-rotor interaction). It has been recorded at Technical University Graz within the framework of program Y-57 TEC, funded by the Austrian Science Foundation and the Austrian Ministry for Transport, Innovation and Technology. If you use these data, please make sure to acknowledge the TU Graz and cite the following publication:
