A conditional moment closure model is adopted together with a state-of- the-art LES approach to simulate the target flame of the TNF workshop, Delft piloted methane flame III. For modeling the sub-grid scales, the constant Smagorinky model and the Dynamic Wale model are used in this study. First order conditional moment closure is used to model the turbulence-chemistry interaction. To calculate the conditional velocity, conditional volume averaging with smoothing is used. Two different models are used for computing the conditional scalar dissipation. One is the same procedure for the calculating conditional velocity i.e., volume averaging, and the other is to use Amplitude Mapping Closure model. A second order time accurate predictor-corrector method is used for time integration of the Favre filtered Navier-Stokes equations.
