In this study,in order to enhance the performance of Wells turbine for wave energy conversion,the effect of 3-dimensional airfoil on the turbine characteristics has been investigated experimentally by model testing under steady flow conditions and simulated numerically by quasi-steady analysis under sinusoidal flow conditions.And then,the performances of Wells turbine with 3-dimensional airfoils have been compared with those of the original Wells turbine,i.e.,the turbine with 2-dimensional airfoils.As a result,it has been found that the performances of Wells turbine with 3-dimentional airfoils depend on the blade profile at tip.
