Performance of air turbine using self- pitch-controlled blades for wave energy conversion

摘要

This work investigated an air turbine with self- pitch-controlled blades operating in the airflow generated by an oscillating water column taking real air flows to the turbine into account in order to determine turbine performance and identify the optimum blade pitch angle setting. Experimental investigations were performed by model testing of a rotor with fixed blades under steady flow conditions. Then, the running and starting characteristics under sinusoidally oscillating flow conditions were obtained by a computer simulation using a quasi-steady analysis.
