Abstract	The work is devoted to the peculiarities of the implementation of hybrid Reynolds’ Averaged Navier-Stokes equations-Large Eddy Simulation (RANS-LES) approaches of the Detached Eddy Simulation (DES) family for simulation of complex near-wall turbulent flows using unstructured meshes. The problems of determining required geometric characteristics in the mesh nodes and adaptation of hybrid approaches to the used accurate numerical approximation scheme in space are considered. The classic benchmark problem of the decay of homogeneous isotropic turbulence and the results of the computation of a complex turbulent flow near the wall with the presence of flow separation and reattachment are considered to verify the implemented technique and to demonstrate its efficiency.
