Abstract

The large eddy simulation LES of compressible turbulent channel flows at three different Mach numbers is performed in the present work by extending the dynamic mixed subgridscale SGS model to compressible flows The turbulent statistics agree well with those from the existing direct numerical simulation DNS results indicating that the LES method established in the present work is reliable The analysis of the turbulent fluctuations computed by the present LES reveals that the flows considered in this work follow the Morkovin’s hypothesis Thus the compressibility effects are dominated by the mean field properties and the relevant statistical ratios are invariant to the variation of Mach number The nearwall streamwise streaks are more coherent and the spacing between streaks is wider as the Mach number increases This can be regarded as a direct feature characterized by the compressibility effects The restrained influences of compressibility effects on the production and dissipation of the turbulence kinetic energy are also identified based on the present LES results
