A numerical study of uniform flow past a row of rectangular rods with aspect ratio defined as R=width/height=0.5 is performed using the Lattice Boltzmann method. For this study the Reynolds number (Re) is fixed at 150, while spacings between the rods (g) are taken in the range from 1 to 6. Depending on g, the flow is classified into four patterns: flip-flopping, nearly unsteady-inphase, modulated...
Two-dimensional numerical study has been carried out to investigate the effect of gap spacings for flow past five side-by-side rectangular cylinders using the lattice Boltzmann method at a Reynolds number of 150 and aspect ratio defined as AR=length/height=1.5. The gap spacing between the cylinders is varied systematically from g=0.5 to 4, so that the sensitivity of the flow and force statistics can...
