Abstract
The results of theoretical computation work and experimental studies of the geometry of the confuser-diffuser direct-flow duct of a hydraulic generator are presented. The purpose of the paper is to establish the optimal, in terms of the capacity of the hydraulic generator, angles of the flow contraction in the inlet confuser and the angles of the flow expansion in the outlet diffuser, to determine the appropriate ratio of the length of these components with the diameter of the duct neck and to increase the efficiency of the hydraulic generator. In the study of the direct-flow duct geometry of the hydraulic generator, we used micromanometric construction of velocity and flow pressure diagrams, while the Pitot-Prandtl high-speed tube was used as a receiving element and the MMH type micromanometer was used as a recording element. The research results have shown that the optimal angles of the flow contraction in the confuser are 30–35° with its length of not more than 1–2 diameters of the duct neck, and the optimal angles of the flow expansion in the diffuser are 7–8° with its length of at least 4–5 diameters of the duct neck. In the course of the study, the optimal geometry of the confuser-diffuser direct-flow duct of the hydraulic generator was established, which provides the highest capacity and, consequently, the highest efficiency. The latter indicates the feasibility of practical application of the research results in the development of new hydraulic generators that convert water flows into electrical energy.
