Large Eddy Simulation of a Gas Turbine Combustion chamber: effect of the subgrid scale flame thickness on the flame dynamics
(2004) 5th International ERCOFTAC Workshop on Direct and Large-Eddy Simulation ERCOFTAC series ; 9. p.343-350- Abstract
- 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 range. The variations of the number a lead to completely different flame dynamics showing the importance of subgrid flame thickness modelling in the LES framework.
