Abstract

The propeller turbine is a water turbine that is suitable for use at low heads such as irrigation canals and rivers. Hydrokinetic energy development is the most feasible option in Indonesia. However, currently the development of hydrokinetic energy in Indonesia is still very low. The propeller turbine is a water turbine which is suitable for use at low heads. This turbine is classified as a microhyro and has a head between 1-5 m. This study was conducted to compare the effect of using a double rotor on a propeller turbine. Changes in turbine performance were reviewed through the rotational speed of the rotor, torque, mechanical power and turbine electrical voltage. This research was conducted experimentally in a closed-loop test section. A pump drives fluid flowing in the closed-loop test section at flow rates of 0.05, 0.1 and 0.15 liter/s. the use of a double propeller turbine results in an increase in turbine performance above 5%. This is because turbines with double rotors have a large cross-sectional area compared to single-rotor turbines. Thus the energy contained in the fluid can be transmitted optimally to drive the turbine surface with a double rotor.Keyword: Turbin Propeller, Double rotor, microhydro

Abstract

The availability of non-renewable energy has recently been running low and so impacts electrical energy. Renewable energy is converted from natural sources to kinetic energy. The Double Propeller Water Turbine is a water turbine that is suitable to be applied using a small flow head. This research is a development of previous research by changing the degree of inclination of the blade angle on the turbine, which is used to determine changes in the power and efficiency of the Double Propeller turbine at various speeds. The results showed that the Double Propeller turbine rotation’s performance was directly proportional to the slope of the turbine blade angle. The optimum angle of attack on the hydro turbine affected the lift force and the ability of the water flow to capture water power. At the lowest blade angle, which is 20 degrees, the highest rotational speed is obtained with a value of 335 rpm. The turbine generates the most significant power with a blade angle of 20o, with a value of 4.81 watts, and the highest efficiency is 24%. The degree of blade angle affects the performance of the Double Propeller turbine.
