Hubble-like Flows in Relativistic Heavy-Ion Collisions
We study the dynamical appearance of scaling solutions in relativistic hydrodynamics. The phase transition effects are included through the temperature dependent sound velocity. If a pre-equilibrium transverse flow is included in the initial conditions, then it may reach the form of the asymptotic Hubble flow, r/t, in short evolution times, 7–15 fm. The numerical solutions are found to support the freeze-out models (Blast-Wave, Buda-Lund, Cracow).
