Pulse Detonation Combustion at Gas Turbine Conditions (A01)

• Subject Area: Hydraulic and Turbo Engines and Piston Engines
• Term: from 2012 to 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 200291049

The pulse detonation combustor (PDC) multi tube test rig will be the central combustor for integration into the demonstrator. First, a turbine is attached to the PDC via a custom-made plenum to allow for investigations on the influence of operation parameters on the pressure fluctuations inside the plenum and the power generated by the turbine. To ensure efficient refilling of the combustion tubes as well as to minimize pressure fluctuations at the compressor outlet, a suited inlet geometry is designed and validated experimentally. Furthermore, the combustion efficiency inside the detonation front is determined to assess the potential of the PDC to increase the thermal efficiency of a gas turbine.
