Inclined wavemaker inlinear water wave theory Original Research Article

A model for a paddle-type wavemaker coupled to 2D fluid flow over a plane beach isstudied. For purely outgoing wave motion, we find that the wavemaker has positive and negative added moment of inertias. When the wavemaker is used to extract energy, the efficiency is found to be at most 100% which is achieved when there is no reflected wave.
