Even with such a requirement, LES reduces dramatically the computational effort necessary to simulate the shock/homogeneous turbulence interaction with respect to DNS. Dynamic SGS models are found to improve markedly the quality of the results when compared to simple models like Smagorinsky’s.

Deconvolution of Subgrid-Scales for the Simulation of Shock-Turbulence Interaction,proach is based on an expansion of the filtered field in terms of filter width, which is modified in the vicinity of discontinuities in order to exactly recover the filtered profile. We detail both approaches and investigate their feasibility for the inviscid Burgers equation, isothermal and full Euler equations.

Exact Expansions for Filtered-Scales Modelling with a Wide Class of LES Filters,namics. An approximation of this expansion is also derived for filters with a compact support in Fourier space. In this case, the filtered-scale can be decomposed into two parts corresponding respectively to reversible and irreversible effects.
