Abstract

A systematic study investigates the impact of abrupt seabed topography near reef areas on the hydrodynamic performance of oscillating buoy wave energy converters, using physical model experiments and computational fluid dynamics （CFD）. In the wave flume experiments, a reef-flat model with a sloping seabed is constructed, with a flat seabed as the control group. The effects of incident wave height, period, and device deployment position on performance are analyzed. A numerical wave flume is developed, and its accuracy is validated through comparison with experimental data. The results indicate that, in the long-wave region, abrupt seabed topography significantly enhances the capture width ratio compared to flat seabed conditions.
