Özet:

 The study of wave energy conversion WEC technologies has been growing, with an emphasis on the overtopping device. Its operation is based on a ramp that directs wave water into an elevated reservoir. The accumulated water flows through a low-head tur-bine, generating electricity. This study proposes to develop a complete computational model to simulate a wave channel containing an overtopping device with a Savonius-type turbine inserted in the devices outlet duct. This study deals with the computa-tional modeling of a multiphase air and water, turbulent, incompressible flow with constant thermo-physical properties, generated by the movement of numerical ocean waves. Verificationvalidation studies were conducted to guarantee the reliability of the separated models: i flow in overtopping device without turbine, ii flow over a free Savonius turbine. After this step, the two models are coupled and results showed that the coupling was successful, allowing the observation of the flow behavior in the complete model. Despite that, the computational model still needs adjustments to the turbine rotation and outlet channel geometry.
