To improve the response-ability of the energy harvester to multidirectional wind, this paper proposes a wind energy harvester to scavenge wind-induced vibration energy. The harvester comprises a cylindrical beam instead of conventional thin rectangular cantilevers, a bluff body (square prism or circle cylinder), and a piezoelectric tube bonded to the bottom side of the beam for energy conversion. Benefiting from the symmetry of the cylindrical structure, this harvester can respond to airflow from every direction of the two-dimensional plane. The performance of the harvester under a wind speed range of 1.5-8 m/s has been tested. The results demonstrate that the proposed harvester can respond to the wind from all directions of the two-dimensional plane. It provides a direction for the future in-depth study of multidirectional wind energy harvesting.
为提高能量收集器对多向风的响应能力，本文提出一种用于 scavenge 风致振动能量的风能收集器。该收集器包括一个圆柱形梁而非传统的薄矩形悬臂梁、一个钝体（方柱体或圆柱体）以及一个粘结在梁底侧用于能量转换的压电管。得益于圆柱形结构的对称性，该收集器能够响应二维平面各个方向的气流。已测试了该收集器在 1.5 - 8 m/s 风速范围内的性能。结果表明，所提出的收集器能够响应二维平面所有方向的风。它为未来多向风能收集的深入研究提供了一个方向。
“scavenge”在这里结合语境推测可能是“收集、 scavenge（这里可能是想表达‘收集’之类意思，原词不太准确）” ，你可根据实际情况进一步确认。
