Large eddy simulation of flow around two side-by-side circular cylinders at Reynolds number 3900
TL;DR: In this paper , the authors investigated the flow dynamics around two circular cylinders in side-by-side arrangement with different spacing ratios under a subcritical Reynolds number condition and found that vortex shedding manner during the flip-over transitions is closely related to the spacing ratios, and is independent of the Reynolds number.

Evidence and physical mechanism for vortex-induced vibration of a bluff body without an afterbody
TL;DR: Zhao et al. as discussed by the authors showed that even without an afterbody, an elastically mounted triangular prism with one vertex pointing upstream can freely vibrate, in contrast to the VIV of a circular cylinder with an after-body in which the viscous component always results in energy dissipation and damps the vibration.

Wavelet Transforms and their Applications to Turbulence
TL;DR: Wavelet transforms are recent mathematical techniques, based on group theory and square integrable representations, which allows one to unfold a signal, or a field, into both space and scale, and possibly directions.

On the drag and shedding frequency of two-dimensional bluff bodies
TL;DR: In this paper, a semi-empirical study of the bluff body problem is presented, where interference elements in the wake close behind a cylinder demonstrate the need for considering that region in any complete theory.

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.
