Abstract
The temperature dependence of the kinetic coefficients is obtained in the nonperturbative region with the help of Green-Kubo-type formulae i n the model of massive gluon gas motivated by numerical results from s imulations of lattice QCD. The entropy production rate is estimated us ing scaling hydrodynamics. It is shown that the increase in the viscos ity coefficients leads to entropy generation in heavy ion collision pr ocesses which could be big, especially for temperatures close to the c ritical one.
