A thickened flame model for large eddy simulations of turbulent premixed combustion
TL;DR: In this article, a subgrid scale model for large eddy simulations of turbulent premixed combustion is developed and validated, based on the concept of artificially thickened flames, keeping constant the laminar flame speed sl 0.

A power-law flame wrinkling model for LES of premixed turbulent combustion Part I: non-dynamic formulation and initial tests
TL;DR: In this article, a model of turbulent sub-grid scale flame speed for premixed combustion is proposed and tested in Large Eddy Simulation (LES), based on writing the unresolved flame surface density in terms of a general power-law expression that involves an inner cutoff scale.

TL;DR: In this article, large-eddy simulations of an industrial gas turbine burner are carried out for both nonreacting and reacting flow using a compressible unstructured solver, and results demonstrate the capacity of the LES to predict the mean flow, with and without combustion, as well as its main unstable modes: it is shown, for example, that the PVC mode is very strong for the cold flow but disappears with combustion.

Stretching and quenching of flamelets in premixed turbulent combustion
Charles Meneveau,Thierry Poinsot +1 more
TL;DR: In this article, the stretch rate of flamelets in premixed turbulent combustion is computed using detailed numerical simulations of vortex-flame interactions and a model for intermittent turbulence taking into account all possible turbulence scales acting on the flame front.
