  New results obtained for thermal conduction in 2D Yukawa systems. The results
of numerical study of heat transfer processes for quasi equilibrium systems
with parameters close to conditions in laboratory experiments with dusty plasma
are presented. The Green-Kubo relations are used to calculate thermal
conductivity and diffusivity coefficients. For the first time the influence of
dissipation (friction) on the heat transfer in non-ideal systems is studied.
New approximation is suggested for thermal diffusivity. The comparison with the
existing experimental and numerical results is shown.
