The objective of the present study is to develop an efficient turbine that can be used to extract micro hydropower potential of relatively high head and critical low flow rate range. It requires vely low specific speed turbines which are lower than conventional impulse turbines' specific speed. For this purpose, we develop a new Positive Displacement Turbine (PDT). In order to reveal the performance characteristics of the new turbine, one conventional impulse turbine, which is used for automatic water faucet system, was tested for comparison. The test results show that the PDT is much more efficient than a conventional turbine. The efficiency of the PDT is much improved and sustains high efficiency under the wide range of operating conditions when reducing its side clearance. The pressure pulsations at the inlet and outlet of the PDT can be considerably minimized by using simple dampers.
