Te space-time analogy shared by a group of self-similar structure vortices is discussed. The governing equations were reduced into general form by extending the steady-state n family and Sullivan's vortex into time decaying. Reversing of the process; the steady-state group that gives rise to the diffusing Bellamy-Knights set of vortices is also recovered. The steady vortex formulation of the group is due to Rankine. The model assumes both the radial and axial velocity components to be zero; suggesting a linear distribution inside the core; and a hyperbolic variation outside. A solution in terms of a hypergeometrics series was given by Kirde. Vatistas et al. recently laid the fundamental of transformations;
