Abstract

Direct numerical simulation (DNS) of three-dimensional turbulent reacting channel flows with buoyancy is carried out using a spectral method. Statistical results from the DNS database are used to validate an algebraic second-order-moment sub-grid-scale (ASOM-SGS) combustion model and show that the ASOM-SGS model is reasonable. Furthermore, a methane-air jet flame is simulated by large-eddy simulation (LES) using the ASOMSGS model and indicates that the Reynolds-averaged Navier-Stokes ASOM combustion model is a reasonable model.
