Hydrodynamic of surge wave energy converters

Abstract

Ocean wave energy is a new renewable energy resource which is going to become one of the reliable and alternative resources for fossil fuels during recent decades. The majority of studies have focused on extract wave energy at an effective rate; whilst, there are a few studies to explore the hydrodynamic of wave and surge wave energy converters. In this study a 2D numerical model based on RANS equations is closured with SST turbulence model employed to simulate the hydrodynamic of the flap type wave energy devices. The results indicate that a partially standing wave induced by the interaction of incident and reflected waves occurs in front of device due to its rotating movements.
