现有波浪能浮子装置的研究易忽视其表面波浪爬升对自身造成的损害,针对此问题,试验以分段环形浮子为研究对象,从周期和吃水两个方面探讨对波浪爬升的影响,结论表明：当入射波周期接近分段环形浮子的固有周期时,波浪爬升显著增加;同时波浪爬升随吃水的增加而增加,增加幅度与波周期有关。此外试验探究了特定工况下浮子周围波场的分布特征,表明垂荡运动的分段环形浮子对迎浪侧的波浪场影响较明显,仅对背浪侧有限范围内的波浪场产生影响。
Abstract
Most existing studies on wave energy converters （WECs） have failed to account for structural damage induced by wave run-up on the buoy surface. To address this issue, the modeling test is conducted on a segmented annular buoy to quantify the influences of wave period and draft on wave run-up characteristics. The experimental results demonstrate that wave run-up is significantly amplified when the wave period approaches the natural period of the segmented annular buoy. Wave run-up also exhibits a monotonic increase with growing draft, where the magnitude of the increase is strongly dependent on the wave period. Furthermore, analysis of wave field distribution around the buoy under specific conditions demonstrates that the heave motion of the segmented annular buoy predominantly affects the wave field on the wave-ward side, while its effect on the leeward is restricted to a narrow range.
