Modeling of design parameters of a screw turbine for a microhydro power plant

Abstract

Microhydroelectric power plants with screw turbines operating on low-pressure watercourses represent a new form of small-scale hydropower. Modeling of the design parameters of a micro-hydroelectric power station with two parallel screw turbines operating in low-pressure water flows, and the optimal values were determined. The purpose of the conducted scientific research is the screw turbine outer diameter (Do), inner diameter (Di), total length of the screw (L), the number of blades (N), the angle of inclination of the screw (𝛽), the length of one revolution of the blade (S), the height (H) of the pressure generator is to increase the efficiency of the impact on the number of revolutions, torque and mechanical power based on the correct selection of optimal options.
