Description

In different energy domains the collision of two heavy nuclei has to be described with different models. A three-component fluid model is introduced for heavy ion reactions to determine the viscosity term and the entropy production of the process. The entropy production turns out to be connected with the modified two-nucleon scattering cross section, while the viscosity coefficient is related only to the densities and to the velocity gradients, as in ordinary hydrodynamics.
