| 摘要: |
| 为探讨不同地形特征对单浮子集成装置水动力特性的影响，本文基于黏性计算流体动力学理论，应用Star-CCM+软件建立二维数值波浪水槽，研究了规则波作用下受不同地形影响的单浮子式防波堤与波能转换装置集成系统的水动力性能。结果表明：在低频区，不同地形下单浮子集成系统的波能转换效率均大于无地形影响下单浮子集成系统的波能转换效率；在高频区，浮子无法及时响应高频波，浮子与波浪异向运动，对于大部分情况，不同地形下集成装置的波能转换效率和透反射系数均小于无地形影响下集成系统的相应参数。地形坡度、宽度和高度对单浮子集成装置水动力性能影响不显著。 |

| Abstract: |
| A two-dimensional numerical model was established using the Star-CCM+software-based viscous computational fluid dynamics theory to investigate the hydrodynamic performance of a single-floater integrated system in different terrains under regular waves.The results indicate that in low frequency areas,the wave energy conversion efficiency of the single-float integrated system under different terrains is greater than that of the single-float integrated system without a terrain.In the high-frequency region,the floater cannot respond to high-frequency waves on time and moves in various directions because of the waves.In most cases,the wave energy conversion efficiency and the transmission and reflection coefficients of the integrated device under different terrains are less than the corresponding parameters of the integrated system without the influence of a terrain.The slope,width,and height of the terrain have no significant influence on the hydrodynamic performance of the single-float integrated device. |
