Wells turbine has long been used as an energy converter for wave energy conversion because of its simple structure. In order to alleviate the stall problem of this turbine, the authors have proposed a Wells turbine with booster for wave energy conversion. This unique power take-off consists of the Wells turbine for main turbine and an impulse turbine for booster. In the present, the turbine performance is estimated by the numerical analysis (CFD). As a result, the performance of Wells turbine for wave energy conversion can be improved by use of booster turbine at high flow coefficient.
