Abstract
A new subgrid-scale (SGS) one-equation model of the large eddy simulation (LES) for compressible turbulent flows, which includes the coherent structure model function suggested by Kobayashi, is proposed by the theoretical analysis of the two-scale direct-interaction approximation. Using the direct numerical simulation (DNS) data of the compressible turbulent mixing layer, a priori test for the model expression is performed. In the LES, we show that the predictions of the present SGS model reproduce the DNS results.
