Abstract  Various approaches to the numerical simulation of wallbounded turbulent flows have been considered. Turbulence models have been assembled to allow equal proper description of the coreflow vortex parameters as well as local friction coefficient in nearwall domain. Different modifications and combinations of turbulence models have been applied, namely, RANSbased lowReynolds models, standard LES approach and modified DES models. Testing calculations have been carried out for the flat plate flow and duct flow. The comparison of achieved results with known experimental and numerical data has been shown through the local friction coefficient, vorticity magnitude and distribution of velocity versus distance to the wall.
