This study experimentally investigates the performance of a newly proposed rotary-type wave energy converter employing passively pitching symmetric hydrofoils to extract wave-induced drag forces and produce continuous, unidirectional rotation and torque. A systematic laboratory-scale experimental campaign is conducted in a controlled wave flume under regular wave conditions representative of intermediate- and shallow-water waves. The effects of wave height, wave period, rotor submergence level, and imposed rotational speed on conversion efficiency are examined through direct torque and rotational speed measurements. Stable mechanical power extraction is demonstrated across the investigated parameter space, with a maximum conversion efficiency of 8.17% achieved for a wave height of 10 cm, a wave period of 2 s, a frequency ratio of 0.5, and a rotor submergence level of −10 cm. The results establish experimental proof-of-concept in terms of stable operation, sustained torque generation, and continuous rotation, addressing limitations of earlier drag-based rotary systems associated with oscillatory behavior and incomplete rotation, and provide a basis for subsequent investigations addressing scaling effects and performance under more representative wave conditions.
