Rotordynamische Charakterisierung von Dichtungssystemen zur Anwendung in Kraftwerksdampfturbinen

As a significant part of the global electrical energy supply, all forms of turbomachinery are subject to continual optimization processes. A very effective method of increasing a turbine´s inner efficiency is the reduction of leakage losses by the use of advanced internal seal concepts. This work deals with the investigation of the influence of working conditions and seal design on rotordynamic stability on steam turbins rotor systems.
