At a critical point, like the one conjectured for QCD, the correlation length of fluctuations of the order parameter diverges in thermodynamic systems. In dynamical systems nonequilibrium effects weaken critical phenomena. In order to provide solid predictions for event-by-event fluctuations of observables studies of dynamical systems are crucial to guide the search for the discovery of the critical point in heavy-ion collision experiments, like the beam energy scan at RHIC, BNL. Fluid dynamics has been very successful in explaining a variety of data from heavy-ion collision experiments. It is especially suitable because the order parameterat at the critical point can be described as a collective variable within a fluid dynamical setup. In this talk I will review recent advances in our understanding of the phase transition obtained within fluid dynamical models and outline possible approaches to future contributions to the search for the QCD critical point.
