Within the framework of the hydrodynamic approach, we carried out the investigation of a non-equilibrium equation of state. We noted the prospect of hydrodynamic approach in nuclear physics We considered the compression, expansion and freeze-out stages of a hot spot formed in heavy-ion collisions. The calculated energy spectra of protons produced in heavy-ion collisions have been compared with the experimental data for the different combinations of colliding nuclei in the energy range from a few tens to hundreds of MeV per nucleon, and with the results of calculations by the method based on the solution of the Vlasov-Uehling-Uhlenbeck (VUU) kinetic equation.
This work is dedicated to the Konstantin Alexandrovich Gridnev memory.
