Abstract

The characteristics of the fluid dynamics of the two-dimensional square cylinder were investigated experimentally in case that the parameters were the blockage ratio and the gapratio s/h, where s means the gap between cylinder and plane wall, h the side length of the cylinder. The time-mean fluid force and fluctuating force the cylinder rapidly increased when the gap ratio was over the critical value (s/h)_cr. This critical value (s/h)_crcr decreased with the increase of the blockage ratio. It was also found in the visualization experiment that the Flow patterns around the cylinder were classified into two patterns on the boundary of this critical value.
