Large Eddy Simulation of a Gas Turbine Combustion chamber: effect of the subgrid scale flame thickness on the flame dynamics
A analysis of the subgrid scale flame thickness in the LES framework is presented. The influence of the subgrid flame thickness has been tested numerically on a swirl stabilized flame using a flamelet formulation. The analysis introduces a non-dimensional number a, characteristic for flame and the filter. The values of this number are computed for different LES combustion models and lie in a wide
