Prediction of Gas Turbine Combustor Performance Based on Optimal Reduced Kinetics and Dynamic Mode Decomposition

• In the gas turbine community the development of combustor technology is currently following the general trend towards fuel-flexibility. Fully detailed mechanisms for these fuels are expensive in terms of computer time when coupled with CFD, and the complexity of combustion chemistry must hence be downsized. The research field hence may be described as CFD modeling of unsteady combustor flows in the context of finite-rate kinetics and the use of such a tool for eigenmode extraction and analysis. The research includes refinement of optimized global multi-step mechanisms for several different fuels as well as improvement and evaluation of the Dynamic Mode Decomposition in practical combustor settings.
