Abstract

Rainwater, flowed through a pipe, has potential energy that can be used to drive a turbine coupled with generator. Savonius water turbine with horizontal axis is used here as the turbine. The research compares the Savonius water turbine with different blade number of 2, 4, 6, 8, 10 and 12 using Computational Fluid Design (CFD) of SolidWork 2013. The turbine specifications have the angle of curvature about 70°, the aspect ratio of 1, the end plate ratio of 1,1 and deflector angle of 45°. The data obtained in this paper are the pressure contour of Savonius turbine blade, the velocity of fluid flow and the torque generated. The aims of the research are to obtain the influence of the blade number in the Savonius turbine to the turbine performances and to obtain the best of blade number. The results show that two blades has the best performances compared with the others. It has the highest torque about 5,75 Nm for the same conditions as well. Keywords: power, Savonius turbine, torque, blade, flow

Abstract

Savonius water turbine is one of the simplest design and low cost production that attracts wide attention. A single stage Savonius water turbine with horizontal axis is applied in a pipe with diameter of 3 inch to give variation in the deflector angle. Deflector is used to focusing the flow so the torque is increased by the blade curvature in the turbine. This simulation uses the SolidWork 2013 software. The aim of this simulation is to obtain the best performance in each deflector angle, then the result is compared with a turbine without deflector. The deflector performance is analyzed by the pressure contour, the torque and the angle of attack. The deflector angle is vary in different angle of 20°, 30°, 40° and 50° with the deflector ratio of 50%. By using debit input of 12,2x10-3 m3/s, the results show that angle deflector of 30° is obtained as the best performance where it produce the pressure contour about 279820,99 Pa, torque of 0,6070 Nm and more stable in angle of attack. Keywords: picohydro, SolidWork, Savonius, deflector, torque
