Large eddy simulation (LES) is a promising tool for numerical simulations of reacting flows, especially when combustion instabilities are encountered. In a first step toward prediction of such instabilities, LES of acoustically excited turbulent premixed flames is performed using a thickened flame a
A combined experimental and large eddy simulation (LES) study of flame kernel growth in isotropic, homogenous turbulence has been carried out. LES calculations using the combustion methodology of Weller were compared with experimental measurements from a fan-stirred bomb for iso-octane and propane a
The flame surface density approach to the modeling of premixed turbulent combustion is well established in the context of Reynolds-averaged simulations. For the future, it is necessary to consider large-eddy simulation (LES), which is likely to offer major advantages in terms of physical accuracy, p
The behaviour of a premixed turbulent ame is numerically studied in this paper. The numerical model is based on solving turbulent ow ΓΏeld by the discrete vortex method. The ame is considered to be of zero thickness boundary which separates burnt and unburnt regions with di erent constant density and
