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.

Keywords
