TEMPERATURE AND HEAT CONDUCTIVITY IN CELLULAR AUTOMATA FLUIDS

After introduction of the concept temperature, consistent with thermodynamics and irreversible thermodynamics, Green-Kubo formulas are derived for the heat conductivity and the viscosities and evaluated in Boltzmann approximation. The bulk viscosity vanishes identically. The conservation laws determine which gradients of thermodynamic variables should be considered as driving forces, and guarantee transport coefficients consistent with irreversible thermodynamics.
