A numerical method for a direct simulation of the large-scale turbulence is proposed based on the Smagorinsky model of subgrid-scale turbulence. 2D and 3D numerical modeling of supersonic shear layer using the given method at the Alpha XL 266 workstation is presented. Numerical and experimental results are compared and an analysis of this comparison is given as well. A special attention is paid to a significant difference between 2D and 3D calculations and the reason for this difference is discussed. The possibility of using a personal computer in such calculations is investigated. In particular, the processing time and virtual memory used are estimated for each calculation.
