Prédiction déterministe de houle en temps réel par mesure du profil de vitesses horizontales

Abstract : Optimizing the production of wave energy converters using Model Predictive Control (MPC) requires a real-time, deterministic prediction of the waves arriving on the device. This study presents a new method for deterministic wave prediction, using the horizontal velocity profile over the water column as a limit condition for a deterministic wave model. However, direct measurement of the horizontal velocity profile is hardly achievable in practice: a method to reconstruct this profile from more realistic measurements is thus presented and evaluated. The performance of the prediction method itself is then tested numerically. The simulations compared respectively use a perfect and a reconstructed horizontal velocity profile as limit conditions. The results show that the method is promising enough to justify further investigation through wave tank experiments.
