STUDI SIMULASI PENGARUH SUDUT DEFLEKTOR PADA SAVONIUS WATER TURBIN DENGAN SUMBU HORIZONTAL TERHADAP POWER GENERATION ALIRAN AIR DALAM PIPA
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 m 3 /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.
