description: The report examined new scientific approaches to the creation of a combined cogeneration energy complex based on small or micro-hydropower. In particular, the most effective approaches to micro-hydropower facilities were considered to create a workable structural layout and design small and micro-class hydroturbines with high energy efficiency for them. A criterion has been developed that makes it possible to evaluate the energy efficiency of hydro-turbines at an early stage of design using the calculation method, including a predictive estimate of the hydraulic resistance function Î¾ht = f(Re) of a particular penstock geometry. The results of the theoretical task of creating a technologically advanced configuration of a blade system using Nicholas E. Zhukovsky theory. By calculating and numerically (CFD) simulating the hydrodynamic lattices of flat profiles, the theoretical nomograms for determining the coefficients Cx and Cy are confirmed and supplemented. A series of comparative results of computational and experimental studies of the combined energy complex hydraulic part â microhydroturbines with exper-imental blade systems, including those modified by the principle of biomimetics (nature imitation technologies) is presented. Based on the calculated and experimental studies, the prospects of the chosen direction of development of small and microhydroenergy are shown, as well as the effectiveness of the approaches that were used in the design of the working bodies of microhydro-turbines.
