中文摘要：

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。

英文摘要：

By utilizing the UCFD software,this paper numerically investigated the energy extraction of flapping hydrofoil in current.Firstly,the simulation result was verified by comparing with related experimental results.Secondly,with different series of hydrofoil shapes,simulation was conducted for energy extraction of flapping foil moving harmonically in current.Several results were found in this research：for NACA 4,A and S series hydrofoils,the energy extraction efficiency basically increased first and then decreased with the increase of thickness of hydrofoil;for NACA 6 and FX series hydrofoils this paper studied,the energy extraction efficiency increased with the increase of thickness of hydrofoil;for hydrofoils with small difference of camber,if the hydrofoils had similar thickness and similar mode of formation and dissipation of vortex,the energy extraction efficiencies were close;for hydrofoils with the same thickness,the energy extraction efficiency decreased when the position of the maximum thickness of the hydrofoil was closer to the trailing edge;for thin hydrofoils,the symmetric hydrofoils showed higher energy extraction efficiencies than asymmetric hydrofoils;with generation and shedding of leading edge vortex at proper position,the energy extraction efficiency could be increased accordingly.
