| 摘 要： | 全被动式振荡水翼是振荡水翼式潮流能装置的主要型式之一。对全被动式振荡水翼进行了数值模拟研究，构建了二维数值模型，研究了雷诺数及升沉刚度对全被动式振荡水翼水动力性能的影响。通过流场结构及水动力性能分析研究了典型参量对全被动式振荡水翼获能性能的影响机理，确定了维持其良好水动力性能的参数范围。研究发现，水翼的水动力性能对雷诺数及升沉刚度的变化较为敏感。雷诺数增大，水翼所需升沉刚度随之增加，且水翼可以在更大的参数范围下获得较优的水动力性能。另外，水翼可以在没有升沉刚度的情况下实现周期性运动，其获能甚至优于一些有升沉刚度的情况。最优工况下，平均功率系数和能量转换效率分别为1.07和27.48%。

| Abstract: | Fully passive oscillating hydrofoil is one of the main types of oscillating wing tidal energy devices. The numerical simulation of the fully passive oscillating hydrofoil was carried out, and a two-dimensional numerical model was constructed to study the effects of Reynolds number and heave stiffness on the hydrodynamic performance of the fully passive oscillating hydrofoil. The influence mechanism of typical parameters on the energy acquisition performance of the fully passive oscillating hydrofoil was studied through the flow field structure and hydrodynamic performance analysis, and the parameter range to maintain its good hydrodynamic performance was determined. It is found that the hydrodynamic performance of hydrofoil is sensitive to the changes of Reynolds number and heave stiffness. With the increase of Reynolds number, the required heave stiffness of hydrofoil increases, and hydrofoil can obtain better hydrodynamic performance in a wider range of parameters. In addition, the hydrofoil can achieve periodic motion without heave stiffness, and its performance is even better than some cases with heave stiffness. Under the optimal conditions, the average power coefficient and energy conversion efficiency are 1.07 and 27.48%, respectively. |
