A Numerical Investigation of Mixing Models in LES-FMDF for

The filtered mass density function (FMDF) model has been employed for large-eddy simulations (LES) of compressible high-speed turbulent mixing and reacting flows. However, the mixing model remains a pressing challenge for FMDF methods, especially for compressible reactive flows. In this work, a temporal development mixing layer with two different convective Mach numbers, Mc=0.4 and Mc=0.8,

Numerical simulations of compressible mixing layers - NASA/ADS

Direct numerical simulations of two-dimensional temporally growing compressible mixing layers are presented. The Kelvin-Helmholtz instability is initially excited by a white-noise perturbation superimposed onto a hyperbolic tangent meanflow profile. The linear regime is studied at low resolution in the case of two flows of equal temperatures, for convective Mach numbers from 0.1 to 1 and for

Comparison of Subgrid-Models in Les of the Compressible

Large Eddy Simulation (LES) of turbulent flow forms a field of intensive research. Whereas a Direct Numerical Simulation (DNS) solves all scales present in the flow, LES solves only the large scales directly and models the effect of the small scales, represented by the turbulent stress, with a subgrid-model.
