Probability density function (PDF) and filtered density function (FDF)methodologies are developed and implemented, respectively, forReynolds-averaged Navier-Stokes (RANS) and large eddy simulation (LES) ofturbulent premixed flames. RANS predictions are made of a lean premixedbluff-body flame via the joint velocity-scalar-frequency PDF model. LES of apremixed Bunsen-burner flame is conducted via the scalar FDF methodology. Bothsimulations employ finite rate kinetics via a reduced methane chemistrymechanism to account for combustion. Prediction results are compared withexperimental data, and are shown to capture some of the intricate physics ofturbulent premixed combustion.
