The paper deals with application of hybrid RANS/LES turbulence model for computation of flow in axial turbine stage at off-design operation regime. This operating regime is characterized by massive separation of the boundary layer on the suction side of the rotor blades which leads to high-swirl flow field behind the axial stage. Used hybrid RANS/LES model is based on transport equation for the kinetic energy which is shared in both RANS and LES modes. The model is implemented into the in-house numerical code which was originally designed for solution of RANS equation. Therefore the numerical inviscid fluxes are modified here in order to reduce a native numerical dissipation for use in LES approach
