Computations of a lean premixed methane - air flame in a lean stepped combustor are performed using a Delayed Detached Eddy Simulation approach to model turbulence. Two conditions for the outlet section are simulated and compared to an experimental database including mean velocity, mean temperature and instantaneous

* emission measurements. The main objective of this study is to assess of the efficiency of DDES for a massively separated reactive flow.
