Part of the Fluid Mechanics and its Applications book series (FMIA, volume 54)


A subgrid combustion model is used to simulate premixed planar flames stabilized by stagnating flows and a confined swirl stabilized flame in an engineering combustor. Flamelet type combustion is assumed for both types of flames and experimental conditions are used for the simulations. The geometric characteristics of the flame surfaces and their effects on fluid dynamics are well predicted for the former type of flames. For the combustor simulation, the qualitative effects of heat release on the flow field are captured. The turbulence predictions in the combustor is highly sensitive to the characteristics of inflow turbulence. The turbulence modeling capability needs to be improved in order to better test the model in this case.
