PENGARUH TWIST ANGLE BLADE TURBIN SAVONIUS BERPENGARAH ALIRAN APLIKASI PADA TURBIN AIR

Abstract

Water turbine is one of the mechanical equipment that functions to generate
energy into mechanical energy. There are types of water turbines one of which is
the Savonius water turbine. Savonius water turbines have the advantage of other
turbines, namely installation in rivers that do not damage the environment, are
able to work and do not require special maintenance as well as providing
weaknesses that can affect the positive force and the negative force on the rotor is
still small. This turbine has never been widespread. To make this turbine it is
possible to conduct research to improve its performance, especially in the turbine
rotor. In these words we will try the rattan turbine by varying the blade's turning
angle from 00, 30o, 60o, 90o and 120o and adding ½ and ¼ opening flow guides.
Based on the results of the research that we have done, we can say the difference
in blade angle and flow guide to turbine performance. The variation of twist angle
and flow controller that provides the most appropriate turbine performance is a
90o swivel with turbine flow guide openings ¼. At the swivel angle 120o the wave
guide is not as wide.
