RESEARCH ON PURPOSE OF DETERMINING THE OPTIMAL CONFIGURATION OF BLADES FOR IMPROVING THE ENERGY EFFICIENCY OF DIRECT FLOW HYDRO TURBINE

Abstract

In this paper we present the results of the research conducted to determine theeffective variant of guide vane and hydro wheel blades of direct flow hydroturbine. The aim of the theoretical study is to determine the optimalconfiguration of hydro turbine blades to improve the energy efficiency of thehydro turbine. As a result of the theoretical study, a mathematical model of ahydro turbine was developed in the interactive COMSOL Multiphysics. Withthe help of the COMSOL Multiphysics application program, the change invelocity and pressure distribution of water through the guide vanes and hydroturbine blades the optimal shape and angle of the guide device and the hydrowheel blades of the hydro turbine were determined. Based on the results of theresearch, it was determined the optimal configurations of the hydro wheelblades with high energy efficiency.
