The paper deals with application of hybrid RANS/LES model based on two-equation k– ω model in RANS mode and transport equation for the sub-grid scale turbulent energy in LES mode. Hybrid RANS/LES model is applied for computation of flow in an axial turbine stage with radial gaps under the stator and above the rotor blade. 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.
