Abstract

Large scale hydropower energy recovery is now an established technology. However the recovery of hydropower energy from small scale resources has yet to be exploited. The potential of this small scale energy resource in Indonesia is 450 MW. This source of energy is currently unexploited due to non-existence of an economically viable technology to extract the energy from these low power sites.

The turbine wheel is one type of water wheel which was proposed in 1848 as an alternative machine for small scale hydropower. The application for this machine was for use in water courses where the head differences ranges of 2.5-5m. This research is conducted in order to observe the performance and the characteristics the turbine wheel. The research was undertaken by testing a turbine wheel in a recirculating flume.

The experiments undertaken shows that the efficiency of this machine approaches 70%. The water flow volume of this machine is in the range of 1.85 m3/s to 5.23m3/s per m width. In addition, the maximum power output is between 28.74 kW and 162.56kW per m width. A theory is proposed which calculates theoretical power output for the machine correlates well with the experimental results. Furthermore, the power losses can be identified as turbulent losses only, with the turbulence coefficient Cd of 3.8.
