The method consists in a superposition of two algorithms: a quasi-three-dimensional method of the main flow calculations and a method for the flow prediction in the cavities between the stator and rotor discs (side-flows). The interactions between these two flow regions have a significant meaning for the turbine efficiency calculations. as well as for the axial force prediction. The three-dimensional maps visualising the behaviour of parameters of a group of stages are presented . Differences in the calculation series are connected with changes occurring in the geometry of the parts influencing the directions of side-flows (e.g. stator disc holes).
