  Heavy-ion collisions performed in the beam energy range accessible by the
NICA collider facility are expected to produce systems of extreme net-baryon
densities and can thus reach yet unexplored regions of the QCD phase diagram.
Here, one expects the phase transition between the plasma of deconfined quarks
and gluons and the hadronic matter to be of first order. A discovery of the
first-order phase transition would as well prove the existence of the QCD
critical point, a landmark in the phase diagram. In order to understand
possible signals of the first-order phase transition in heavy-ion collision
experiments it is very important to develop dynamical models of the phase
transition. Here, we discuss the opportunities of studying dynamical effects at
the QCD first-order phase transition within our model of nonequilibrium chiral
fluid dynamics.
