J. Bernsdorf et al., Simulation of a 2D channel flow around a square obstacle with lattice-Boltzmann (BGK) automata, INT J MOD C, 9(8), 1998, pp. 1129-1141
Results for time-dependent, viscous, incompressible flows were investigated
using the lattice-Boltamann (BGK) automata. The decay of a synthetic turbu
lent flow field and the time evolution of an initial vortex were simulated
for validation purposes. The focal point was the investigation of the insta
tionary flow around a square obstable in a two-dimensional channel for a ra
nge of Reynolds numbers between 80 and 300 and a blockage ratio of 0.125. T
he Strouhal number was measured for this case and found to be in the range
of data given in the literature.
