Zonal approach for URANS problem solution is described. Original feature of this approach is to use $\mathrm{CFL}\sim1$ in the main part of calculation domain excluding thin part of boundary layer. It is achieved by using explicit numerical scheme with fractional time stepping in the main part of calculation domain. In the near-wall zone of boundary layer, implicit dual stepping method is used. In addition to zonal approach, fully implicit method with dual stepping technology is also implemented. The methods are verified in comparison with the results of test case data obtained by consortium participants within DeSiReH FP-7. Special attention is paid to examples of authors' experimental studies, which used preliminary CFD prediction to gain new quality of experimental data. The problem of cryogenic tests is studied separately. Some results confirm that relative difference of integral drag and lift coefficients in ideal and cryogenic cases is not essential.
Keywords: explicit-implicit numerical method, zonal approach, wind tunnel, high lift configuration.
Mots-clés : viscous turbulent gas, scale effect
