The purpose of the work is to obtain technical and economic effect in hydropower in the development of flow parts of pump-turbines, horizontal high-head radial-diagonal, diagonal-axial with dual runner systems in relation to typical hydraulic units of horizontal and vertical types by creating mathematical models that will significantly increase the average operational efficiency, increase reliability and durability during their operation. Research method - the method of block-hierarchical mathematical modeling of the working process of high-head hydraulic turbines and pump-turbines, methods of solving direct and inverse problems of the theory of blade hydraulic machines, methods of numerical modeling of hydrodynamic characteristics based on the proposed mathematical models and their comparison with modern packages, study of spatial flows in flowing parts. Based on the results of research, new types of hydraulic turbines have been developed, mathematical models of the working process have been improved, which has allowed to expand the possibility of their operation in a wider range. The field of use of the results of work - energy engineering. The economic effect of implementing the results of research work at Ukrainian HPPs, as well as the development, improvement and reconstruction of hydro turbine equipment, can be up to 10-20 million US dollars per year.
