Abstract

The direct numerical simulation (DNS) of three-dimensional channel turbulent reacting flows with buoyancy force using a spectral method was carried out. The statistical DNS results are used to validate the second order moment sub-grid scale (SOM-SGS) turbulent combustion model. The results show that the SOM-SGS model is reasonable. Furthermore, a methane air jet flame was simulated by large eddy simulation (LES) using the SOM-SGS model. Additionally the LES statistical results show the reasonability of the RANS algebra SOM (ASOM) combustion model.
