摘要/Abstract

摘要： 中心管波浪能模型利用浮体自身振荡运动吸收波浪能,使管内水柱产生相对运动,通过外加气动阻尼转换俘获的波浪能。运用HydroStar水动力学软件计算了直管型中心管模型在不同波况下的水动力学性能,对比分析了不同外加气动阻尼对模型俘获宽度比的影响,得到了最佳气动阻尼;研究了模型在3种不同总质量下的性能,得到了最佳响应波周期与模型总质量的关系。在波浪水槽中测试了中心管模型的俘获宽度比,实验结果进一步验证了数值计算结果的准确性。

关键词: 波浪能, 振荡水柱, 数值计算, 中心管, 俘获宽度比

Abstract: The spar buoy wave energy model absorbs the wave energy by the self-oscillating motion of the floating body. The relative motion of the water column in the pipe was caused and the captured wave energy is converted by the added pneumatic damping. It can be studied as an oscillating single floating buoy. HydroStar hydrodynamics software is used to calculate the hydrodynamic performance of the straight center pipe model under different wave conditions. The effect of different added pneumatic damping on the Capture Width Ratio （CWR） of the model is compared and analyzed, and the optimal pneumatic damping is obtained. The performance of the model under three different total masses is studied, and the relationship between the optimal response wave period and the total mass of the model is obtained. The CWR of the spar buoy model was tested in a wave tank, and the experimental results obtained can further verify the numerical calculation results.

Key words: wave energy, oscillating water column （OWC）, numerical calculation, spar buoy, capture width ratio （CWR）
