Blade Vibrations in Turbines
In the report it will be shown, which facts have to be considered for the turbine-manufacturer in the design process regarding blade vibrations. Of importance for the operator is a smooth operation of the steam turbines with a permissible state of blade vibrations. To control the actual state, blade vibrations can be measured during operation (Monitoring). By such measurements indications can be obtained about possible failure mechanisms. Vibration Standards help for an evaluation of the blade vibrations.

Cavitation induced vibrations in orifice plates and a partially closed valve
This study aims to experimentally investigate flow-induced vibrations and cavitation in single-hole and multi-hole orifices and a partially closed Stafsjö valve. The goal is to provide experimental data for validating Computational Fluid Dynamics (CFD) models.
