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 the effective variant of guide vane and hydro wheel blades of direct flow hydro turbine.  The aim of the theoretical study is to determine the optimal configuration of hydro turbine blades to improve the energy efficiency of the hydro turbine. As a result of the theoretical study, a mathematical model of a hydro turbine was developed in the interactive COMSOL Multiphysics. With the help of the COMSOL Multiphysics application program, the change in velocity and pressure distribution of water through the guide vanes and hydro turbine blades the optimal shape and angle of the guide device and the hydro wheel blades of the hydro turbine were determined. Based on the results of the research, it was determined the optimal configurations of the hydro wheel blades with high energy efficiency.
