A new computational methodology, termed "irregularly portioned Lagrangian Monte Carlo-finite difference" (IPLMCFD), is developed for large eddy simulation (LES) of turbulent combustion via the filtered density FDF). This is a hybrid methodology which couples a Monte Carlo FDF simulator with a structured Eulerian finite difference LES solver. The IPLMCFD is scalable to thousands of processors; thus it is suited for simulation of complex reactive flows. The scalability and consistency of the hybrid solver and the realizability and reliability of the generated results are demonstrated via LES of several turbulent flames under both nonpremixed and premixed conditions.
