Abstract
A multiscale closure model for compressible turbulent mixing flows is developed in order to take into account their spectral nature and unst eadiness. A new method is introduced to calibrate the phenomenological coefficients, using the spectral properties of the multiscale closure model. It is based on the Canuto-Goldman analytical model. The Meshko v shock tube experiment is simulated.
