Computational domain contains a passage of three blade profiles which were cut near the tip of long curved turbine blade. The movement of each blade was based on the results of a modal analysis which was accomplished by a software ANSYS Mechanical. The mode shape of the blade was described by User – defined function (UDF) which defines the displacement of a two-dimensional rigid body and the rotation of this body around an axis placed in the center of gravity. Numerical simulations of the steam flow through the passage were carried out for a range of nodal diameters defining a phase lag between each pair of blades on a turbine disk and the results of CFD analysis were used for the computation of aerodynamic work of the steam on the blade surface to assess the blade stability.
