Abstract

The article presents the principle of operation of a jet turbine with a nozzle based on the "Segner" wheel and studies its shortcomings. In order to eliminate the identified shortcomings, a guide device was developed, which is installed inside the hydraulic turbine impeller. Using the Bernoulli equations and the Zhukovsky theory, the energy parameters of a microhydroelectric power station with a developed divertor device and the water flow rate in a hydroturbine are determined. The energy parameters calculated on the basis of theoretical results are analyzed, and it is found that the efficiency of a hydroturbine increases by 10-20% depending on the water pressure. This describes the guide device and the technical solution for its placement.
