Abstract
A method for flow optimization in multi-stage turbine-type machines in which the inflow of a third of three consecutive blade rings is optimized, the first and the third blade ring having the same number of blades being situated on the same unit, rotor or stator, the second blade ring being situated on the other of the two units, rotor or stator, and an operating state, occurring during a high proportion of the operating time, being selected by ascertaining or predefining the appropriate operating parameters. In this operating state, the maxima of the obstruction, periodically occurring in the area of the outlet edges of the blade profiles of the second blade ring, are deflected onto the inlet edges of the blade profiles of the third blade ring within a predefined tolerance angle; the positions or the geometries of blade profiles of at least one of the three blade rings are modified as needed.
