To the question of the rational design of turbine stages with tangential inclination of guide blades

In this article, we have explored the influence of methods for rational design of turbine stages with
tangential inclination of guide blades on the characteristics and flow structure. We have constructed
calculation models for three turbine stages with tangential inclination of guide blades. 3D-testing gasdynamic
calculations were performed in the ANSYS CFX software package. We have constructed graphs for
the efficiency, the degrees of reactivity at the root and at the periphery depending on the parameter. The
distributions of flow parameters (flow angles, the coefficient of kinetic energy losses for the guide vanes and
the impeller, outlet velocity ) have been given by blade height. The calculation results between three turbine
stages have been compared. The conclusion about the influence of methods of rational design of turbine
stages with tangential inclination of guide blades on the characteristics and flow structure has been given.
