The purpose of the work is to obtain a technical and economic effect in industry in the development of flowing parts of direct-flow horizontal high-head radial-diagonal, diagonal-axial and with blade systems of runner in relation to hydraulic units of horizontal and vertical types by creating mathematical models of optimized workflows. increase efficiency, increase reliability and durability during their operation. Research method - methods of mathematical modeling of the working process of the hydroturbine, methods of solving the direct and inverse problem of flow around the lattice of profiles, methods of numerical simulation on a computer are used in the work. Based on the results of the research, new types of hydraulic turbines were developed, including the improvement of the mathematical flow model, which allowed to expand the possibility of their operation in a wider range of heads and costs at high efficiency, as well as increased reliability and durability of equipment. The field of use of the results of work - energy engineering. The economic effect of implementing the results of R&D at Ukrainian hydropower plants, as well as the development, improvement and reconstruction of hydro turbine equipment, can be up to 10-20 million US dollars per year.
