      kε-model of turbulent mixing in 2-D compressible flows is described. The model is implemented in Lagrangian-Eulerian gasdynamic method used to calculate flows with large strains. The above method can be used also to simulate turbulent mixing due to combined effect of gravitational and tangential instabilities. Computational results are compared with experimental and other methodical data.
