【摘要】：本文利用UCFD计算软件,对扑翼扑动获取潮流能进行了数值模拟研究。参照相关实验结果,进行数值模拟结果的确认。对不同系列翼型在水中获能变化进行了数值模拟和对比研究。结果表明:对于NACA 4系列、A系列和S系列翼型,获能效率随着叶片的厚度先逐渐增大后减小;对于所研究的NACA 6系列和FX系列基本随着翼型厚度的增大而增大;对于弯度相差不大的翼型,只要翼型厚度相近,且涡的形成与耗散方式相同,则其获能效率相近;对于相等厚度的翼型,翼型最大厚度的位置离尾缘越近,则翼型的获能效率会越低;对于薄翼型来说,对称翼型比不对称翼型有更高的获能效率;前缘涡在合适的位置生成与脱落,有利于提高翼型的升沉力和升沉力做功。
[Abstract]:In this paper, the numerical simulation of the tidal current energy obtained by flapping of flapping wings is carried out by using UCFD software. According to the experimental results, the numerical simulation results are confirmed. Numerical simulation and comparative study on different series of airfoils were carried out. The results show that for NACA _ 4 series A series and S series airfoils, the efficiency of energy acquisition increases gradually and then decreases with the thickness of the blade, while the NACA _ 6 series and FX series of the studied airfoil increase with the increase of the thickness of the airfoil. For airfoil with similar curvature, as long as the thickness of airfoil is close, and the vortex is formed in the same way as dissipation, the efficiency of obtaining energy is similar, and for airfoil of equal thickness, the position of maximum thickness of airfoil is closer to the trailing edge. For thin wing, symmetric airfoil has higher energy acquisition efficiency than asymmetrical airfoil, leading edge vortex is generated and shedded at suitable position, which is helpful to improve the lift force and heave force of airfoil.
