Sažetak
In this work large eddy simulation of two significantly different turbulent premixed flames, the highly stretched flame and the swirling flame, were performed in the framework of a SGS model based on coherent structures, the LES-CSM. The aim of this work is to show that the LES-CSM SGS model can be used as a general framework for modelling the turbulent transport in all varieties of laboratory-scale turbulent premixed flames. Both approaches, the one based on LES-CSM SGS model and standard Smagorinsky approach, are showing good agreement when comparing mean flame velocity and progress variable, but LES-CSM gives better representation of their variances.
