Large eddy simulations of turbulent flame kernels
Large eddy simulations of turbulent flame kernels
A combustion LES code has been developed to investigate the effects of a premixed turbulent flame kernel. The code solves the fully compressible governing equations for mass, momentum, progress variable and energy on a structured Cartesian grid. Smagorinsky eddy viscosity model with dynamic procedure is used as a subgrid scale turbulence model. A flame surface density model based on the flamelet concept is employed on the subgrid scale reaction rate. Results from LES will be compared with existing DNS results, and investigations will be carried out on flame surface evolution statistics.

Abstract
A combustion LES code has been developed to investigate the effects of a premixed turbulent flame kernel. The code solves the fully compressible governing equations for mass, momentum, progress variable and energy on a structured Cartesian grid. Smagorinsky eddy viscosity model with dynamic procedure is used as a subgrid scale turbulence model. A flame surface density model based on the flamelet concept is employed on the subgrid scale reaction rate. Results from LES will be compared with existing DNS results, and investigations will be carried out on flame surface evolution statistics.
