Wave energy converter using oscillating water column (OWC) is one of the widely used wave energy conversion technologies in the world. In this method, an air turbine is driven by a bi-directional airflow generated in an air chamber by the OWC motion of ocean waves. A sail wing turbine has attracted attention as a new candidate for the air turbine for bi-directional flow. In this turbine, a rotating sail rotor made of a thin and flexible material such as cloth changes its shape in response to the wind direction and operates in a bi-directional airflow. In this study, a wind tunnel experiment under steady flow conditions were conducted to investigate the effect of rotor frame thickness on turbine performance in order to clarify the performance of sail wing turbine for wave energy conversion.
