LARGE EDDY SIMULATION OF A NON-PREMIXED TURBULENT BURNER USING A DYNAMICALLY THICKENED FLAME MODEL

摘要

A new LES subgrid scale turbulent combustion model, adapted to combustion regimes which are nor perfectly prernixed or non-premixed, is tested in a simplified configuration. This model does not require any a priori assumption on the flame structure and is able to compute flows where both prernixed and non-premixed flamelets coexist. Three combustion regimes are successfully recovered in numerical simulations.
