| Abstract: | The transition features of the wake behind a uniform circular cylinder at \%Re\%=200, which is just beyond the critical Reynolds number of 3\|D transition, are investigated in detail by direct numerical simulations of 3\|D incompressible Navier\|Stokes equations. The spanwise characteristic length determines the transition features and global properties of the wake. |
