    "abstract": "A dynamical appearance of scaling solutions in the relativistic hydrodynamics\napplied to describe ultra-relativistic heavy-ion collisions is studied. We\nconsider the boost-invariant cylindrically symmetric systems and the effects of\nthe phase transition are taken into account by using a temperature dependent\nsound velocity inferred from the lattice simulations of QCD. We find that the\ntransverse flow acquires the scaling form r/t within the short evolution times,\n10 - 15 fm, only if the initial transverse flow originating from the\npre-equilibrium collective behavior is present at the initial stage of the\nhydrodynamic evolution. The amount of such pre-equilibrium flow is correlated\nwith the initial pressure gradient; larger gradients require smaller initial\nflow. The results of the numerical calculations support the phenomenological\nparameterizations used in the Blast-Wave, Buda-Lund, and Cracow models of the\nfreeze-out process.",
