title: Modeling phase transitions in rapidly expanding systems
abstract: In this talk I first discus hydrodynamical simulations of relativistic heavy-ion collisions within the lab energy domain of (5-40) AGeV. The calculations are done within the 3d one-fluid model starting with cold nuclei in the initial state. Parameters of the compressed zone and matter trajectories in the temperature-density plane are calculated for two cases, with and without the deconfinement phase transition. An interesting observation is that in the equilibrium scenario the parameters of the
