Abstract:
Zonal approach for URANS problem solution is described. Original feature of this approach is to
use CFL∼1 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, viscous turbulent gas, zonal approach, wind tunnel, scale effect, high lift configuration.
