Abstract

The problem of homogenous isotropic turbulence interaction with steady normal shock is considered. Comparison of some variants of k- 8 - and к- CO -models is presented. Special attention was paid to influence different non-equilibrium modifications of the models on turbulence level increasing behind the shock.

Keywords:
