Wave energy converter optimization by CFD simulation
Ocean wave energy has the potential of contributing significantly to the industrial energy production and export, both as a stand alone solution by using wave energy converters (WECs) in wave energy parks, and in combination with offshore wind energy. For comparison the power intensity of wind is 0.4 0.6 kW/m 2 , solar is 0.1 0.2 kW/m 2 and wave power intensity is about 2 3 kW/m 2 [1, Wave energy converter Crestwing is an attenuator type of WEC with proven technology and simple feasibi lity originated from shipbuilding industry [3]. Although it seems to be a feasible technology it still has many avenues for optimizing efficiency and minimizing costs to drive down levelized cost of electricity. E ffective energy harvesting is only conceiva ble by interpretation of underlying physics and optimization of key parameters of a WEC such as hull shape. For these goals we use state of the art CFD simulation tools based on fifth order Stokes wave theory, overset mesh technique and dynamic fluid body interaction. At the symposium we will present verification and validation of the CFD model relying on existing model tests and use the CFD results to highlight the key components of the Crestwing WEC [4, 5].
