The flow generated by a viscous incompressible fluid past an impulsively started circular cylinder at the Reynolds number 1000 (based on free-stream velocity and the cylinder diameter) is visually described for several time steps of integration by means of computer generated images of the vorticity field. The flow-field representations are based on the results of a computational code in which a mixed spectral-finite analytic technique is used for the numerical integration of the two-dimensional time-dependent Navier-Stokes equations. The mutual interaction of the primary vortices in the near wake of the cylindrical body, as a fundamental mechanism of the vortex shedding phenomenon, is demonstrated.
