The Eulerian stochastic field method is applied to solve the subgrid Probability Density Function (PDF) accounting for turbulence-chemistry interaction in the Large Eddy Simulation (LES) of a swirl stabilised gas turbine model combustor. A dynamic version of the Smagorinsky model for the subgrid scale stresses and a gradient diffusion approximation for the scalar fluxes complete the formulation. The chemical reaction is described by a 15-step reduced CH4 mechanism involving 19 species. Velocity, temperature and species results as well as basic thermochemical properties are shown to be in good agreement with experimental data validating the capabilities of the employed LES method.
