One of the modification of Large Eddy Simulation method is developed. It is applied to the problem of mixing of two supersonic flows. Kelvin-Helmholtz instability is obtained. Instantaneous data are averaged and the shear layer thickness is calculated. It is compared with the experimental one. The conclusion about the sensitivity of the method to the change in model constants is made.
