The turbine used for a wave-power-generating system is driven by the oscillating airflow produced by the water wave motion. The Wells turbine has the simple vane-less structure using no-twist and symmetrical blades, which drives its unidirectional rotational motion even though the turbine is driven in the oscillating airflow. In this paper, the important characteristics of the turbine are theoretically derived by the potential theory of cascade. The deflection angle in the absolute field does not depend on any angle of attack, but is always constant. The deflection angle depends only on the arrangement of the cascade. Moreover, the pressure drop coefficient is proportional to the rotational speed at the same axial velocity and proportional to the axial velocity at the same rotational speed.
