Issues related to numerical analyses of turbine stage stator/rotor interactions are disceussed, with special focus on the selection of grid parameters to secure proper modelling of the stator wake's dissipation. Unsteady calculations of the flow through a high-pressure turbine stage, based on 3D ORANS equations, are employed in the grid resolution analysis. Their results are compared with those obtained with other methods, both developed by the author or available in the literature. As a result, the 3D grid resolution of the order of 2000000 cells per one stator and/or one rotor passage has been determined as the necessary minimum for properly modelling the dissipation of the stator's wake on its war through the rotor's cascade, under the circumstances determined by the used CFD code. A generalization of this result is proposed.
