Local combined heat and power stations will gain importance as an efficient energy source in the near future. Gas Turbines, which have a rather simple design and low maintenance overheads, will be increasingly deployed for this task. In order to increase the efficiency without reducing the reliability, it is intended to apply ceramic materials for the rotor turbine and other relevant parts. Ceramic materials, if properly designed, will allow higher operating temperatures as encountered with biogenic fuels and decrease tip clearances, both leading to an increased effectiveness.
Fraunhofer SCAI accomplishes fluidmechanical, structural and coupled simulations to ensure operational stability of the ceramic rotor design. This comprises in detail:
