Effects of side ratio on energy harvesting from transverse galloping of a rectangular cylinder
Yu, Haiyan; Zhang, Mingjie (Peer reviewed; Journal article, 2021)Rectangular cylinders have been identified as ideal bluff bodies for galloping-based energy harvesting, while a systematic study of the effects of the side ratio (i.e., the ratio between the cylinder width and the cylinder ... -
Experimental Investigation on Glaze Ice Accretion and Its Influence on Aerodynamic Characteristics of Pipeline Suspension Bridges
Yu, Haiyan; Xu, Fuyou; Zhang, Mingjie; Zhou, Aoqiu (Peer reviewed; Journal article, 2020)Pipeline suspension bridges may experience ice accretion under special atmospheric conditions, and the aerodynamic characteristics of the bridges may be modified by the ice accretion. Under some specific climatic conditions ... -
Piezoelectric energy harvesting from vortex-induced vibration of a circular cylinder: Effect of Reynolds number
Zhang, Mingjie; Zhang, Chengyun; Abdelkefi, Abdessattar; Yu, Haiyan; Gaidai, Oleg; Qin, Xiang; Zhu, Hongjun; Wang, Junlei (Peer reviewed; Journal article, 2021)This study investigates the effects of the Reynolds number on the piezoelectric energy harvesting from vortex-induced vibrations (VIV) of a circular cylinder. The VIV-based piezoelectric energy harvester is simulated by a ... -
Predefined angle of attack and corner shape effects on the effectiveness of square-shaped galloping energy harvesters
Zhang, Mingjie; Abdelkefi, Abdessattar; Yu, Haiyan; Ying, Xuyong; Gaidai, Oleg; Wang, Junlei (Peer reviewed; Journal article, 2021)Energy harvesting based on transverse galloping of a square cylinder has been widely studied while the effects of angle of attack and corner shape remain unclear. This study proposes to explore the impacts of these two ... -
A simplified model to evaluate peak amplitude for vertical vortex-induced vibration of bridge decks
Zhang, Mingjie; Xu, Fuyou; Yu, Haiyan (Peer reviewed; Journal article, 2021)A simplified model is developed to conveniently evaluate the peak vortex-induced vibration (VIV) amplitudes of a bridge deck at various mass-damping conditions. As a simplified form of the describing function-based model ...
