Abstract
An oscillating water column (OWC) type wave energy converter is composed of a partly submerged wall, an air chamber, an air turbine and a generator and is considered to be safe even under the storm condition. Besides, an impulse turbine as the secondary conversion device in the OWC unit is expected to achieve the high efficiency. In the previous research, the authors investigated the effects of the air chamber length on the primary and secondary conversion efficiencies experimentally. Continuously, in this paper, the 2-D wave tank tests in regular waves for the performance evaluation of the fixed OWC type wave energy converter with the impulse turbine were conducted, and the effects of the impulse rotor inlet/outlet angle, the guide vane's number and the guide vane's setting angle are shown experimentally.
