Large-eddy simulations(LES) is an attractive approach for the simulation of turbulent flows involving chemical reactions. Within LES, the large energy containing scales of motion, which are highly geometry dependent, are explicitly calculated. The smaller more universal scales of motion, however, are modeled using an appropriate subgrid model. Applying LES to reacting flows is difficult due to additional unclosed terms in the LES equations related to combustion processes. One approach for modeling these terms is to employ the linear-eddy mixing (LEM) model. This model separately treats the physical process of molecular diffusion and turbulent stirring at the small scales so that an accurate picture of the interaction of the turbulence and the chemistry can be obtained. Previous applications of the LEM model within LES have been for negligible heat release cases in which the chemistry can be uncoupled from the fluid dynamics. This paper describes the extension of the methodology to fully coupled simulations with heat release.
