- Large Eddy Simulation (LES); Reynolds-Averaged Navier-Stokes simulations (RANS); Lagrangian Flamelet Model (LFM); LFM is reformulated to account for local inhomogeneities of the scalar dissipation rate and to demonstrate their influence; Eulerian formulation of the unsteady flamelet model for LES of non-premixed combustion is presented; consideration of the locally resolved fluctuations of the modeled scalar dissipation rate and the unsteady response of the interaction of molecular mixing and chemistry
