Two-dimensional numerical simulation of wind driven ventilation across a building enclosure with two free apertures on the rear side: Vortex shedding and “pumping flow mechanism”
TL;DR: In this article, the authors investigated the single-sided wind driven natural ventilation with two apertures on the rear wall, regarding different horizontal aperture separations, magnitudes of incoming wind speed and various side ratios (L/D, length/width).

Wind-driven pumping flow ventilation of highrise buildings: Effects of upstream building arrangements and opening area ratios.
TL;DR: Numerical results indicate that the strength of "pumping" flow could be intensively weakened by two upstream buildings, and the study on the wake vortex shedding flow across building clusters could benefit the future green design of urban buildings.

Strouhal numbers of rectangular cylinders
TL;DR: In this article, experiments on the vortex shedding frequencies of various rectangular cylinders were conducted in a wind tunnel and in a water tank and the results show how Strouhal number varies with a width-to-height ratio of the cylinders in the range of Reynolds number between 70 and 2 × l04.

Interference between two circular cylinders; Series of unexpected discontinuities
M.M. Zdravkovich,D.L. Pridden +1 more
TL;DR: In this paper, the authors investigated the effect of different flow patterns on the front and base pressures of two cylinders arranged side-by-side to the approaching flow and found that the biased flow was bistable causing a change over at irregular intervals.
