Turbulent-combustion closure for the chemical source terms and molecular mixing using the linear-eddy model
Paper in proceeding, 2017

Turbulent combustion models approximate the interaction between turbulence, molecular transport and chemical reactions with the purpose of allowing computationally feasible simulations. There are many of these models and the present interest is on the lineareddy model (LEM). Specifically this paper introduces and tests a new method to use LEM to close the filtered chemical source terms in the conservation equations of the thermochemical quantities. For this purpose, this paper discusses the conceptual enhancements of this method over traditional LEM implementations, and its testing in a widely-used bluff-body-stabilized-flame problem.
