Tree-inspired piezoelectric energy harvesting
William B. Hobbs,David Hu +1 more
TL;DR: In this article, a uniform flow vibrates a linear array of four cylinders affixed to piezoelectric energy transducers, and the energy generated by downstream cylinders can exceed that of leading cylinders by more than an order of magnitude.

Flow-induced vibrations of a side-by-side arrangement of two flexible circular cylinders
TL;DR: In this article, a side-by-side arrangement of two vertical, high aspect ratio (length over diameter) and low mass ratio (mass over mass of displaced fluid) cylinders, pin-jointed at the ends and vibrating at low mode number, was carried out in a free-surface water channel.

Two circular cylinders in cross-flow: A review
TL;DR: The current understanding of the flow around two infinite circular cylinders of equal diameter immersed in a steady cross-flow, with a focus on the near-wake flow patterns, Reynolds number effects, intermediate wake structure and behaviour, and the general trends in the measurements of the aerodynamic force coefficients and Strouhal numbers are reviewed in this paper.
Journal ArticleDOI
The effects of interference between circular cylinders in cross flow
TL;DR: In this article, an attempt is made to categorize various cluster arrangements in terms of the number of pipes (cylinders), their mutual spacing and orientation to the oncoming current.
Journal ArticleDOI
Flow induced oscillations of two interfering circular cylinders
TL;DR: In this paper, a systematic classification of flow interference regimes is linked to the observed vortex shedding responses for a wide range of arrangements, and all types of the fluid-elastic oscillations were related to the regions of interference.
Journal ArticleDOI
Flow-pattern identification for two staggered circular cylinders in cross-flow
TL;DR: In this paper, the authors used flow visualization and particle image velocimetry to investigate the flow around two circular cylinders of equal diameter arranged in a staggered configuration, and found that vortex shedding frequencies are more properly associated with individual shear layers than with individual cylinders.
