Pengaruh Sudut Sudu Terhadap Pengarah Turbin Helikal Pada Pembangkit Tenaga Listrik Di Irigasi Bendungan Seluma Bengkulu

Abstract

The Gorlov certical axid water turbine is suitable ti hardness the water flow in the creation of kinetic energy for the irigation dam, the turbine tasted in this study was ther Gorlov helical turbine blade with steering angles of 0^o, 30^o, 45^o, and 60^o turbine diameter (d) 0f 0,30 m. height (h) 0f 0,50 m and the NACA 0020 profile. the testing was conducted on the irigation dam of seluma Bengkulu. The water flow showed in the velocity (Uair) of 0,85 m/s and a round (n) of 110 rpm. The results were archieved by setting the blades in the steering torque coefficient (CT) of 0.309 are turbine efficiency (nt) of 28.5% and a power turbine (PT) of 13.699 watts.
