The simulation of the buoy for oscillating wave energy converter with Flow 3D

In order to ensure energy collecting efficiency of oscillating wave energy converter in the actual application of Donggang's sea area in China, Flow 3D software is used to simulate hydrodynamic performance of different shape of the buoy. The result is : The average mass center z coordinates of the butterfly cylinder is higher than the hollow cylinder and vertical cylinder. So is the vibration velocity. The result shows that: The motion response of the butterfly cylinder is better than the hollow cylinder and the vertical cylinder. So the butterfly cylinder is more appropriate to be used in Donggang sea area. This can be an important reference for the application of the buoy in Donggang sea area.
