摘要

Large eddy simulation (LES) of turbulent premixed combustion flows over backward facing step been performed by using Dynamic Subgrid G-equation flamelet model. A flamelet model for the premixed flame is combined with a dynamic subgrid combustion model for the filtered propagation flame speed. The objective of study is to investigate the validity of the dynamic subgrid G-equation model to a complex turbulent premixed combustion for the considering of the realistic engineering application.
The calculated results were compared with experimental results and good agreement is obtained.
