Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract. In this paper the results of the research conducted to determine the effective version of hydro wheel blades of direct flow hydro turbine are presented. The aim of the research is to determine the optimal configurations of hydro turbine blades to improve the energy efficiency of the turbine. As a result of the study, a mathematical model of a hydro turbine was developed in the interactive COMSOL Multiphysics. Research was performed in the COMSOL Multiphysics application program with using Reynolds Averaged Navier Stokes method to Navier-Stokes equation for incompressible fluid. Direction of flow to blades with changing attack angle along blades was investigated. The change in velocity and pressure distribution of water through hydro turbine blades was considered. The optimal location of the blades was determined. Defined lift and drag forces acting along the blade. Based on the results of the research, it was determined the optimal configurations of the hydro wheel blades with high energy efficiency.
