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.
