Pengaruh Jumlah Sudu Terhadap Kinerja Turbin Savonius

Jamal Jamal

Abstract


Savonius wind turbines are wind turbines that can
operate at low wind speeds, this type of turbine is very suitable to
be used in several places in Indonesia. The research aims to
improve the performance of the Savonius wind turbine with
variations in the number of turbine blades as well as variations in
the velocity of wind speed. The research method was
experimental where wind turbine testing was carried out with
variations in the number of turbine blades with number of 2, 3
and 4 blades, other variations carried out were wind speed at 3.5;
4,5; 5.5 and 6.5 m/s. The study results show that the 2-blade
turbine produces greater rotation, but the torque moment is
lower than the 3 and 4 blade turbines, this can be seen in the low
efficiency of the 2 blade turbine at low wind speeds with high
loading. At 3.5 m / s wind turbines 2 blade turbines have
efficiency that tends to be the same as 3 and 4 blade turbines up
to 0.5 N but at loads of 0.6 - 1.2 N 2 blade turbines have lower
efficiency, while at wind speeds of 4.5 - 6.5 m / s 2 blade turbines
have greater efficiency than turbines 3 and 4 blades up to a load
of 1.2 N but if the load is added then the efficiency of 2-blade
turbines can be smaller than efficiency 3 and 4-blade.
