DESIGN AND PERFORMANCE TEST OF THE SAVONIUS TYPE VERTICAL SHAFT WATER TURBINE USING THE ADDITION OF A CONCENTRATOR

Abstract

Currently, the availability of fossil energy is decreasing, the use of fossil energy has been overused. So that we need renewable and environmentally friendly energy sources to replace the depleting fossil energy. One of the renewable energies that can be used as a substitute for fossil energy is water energy. The purpose of this study was to determine the effect of adding a water flow concentrator on the performance of the Savonius Type Vertical Shaft Water Turbine. This study used experimental design research. The results showed that the addition of a water flow concentrator affected the performance of the turbine. The Savonius Type Vertical Shaft Water Turbine with a concentrator gives a higher effect on the water flow rate of 2.17 m / s, with a turbine rotation of 94 rpm, the highest turbine power produced by the turbine is 176.6 Watt, and the turbine efficiency is obtained 85%
