摘要

采用数值分析和田口方法相结合的方法系统研究V形交错布局对扑翼捕能性能的影响。结果表明：相对于单翼

田口试验方法优化后的V形交错布局扑翼的捕能效率提高16.48%。所研究的5个特征参数对扑翼捕能性能的影响程度依次为：\phi L_{x} L_{y} \theta_{0} f^{*}

表明前后扑翼间的相位差对扑翼性能的影响最大

扑动频率对扑翼性能的影响最小。通过对扑翼周围的流场结构分析发现

在最佳特征参数组合下

下游翼可在前翼脱落涡的作用下获得更大的动压力

从而使群体扑翼捕获更多的能量。

Abstract

Numerical analysis and Taguchi method are applied to investigate the impact of the V-shaped staggered configuration on the energy harvesting performance of the flapping hydrofoil. The results show that the three hydrofoils in a V-shaped group configuration with optimum parameters increased the output efficiency by 16.48% compared with the single hydrofoil. Meanwhile

the influence degree of the five parameters considered in this work on the performance can be ordered as \phi L_{x} L_{y} \theta_{0} f^{*}

which means that the phase difference between upstream and downstream hydrofoil has the greatest impact on the output performance of the flapping hydrofoil and that of the flapping frequency is weakest. The analysis of the flow field structure around the flapping hydrofoil reveals that under the optimal combination of characteristic parameters

the greater dynamic pressure can be obtained by the downstream hydrofoil

which is induced by the shedding vortex of the upstream hydrofoils

and it is the reason why the group flapping hydrofoil can extract more energy.
