Numerical Study on Performance Analysis for OWC WEC Applicable to Breakwater

Abstract

The present paper introduces CFD (Computational Fluid Dynamics) analysis results to evaluate the performance of the sloped OWC (Oscillating Water Column) chamber. The CFD analysis method is validated by comparing the results of the 2D waveflume model test for the opened chamber without considering the turbine interaction. The performance of the sloped OWC chamber is evaluated through the 3D CFD analysis by modelling the orifice to take into account the interaction between turbine and oscillating water column in the chamber for various size of the orifice.
