The purpose of the study is to significantly improve the efficiency, increase the reliability and durability of radial-axial hydroturbines to 200-1000 m pressure heads and single-stage hydroelectric generators for heads of 40-250 m. Research methods - experimental and calculated analysis of the features of the working process and flow structure on the basis of the fundamental laws of hydrodynamics. Results - hydroturbines with a wide range of operation for heads and costs (capacities) with a 5-10% higher average operating efficiency Novelty - A more sophisticated mathematical model of turbulent fluid motion has been developed in the channels of radial-diagonal hydroturbines, which will make it possible for the first time in the world practice to use 800- 1000 m bladed hydroturbines for heads and 50-250 m for direct hydroelectric generators. Scope of application-hydroelectric equipment for hydraulic and pumped storage power plants of HPPs and PSPs. Product Description popup.authors Бондаренко О.Ю. Гасюк О.І. Дранковський В.Е. Коваль О.С.
