The equations,of motion on S2 stream-surface are presented with the flow angle β as a characteristic parameter. The solution of these equations within the blade channels is simplified by expressing the blade force F in terms of the geometric parameters of the stream-surface.Emphasis is laid upon the discussion of the loss-distribution along the blade length and the calculation of the average flow conditions and entrppy gradient behind the stage.Two calculated examples are given.

The equations,of motion on S2 stream-surface are presented with the flow angle β as a characteristic parameter. The solution of these equations within the blade channels is simplified by expressing the blade force F in terms of the geometric parameters of the stream-surface.Emphasis is laid upon the discussion of the loss-distribution along the blade length and the calculation of the average flow conditions and entrppy gradient behind the stage.Two calculated examples are given. One of them shows the effects of the entropy and enthalpy accumulation in multistage turbines. The other compares the solutions of the equations within the blade channels and in the axial gap between two blade rows.
