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.

Summary
The whole world pays great attention to water flow energy as the effective source of energy. Build the dam is a very complex construction, and it occupies a very large area, has a negative effect on the life of aquifers, when water accumulates in the dam, if there is a problem with the dam, can cause a serious catastrophe, may be dangerous to the environment. Instead, it works in scheme as a part of the water given to head tube, after flowing through hydro turbine again dumped into the river. It works in scheme as a part of the water given to head tube, after flowing through hydro turbine again dumped into the river This direct flow hydro turbine’s size is small, so to construct it needs less material it costs cheaper
