STUDI PENGARUH JUMLAH SUDU TERHADAP UNJUK KERJA SAVONIUS WATER TURBINE PADA ALIRAN AIR DALAM PIPA
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.
