摘要: The effect of a finite mean free path on the expansion stage central collisions between heavy nuclei is studied in nonrelativistic fluid dynamical approach. A gas point particles with localized interactions used. Kinetic theory then provides thermal conductivity and viscosity coefficients terms nucleon-nucleon cross section. About 10% additional entropy generated during at beam energy 800 MeV/A due to viscous heating system. Surprisingly there only weak dependence mass colliding nuclei. These results are substantial agreement recent intranuclear cascade calculations, although present slightly ambiguous an uncertainty breakup criterion.
