Computational simulation of the flow-induced vibration of a circular cylinder subjected to wake interference
TLDR
In this paper, the authors considered the flow around two circular cylinders of equal diameter placed in tandem with respect to the incident uniform flow, and performed two-and three-dimensional simulations of this flow using a Spectral/hp element method to discretise the flow equations, coupled to a simple Newmark integration routine that solves the equation of the dynamics of the cylinder.About:

Flow-induced vibration of two cylinders in tandem and staggered arrangements
TL;DR: In this paper, a numerical study of the flow-induced vibration of two elastically mounted cylinders in tandem and staggered arrangements at Reynolds number Re = 200 is presented, where the cylinder centres are set at a streamwise distance of 1.5 cylinder diameters, placing the rear cylinder in the near wake region of the front cylinder for the tandem arrangement.

Vortex-induced vibrations of three tandem cylinders in laminar cross-flow: Vibration response and galloping mechanism
TL;DR: In this article, the authors numerically studied the vortex-induced vibrations of three tandem cylinders using the immersed boundary method and found that, in the case of small L ∕ D, large-amplitude vibrations of the cylinders are excited due to strong wake-cylinder interference.

Wake-induced vibrations of an elastically mounted cylinder located downstream of a stationary larger cylinder at low Reynolds numbers
TL;DR: In this article, two unequal-sized circular cylinders in tandem arrangement are performed at low Reynolds numbers (Re), where the upstream larger cylinder is stationary, while the downstream cylinder has both one (transverse-only) and two (transversal and in-line) degrees of freedom (1-dof and 2-of, respectively).
