为了改善水翼的水动力性能,提高振荡翼的能量转化效率,基于传统运动模型提出了改进模型.利用Fluent建立了翼型的网格模型,并从水翼在运动过程中攻角(AOA)的变化及漩涡结构等方面分析了改进模型在不同运动参数下的水动力性能及能量转化效率.结果表明:改进模型在较长时间段内维持较大的升力系数,提高了水翼的水动力转化效率.与传统运动模型相比,在相同的最大攻角下,提出的改进模型有更好的水动力性能,且其能量转化效率超过40%.
In order to improve the hydrodynamic performance of hydrofoil and improve the energy conversion efficiency of the oscillating wing, an improved model is proposed based on the traditional motion model.The airfoil grid model is established by using Fluent, and the airfoil angle of attack (AOA) The hydrodynamic performance and the energy conversion efficiency of the improved model under different motion parameters were analyzed.The results show that the improved model maintains a larger lift coefficient over a longer period of time and improves the hydrodynamic performance of the hydrofoil Conversion efficiency Compared with the traditional model, the improved model proposed at the same maximum angle of attack has better hydrodynamic performance and its energy conversion efficiency exceeds 40%.
