Aeroacoustics and Aeroelastics of Turbomachinery

The event is organized and hosted by the Institute of Turbomachinery and Fluid Dynamics (TFD). Therefore, please pay attention to the event announcements at the TFD!

The lecture provides an introduction to the issues of aeroelastics and aeroacoustics in turbomachinery and other kind of machines, e.g. wind turbines. Effects relevant for the design and safe operation, such as flutter, forced vibrations, sound generation and transport, are the central topic of the lecture. On the one hand, the fundamentals necessary for understanding the interactions that occur between structure, flow and sound are taught. On the other hand, practical topics like possible procedures for the investigation of aeroelastic and aeroacoustic phenomena are dealt with. The lecture is aimed in particular at students with an interest in future-oriented, interdisciplinary issues in power engineering machines, such as aircraft engines, wind turbines, gas and steam turbines.
