| 摘要: |
| 为实现对海上风电场中潮流能有效利用,提出一种将振荡水翼潮流能捕获装置与海上风力机水下塔筒结合的摆式振荡翼塔筒尾涡潮流能捕获系统。联合格子玻尔兹曼和大涡模拟方法,对NACA0015翼型在有无塔筒尾流效应时,不同运动参数对其水动力特性及能量收集效率的影响进行数值分析,并从水翼运动过程中的旋涡结构分析了俯仰振幅、升沉振幅及振荡翼弦长对系统捕能效率的影响。结果表明,塔筒尾涡显著提升振荡翼的能量收集效率,同时振荡翼的加入能减慢塔筒涡脱,降低由钝体绕流引起的疲劳载荷。摆式振荡翼在塔筒尾涡区域内的捕能效率最高可达30.72%,与传统振荡翼潮流能捕获装置相比具有明显优势,为提高海上风场整体能源利用率提供了一种有效的方式。 |

| Abstract: |
| In order to effectively utilize the tidal current energy in offshore wind farms, a swing oscillating hydrofoil system for tidal current energy capture is proposed. The system is constructed with oscillating hydrofoils as tidal current energy capture device combined with offshore wind turbine underwater tower. Lattice Boltzmann method and large eddy simulation method were combined, and the hydrodynamic characteristics and energy collection efficiency of a NACA0015 airfoil with different motion parameters were numerically analyzed with or without the influence of tower wake. The influence of pitch amplitude, heave amplitude and chord length of the hydrofoil on the energy collection efficiency of the system is analyzed from the aspect of vortex structure in the moving process. The results show that the energy collection efficiency of the oscillating wing is significantly improved by the trailing vortex of the tower, and the vortex shedding behind the tower can reduced by the addition of the oscillating wing, consequently, the fatigue load caused by the flow around the cylindrical body can be reduced. The energy capture efficiency of the oscillating wing can reach a highest efficiently of 30.72% in the wake vortex region of the tower, which has obvious advantages compared with the traditional oscillating wing tidal current energy capture device, and provides an effective way to improve the overall energy utilization rate of offshore wind farms. |
