Abstract

Water in vertical wastewater pipes has the potential to produce electrical energy due to its big momentum force. This paper proposed a Savonius turbine as an electric generator which works efficiently at low speed and limited head. This study specifically aims to investigate the effect of the overlap ratio of the blade mounted on a 3-inch diameter pipe at a maximum head of 2m at Savonius Horizontal Axis Water Turbine (HAWT) to the coefficient of power and tip speed ratio. The optimal result of this study was obtained in the blade overlap ratio of 0.3 at every discharge. The most optimal performance occurred at the discharge of 11.9 l/s with variation of overlap, while 0.3 had the most optimal performance of 30.58 Watt power output, TSR of 0.79 and power coefficient 0.19.
