The article describes a method for calculating the power of a gravitational micro hydroelectric power station with an air funnel. The design model of the installation operating due to the high-speed water pressure is considered. The filling factor of the turbine chamber is introduced. The dependence of the turbine output power is obtained taking into account this coefficient.

В статье рассматривается задача разработки гравитационной водоворотной микроГЭС (ГВВмГЭС), в которой для выработки электрической энергии используют скорость течения водоворотного потока, формирующегося за счет гравитации. Такая технология является относительно новой в области гидроэлектроэнергетики. Течения потока жидкости в ГВВмГЭС с тремя различными моделями гидротурбин в цилиндрическом бассейне были смоделированы использованием программы KompasFlow. Основное уравнение движения жидкости это уравнение Навье-Стокса. Изложена подробная описание алгоритма моделирования. Представлены результаты численного эксперимента моделей.

This paper discusses the issues of assessing the prospects for the use of gravitational water vortex hydroelectric power plants. The analysis of the designs of hydraulic turbines is carried out, their advantages and disadvantages are considered, the methods of their installation in the turbine chamber, as well as the experimental determination of the efficiency. The results of threedimensional modeling of various types of hydraulic turbines are presented. The kinematics of the interaction of the turbine blades is considered, with the establishment of a connection between the kinematic parameters and the power of the hydraulic turbine.
