    Wave pumping : Toward a novel way to harvest energy from waves

    Résumé : Wave power represents a tremendous unexploited potential with an estimated 2TW of power available worldwide (Gunn it al. 2012). Several designs have been developed in the past decades and outlined three main challenges : capital and maintenance costs, unsteadiness in the supply and survivability to stormy weather. To answer these points, we look into ways to convert the wave energy into a steady current taking advantage of the properties of water waves. We will thus discuss how to generate a current from waves around a submerged structure (a thin plate). Wave dynamic above a submerged plate has been the object of numerous studies over the last five decades. Dick (1968) was the first to observe a reverse flow under the submerged plate breakwater. He was focusing on the feasibility of porous rectangular breakwater and observed in the limit case of 100% porosity (a submerged plate) a pulsating flow is generated seaward. In our work, we investigate the flow around a submerged plate due to wave action using the SPH method (Violeau 2012) : it is a Lagrangian numerical method particularly adapted for large deformations of a free surface flow. Figure 1 shows the numerical results for the experimental case of Murakami (1992). We will present a theoretical model to explain the observed flow based on wave mass transport.
