摆动翼片机代表了一种类型的流动能量采集器，其同时执行俯仰和俯冲运动以利用来自进入流的能量。本文提出了一种新的自适应变形振荡机翼，并通过非定常二维模拟使用内部开发的计算流体动力学代码研究了这种概念的理论性能。在运行过程中，所提出的振荡翼的初始形状是对称的，可以变形成一个弯曲的翼，这旨在产生大的升力。我们的数值计算结果表明，拟议的振荡箔的功率效率可以比传统的振荡箔不变形约16.1%。此外，本文还讨论了最大弯曲位移和有效攻角对振荡翼效率的影响。
Oscillating foil machines represent a type of flow energy harvesters which perform pitching and plunging motions simultaneously to harness the energy from incoming stream. In this paper, a new adaptive deformation oscillating wing was proposed and the theoretical performance of such a concept was studied here through unsteady two-dimensional simulations using an in-house developed computational fluid dynamics code. During operation, the proposed oscillating foil whose initial shape is symmetric can be deformed into a cambered foil, which aims to produce large lift force. Our numerical results suggest that the power efficiency of the proposed oscillating foil can be about 16.1% higher than the conventional oscillating foil without deformation. In addition, the effects of the maximum bending displacement and effective angle of attack on the efficiency of proposed oscillating foil were also discussed in this work.
