摘要：Large Eddy Simulations (LES) of the three-dimensional flow around fixed bluff bodies
have been performed in two benchmarks: a square cylinder (case A) and a wall-mounted
cube (case B), as denoted by Rodi et al. (ASME transaction, vol. 119, pp. 248-262, June
1997). Due to some differences in the flow modeling, in this communication case A is
considered while in a companion work the results for the other case are shown. In case A,
the flow around a square cylinder, experiments show a typical unsteady-flow regime with
a periodic wake (the von Kármán vortex street) although there is some modulation on the
periodicity. The selected flow conditions for the present numerical simulations are taken
from those suggested by Rodi et al. Time-averaged and instantaneous flow visualizations
are used to clarify the flow behavior and are then contrasted to the experiment ones.
