Description
Using the data of the direct numerical simulation (DNS) for the turbulent compressible channel flow with the isothermal walls, a priori test for the one-equation subgrid-scale (SGS) model for turbulent compressible flows is performed. It is comfirmed that the model expressions for the grid-scale (GS) viscous and diffusive terms, SGS temperature-dilatation term with the filtering DNS's heat flux, SGS stress-strain term are effective. The SGS stress and flux are modeled by using the GS strain and coherent structure model function. From a posteriori result of the large-eddy-simulation (LES) using the proposed SGS model, the present model can reproduce the DNS one qualitatively.
