Harnessing natural energy has been a topic of interest and development in recent years. Waves are an important renewable energy source and can make a significant contribution if harnessed properly. The basic characteristic of a wells turbine is that for bidirectional flow, the turbine rotor rotates in the same direction. In this paper, the NACA0015 Wells turbine was used to study the effect of tip clearance and airfoil on the performance characteristics of the fillet. Wells turbines are most commonly used for wave power generation and have been the subject of many studies. We used the Navier-Stokes code Fluent to calculate the flow field of the Wells turbine. The CFD results were compared with experimental data for validation, and the CFD results show good agreement with the experimental results. The tip clearance was varied from 0 to 10% and the fillet was varied from 0,1,3,5%.
