| 中文摘要: |
| 近岸带的海域、海底和海岸都是不规则的,会引起波浪的不规则变形、折射、绕射和反射,使得波能分布不均匀,可能会影响波能装置的性能。本文基于小振幅波理论假设,从线性势流理论出发,用边界元方法研究地形对岸式波能转换装置(以下简称岸式装置)的水动力性能的影响。计算结果表明,地形的影响是非常大的,不可忽略。一些带前港的地形对提高岸式装置的转换效率很有价值。本文理论对地形无任何限制,因而提供了一个在线性理论范围内模拟复杂地形条件下装置附近流场的方法,同时说明此计算方法对波能电站的设计和工程选址有一定的参考价值。 |

| In the near-shore,the irregular sea bed and coast line could wave shoaling,wave refraction,diffraction,reflection,and so on,which may wave energy distribute unevenly,and may influence of wave power devices.In this paper a boundary element method based on small-amplitude wave theory and linear potential theory are utilized to study the topographic effects on hydrodynamic characteristics of shore-mounted wave-power devices.Numerical results have shown that the effects of topography nearby the device are quite great and can not be neglected.Some harbor-like topographies can be made use of to increase the efficiency of the shore-mounted wave-power devices.The theory adopted in this paper does not impose restrictions on the topography near the device,which provides an effective method simulating the fluid flow field nearby the device with complicated topography.The method proposed in this paper has been proved useful for practical engineering to design wave-power stations. |
