Turbine

Head: Prof. Dr. Ingo Röhle

Flow visualization on Turbine rotor

A turbine is most effective to convert fluid energy to mechanical energy.
In turbomachines used in power plants (gas and steam turbines) as well as in aircraft propulsion, the turbine utilizes the fluid energy to drive a compressor or fan or it generates electricity by directly driving an electric generator.

The Turbine Department, located in Göttingen, but part of the Institute of Propulsion Technology, is responsible for research in turbine flow.
In close cooperation with industry research is carried out with respect to performance improvement and increase of specific power of turbines and investigations concerning heat transfer and cooling effectiveness.

Current Projects 

The Turbine Department is involved in European and national research projects on turbomachines, esp. Turbine Aerodynamics, Thermodynamics and in investigations of turbine blade performance as a service for industrial partners. Current projects are listed below:

• Investigation  of HP Turbine Stages with combustor simulator:
  OmniTurb, INTERTURB (LuFo IV national program).
• EU project FACTOR
• EU project TFAST
• Aerothermal investigation of Turbines (Project HEAT)
• Aerodynamic design and optimization of turbine stages
• Participation at the Collaborative Research Centre SFB 871 named "Product Regeneration".
• Investigation of a gas turbine exhaust diffusor

Completed Projects

• Liner Heat Transfer in an HP Turbine Stage (AG TURBO-TURBOTECH II)
• High Pressure Turbine Forced Response
  Brite-EuRam Project: ADTurBII (Aeroelastic Design of Turbine Blades)
• Aerothermal Investigations on Turbine Endwalls and Blades
  Brite-EuRam Project: AITEB-2 (Aerothermal Investigations on Turbine Endwalls and Blades)
