Abstract Various approaches to the numerical simulation of wall-bounded turbulent flows have been considered. Turbulence models have been assembled to allow equal proper description of the core-flow vortex parameters as well as local friction coefficient in near-wall domain. Different modifications and combinations of turbulence models have been applied, namely, RANS-based low-Reynolds 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.
