摘要: Abstract Flamelet Generated Manifolds (FGM) tabulated chemistry is used in combination with a thickened flame approach to perform Large Eddy Simulation (LES) of premixed combustion. Two-dimensional manifolds are describe the by mixture fraction and progress variable. Simulations one-dimensional flames have been verify coupling LES solver where important features like grid dependence propagation carefully addressed. Finally, method applied turbulent swirl burner including complex geometry nozzle. Results velocity, species temperature compared experimental data. Thereby different efficiency functions show sensitivity related this model parameter. Some aspects regarding dynamic thickening, numerical accuracy computational also
