Abstract. By using concentrators and flow-forming elements, the efficiency of power plants can be significantly improved.
The purpose of the study was to analyze the design solutions of hydropower plants, to determine the use of new technical solutions for flow-forming elements that significantly improve the energy performance of such plants.
The classification of flow concentrators and flow-forming elements is developed. In the analysis of which it was shown that when developing a classification of flow concentrators, next to the main structural types, it is necessary to distinguish subtypes that use additional devices that allow you to take into account the specific working conditions of concentrators, increase their efficiency, provide protective measures in relation to the environment, etc. .P. Thus, the refined classification makes it possible to more fully represent the whole variety of flow concentrators and flow-forming elements, to facilitate their selection for specific conditions, to contribute to the selection of effective ways of developing and improving such devices. Improvements have been made to the design solutions of power plants with flow concentrators and refinements on the classification of flow concentrators allow us to formulate the following conclusion: as a result of the analysis of new design proposals, a classification of flow concentrators has been developed, which allows more fully representing the whole variety of flow-direct devices, facilitating their selection for specific conditions and facilitating the selection of efficient ways to develop and improve such devices.
Key words: flow concentrator, power plants, hydropower plants, wind turbine, wind flow
