摘要：The turbine based on the oscillating foil has an obvious advantage in the application of shallow water. Following the existing studies which a hydraulic system is used to couple two foils and realize the self-sustained oscillation motion. In this study, the effects of foil thickness on the system response are examined by using a 2D numerical approach. Two foils have almost the same heaving response for the symmetric foil. A thinner foil has a poor hydrodynamic performance because it occurs dynamic stall more easily. A thicker foil can’t get a large lift force because no leading edge vortex which plays an important role in the hydrodynamic forms on the foil surface. The NACA0015 foil is more suitable for the application of oscillating foil generators owing to the favorable hydrodynamic behavior and energy harvesting performance. © 2019 Association for Computing Machinery.
