New Turbine Design Model NEST-LIE

Abstract

Water is the most renewable energy resource environmentally friendly. Water energy sources are dependent on the environment and the season. The potential of location hydropower cannot be adjusted according to desire. We must follow the parameters of the existing location to get the energy. In this study, focus on small-scale power sources, according to the potential in Bali. It is Irrigation channels and streams of small rivers that do not need dams. The new turbine Nest-Lie model is designed to have high efficiency with a small water source. The parameters used as the diameter of the turbine, wide, radius and number of blades. The special parameters of Nest-Lie are pivot angle, nozzle angle and pressure. Those parameters were tested on the prototype model in the laboratory. The results obtained that the RPM on the Nest-Lie turbine produces a very significant difference, with the pressure at 28 psi produced by RPM ranges from 157.2 -231.1 where the angle of position is 0° and at the nozzle angle of 22.5°. The nozzle angle which produces the highest RPM is at an angle of 22.5° -25.5° with an angle of 0° -5° position, where RPM increases by 20% compared to without NEST-LIE.
