Note (General): By solving the three-dimensional incompressible Navier-Stokes equations, the development of three-dimensionality was investigated in a flow around a circular cylinder placed between side walls. Also, the case of a circular cylinder with an infinite spanwise length was treated using a periodic boundary condition. Initial vortex development and the development of spanwise vortical-pattern are intensively visualized to see the three-dimensional structure. In the initial stage, the flow was almost two-dimensional. The two-dimensionality was kept in the first separation but as the flow developed, the wake became strongly three-dimensional. Also, in the developed stage, a large horse-shoe vortex was observed in front of the cylinder near the wall.
