DEVELOPMENT OF A MODEL AND ALGORITHM FOR DETERMINING THE OPTIMAL ANGLE OF THE UNDERSHOT WATER WHEEL BLADES

This article presents the results of theoretical studies of the undershot water wheel that works effectively in low-pressure watercourses with a water flow speed of 1-4 m/s. When developing a mathematical model of the undershot water wheel, the Matlab/Simulink program was used. According to the results of the study, it was found that for the efficient operation of the undershot water wheel in low-pressure watercourses, the angle of inclination of the blade at the exit from the water is β=30°. Also, during the study, the water flow rate and the efficiency of the undershot water wheel were determined
