  • Aeroacoustic Scaling

Research Projects

Aeroacoustic scaling of turbine blade rows

To enable a more detailed experimental investigation of sound propagation in turbines, test rigs with acoustically optimized boundary conditions are necessary. For this purpose, the Institute of Turbomachinery and Fluid Dynamics operates an Aeroacoustic Wind Tunnel (AWT) to excite synthetic sound fields and investigate sound pressure levels within conditions corresponding to those of real machines. In particular, when local effects - such as sound propagation through individual blade rows - are of interest for the global behavior of a turbine, a turbine test rig is not suitable for precise aeroacoustic measurements due to sound reflections within the test rig. Consequently, the blade rows have to be scaled for an installation in the AWT and aeroacoustic similarity between the test rigs has to be established.
