摘要：
The objective of this study is to propose a new radial flow turbine for wave energy conversion and to clarify its performance by model testing. The proposed radial turbine has a rotor blade row for uni-directional airflow and two guide vane rows. The guide vane rows are named 'floating nozzle' in the study. The guide vane rows slide in an axial direction and work as nozzle in the turbine alternately for bi-directional airflow, so as to rectify bi-directional airflow and to make uni-directional airflow. The rotor with a diameter of 500mm has been manufactured and investigated experimentally under steady flow condition which is generated by a wind tunnel using a piston/cylinder system with a diameter of 1.4m. As a result, it has been found that the peak efficiency of the proposed turbine is approximately 57% and the rotational speed of this turbine is considerably lower than that of Wells turbine.
