As a sea wave comes to the shore then recedes from it, there is significant energy associated with the movement of the wave's water. One way to extract this energy is to have the moving water push and pull on an oscillating vane. This work examines numerically the flow and forces associated with such a vane in a typical wave condition, using a commercial Computational Fluid Dynamics (CFD) software package. The vane is a rectangular plate hinged at one edge and oscillating about it. Effects of plates shape on the flow pattern and developed forces are investigated. Changing the plate shapes can results in more energy extraction from the device.
