摘要：
Flameless combustion is a very promising technology for the future gas turbines. It is clean and stable-without large oscillations, noise and flashback. To facilitate the adoption of this technology in gas turbines, advanced design tools are needed. In this paper, a recently developed unsupervised post-processing tool is used to analyze the large amount of high-dimensional data produced in a series of Large Eddy Simulations (LES) of a model gas turbine operating in flameless mode. Simulations are performed using Finite Rate Chemistry (FRC) combustion modeling and a detailed description of chemistry. The automatic post-processing reveals important features of the combustion process that are not easily recognizable by other methods, making it a complementary step for the already established FRC-LES approach, and a potential design tool for advanced combustion systems.
