Near-wake flow characteristics of two side-by-side circular cylinders close to a wall

Spectral shortcut in turbulence energy transfer in open channel flow over submerged vegetation

“…However, for the flow passing by vegetation arrays, the F (f) shows a spectral plateau, rather than any clear peaks at the fwake (Figs 3b & 3d). The spectral plateau occurs because the wake vortex shedding is being affected by the proximity of the neighboring cylinders (Nepf, 1999;Chen, 2011).…”
