AB  - Large  eddy  simulation  (LES)  of  a  partially  pre-mixed,  swirl-stabilised  flame  is  performed  using  atransported  Probability  Density  Function  approachsolved  by  the  stochastic  fields  method  to  accountfor  turbulence-chemistry  interaction  on  the  sub-gridscales. The corresponding sub-grid stresses and scalarfluxes  are  modelled  via  a  dynamic  version  of  theSmagorinsky model and a gradient diffusion approx-imation,  respectively.A  15-step  reduced  methanemechanism including 19 species is employed for thedescription of all chemical reactions. The test case in-volves a widely studied gas turbine model combustorwith complex geometry and the simulation is carriedout for a specific operating condition involving an os-cillating flame. Overall, results of the velocity, temper-ature and major species mass fractions as well as theinstantaneous thermochemical properties are shown tobe in good agreement with experimental data, demon-strating the capabilities of the applied stochastic fieldsmethod. The inclusion of wall heat transfer in the com-bustion chamber is found to improve temperature pre-dictions, especially in the near-wall regions.  In sum-mary, this work showcases the LES method’s accuracyand robustness - none of the default model parametersare adjusted - for an application to complex, partiallypremixed combustion problems
