Impact of Mixing on the Signature of Combustor Defects (A06*)

• Subject Area: Hydraulic and Turbo Engines and Piston Engines
• Term: from 2018 to 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 119193472

Combustor defects have an impact on the turbine performance and can be detected from the analysis of the exhaust gas pattern if the signature is sufficiently significant. Mixing processes reduce the information content, and impede the detection of defects in the exhaust path. In sub-project A6, possible combustor defects and the impact on the hot gas path will be simulated. The mixing processes will be analysed in detail on different laboratory burning chamber configurations with increasing complexity with experimental and numerical methods, such that a model approach for the complex turbulent mixing can be developed which will also be applicable to real jet engines.
