针对岛礁附近海域陡变海底地形对振荡浮子波浪能装置水动力性能的影响,采用物理模型试验和计算流体动力学（CFD）方法进行研究。在波浪水槽试验中,构建具有斜坡底的礁盘模型,并以平坦地形作为对照组,系统分析入射波波高、周期及装置布放位置对装置性能的影响。同时,建立CFD数值波浪水槽,通过与试验数据对比,验证数值模型的准确性。研究结果表明,在长波区,相较于平坦地形,陡变海底地形可显著提高装置的俘获宽度比。
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.
