Fundamental investigations into flow phenomena and interaction mechanisms in modern high-pressure turbines are carried out at the Large Scale Turbine Rig (LSTR). The focus is on a Reynolds-scaled high-pressure turbine rotor, which was scaled using a Mach-like high-pressure turbine test rig. Reynolds scaling offers decisive advantages for experimental investigations, but does not reproduce Mach number effects.

One of the main components of hydropower plants is the electrical generator converting mechanical to electrical energy. Despite the very high efficiency, dissipation occurs due to electromagnetic losses and must be removed from the system. For this purpose, a thermodynamic cycle is realized providing the required cooling air to the critical devices. A model of a hydro generator is currently in the design process, that will enable a detailed experimental analysis of the cooling flow.
