The objective of this presentation is to give an overview of simulations made by a Large Eddy Simulation (LES) model. The LES model, founded on a physical model based on modern continuum mechanical mixture theories, includes a complete treatment of the sub grid stresses and fluxes accounting for both backscatter and outscatter. Results from numerical simulations of three combustion applications will be presented: the first configuration is a bluff body stabilized flame, the second is a pulse combustor and the third is a ramjet combustor. Results from the simulations are compared with available experimental measurements, for example temperature, constituent mass fraction and velocity fields. This comparison indicates that the LES technique works well for all investigated applications and that the simulation method mimics most of the significant flow features.
