خلاصه مقاله:
Large Eddy Simulation (LES) with finite-rate/eddy dissipation combustion model is applied to simulate transient behavior of a three-stream jet-in-hot-coflow (JHC) flame. Two static SGS models including the Smagorinsky and WALE together with two dynamic SGS models comprising the dynamic Smagorinsky and dynamic kinetic energy have been investigated to resolve sub-grid scale stresses. It is shown that the dynamic SGS models, generally, gives improved accuracy over the static models. In particular, the dynamic procedure of assigning model parameters and non-equilibrium turbulence assumption in the dynamic kinetic energy model are the key factors leading to produce acceptable results for mean and fluctuating temperature fields
